PURPOSE:To enable the mass production of a rotary electric machine and to prevent the removal of a balance piece by axially protruding a cylinder having a collar from an iron core retainer on the end face of a rotor and mounting the balance piece via a mounting member having elasticity at the collar. CONSTITUTION:A cylinder 8 having a collar 8a is protruded axially from an iron core retainer 6 mounted on the end face of a rotor 4. A mounting member 11 having elasticity mounted integrally with a balance piece 10 is elastically engaged with the collar to balance the rotor. In this manner, the balancing work can be facilitated, the removal of the piece can be eliminated, and the deformation of the rotor coil 7 can also be prevented. |
