A rotor has plural reinforcing bodies each approximately formed in a U-shape having wing portions arranged in both side portions of an attaching portion of a flat plate shape, and disposed such that the attaching portion faces to each of inner circumferential wall surfaces of claw-shaped magnetic poles and the wing portions are located on both sides of the claw-shaped magnetic poles in the circumferential direction; and plural magnets each fixedly attached to both wing portions of each of the reinforcing bodies and disposed on both sides of the claw-shaped magnetic poles in the circumferential direction, for reducing leaked magnetic flux between the claw-shaped magnetic poles adjacent to each other, wherein a multidegree of freedom vibrating system composed of the claw-shaped magnetic poles and the reinforcing bodies fixedly attaching the magnets thereto is constructed by attaching each of the reinforcing bodies in a state in which at least one portion of the attaching portion is fixedly attached to the inner circumferential wall surfaces of each of the claw-shaped magnetic poles.
