<p>PROBLEM TO BE SOLVED: To provide a press-fit fixing structure capable of reducing a peak of a press-fit load at an initial stage of press-fitting when a laminate core is fixed by being press-fitted into another member.SOLUTION: An outer peripheral surface 12a of a stator core 12 has a plurality of core projections 25 which are intermittently formed in a circumferential direction. An inner peripheral surface 13a of a stator holder 13 has a plurality of holder projections 27 which are intermittently formed in a laminating direction (an axial direction) of a plurality of steel plates 18. When the outer peripheral surface 12a of the stator core 12 is press-fitted into the inner peripheral surface 13a of the stator holder 13, the core projections 25 get in an inner side of the inner peripheral surface 13a of the stator holder 13 by plastically deforming the holder projections 27. Among the plurality of holder projections 27, a holder projection 27 disposed at a laminating direction end 29 has a radial height B1 that is made lower than a radial height B of the other holder projections 27.</p> |
