ROTOR FOR ROTATING ELECTRICAL MACHINE

According to an embodiment, a rotor of a rotary electric machine, includes a rotational shaft 30, a rotator core 32 coaxially fixed to the rotational shaft, a plurality of rotor bars 60 each inserted through a slot 50 of the rotor core, and including a first bar end 40a extending from a first end surface 32a of the rotor core in the axial direction and a second bar end extending from a second end surface of the rotor core in the axial direction, a first annular end ring 42a fixed to extending ends of the first bar ends, and a second annular end ring fixed to extending ends of the second bar ends. Each of the rotor bars includes a swage groove 61 extending in the axial direction to be opposed to an opening, and a first end swage groove 61a formed in the first bar end continuously to the swage groove, and the first end swage groove extends from the position of the first end surface 32a toward the first end ring with being inclined to an outside in a radial direction of the rotator core.
