PROBLEM TO BE SOLVED: To provide a core rotational balance measurement rim, to which a core of various dimensions can be attached, and to provide a balancer having the same, and a rotational balance correction method using the balancer.;SOLUTION: The core rotational balance measurement rim 16 is provided with a pair of radial direction adapters 24A and 24B respectively disposed at coaxial positions with respect to the rim rotation central axis so that the core 22 can be retained by their abutments against leg parts 20A and 20B from the inside with respect to the radial direction. Each of the outer circumferential sides 25A and 25B of the radial direction adapters 24A and 24B is tapered, in which the radiuses of the outer circumferential sides 25A and 25B from the rim rotation central axis gradually increase toward the outer side with respect to the width direction of the rim. By fastening the radial direction adapters 24A and 24B so that the distance therebetween in which the core 22 is held is shortened, the leg parts 20A and 20B of the core 22 are positioned, while being slid along the outer circumferential sides 25A and 25B.;COPYRIGHT: (C)2006,JPO&NCIPI
