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).Field of SearchMolded plasticConnectors, terminals or lead-ins Housings, windows or covers Impregnated material Crimped end terminal Encompassing wire Coupling part having concentric contacts Having push-pull-engaging contacts spaced along planar side wall transverse to longitudinal engagement axis (e.g., telephone jack or plug) Having modular or multipart insulating body WITHIN MACHINE CASING OR MOTOR HOUSING (CONNECTOR WITHIN CASING WALL) | |
