The accumulator main body is divided into a gas chamber filled with compressed gas at a predetermined pressure and a control fluid chamber into which control fluid flows through a flow path, and a bellows is formed in response to the pressure difference between the gas chamber and the control fluid chamber. In a bellows type accumulator configured to expand and contract, when the pressure in the control fluid chamber decreases by a predetermined amount, the flow path is shut off and a predetermined amount of control fluid is retained in the control fluid chamber to maintain the pressure. A bellows type accumulator characterized by being provided with a means.
