Abstract

A motor includes a rotor, a stator having coils, a connector for supplying electrical power to the coils, and a resin sealing member. The resin sealing member comprises an opposite-to-output side sealing part and a connector sealing part covering the connector. The connector comprises a frame part into which the cable side connector is to be inserted, and the opposite-to-output side sealing part comprises a first protruded part and a second protruded part. A tip end face of the first protruded part and a tip end face of the second protruded part are located on one imaginary face intersecting the rotation center line, a tip end on the opposite-to-output side of the frame part is located on the output side with respect to the imaginary face, and the second protruded part is provided at a position closer to the frame part between the first protruded part and the frame part.
