Abstract
Abstract A remote control side mirror device for a vehicle capable of rotating a mirror housing with respect to a mirror base fixed to an automotive body by a motor driven remote control. The motor driven by a remote control is fixed in the mirror housing to rotate a first gear through a reduction gear. A support shaft for rotatably supporting the mirror housing vertically is formed at the mirror base, and a second gear engaged in mesh with a first gear is arranged at the mirror housing side of the support shaft. Since the second gear is stationarily connected by the frictional force to the support shaft through a friction transmitting mechanism. When the motor is driven, the mirror housing is rotated around the support shaft of the mirror base. When the mirror housing receives a strong external force, the second gear can slide around the support shaft to prevent the reduction gear from damaging.
