Claims

[Scope of utility model registration request]

The mirror housing includes a base having a cylindrical bearing part and attached to the door, a mirror housing rotatably fitted to the outer periphery of the bearing part so as to be prevented from moving vertically, and a reduction gear mechanism. a mirror storage drive motor disposed within the mirror housing;
A first clutch is inserted between the bearing surfaces of the base and the mirror housing, and the first clutch is inserted into the bearing part so as to be vertically movable and rotatable, and the rotation of the drive motor is transmitted through the reduction gear mechanism. a second clutch comprising a pair of cam members provided on the shaft and the bearing portion respectively and having a convex portion and a concave portion engaging with each other on opposing surfaces and having a larger meshing force than the first clutch; and a spring that urges the shaft downward so that the second clutch engages.
