A rear view mirror assembly

This invention relates to a rear view mirror assembly which can break away, when more then a predetermined force is applied to a rear view mirror (25). The rear view mirror assembly includes a base member (30) and a first unit. The first unit includes a mounting member (14), a second socket member (40) and a support arm (15) on which the rear view mirror (25) is rotatably mounted. The mounting member (14) is mounted on the base member (30), and the mounting member (14) has a first ball portion (32). The support arm (15) has a first socket portion (351) on an outer surface thereof, and the first socket portion (351) is slidably mounted on the first ball portion (32) of the mounting member (33). The support arm (15) further includes a second ball portion (352) on an inner surface thereof, and the inner surface is slidably mounted on the second socket member (40). The first unit is supported on the base member (30) through a bolt (38) and a spring (9). When a force is applied to the rear view mirror (25), the support arm (15) can rotate on the mounting member (33) and the first unit can rotate on the base member (30).
