Provided is an accumulator, which: is capable of reducing the pressure difference that is generated by differences in coefficients of thermal expansion when liquid trapped in the liquid chamber and a sealed gas undergo thermal expansion during zero-down, thereby limiting the occurrence of plastic deformation in the bellows; and has a structure in which the parts are small and few in number. To achieve said purpose, the accumulator has a sealing member held on the port hole-side of the bellows cap via a seal holder. When operation of the machine is stopped and the pressure inside the pressure piping decreases, the sealing member contacts the sealing section and closes the liquid chamber. If liquid trapped in the liquid chamber when the liquid chamber is closed undergoes thermal expansion, the bellows cap moves in the direction away from the sealing section while the sealing member is still in contact with the sealing section. Since the sealing member is a rigid plate, the outer circumferential surface of which is covered by a flexible section obtained from a rubber-like elastic body, the flexible section allows relative movement of the bellows cap by undergoing shear deformation as a result of engagement with the seal holder.

Provided is a quick connector which enables, when the elastically deformable claw of a retainer and the elastically deformable claw of a checker are disposed so as to be adjacent to each other in the axial direction, the engagement of a pipe body with the retainer to be reliably confirmed. Checker's axial elastically deformable claws (52, 52) are configured so that the front end side thereof can bend and deform in the axial direction. When the bending and deformation of the checker's axial elastically deformable claws (52, 52) are restricted by a retainer's elastically deformable claw (49), which can be expanded in diameter, while the claw (49) is expended in diameter, the claws (52, 52) are maintained engaged with second engagement sections (46) of the retainer body (42). When engaged with the second engagement sections (46) of the retainer body (42), the sliding motion of the checker's axial elastically deformable claws (52, 52) from a first position in a set radial direction relative to the retainer body (42) is restricted. The checker's axial elastically deformable claws (52, 52) can be disengaged from the second engagement sections (46) of the retainer body (42) when the shape of the retainer's elastically deformable claw (49) which can be expanded in diameter is restored, and this enables the claws (52, 52) to slide from the first position to a second position in the set radial direction relative to the retainer body (42).
