A press-fitting structure has a press-fitting, face of a rotor yoke formed from a laminated. steel sheet is press fitted onto a face to be press-fitted of a rotor shaft, fitting is carried out with plastic deformation while the first projection of a press-fitting face of a rotor yoke, on which a first projection and a first recess extending in substantially the press-fitting direction are formed in turn, and the second projection of the face to be press-fitted of the rotor shaft, on which a second. projection and a second recess extending in the direction intersecting the press-fitting direction are formed in turn, are in contact with each other. Since in a state in which press fitting is completed, the amount of plastic deformation of the second projection of the rotor shaft is larger than the amount of plastic deformation of the first projection of the rotor yoke. |
