Abstract: A rotor of a rotary electric machine includes a rotor shaft serving as a rotation axis, an annular rotor core having a first hole at center in which rotor shaft is disposed, and magnet disposed in circumferential direction of the rotor core and provided for each magnetic pole. Rotor core includes plurality of second holes provided in circumferential direction and in which magnet is disposed, and plurality of third holes provided in circumferential direction and located radially inward with respect to second holes. Third hole includes outer and inner sidewall portions located radially inward with respect to outer sidewall portion, and a pair of sidewall portions provided on both sides of outer and inner sidewall portions and connecting the outer and inner sidewall portions. Inner sidewall portion has a distance changing portion whose distance from a rotation center of rotation axis changes. Inner sidewall portion does not protrude radially inward.

Abstract: A rotor for a rotary electric machine includes: a rotor core having an annular shape when viewed in an axial direction; a rotor shaft disposed on a radially inner side of the rotor core and coupled to the rotor core by an interference in a radial direction; and a magnet disposed in the rotor core for each magnetic pole in a form in which a plurality of magnetic poles are formed along a circumferential direction.
