PROBLEM TO BE SOLVED: To provide a bump stopper capable of smoothing an increase in a load against an increase in a compression amount.SOLUTION: A bump stopper 100 is obtained by molding, the outer periphery thereof is formed in a bellows shape, and a first valley part 110a and second valley part 110b in the bellows shape are configured so that the diameter of the first valley part 110a is smaller. When a molding material is filled into a cavity of a die during the molding, in the bump stopper 100 where the molding material is filled from the rear end side to the front end side, the first valley part 110a and second valley part 110b have a plurality of recessed parts 120a and 120b for rigidity reduction at a predetermined interval to the circumferential direction so as to uniform the rigidity in a portion of each valley part. |
