Abstract

In general, according to an embodiment, in a cross section of a rotator iron core vertical to a rotation center, a second edge is positioned on a more outer side than a first edge in a radial direction of a rotator iron core. An outer-peripheral central engaging projection is formed in a part of the second edge that is most convex toward a rotation center. An inner-peripheral engaging projection is formed in the vicinity of each of both end portions of the first edge. A magnet can be fixed between the outer-peripheral central engaging projection and one of the inner - peripheral engaging projections and a magnet can be fixed between the outer-peripheral central engaging projection and the other inner-peripheral engaging projection such that a cross section of the magnets vertical to the rotation center is line-symmetric to a straight line connecting the rotation center and the outer-peripheral central engaging projection.
