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.
