A rotor includes a rotor core that has magnet-receiving holes in each of which is received a corresponding permanent magnet. The rotor core also has, for each of the magnet-receiving holes, first and second supporting portions. The first supporting portion supports a radially inner end portion of a first magnetic flux barrier-side face of the corresponding permanent magnet. The second supporting portion supports a radially outer end portion of a second magnetic flux barrier-side face of the corresponding permanent magnet. A second magnetic flux barrier-side end portion of a radially outer wall surface of the magnet-receiving hole is planar in shape and parallel to a radially outer side face of the corresponding permanent magnet. A second magnetic flux barrier-side end portion of a radially inner wall surface of the magnet-receiving hole is planar in shape and parallel to a radially inner side face of the corresponding permanent magnet. |
