A rotor including a rotor core and magnetic pole parts provided therein is provided. Each magnetic pole part includes a fixed magnetic-force magnet of which a magnetizing direction is oriented in a radial direction, first variable magnetic-force magnets disposed radially outward of the fixed magnetic-force magnet on both sides thereof in a circumferential direction so that magnetizing directions are oriented in the circumferential direction, a first cavity part formed in the rotor core to extend between a position radially inward of the fixed magnetic-force magnet and a position radially inward of the first variable magnetic-force magnet, and a second cavity part formed in the rotor core to be separated radially outward from the first cavity part, and extend toward the first variable magnetic-force magnet in the circumferential direction from a position radially outward of a surface on a first variable magnetic-force magnet side of the fixed magnetic-force magnet side.
