To prevent degradation in the durability of a damper device.SOLUTION: A shock absorbing member 10 arranged between a flange-like part 84 with an annular surface overhanging from an outer-peripheral surface of a shaft 40 moving in the axial direction and an annular receiving part 98 overhanging to the shaft 40 side from an outer-peripheral surface of a cylindrical housing 34 housing the shaft 40, includes: an annular elastic body 12 surrounding the shaft 40 between an annular surface 84a and the receiving part 98 and facing the inner-peripheral surface of the housing 34; and an annular body 11 installed on the elastic body 12 and facing the annular surface 84a and has higher rigidity than the elastic body 12. The annular body 11 has a supporting part 111 facing the annular surface 84a and a protrusion part 112 invading into the elastic body 12 from an opposing surface to the elastic body 12 in the support part 111.SELECTED DRAWING: Figure 2
【課題】ダンパ装置の耐久性を低下させないこと。【解決手段】衝撃吸収部材10は、軸方向に移動するシャフト40の外周面から張り出す環状面を有する鍔状部84と、シャフト40を収容する筒状のハウジング34の内周面からシャフト40側へ張り出す環状の受部98との間に配置される衝撃吸収部材10であって、環状面84aと受部98との間においてシャフト40を包囲し、ハウジング34の内周面に対向する環状の弾性体12と、弾性体12に設けられ、環状面84aに対向する環状体11であって、弾性体12よりも剛性が高い環状体11と、を具備し、環状体11は、環状面84aに対向する支持部111と、支持部111における弾性体12との対向面から弾性体12に入り込む突起部112と、を有する。【選択図】図2
