Abstract
In a motor-gear drive unit, particularly for automobile window lifters and the like, a moisture-tight closure of the gear case (2) is provided by a gear case cover (4). The cover (4) is preferably injection-molded from plastic and can be connected to the gear case (2) nonpositively by a press-fitted, insertable clamp fastening. Specifically, the clamp fastening takes the form of a peripheral web (4.1) capable of being pressed into a peripheral channel-like groove (2.2), where the peripheral web (4.1) and the peripheral channel-like groove (2.2) are provided, respectively, on either the case (2) or the cover (4). If the peripheral web (4.1) is provided on the cover (4), a peripheral scraping rib (4.11) is molded on the inside surface of the web (4.1). An elastic gasket layer (5) having a static sealing edge (5.1) is applied, e.g., injection-molded onto an outer surface of the peripheral web (4.1).
