Rotor of rotary electric machine

A rotor of a rotary electric machine comprising:

• a rotor iron core including a plurality of magnetic poles lined up in a circumferential direction around a central axis, a plurality of magnet holding slots arranged at intervals in the circumferential direction for each of these magnetic poles, an outer peripheral side iron core portion located between each of the magnet holding slots in the circumferential direction for each of the magnetic poles, an inner peripheral side iron core portion located between each of the magnet holding slots and the central axis for each of the magnet poles, a plurality of bridges passed between the outer peripheral side iron core portion and the inner peripheral side iron core portion at a location between each of the magnet holding slots for each of the magnetic poles, and a plurality of magnet holding protrusions extending from a middle portion of each of the bridges to each of the magnet holding slots in each of the magnetic poles;
• and
• a plurality of permanent magnets that is accommodated in each of the magnet holding slots and in contact with each of the magnet holding protrusions.
