PROBLEM TO BE SOLVED: To provide a rotation balance adjustment structure in a damper capable of sufficiently correcting unbalance to specifications, shortening a cycle time for correcting unbalance, and free from remarkable degradation of strength of a product even when the rotation balance adjustment structure is disposed.SOLUTION: In a structure for adjusting rotation balance of a damper by mounting a balance adjustment mass on a part of the circumference of the annular damper, a mass mounting groove is formed on an inner diameter portion of a hub as a component of the damper, and the mass is mounted on a part of the circumference of the mass mounting groove. As a mounting structure, a press-fitting margin to the mass mounting groove is set in the mass, and the mass is press-fit in the mass mounting groove, or the mass is mounted in the mass mounting groove by utilizing such spring characteristic of the mass that the mass is elastically deformed into the shape of a leaf spring. |
