摘要： To prevent abnormal noise generation and bellows breakage by rattling, a metallic bellows type accumulator (1) comprising a housing (2) provided with a shell (3) and a gas end cover (4), a metallic bellows (7) arranged inside the housing (2), and a volume controlling spacer (22) fixed inside the gas end cover (4) is structured such that the spacer (22) is formed in a disc shape by a predetermined resin material, has a hole part (25) in a center of a flat surface, has a slit part (26) at one position on a circumference, has a larger outer diameter than an inner diameter at a position where the spacer is inserted in the gas end cover (4), is inserted to the gas end cover (4) in a state that the outer diameter is contracted, and is fixed inside the gas end cover (4) by its elastic restoring force.
