Abstract
An accumulator is provided, which is aimed at stabilization in mounting state of a damping member while diminishing the impact on a metal bellows. In an accumulator (), a damping member () formed slidably at the inner circumferential surface of a pressure vessel () and suppressing the oscillation of a metal bellows () while keeping a gap between the metal bellows () and the inner circumferential surface of the pressure vessel () is mounted at at least one site of a plurality of annular valley parts of the metal bellows() including a plurality of annular crest parts and the plurality of annular valley parts alternately formed therein. In the damping member (), a radially inward tip is fitted with the valley part, and a radially outward tip is longer than the crest part of the metal bellows radially and outwardly.
