<p>PROBLEM TO BE SOLVED: To provide a rotor improved in reliability of insulation between neighboring coils while securing reliability in a mechanical strength of a rectifier piece in the rotor in which a lead wire including a coil and a short-circuit line is locked to a hook of the rectifier piece.SOLUTION: A rotor 20 comprises a core 22 including a slot 22b; a rectifier 30 including rectifier pieces 25; and a lead wire 23 including a coil 23a wound around the slot 22b and a short-circuit line 23b connecting rectifier pieces 25 which should have an equal potential, with each other. In the rotor 20, the lead wire 23 is locked to a hook 26 formed in the rectifier piece 25, and the hook 26 is folded and electrically connected with the lead wire 23. The coil 23a is locked at a tip side of the hook 26, the short-circuit line 23b is locked at a root side of the hook 26, a chamfered portion 26a2 is formed in a corner portion 26a1 of a coil lock part 26a, and a corner portion 26b1 is formed in a short-circuit line lock part 26b.</p> |
