Abstract: A rear frame has a fastening portion, which radially extends from an outer peripheral surface of the rear frame and receives a fastening force of a through bolt. A circuit board, which includes a control circuit, is installed to an axially outer surface of a main body of the rear frame. A reinforcing portion is provided in the fastening portion to limit deformation of the main body of the rear frame, which is induced by the fastening force of the through bolt.

Abstract: A drive apparatus includes a motor unit and an electronic control unit. The motor unit includes a first end frame, a second end frame, a stator, a rotor and a shaft. The control unit controls driving of the shaft. An outer wall surface of the stator is exposed between the first end frame and the second end frame. The stator is thus enabled to contact outside air directly so that heat radiation characteristic of the stator is improved.
