A rotor of a rotary electric machine for a vehicle includes a rotor shaft and a rotor core including a plurality of electromagnetic steel plates fitted to an outer peripheral surface of a rotor shaft in an interference fit state or a transition fit state. A strength of the electromagnetic steel plate disposed in at least one of end portions of the rotor core in an axial direction of the rotor shaft is set to be higher than a strength of the electromagnetic steel plate disposed in a central portion of the rotor core in the axial direction of the rotor shaft.
