Provided is an accumulator, which: is capable of reducing the pressure difference that is generated by differences in coefficients of thermal expansion when liquid trapped in the liquid chamber and a sealed gas undergo thermal expansion during zero-down, thereby limiting the occurrence of plastic deformation in the bellows; and has a structure in which the parts are small and few in number. To achieve said purpose, the accumulator has a sealing member held on the port hole-side of the bellows cap via a seal holder. When operation of the machine is stopped and the pressure inside the pressure piping decreases, the sealing member contacts the sealing section and closes the liquid chamber.
