The stator includes a tube-shaped stator core () having a ring-shaped second contact surface (S;S) that is opposite of the first contact surface, and coils () wound on the stator core. The stator is held by the motor housing with the first contact surface in contact with the bottom part. A protruding part (S;S) of the baffle plate contacts the entire circumference of the second contact surface of the stator core and is fixed to the motor housing by three or more screws ().
