Small vehicle

0001The present invention relates to a small vehicle including a main seat for a rider and a rear seat disposed behind the main seat for allowing a fellow passenger to sit thereon on a rear portion of a vehicle body cover, and the vehicle cover including a storage space extending at least from the front end of the main seat to the rear end of the rear seat formed in the vehicle body cover below the main seat and the rear seat.

0002In such type of small vehicle, for example, in a scooter type motorcycle, a main seat and a rear seat for covering an upper end opening of a storage space is mounted to the rear portion of the vehicle body cover so as to be capable of being opened and closed.

0003Document JP-A- 2001- 10572 discloses a small vehicle according to the preamble of claim 1.

0004However, in the small vehicle constituted as described above, since a power unit is disposed downwardly of the main seat and the rear seat, a space formed by the main seat and the rear seat in a state in which the upper end opening of the storage space is closed with respect to the power unit is partly small, and thus the storage space is obliged to be partly reduced in size. Therefore, although the storage space is relatively elongated in the fore-and-aft direction of the small vehicle, an elongated object, such as a golf bag cannot be stored in the storage space.

0005In view of such circumstances, it is an object of the present invention to provide a small vehicle having high storability by enabling storage of an elongated object in a storage space.

0006In order to achieve the object described above, the present invention provides a small vehicle including a main seat for a rider and a rear seat arranged behind the main seat for allowing a fellow passenger to sit thereon disposed on the rear portion of a vehicle body cover, and a storage space is formed so as to extend at least from the front end of the main seat to the rear end of the rear seat formed in the vehicle body cover below the main seat and the rear seat, characterized in that a lid member, which has an opening in the portion corresponding at least to one of the main seat and the rear seat and supports the main seat and the rear seat, is mounted to the rear portion of the vehicle body cover so as to openably cover the upper end opening of the storage space, a variable shape closing member formed of a deformable material for closing the opening is mounted to the lid member, and at least one of the main seat and the rear seat corresponding to the opening is mounted to the lid member via a supporting member which can be adjusted in height from the lid member.

0007In this arrangement, the opening formed on the lid member for covering the upper end opening of the storage space is closed by the variable shape closing member, and at least one of the main seat and the rear seat corresponding to the opening can be mounted to the lid member so as to be capable of being adjusted in height. Therefore, when the height of the seat is heightened, it is possible to deform the variable shape closing member in the space between the seat and the lid member. Consequently, when an object, which might project from the opening of the lid member when the lid member is closed, is stored in the storage space, the upper end opening of the storage space may be closed by the lid member and the variable shape closing member while deforming the variable shape closing member, and thus the elongated object can be stored in the storage space using the storage space of the small vehicle, which is elongated in the fore-and-aft direction, effectively from the front end to the rear end thereof, so that the storability is improved. In addition, even when the object to be stored, which may deform the variable shape closing member, is not stored in the storage space, the height of the seat may be adjusted according to the physical constitution of at least one of the rider and the fellow passenger by adjusting the height of at least one of the main seat and the rear seat.

0008As described thus far, according to the present invention, even when an object to be stored, which might be projected upward from the opening of the lid member when the lid member is closed, is stored in the storage space, the upper end opening of the storage space may be closed by the lid member and the variable shape closing member while deforming the variable shape closing member, and thus the elongated object may be stored in the storage space that is elongated in the fore-and-aft direction of the small vehicle by utilizing the space effectively from the front end to the rear end, whereby storability may be improved. In addition, by adjusting the height of at least one of the main seat and the rear seat, the height of the seat can be adjusted according to the physical constitution of at least one of the rider and the fellow passenger.

0009An embodiment of the present invention will be described based on an example of the present invention shown in attached drawings.
