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.
