ROTOR OF ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To prevent components attached to a rotor of a rotary electric machine from scattering.SOLUTION: A coil 26 is arranged in a slot of a rotor core 18 of a rotor 10. Gaps in the slot are filled with resin 30. An end plate 36 is arranged at each of both outward side ends in a rotor axis direction of the rotor core 18. A circumferential groove 42 is formed in an outer peripheral surface 40 of the end plate. A common columnar side face is formed of an outer peripheral surface 34 of a coil member 32 including the coil 26 and the resin 30, an apical surface of the magnetic pole of the rotor core 18, and the outer peripheral surface 40 of the end plate. A steel wire 44 is spirally wound along the columnar side face from one end to the other end of the rotor 10. The steel wire 44 is wound in the circumferential groove 42 in an overlapping manner.
