ABSTRACT:
A device for driving of sliding roofs, window raisers, or the like, especially of motor vehicles, with a reversible drive motor (1) and a worm gear pair on an output side of the drive motor, with a shaft of a worm gear (2) forming an extension of the motor shaft. The axial play of the worm gear shaft (2) is adjustable by an adjustment part (4) which rests against a distal end of the worm gear shaft (2) and which is movably guided in an axial direction of the worm gear shaft (2). The adjustment part (4) can be pressed against a stationary guide surface (17) by a positioning screw (12) which is screwed into an opening of this guide surface (17) or by a fastening rivet (22) which penetrates a hole (23) in the guide surface. The longitudinal axis of the screw (12) or rivet (22) is at least approximately perpendicular to the worm gear shaft axis (9).
