1. A drive apparatus for adjustment devices of motor vehicles, comprising:
an at least two-part housing (1) having a cover element (6) with a flat first surface and a flat second surface opposite the first surface, and a receptacle element (7), wherein an electric drive unit (2) and an operatively connected gear unit (3) are arranged in the receptacle element (7), wherein the receptacle element (7) of the housing (1) is configured as part of the gear unit (3) with a one-piece continuous cylindrical wall with an inner surface that defines an opening to receive a drive shaft (13) of the drive unit (2) said drive shaft (13) having a length and defining an axis along the length, wherein internal teeth (40) are arranged on the inner surface of the cylindrical wall of the receptacle element (7) that are configured to intermesh with external teeth (5) of a part of the gear unit (3), and wherein the cover element (6) and the receptacle element (7) are arranged in a line disposed in a same direction as the drive shaft axis or in a line disposed parallel to the drive shaft axis; and
a control unit (11) for the drive unit (2), wherein the control unit is arranged on a printed circuit board (12) configured as a printed circuit with integrated circuits or with switching circuitry, and wherein the printed circuit board (12) is arranged inside the housing (1) parallel to the drive shaft (13) of the drive unit (2);
wherein the housing (1) is closed by the cover element (6) to retain the printed circuit board (12) inside the housing (1).
