ABSTRACT:
An outside rearview mirror for vehicles having a fixed part and a folding part pivotally connected to each other. A reversible motor is mounted on the fixed part. A serrate shaft is commonly received in the pivot bosses of the parts, thus to pivotally couple the folding part to the fixed part. The rotational force of the motor is transmitted to the serrate shaft through power transmission means. The pivot boss of the folding part has an internal gear gearing into the serrate shaft, the internal gear coupling the second pivot boss to the serrate shaft in the spline type coupling. Both the rotating motion and the number of revolutions of the motor are controlled by motor control means. The power transmission means comprises a drive gear on the output shaft of the motor and speed reduction middle gears gearing into both the drive gear and the serrate shaft. The motor control means comprises an automatic/manual operation convert switch, a folding part closing/opening switch and a relay, a transfer contact relay, a folding part position detecting sensor and a limit switch part.
