PROBLEM TO BE SOLVED: To provide a bump stopper which can smoothen a change of a spring constant with respect to an increase of a compression amount.SOLUTION: In a bump stopper 100 whose external peripheral face is formed of a bellows shape, a plurality of crest parts (first crest part 111, second crest part 112, third crest part 113 and fourth crest part 114) at the bellows shape, and trough parts (first trough part 121, second trough part 122 and third trough part 123) are formed so as to be reduced in diameters as progressing toward tip sides. At an internal peripheral face side, annular recesses (fourth annular recess 141, fifth annular recess 142 and sixth annular recess 143) are formed inside a plurality of the trough parts (first trough part 121, second trough part 122 and third trough part 123).SELECTED DRAWING: Figure 1

    【課題】圧縮量の増加に対するバネ定数の変化を滑らかにすることのできるバンプストッパを提供する。【解決手段】外周面が蛇腹形状で構成されており、蛇腹形状における複数の山部(第1山部111,第2山部112,第3山部113,第4山部114)及び谷部(第1谷部121,第2谷部122,第3谷部123)は、先端側ほど径が小さくなるように構成されるバンプストッパ100において、内周面側には、前記複数の谷部(第1谷部121,第2谷部122,第3谷部123)の内側にそれぞれ環状凹部(第4環状凹部141,第5環状凹部142,第6環状凹部143)が形成されていることを特徴とする。【選択図】図1
