An electric motor-and-gear assembly for driving vehicle aggregates such as windshield and rear window wipers, power-window units and the like, having a transmission housing that can be closed by a housing cover. A motor housing that contains a commutator motor whose commutator protrudes into the transmission housing and cooperates with a brush holder fixed in the transmission housing. For the sake of a more reasonably priced manufacture and a time-saving, more rapid assembly of the brush holder, the commutator brushes are embodied as hammer brushes with spring leaf actuators prestressed toward the commutator. The spring leaf actuator are respectively fixed with their one actuator end in a U-shaped plastic carrying part of the brush holder, which is inserted into the transmission housing radial to the commutator, through the housing opening and is positioned in the transmission housing in a positively engaging manner by means of the housing cover.
