摘要： An accumulator according to an embodiment includes, for example, a base member; a cover member welded to the base member, the cover member and the base member defining a pressure chamber therebetween; a stretchable partition member that partitions the pressure chamber into an inner chamber and an outer chamber; and a labyrinth structure provided in at least one of a first part of the base member and a second part of the cover member. The first part is located closer to the outer chamber than a welded part between the base member and the cover member. The second part is located closer to the outer chamber than the welded part, facing the first part.

摘要： An accumulator includes a pressure vessel including a first section and a second section joined to each other via a joint portion and a partition portion separating an interior space of the pressure vessel into a liquid chamber and a gas chamber so that a volume ratio between the liquid chamber and the gas chamber in the pressure vessel is variable. The first section includes a thread portion for fastening the accumulator to a support member. The second section includes an abutting portion disposed opposite to the thread portion across the joint portion in an axial direction of the thread portion and configured to abut on the support member when the accumulator is fastened to the support member.

摘要： An accumulator includes a pressure vessel and a partition portion separating an interior space of the pressure vessel into a liquid chamber and a gas chamber so that a volume ratio between the liquid chamber and the gas chamber in the pressure vessel is variable. The pressure vessel includes a first section including a thread portion for fastening the accumulator to a support member and a second section joined to the first section and formed by a single piece including a tool engagement portion capable of engaging with a tool for rotating the accumulator. The first section and the second section are fitted together by mating portions coaxial with the thread portion and the tool engagement portion.

摘要： A stabilizer device includes a stabilizer extending in a width direction of a vehicle, and a bush unit. The bush unit includes a bracket formed of metal, and a rubber bush. The rubber bush is formed of a plurality of bush pieces, and is fixed to the stabilizer by an adhesion layer. The adhesion layer is constituted of an adhesion member including an adhesive applied to inner surfaces of the bush pieces. A bonding display portion formed of a part of the adhesion member is provided at a corner on an end face of the bush piece.
