Abstract

PURPOSE:To eliminate occurrence of stress concentration and improve durability, in a film used for an oil damper or the like, by providing straight parts in its both end parts and a tapered part in its intermediate part. CONSTITUTION:There are integrally formed a large thickness part 31, press attached by a stopper 6 to the opening part of a cylinder 1, medium thickness straight part 32, formed to cylindrical shape thinner than said part 31, tapered part 33, formed to thinly tapered shape, medium thickness straight part 34, further formed to cylindrical shape, and large thickness part 35, press attached to a piston rod 4. In this way, curved deformation is smoothly performed and not less than a necessary amount of stress is not caused partially in a film 5, resulting in the improvement of durability. Further deterioration of the film 5 can be prevented to increase its reliability.
