A bracket is disposed at an opening of a cylindrical bottomed frame. A stator with a stator winding is fixed to the frame around a rotor. Stator-side terminals each having a connection portion extending toward the bracket are disposed between the stator and the bracket, and are connected with the stator winding. A connector base includes connection terminals connected with tip ends of the connection portions, a base portion with the connection terminals disposed on a surface thereof, and nuts mounted on the base portion. Leads have, at their one end, lead-side terminals in contact with the connection terminals. Screws are threaded on the nuts, respectively, for coupling the connection terminals and the lead-side terminals.
