(Conventional technology) Conventionally, from a viewpoint of aiming at the rigid rise of the bonding link of a pillar and a side sill in a car, as the interior space is divided into the bonding link, that from which Establishment constituted the paragraph with the reinforcement wall is known in the reinforcement wall (for example, refer to JP,61-183781,U). (Object of the Invention) By the way, it is although the rigid rise of the front portion of the body is aimed at and also it is necessary in a car, especially a convertible to fully secure the rigidity in the bonding link of a front pillar and a side sill of course, It is important to increase also to it and to fully secure the rigidity of the front pillar itself and rigidity [ in / above all / the direction of body order ]. However, a chief aim sets to aim at the rigid rise of the bonding link of a front pillar and a side sill so that it may be conventionally indicated by the above-mentioned well-known example, It is seldom taken into consideration about the point of the rigid rise of the front pillar itself, but has the room for an improvement in the field of the improvement in body rigidity of a car. then -- easy composition realizes simultaneously and the present invention has the rigid rise of the pillar member itself, and the rigid rise in 2 gos of Connection part of the pillar member and side sill -- the improvement in body rigidity -- it is going to plan -- it is a thing. (Means for solving problem) In order to solve such a subject, it is at the present invention, In the car which connects the side sill provided towards the direction of body order in the pillar part and car body side part which are provided towards the up-and-down direction in a car body side part in the lower end part of the pillar part, While forming two closed sections which divide the inside of the above-mentioned pillar part by the partition member prolonged in the up-and-down direction, and adjoin in the direction of body order, the above-mentioned partition member was installed in the above-mentioned side sill, and the inside of a side sill was divided in the direction of body order by the extendedly installed part. (OPERATION) It has such composition, (1) As compared with the case where a pillar part constitutes the inside from a place where two closed sections are moreover formed in the inside just before or after the direction of body order in one closed section, for example, the section performance in the direction of body order is improved, (2) Since the partition member which divides the inside of a pillar part and constitutes two closed sections extended in the side sill further and it has divided in the direction of the side sill body order by the extendedly installed part, The operation of etc to which a paragraph is formed in at the bonding link of the side sill and pillar part of the extendedly installed part of the partition member by which extension arrangement of the closed section of the above-mentioned pillar part was carried out into (3) side sills by which expansion installation is carried out not only the inside of the pillar part but into the above-mentioned side sill, and the rigidity of the portion is improved is obtained. (EFFECT OF THE INVENTION) Therefore, according to the front part car body construction of the car of the present invention, it is, (1) Expansion installation of this closed section was carried out into the side sill, and the capacity expansion was aimed at [ having formed in the inside of a pillar part two closed sections which adjoin in the direction of body order each other and having improved the section performance in the direction of body order of the pillar part, and ], The rigidity of the bonding link is improved by having formed the paragraph in both bonding link by the rigidity of the pillar part, and the partition member to which the rigidity of the direction of body order is improved especially and which is prolonged ranging over the inside of a side sill from the (2) pillar-part side, It is suitable as front part car body construction of the convertible by which the effect that the rigidity as the whole body is improved more effectively is acquired from the place which the rigid rise in the bonding link of a rigid rise and the pillar part of a etc, pillar part itself, and a side sill can aim at simultaneously, and high rigidity is required especially of a car body front. (EXAMPLE) Hereinafter, the suitable example of the present invention is described with reference to Drawings 1 thru/or 6. The body important section of the convertible provided with the front part car body construction concerning the example of the present invention is shown in Drawing 1, In the figure, numerals 1 are the side sills provided in the car body side part towards the direction of body order, and it is front end part 1a of the side sill l, It is combined to pillar part P which consists a car body side part of front pillar 2 prolonged in the up-and-down direction, hinge pillar 3 mentioned below, and Cowl side panel 4, and the front end corner part of door opening 30 is constituted. In Drawing 1, numerals 5 are front frames with which provide a dash lower panel and 6 in a Damyu upper panel, 7 is provided in a wheel apron reinforcement, and 8 is provided in the front side of the wheel Apron information Sumendoa. and -- a thing of this example applies the present invention -- a rigid rise of the above-mentioned pillar part, and a rigid rise of a bonding link of the pillar part and side sill -- simultaneous -- it is going to plan -- it is a thing. Hereinafter, outside Drawing 1, Drawings 2 thru/or 6 are used together and concrete composition for the above-mentioned rigid rise is explained in full detail. Side sill I constitutes a closed section from side sill outer panel 11 and side sill inner panel 12, as shown in Drawings 1 and 3 and Drawing 4, respectively, By carrying out abbreviated and curving in a form, the front end part 1a carries out the opening of the upper end part toward the upper part, in order to combine hinge pillar 3 mentioned below. Front pillar 2 constitutes a closed section from a king of front pillar outer Penel 13, front pillar inner panel 14, and front pillar reinforcement 15, as shown in Drawings 2, 3, and 5, and it is provided in a car body side part towards the up-and-down direction. In the lower end part of this front pillar 2, Hinge pillar outer panel 16 which has an approximately Co type section and is attached to the lower end part of above-mentioned front pillar outer Penel 13 by the successive state, Hinge pillar 3 which consists of hinge pillar inner panel 17 which has an approximately Ri type section and is attached to the edge 16a side of body front slippage of the hinge pillar outer panel 16 in the state of extension (refer to the 6th figure) is provided. and -- while the lower end part of this hinge pillar 3 is attached to the above-mentioned side sill front end part 1a in the state where it was inserted between side vine outer panel 11 of the side vine 1, and side sill inner panel 12 Cowl side panel 4 is joined to the side sill front end part 1a and hinge pillar outer panel 16 from the body side side. Pillar part P in a claim comprises three persons of this front pillar 2, hinge pillar 3, and Cowl side panel 4. Thus, in the state where pillar part P and side sill l were combined, as shown in Drawing 2, two closed sections, closed section 31 and closed section 32, which adjoin in the direction of body order by front part 16b of the above-mentioned hinge pillar outer panel 16 are formed in the inside of pillar ff1P. That is, in this example, front part+6b of hinge pillar outer panel 16 corresponds to the partition member in a claim. And front part 16b of the above-mentioned hinge pillar outer panel 16 extends to the inside of side sill !, and these two closed sections 31.32 are the lower end portions of the front part 16b. It is in the state where did not stop at the upper portion but it was greatly expanded from the side sill 1 to the inside of the side sill 1 from the place which divides the inside of the side sill l (which namely, corresponds to the extendedly installed part in a claim) in the direction of body order. Front part 16b of hinge pillar outer panel 16 which extends to the inside of this side sill 1 in this case acts as a paragraph which divides the inside of pillar part P and side sill l in the direction of body order, respectively. In this example, in order to improve further the section performance of the above-mentioned pillar part P, the paragraph which stations five Gasset 21~25 in the pillar part P, and is prolonged in the direction of body order in that inside as shown in Drawing 2 is formed. Thus, the thing which two closed sections 31.32 prolonged in the direction of body order are formed in the inside of pillar part P, and is done for the expansion installation of this closed section 31.32 to the inside of side sill 1, As compared with the case where the pillar part P is moreover formed only in an upper portion from side sill 1 in one closed section, the section performance [ as opposed to / bend and / power ] to the direction of body order of the pillar part P becomes high, and the rigid rise in the direction of body order of pillar part P will be achieved so much more effectively. It is front part+6b of hinge pillar outer panel 16 in this case, By straddling the side sill l side from the pillar part P side, it functions effectively as both the paragraph which divides the inside of pillar part P in the direction of body order, and a paragraph which divides the inside of the side sill l in the direction of body order, and contributes to the rigid rise of the bonding link of pillar part P and side sill l. As for such a rigid rise effect, it is needless to say that it is obtained also by the paragraph effect of each above-mentioned Gusset 21~25 which is not depended only on the paragraph effect of front part 16b of hinge pillar outer panel 16, and has been arranged in the pillar part P. the paragraph effect according [ on the thing of this example, and ] to front part 16b of each of these Gusset 21~25 and hinge pillar outer panel 16, etc. -- effective -- it should use As shown in Drawing 2, fitting part 35.36 of door hinge 37*38 is faced providing on Cowl side panel 4, respectively, He makes the formation position of the door hinge fitting part 35.36 correspond to the portion surrounded by front part 16b of above-mentioned hinge pillar outer Penel 16, and Gasset 21.22, and is trying to aim at the rise of the support rigidity of the door hinge 37*38. moreover -- while attaching approximately triangle-like corner bracket 2G to the corner part of the front frame 8 and pillar part P in this example in order to secure the joint rigidity between front frame 8 and pillar part P as shown in Drawings 2 and 4 He makes the edge by the side of pillar part P of the corner bracket 26 correspond to three Gasset 21.23.25 in the pillar part P, and is trying to receive the load concerning the corner bracket 26 by the whole pillar part P via this each Gusset 21 and 23.25.
