Rotor, rotary electric machine, method of manufacturing rotor, and rotor manufacturing apparatus

A rotor comprising:

• a rotor core unit having a rotor core fixed to a rotation axis so as to be able to rotate integrally therewith and a plurality of permanent magnets mounted on the rotor core along a circumferential direction thereof;
• and
• a single cylindrical rotor cover having a first holding portion and a second holding portion so as to cover an outer circumference of the rotor core, the first holding portion being in contact with an outer circumferential edge portion positioned on one end surface in an axial direction of the permanent magnet, the second holding portion being in contact with at least one of another end surface of the permanent magnet and the rotor core so that the rotor core unit is held in the axial direction by the first holding portion and the second holding portion wherein
• the rotor core has a protruding portion protruding further in the axial direction than the another end surface of the permanent magnet, and
• a bottom portion of the rotor cover facing the another end surface of the permanent magnet is provided with a recessed portion formed so that an inner side in the axial direction of the rotor cover is recessed along an outer circumferential edge portion of the protruding portion, the recessed portion being in contact with the outer circumferential edge portion of the protruding portion.
