To provide a damper gear capable of preventing a mass body from falling down when an axial length of the mass body is increased.SOLUTION: A damper gear comprises: an installation member (30) mounted on the outer periphery of a power transmission shaft (1); a mass body (10) disposed in an outer diameter direction of the installation member (30) in a radial direction of the power transmission shaft (1); and a connection member (20) composed of an elastic body and connecting the installation member (30) to the mass body (10). The connection member (20) includes: a plurality of first connection members (21) disposed on the one side of the axial direction of the power transmission shaft (1) on an inner periphery of the mass body (10); and a plurality of second connection members (22) disposed on another side of the axial direction of the power transmission shaft (1) on the inner periphery of the mass body (10), in which the first connection member (21) and the second connection member (22) are alternately disposed in the circumferential direction of the mass body (10).SELECTED DRAWING: Figure 2

    【課題】質量体の軸方向の長さを長くした場合に質量体の倒れを防止し得るダンパ装置を提供する。【解決手段】動力伝達軸(1)の外周に装着される装着部材(30)と、動力伝達軸(1)の径方向において装着部材(30)の外径方向に配置される質量体(10)と、弾性体で構成され装着部材(30)と質量体(10)とを連結する連結部材(20)と、を備え、連結部材(20)は、質量体(10)の内周における動力伝達軸(1)の軸方向の一方側に配置される複数の第一連結部材(21)と、質量体(10)の内周における動力伝達軸(1)の軸方向の他方側に配置される複数の第二連結部材(22)と、を有し、第一連結部材(21)と第二連結部材(22)とは、質量体(10)の周方向において交互に配置されることを特徴とする。【選択図】図2
