    Patent number: 5126608
    Abstract: A motor housing structure with an integrally molded electric connector comprises a front flange (26) and a molded rear housing (28) fixed respectively to the front and rear ends of the core (12) of the stator (10) of a motor, and supports a rotor (20) for rotation in rotary bearings (30, 32) held respectively on the front flange (26) and the molded rear housing (28) with a gap between the inner circumference of the stator (10) and the outer circumference of the rotor (20). The front flange (26) is formed of a metal and the rear housing (28) is formed as a lightweight resin member, by molding. An electric connector unit (40), to which an external electric connector (50) is connected to supply electric drive current to the motor, is formed integrally with the molded rear housing (28). The external electric connector (50) is plugged into the electric connector unit (40) in a direction along the axis of the motor, to electrically connect the external electric connector (50) to the electric connector unit (40).
