PROBLEM TO BE SOLVED: To provide a dynamic damper 10 assembled into an inner periphery of a propeller shaft, which secures excellent followability to variation of an inner diameter dimension of the propeller shaft, and excellent durability of an elastic support member.SOLUTION: A dynamic damper for a propeller shaft includes a structure that elastically connects between a sleeve 11, on an outer peripheral surface of which an elastic layer 14 comprising a rubber elastic body is provided, and a mass body 12, arranged concentrically on an inner periphery of the sleeve 11, by an elastic support member 13 comprising a plurality of rubber elastic bodies arranged in a circumferential direction. In the sleeve 11, a plurality of opening parts 11a is positioned on an outer diameter side of the elastic support member 13. The elastic support member 13 and the elastic layer 14 continue to each other through the opening parts 11a.SELECTED DRAWING: Figure 1
【課題】プロペラシャフトの内周に組み込まれるダイナミックダンパ10において、プロペラシャフトの内径寸法のばらつきに対する良好な追随性と、弾性支持部材の良好な耐久性を確保する。【解決手段】外周面にゴム弾性体からなる弾性層14が設けられたスリーブ11と、このスリーブ11の内周に同心的に配置した質量体12との間を、円周方向複数箇所に配置したゴム弾性体からなる弾性支持部材13によって弾性的に連結してなる構造を備え、スリーブ11に、弾性支持部材13の外径側に位置する複数の開口部11aが形成され、弾性支持部材13と弾性層14が、開口部11aを通じて互いに連続している。【選択図】図1
