PURPOSE:To reduce the size and the weight of a door mirror structure and to prevent damage thereof, by a method wherein a reduction gear for driving a mirror housing is secured to a mirror base, and its output shaft is connected to the mirror housing through a transmission means having limiter function. CONSTITUTION:A mirror housing 1 has a bearing 1a which is rotatably supported in a manner to be engaged with a bracket 2a of a mirror base 2. A motor M and a reduction gear coupled directly to the motor are concentrically secured to a shaft 5 positioned in juxtaposition with the bracket 2a. Namely, the reduction gear T is secured to the mirror base 2 through a mounting plate 9 in a manner that the shaft 5, the bearing 1a, and an output shaft 8 of the reduction gear T are positioned on the same axis. The output shaft 8 is connected to the mirror housing 1. For example, a clutch plate 10, a pressure plate 11, and a clutch spring 12 are mounted to a spline 8a of the output shaft 8, and a passive plate 16 is pressed between the nip formed therebetween through a clutch lining 15. |
