摘要： PROBLEM TO BE SOLVED: To provide an outside gas type or inside gas type accumulator configured to reduce a pressure difference to be generated by a difference in thermal expansion coefficients when liquid and filled gas confined in a liquid chamber are thermally expanded at a zero-down time, thus reducing a pressure difference between inner and outer sides of a bellows to prevent the occurrence of plastic deformation of the bellows. SOLUTION: A disc-like gasket is held in a floatable state to a surface on a stay side in a bellows cap by a gasket holder. The disc-like gasket moves together with the bellows cap at a steady operation time. The disc-like gasket moves together with the bellows cap to contact with an end surface portion of the stay, thereby closing the liquid chamber at a zero-down time. The bellow cap moves toward a position where liquid pressure and gas pressure balance while the disc-like gasket keeps contacting with the stay due to a difference of pressure receiving areas in both the surfaces when the liquid in the liquid chamber is thermally expanded at a zero-down time.
