PROBLEM TO BE SOLVED: To provide a buffer stopper 1 capable of increasing an absorbable energy amount without depending on only a maximum compression displacement amount of a buffer 12 and reaction to compression.SOLUTION: A buffer stopper includes an annular stopper body 11 mounted on one 3 of two members relatively movable in an axial direction and opposed to an end face 21a formed on the other 2 of the two members, and an annular buffer 12 disposed integrally with the stopper body 11. The buffer 12 is composed of a rubber elastic material, and has a projecting end portion 121 extended in the axial direction toward the end face 21a side with respect to an end portion of the stopper body 11 facing the end face 21a side, and capable of being closely kept into contact with the end face 21a, and a seal lip 122 slidably closely kept into contact with a cylindrical face 22a formed on the other 2 of the two members.SELECTED DRAWING: Figure 1

    【課題】緩衝体12の最大圧縮変位量や圧縮に対する反力にのみ依存することなく、吸収可能なエネルギー量を大きくすることの可能な緩衝ストッパ1を提供する。【解決手段】軸方向相対移動可能な二部材のうちの一方3に取り付けられ二部材のうちの他方2に形成された端面21aと対向する環状のストッパ本体11と、このストッパ本体11に一体的に設けられた環状の緩衝体12を備え、この緩衝体12はゴム状弾性材料からなるものであって、端面21a側を向いたストッパ本体11の端部より端面21a側へ向けて軸方向へ延び、端面21aと密接可能な突出端部121と、二部材のうちの他方2に形成された筒状面22aと摺動可能に密接されるシールリップ122が形成される。【選択図】図1
