Abstract:
An accumulator capable of suppressing collision of a metal bellows with a pressure vessel. A partition unit  300  includes: a tubular metal bellows  310 , one end of which is side fixed to a pressure vessel  200  and which expands and contracts according to pressure in a fluid chamber and pressure in a gas chamber; and a bellows cap  320  which is fixed to another end side of the metal bellows  310 , the partition unit  300  further including: a seal member  330  which is provided between the bellows cap  320  and a port  221  and seals a working fluid on the side of the fluid chamber via the metal bellows  310  when the metal bellows  310  contracts; and a sliding unit  350  which is fixed to the bellows cap  320  and slides in an expansion/contraction direction of the metal bellows  310  relative to a stay  400.

Claim (Index 6):
The accumulator according to  claim 1 , wherein\n one end of the annular member is fixed to an inner wall surface on a port side in the pressure vessel, and another end of the annular member has a bottom plate portion, in which a through hole is formed, and the sliding unit includes a fixed member which is fixed to the bellows cap and is disposed so as to be slidable relative to a bearing provided on an inner peripheral surface of the through hole.
