PROBLEM TO BE SOLVED: To provide a bump stopper capable of smoothening increase of a load to increase of a compression amount.SOLUTION: In a foam polyurethane-based bump stopper 100, an outer peripheral surface has a bellows shape, and a plurality of crest parts (first crest part 111, second crest part 112, third crest part 113) and trough parts (first trough part 121, second trough part 122, third trough part 123) in the bellows shape has a smaller diameter toward a tip side. For the diameter of a crest part as X, and the diameter of a trough part adjacent to the rear end side of the crest part as Y, a value of Y÷X is set to be made smaller toward the rear end side from the tip side.SELECTED DRAWING: Figure 1 |
