Abstract
In a window lifter drive for motor vehicles a base member contains a cable drum to which a manual crank handle drive or a motor drive can be selectively secured. The base member includes a housing enclosing the cable driven with an opening on one side for a pinion on the crank handle drive. The housing has an opening on the opposite side for a driving claw part of the motor drive. Each of the pinion and the driving claw part can act directly on the cable drum.
