动力减振器
摘要：
本发明提供一种动力减振器，其中形成在主体(24)的在径向上与质量部(26)重叠的一轴向端处的第一孔部(32)的内径(D2)设定成小于形成在主体(24)的在径向上不与质量部(26)重叠并用带部件(20)紧固的另一轴向端处的第二孔部(34)的内径D3(D3＞D2)。待压配到第一孔部和第二孔部中的驱动轴(12)的外径(D1)设定成大于第一孔部(32)的内径(D2)并大于第二孔部(34)的内径(D3)(D1＞D3＞D2)。
摘要（英）：

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 witha 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).
