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.

Dependent claims

A retracting mechanism of a vehicular outer mirror device, the retracting mechanism comprising:

a case member that is pivotably supported on a support shaft of a vehicle body and to which a vehicular outer mirror is coupled;
a motor disposed in the case member;
a motor gear that is disposed in the case member, is coupled to an output shaft of the motor, and is rotated by the driving of the motor;
a gear plate attached to the support shaft such that its rotation with respect to the support shaft can be prevented;
and
intermediate gears that are disposed in the case member and mesh with the motor gear and the gear plate to couple the motor gear and the gear plate together, with the intermediate gears rotating while meshing the periphery of the gear plate in a state where the rotation of the gear plate with respect to the support shaft is prevented, whereby the outer mirror is pivoted together with the case member around the support shaft,
wherein the coupled portion of the output shaft of the motor and the motor gear includes
coupling retaining portions that are fitted together in a press-fitted state, retain the coupled state of the output shaft of the motor and the motor gear on the same axial line, and deter the slanting of the motor gear, and
rotational force transmitting portions that oppose each other in a state where a predetermined gap is present between the output shaft of the motor and the motor gear, and transmit only the rotational force of the motor to the motor gear.
