Abstract

A rotor for a rotating electric machine includes a rotor core provided with a pair of first magnets and a pair of second magnets that are located closer than the first magnets to an outer peripheral side of the rotor core. The rotor core includes a caulking portion disposed in a region between first and second imaginary lines in a radial direction of the rotor core. The first imaginary line is an arc passing through outer-peripheral-side end portions of respective long sides of rectangular-shaped cross sections of the first magnets. The second imaginary line is an arc passing through inner-peripheral-side end portions of respective long sides of rectangular-shaped cross sections of the second magnets. The arc of each of the first and second imaginary lines has a center of curvature that lies at an intersection of extensions of the long sides of the rectangular-shaped cross sections of the second magnets.
