Abstract

A drive device comprises an electric drive motor (1) and a reduction gear (2), such as a worm gear, which is connected to the motor to form a structural unit. The drive element (16) on the input side of the reduction gear is mounted on an extended shaft portion of the motor. Three bearings (11, 12, 20) journal both ends of the shaft (10) and an intermediate position between the motor armature (8) and the drive element (16). One of the bearings located at the end of the shaft is in the form of a self-centering bearing (20) which is clamped to the housing of the drive device in a position in alignment with the other two bearings (11 and 12). <IMAGE>
