Abstract:
When a flexible diaphragm provided inside an accumulator housing comes into contact with the peripheral edge of an opening to a gas filling port, in order to prevent the diaphragm from being damaged due to differential pressure occurring between a gas filled chamber and a space inside the gas filling port, when the diaphragm is in contact with the peripheral edge of the opening of the gas filling port, a communication passage, which allows communication between the gas filled chamber and the space inside of the gas filling port, is formed by, for example, unevenness being provided to one or both of the diaphragm and the peripheral edge of the opening to the gas filling port.
