Claim 0:
1. A rotor comprising:
a rotor core in which a shaft through-hole and a magnet insertion hole that form a plurality of layers in a radial direction toward a central axis of the shaft through-hole are formed;
a magnet press-fitted into the magnet insertion hole, and
a compression part configured to apply a load to the rotor core from an outward side in the radial direction toward an inward side in the radial direction,
wherein the rotor core includes a reinforcement part between the shaft throughhole and a first magnet insertion hole disposed on outermost side in the radial direction,
wherein, among the magnet insertion hole comprising the plurality of layers, a pair of second magnet insertion holes located on an inward side of the first magnet insertion hole in the radial direction are arranged in a circumferential direction to sandwich a center rib extending in the radial direction,
wherein the reinforcement part includes the center rib, and
wherein the reinforcement part includes a contact portion, with which the magnet comes into contact, when a load from the compression part is applied to the rotor core.
