Abstract
A rotor includes a rotor core formed by rotationally stacking multiple iron core pieces or multiple blocks. The rotor core includes multiple magnet housing holes. A magnet is accommodated in each of the magnet housing holes. A portion of the rotor core between each magnet housing hole and an outer circumferential surface of the rotor core located on a radially outer side of the magnet housing hole is defined as a designated region. Some of the designated regions include at least one first designated region including a different-shape portion different in shape or position from those in the other designated regions. In the multiple iron core pieces or in the multiple blocks, the first designated region and one of the designated regions that does not include the different-shape portion overlap in an axial direction of the rotor.
