Abstract
A rotor for a rotating electric machine includes a cylindrical rotor core, a housing hole extending through the rotor core in a direction of a center line of the rotor core, a permanent magnet that is fixed while being accommodated in the housing hole, and a fixing member made of a plastic that fills a gap between an inner surface of the housing hole and an outer surface of the permanent magnet. The permanent magnet is split into two segments such that division surfaces extend in the direction of the center line. The permanent magnet is disposed such that a distance between the two segments decreases from a first end to a second end of the segments in the direction of the center line.
