PROBLEM TO BE SOLVED: To provide a rotor at low cost, of which adhesive is resistant to peeling, and a segment-shaped magnet is not deviated or peeled off easily even in case that the adhesive is degraded. SOLUTION: This rotor is previously formed with a rail-shaped part 15 integrally comprised of a wedge part pressing down the outer-periphery edge of the segment-shaped magnet 13 formed by decreasing the thickness of the outer- periphery edge in the circumferential direction to a roughly tapered state, and a fitting part fitted onto the inner wall of a groove part 14 formed at a cylindrical yoke 12 in the axial direction. The rail-shape part 15 is attached by conducting slide-fitting from the axial direction of the yoke 12. It is thus possible to complement the adhesion of the adhesive with a small number of components, thereby strengthening resistance against peeling in the direction of the centrifugal force of the segment-shaped magnet.
