Abstract: A rotor balance adjusting member and a rotor balance correction method are disclosed. The rotor balance adjusting member has a ring member fixed to a pulley concentrically and comprises a weight and a clip member which fixes the weight to the ring member. The ring member has an outer side fit-in slot, and inner side fit-in slot, an outer side stop slot, and an inner side stop slot. The clip member comprises an elastic material and moves in a circumferential direction regulated by the outer side fit-in slot and the inner side fit-in slot. The weight fixed to the clip member is arranged in a position which counters the inner side of the ring member when the clip member is fitted in the ring member.

Abstract: To provide a rotor balance adjusting member and the rotor balance correction method, which make easy Attachment and removal of the weight to a rotor prevent omission of the weight while a rotor is rating. A rotor balance adjusting member 1 has the ring member 2 fixed to the pulley 10 concentrically, weight 3, and the clip member 4 which fixes this weight to this ring member. The ring member has an outer side fit-in slot 21, an inner side fit-in slot 22, an outer side stop slot 23, and an inner side stop slot 24. In the state in which attachment and removal are free, and can be fitted in this outer side stop slot and this inner side stop slot, the clip member comprising of elastic material and having a motion of the circumferential direction regulated by this outer side fit-in slot and this inner side fit-in slot. The weight fixed to this clip member is arranged in the position which counters the inner side of the ring member, when this clip member is fitted in the ring member.
