Electric drive, especially for motor vehicles

An electrical drive mechanism, in particular for motor vehicles, having a housing (10), having a commutator motor (14) disposed in the housing (10);

• this commutator motor (14) has a rotor shaft (17), a commutator (22), which is non-rotatably supported on the rotor shaft (17) and connected to an armature winding (21) that rotates along with the rotor shaft (17), and a brush holder (30) that is affixed in the housing (10), with commutator brushes (28) resting against the circumference of the commutator (22), and having a bearing (25) disposed in the vicinity of the commutator (22), which is comprised of a bearing bush (34) that encloses the rotor shaft (17) with rotary play, a bearing seat (35) that contains the bearing bush (34) and has support surfaces for axially supporting the bearing bush (34), and a clamping member (37) that clamps the bearing bush (34) in the bearing seat (35) against the support surfaces in a frictionally engaged fashion, characterized in that the bearing seat (35) with support surfaces is formed directly into the housing (10) and the clamping member (37) is a one-piece component of the brush holder (30) that is preferably comprised of plastic.
