Claim Text:
1. A press-fitting structure that fixes a laminated steel sheet forming a magnetic path to another member by means of press fitting, wherein a first projection and a first recess are formed in turn on a press-fitting face of the laminated steel sheet, the first projection and the first recess extending in substantially a press-fitting direction, a second projection and a second recess are formed in turn on a face to be press-fitted of said another member, the second projection and the second recess extending in a direction intersecting the press-fitting direction, in a state in which the first projection and the second projection have been put in contact with each other and press fitted, an amount of plastic deformation of the second projection is larger than an amount of plastic deformation of the first projection, and a pitch of the second projection is larger than a sheet thickness of a single sheet of the laminated steel sheet.
