車両用バックミラー装置

Rear view mirror device for vehicle

Abstract

PROBLEM TO BE SOLVED: To make it possible to adjust an angle by tilting a mirror up-and-down and right-to-left at the same time by selecting a tilt axis of mirror on a straight line passing the center of a mirror holding portion and driving a push-pull member foreword or backward with drive means. SOLUTION: A mirror holder 16 for holding a mirror 12 has a semi-spherical shaft portion as a linking portion projecting out to the rear side and this semi- spherical shaft portion 18 is supported by an actuator 14. Also, at the rear side of the mirror holder 16, a spherical bearing 24 is put in a recessed space in one united body in a state of opening into the rear side at a position outside a center portion, the mirror 16 is pushed and pulled by the actuator 14, and the mirror 12 can be tilted around the semi-spherical shaft portion 18. The actuator 14 comprises a case 26, a DC motor 28 as drive means, a reduction mechanism 30, a push-pull member 32, and frictional resistance adjusting means 34 as means for restricting the tilt.
