Abstract
Disclosed are a bump stopper and a manufacturing method therefor which can maintain the shock-absorbing characteristics and durability performance constantly for a prolonged period of time regardless of the temperature or humidity of the usage environment, which can maintain a constant dimensional precision for a finished product, which is excellent in material yield rate and manufacturing efficiency, and which is low-cost, lightweight, recyclable, and ecological. A bump stopper (1) is provided in the vicinity of a rod of a shock absorber to elastically limit the stroke of the shock absorber at the time of the contraction thereof and to absorb the shock generated at that time. The bump stopper includes a hollow cylindrical bellows part (11) which extends along a stroke direction S of the shock absorber. The bellows part is formed by thinning thermoplastic resin and is constructed such that first parts (12) which are bulged outward and second parts (13) which are recessed inward are provided alternately and repeatedly in the stroke direction S.
