Abstract:

Provided is an accumulator that suppresses contaminants from entering a gap (S) between a housing and a gas valve that fits a concavity of the housing. The accumulator (100) is provided with: a housing (110) having an injection opening (112b) into which pressurized gas is injected; and a gas plug (150) that occludes the injection opening (112b). By means of a welded section (151) of the gas plug (150) melting, the gas plug (150) is welded to the housing (110), sealing pressurized gas in the housing (110). The housing (110) has: a concavity into which the gas plug (150) for occluding the injection opening (112b) is fitted, and at the bottom surface (110a) of which the welded section (151) is melted to weld the gas plug (150); and an inclined surface (110c) that extends from the edge of the concavity in a manner such that the distance from the center of the injection opening (112b) becomes longer towards the outside of the housing (110). The gas plug (150) has a flange (152) that contacts the inclined surface (110c) in the state of being fitted and welded to the concavity.
