ABSTRACT:
A mirror angle adjusting device in remotely controlled rear-view mirror apparatus for automobile is arranged that: a supporting plate of the mirror is fixed to the ball of a ball-and-socket joint; a shaft extending from the ball is inserted in the through-hole defined by the two perpendicularly crossing elongated slots of two perpendicularly crossing slidable bars, and the device is operative so that the slidable bars are caused to make reciprocal movements by their mating motors to displace the position of the above-said through-hole, whereby the supporting plate of the mirror is inclined about the ball-and-socket joint. The rotation speeds of the motors are reduced by two sets of worm gears, and the speed-reduced rotations of the motors are converted to reciprocal motions by two sets of rack-and-pinion gears to cause the slidable bars to make the above-said reciprocal movements. Each of the worm wheels of the worm gears contains therein a slipping mechanism for preventing over-load operation of the motors.
