Abstract
A device for driving a rope-like power transmission member for a window lifting mechanism, such as in a motor vehicle, includes a casing with a worm rotatably supported within the casing, a worm gear in the casing and in engagement with the worm and an electric motor driving the worm. A rope drum is positioned within the casing and a coupling part interconnects the drum and the worm gear. The casing has an opening for moving the rope out of the casing. A sealing plate is located between the worm gear and the coupling part and divides the interior of the casing into a first partial space containing the worm and worm gear and a second partial space containing the drum and the coupling part. The sealing plate is arranged in form-locking engagement with the worm gear and it has an annular area facing toward the drum which is in contact with an annular area on the inner surface of the casing.
