PROBLEM TO BE SOLVED: To provide a cushioning stopper 1 capable of achieving both of securing of excellent shock absorbing performance by a cushioning body 12 and prevention of metal contact.SOLUTION: A cushioning stopper disposed between an end surface 21a of a housing 2 and an end surface 31a of a shaft 3 includes: a collar 11 having a supporting cylinder 11a which is externally fitted to the shaft 3, and a flange 11b which is formed on one end thereof and can be abutted to the end surface 31a of the shaft 3; a cushioning body 12 which is held on an outer periphery of the supporting cylinder 11a and can be brought into pressure contact with an inner peripheral surface 22a of the housing 2 by compression in an axial direction and expansion deformation in a radial direction; and a sliding ring 13 which is held on an outer periphery of the cushioning body 12 and can be moved to the axial direction with the collar 11 and the cushioning body 12. An axial length L of the supporting cylinder 11a is shorter than an axial length of the cushioning body 12 when the cushioning body 12 is compressed in the axial direction until it is brought into pressure contact with the inner peripheral surface 22a of the housing 2 by the expansion deformation, and a diameter enlargement recession 22b allowing diameter increase and deformation of the sliding ring 13 which is moved to the axial direction in the axial compression process of the cushioning body 12 is formed on the inner peripheral surface 22a of the housing 2.SELECTED DRAWING: Figure 1

    【課題】緩衝体12による優れた衝撃吸収機能の確保と、金属接触の防止の双方を満足する緩衝ストッパ1を提供する。【解決手段】ハウジング2の端面21aと軸3の端面31aの間に、軸3に外挿される支持筒部11a及びその一端に形成されて軸3の端面31aと当接可能な鍔部11bを有するカラー11と、支持筒部11aの外周に保持され、軸方向圧縮と共に径方向への拡張変形によってハウジング2の内周面22aに圧接可能な緩衝体12と、この緩衝体12の外周に保持されカラー11及び緩衝体12と共に軸方向へ移動可能な摺動環13を備え、支持筒部11aの軸方向長さLは、緩衝体12が拡張変形によってハウジング2の内周面22aに圧接するまで軸方向圧縮されたときの軸方向長さより短く、ハウジング2の内周面22aに、緩衝体12の軸方向圧縮過程で軸方向移動される摺動環13の拡径変位を許容する拡径凹部22bが形成されている。【選択図】図1
