<p>PROBLEM TO BE SOLVED: To reduce the number of components of an accumulator using a metal bellows by providing a guide function of a movable plate to a seal member constituting a valve. SOLUTION: A seal member 18 mounted on an outer periphery of the movable plate 13 with an end fixed on the metal bellows constitutes a valve which prevents liquid from flowing into a liquid inlet/outlet port from a liquid chamber, when the length of a metal bellows exceeds a given length. The seal member 18 integrally forms a first lip 18a and a second lip 18b coming into contact with/separating from an inner peripheral small diameter portion of a shell.</p> |
