することを特徴とするアキユムレータ。[Claim for Utility Model Registration] A back pressure chamber and a pressure accumulation chamber are separated by a flexible bladder in a hollow housing, high pressure gas is sealed in the back pressure chamber, and liquid is injected into the pressure accumulation chamber. In an acumulator that introduces the liquid and stores the liquid under pressure, the bladder is formed by laminating a rubber layer made of a rubber-like elastic material and a non-rubber layer made of a non-permeable material that blocks the permeation of gas. The rubber layer is located in the back pressure chamber and defines a part of the back pressure chamber, and the rubber layer is located on the pressure accumulation chamber side and defines a part of the pressure accumulation chamber. Accumulator.
