ABSTRACT:
An assembly, specifically a mirror assembly for a motor vehicle, in part angularly adjustable by an electric motor and drive mechanism. A fixed motor drives a worm that is angularly movable through a flexible coupling into selective engagement with one of two nuts to drive adjusting screws that cause a mirror element to pivot about one of two mutually perpendicular axes. The screws and pivot structure for the mirror are integrally formed as part of a mirror supporting plate. The nuts are yieldably coupled to the threads of the adjusting screws to permit slippage between the two when forces exceed the wormed driving force. Operating noise is reduce by a vibration-damping motor mounting and by structure limiting worm engagement with the nuts. Projections are carried by the mirror supporting plate resiliently biased against a fixed support to reduce vibration.
