摘要：
A rotor of the present invention comprises a cylindrically shaped rotor core, and a plurality of magnets arranged at predetermined intervals at an outer circumferential surface of the rotor core. The outer circumferential surface of the rotor core is formed with a plurality of projections for positioning the plurality of magnets in the circumferential direction, and each of the projections extends over only part of outer circumferential surface of the rotor core in the height direction. The rotor core includes a projection-equipped cylindrical part which has an outer circumferential surface over which the plurality of projections extend, and a projection-less cylindrical part which has an outer circumferential surface over which the plurality of projections do not extend.
