PROBLEM TO BE SOLVED: To provide a bump stopper hardly buckled.SOLUTION: A cylindrical main body portion made of urethane foam is provided with a first groove recessed toward a radial inner side and extended in a circumferential direction, on its outer peripheral face. A ring member harder than the urethane foam is mounted in the first groove and fixed to the outer peripheral face of the main body portion. The total length L1 in an axial direction, of the main body portion is 66 mm or more. L2/L3 obtained by dividing an axial distance L2 from a rear end of the main body portion to a face at a rear end side, of the ring member by an axial distance L3 from a tip of the main body portion to a face at a tip side, of the ring member satisfies 3≤L2/L3≤4.2.SELECTED DRAWING: Figure 2

    【課題】座屈し難くできるバンプストッパを提供すること。【解決手段】ウレタンフォーム製の円筒状の本体部は、径方向の内側へ向かって凹み周方向へ延びる第1溝が、外周面に形成される。ウレタンフォームよりも硬いリング部材は、第1溝に装着されて本体部の外周面に固定される。本体部は、軸線方向の全長L1が66mm以上である。本体部の後端からリング部材の後端側の面までの軸線方向の距離L2を、本体部の先端からリング部材の先端側の面までの軸線方向の距離L3で除したL2/L3は、3≦L2/L3≦4.2を満たす。【選択図】図2
