ABSTRACT:
A support and drive unit for a mirror device having a housing and a mirrored mirror holder, includes a casing adapted to be disposed in the housing, a support structure adapted to pivotally support the mirrored mirror holder, and means for adjusting the mirror holder. The adjusting means comprises first and second actuating rods axially movably mounted on the casing, and a pair of motors disposed in the casing for moving the actuating rods, respectively, through coupling means. The actuating rods have front ends adapted to be pivotally coupled to the mirror holder, and are spaced substantially right-angularly from each other around the center of the support structure. One of the motors is disposed in an area defined between a side of a plane lying through the center of the support structure and a central axis of the first actuating rod and in which the second actuating rod is located, and a side of a plane lying through the center of the support structure and a central axis of the second actuating rod and in which the first actuating rod is located, said one of the motors having a shaft with a distal end thereof directed toward the support structure. The support and drive unit has a sufficient strength, vibration-resistant capability, and water resistance, and can be manufactured in a compact size.
