In accordance with this invention the catch plate is designed as a single-piece plastic injection molding mounted onto the output shaft, with a first bearing bushing to mount the output shaft in the gear housing and a second bearing bushing mounted concentrically to the first bearing bushing to mount the worm wheel on the catch plate.
