Abstract

A motor-driven remote control mirror device comprising: a mirror body (22) supporting a mirror (21), and a forwardly and backwardly movable rod (56) adapted to be contact with the back surface of the mirror body (22) for inclining the mirror body (22) around horizontal and vertical axes thereof; the center of a pivot (55) formed at the end of the rod (56) and in contact with the mirror body (22) being arranged at a position which is displaced Δl from the center axis (l₁) of the shaft portion (57) of the rod (56) so that the rod (56) is prevented from being rotated around the axis of the shaft portion (57) of the rod (56), thereby image fluctuation due to minute vibrations can be prevented when inclining the mirror surface.

Claims

1. A motor-driven remote-control mirror device, comprising:

a mirror body (22) supporting a mirror (21) and which is supported itself for angular movement within a mirror shell (23);

electric motors (5) as drive for said mirror (21), which are fixed within said mirror shell (23); and

means to convert the rotation of the motor (50) to linear motion and to convey it to the mirror body (22), said means being comprised of a gear mechanism (53) mechanically coupled with said motor (50);

a shaft (57) fixed to said gear mechanism (53) and provided with a spiral recess in which a hair pin-shaped spring (62) is engaged; and

a pivot (55) formed as extended from one end of said shaft (57) and fitted in a seat (54) formed on the rear surface of said mirror body (22);

said pivot being disposed with the center thereof not coincident with the axis of said shaft (57), so that said shaft (57) is prevented from being rotated around the axis thereof.
