Abstract
A front iron core includes a first iron core main body and a plurality of first projecting sections which project to a radial outer side from the first iron core main body. A second iron core includes a second iron core main body which overlaps with the first iron core main body and a plurality of second projecting sections which project to a radial outer side from the second iron core main body. When a rotor iron core is viewed along the axis line, portions of the second projecting sections protrude as extension sections to outward in the circumferential direction, from the first projecting sections. Furthermore, when the rotor iron core is viewed along the axis line, radial-direction outer side end surfaces of the extension parts are smoothly continuous with radial-direction outer side end surfaces of the first projecting sections.
