DYNAMIC DAMPER

摘要

A dynamic damper in which the inner diameter (D2) of a first hole part (32) formed at the axial one end part of a body part (24) overlapped with a weight part (26) in the radial direction is set smaller than the inner diameter (D3) of a second hole part (34) formed at the axial other end part of the body part (24) not overlapped with the weight part (26) in the radial direction and tightened with a band member (20) (D3 > D2). The outer diameter (D1) of a drive shaft (12) to be press-fitted into the first and second hole parts is set larger than the inner diameter (D2) of the first hole part (32) and the inner diameter (D3) of the second hole part (34) (D1 > D3 > D2).
