The outputting member fits onto the rotor, and the rotor has at least one of a recess portion and a projection portion at a fitting surface of the rotor. The outputting member is jointed with the rotor so as to have a shape corresponding to the at least one of the recess portion and the projection portion by welding. | 10-02-2008 |
