PROBLEM TO BE SOLVED: To provide a rotor for a rotary electric machine and a rotor for a magnet type AC generator which can sufficiently reduce an unbalance amount. SOLUTION: The magnet type AC generator 100 is so composed that a permanent magnet 34 is arranged to the outer periphery and power is generated by inducing an electromotive force to a stator 2 with the rotational magnetic field generated by the rotation. The rotor 3 is provided with a through-hole forming member 32 which is provided to the rotational center side of the permanent magnet 34 to which a through-hole 32A is formed, and has a balance adjusting screw hole 32B for reducing an unbalance amount during the rotation, and a rotary shaft 40 which is penetrated into the through-hole 32A of the through-hole forming member 32. The rotary shaft 40 has a spigot-joint part 42 fitted to a part of the through-hole 32A and a knurling part 44 press-fitted to the remaining part of the through-hole 32A. COPYRIGHT: (C)2005,JPO&NCIPI
