The purpose of the invention is to provide an accumulator, which is equipped with an emergency safety mechanism capable of operating at a pressure lower than when a rupture disk is provided locally on the circumferential surface of the stay and the stay of which can be manufactured by press working alone. In order to achieve the purpose, the accumulator comprises an emergency safety mechanism that releases pressure inside the housing towards the oil port so that the housing does not explode due to an increased pressure inside the housing during an emergency such as a fire, etc. The emergency safety mechanism comprises a beveled section at the corner between the cylindrical section and the end face of the stay. During an emergency, the beveled section buckles at the base region thereof. When the beveled section buckles, the bellows cap or a held member and the end face section of the stay separate and a pressure-releasing channel is formed between the bellows cap or held member and the beveled section. |
