Abstract
The invention relates to a drive device for a vehicle rearview mirror, the positioning of which is achieved by means of a worm gear mounted by means of a coupling part in a single bearing, which is provided with an annular collar that engages in an upper annular slot of the coupling part. The intention is to improve the retaining force of the bearing. This is achieved according to the invention by providing that a cylindrical region provided with an upper and a lower guide surface adjoins the upper annular slot, the wall of the bearing surrounding the cylindrical region of the coupling part being disposed at a distance from the coupling part and guide surfaces corresponding to the guide surfaces of the coupling part being formed in the bearing, that the inside diameter of the annular collar is slightly smaller than the outside diameter of the cylindrical region of the coupling part, and that the angle that the inner face of the annular collar forms with the cross-sectional plane of the coupling part is in the range between 30.degree. and 60.degree..
