Apparatus for the limitation of the wiping angle of a windscreen wiper

The present invention relates to a drive unit, in particular for a windshield wiper system on a motor vehicle, comprising a drive motor, a gearing accommodated in a gear housing and following the drive motor, which gearing has an output shaft driven in pendulum fashion and a pinion seated on it in a manner protected against twisting as well as including a stop member for limiting the pendulum angle of the output shaft. The stop member is either swivellable with the pinion or firmly arranged on the output shaft. In order to obtain a good guidance and a reliable hold of the stop member it is pushed upon the output shaft by means of a ring-shaped portion. In particular the ring-shaped portion can simultaneously serve as a buffer disc for the pinon, so that in comparison with a known drive unit, piece parts can be saved.
