The present invention provides an outside air type accumulator for improving the durability of a bellows guide member. According to the present invention, a fixed end (27) of a metal bellow (21) is fixed and connected closely to a liquid chamber end cover member (18) not to allow a fluid to flow out, or fixed and connected closely to the inner wall of a tube body (1) in the liquid chamber end cover member (18) not to allow a fluid to flow out. A movable end (26) is located between the fixed end (27) and a gas chamber end cover member (17) in an axis direction. A bellows guide member (22) is mounted by being inserted into a gap of a corrugated wall (28) adjacent to the metal bellow (21), or fixed and connected to a bellows end cover (25), or fixed and connected to the movable end (26). The bellows guide member (22) is separated from a liquid chamber (3) by the metal bellow (21). Therefore, the accumulator (10) is characterized by using a gas volume conditioning solution not containing S and P, or using a gas volume conditioning solution in which each S and P is 10 ppm or less is contained. |
