Each permanent magnet provided in a rotor includes a projection that projects toward a corresponding predetermined portion of the rotor core. An inner peripheral surface of each permanent magnet, which is radially opposed to the corresponding predetermined portion of the rotor core, includes a primary contacting portion and two primary non-contacting portions. The primary contacting portion contacts the corresponding predetermined portion of the rotor core at a circumferential location, which corresponds to the projection. The primary non-contacting portions do not contact the rotor core and are located on two circumferentially opposite sides, respectively, of the primary contacting portion. |
