A frame of an electric motor opens in one end. A heat sink, to which a control substrate is connected, closes an opening of the frame. A stator is positioned on an inner circumferential surface of the frame to be movable in an axis of rotation direction. A fastening bolt penetrates through the heat sink and a motor cover to fasten to the frame, thereby holding the stator between a pressing portion formed on the heat sink and a stepped portion formed on the inner circumferential surface to fix the stator to the frame. A disc spring is interposed between a front bearing that retains a rotor shaft and a spring retainer formed in the heat sink, and the rotor shaft is biased in the axis of rotation direction by a biasing force from the disc spring.
