ABSTRACT:
A retracting mechanism for storing or erecting a mirror includes, at a coupled portion of an output shaft of a drive motor and a worm gear, coupling retaining portions fitted together in a press-fitted state and rotational force transmitting portions opposing each other in a state where a predetermined gap is present between them. The coupling retaining portions are configured by a circular shaft portion and a circular fitting hole, and the rotational force transmitting portions are configured by a double D-cut portion and double D-protruding portions. The rotational force of the output shaft is transmitted by the rotational force transmitting portions, and the coupled state of the output shaft and the worm gear is retained on the same axial line and the slanting of the worm gear is prevented by the coupling retaining portions.
