ABSTRACT:
A stator core is fixed to a housing by pressing an axial end portion thereof in an axial direction by a flange or a washer of a bolt. An intermediate member, which is softer than the flange or the washer of the bolt, is provided at a contact portion between the flange or the washer and the axial end portion of the stator core. The stator core may have a cavity to directly receive the flange or washer of the bolt in place of the intermediate member.
