A motor having a rotor in which a rotor magnet is fixed on the outer peripheral surface of a rotor body. The motor is configured so that the support shaft portion is formed of a material having a self-lubricating property, and a first sliding surface of the support shaft portion is supported rotatably. Also, the motor is configured so as to have a metallic motor casing, a rotor provided in the motor casing to drive a motor shaft projecting from the motor casing through a shaft hole in an end wall portion, a stator provided around the rotor in the motor casing to rotationally drive the rotor, a cover member provided to close the other end opening of the motor casing, and a connector body integrally formed of a resin so as to seal the other end opening of the motor casing from the outside of the cover member.
