PROBLEM TO BE SOLVED: To provide a fitting for a beverage container of an integration type in which service life of a gas valve is made longer, a sealing property of the gas valve is improved, and the cost of the gas valve can be reduced.SOLUTION: A fitting for a beverage container includes: a mouthpiece 93 of a beverage container; a valve seat 95 disposed at the inner circumferential side of the mouthpiece; an attachment part 94 integrated with the mouthpiece; a down-tube 5 supported by the attachment part; a gas valve 3 of a down-tube upper end; and a beverage valve 4 on the inner part of the down-tube upper end. The gas valve includes a core metal 31 and a valve member 32 formed integrally with the core metal, can pass through the center hole of the valve seat in an inclined state, and on the other hand, cannot pass through the center hole of the valve seat in a horizontal state. The core metal includes: a fixed diameter part in which a diameter as a planar outer peripheral shape is fixed; and a small diameter part in which a diameter is smaller than the fixed diameter part. The core metal is configured so that the small diameter part is formed as a shape so that the outer peripheral part of a core metal material where notches are formed in four positions symmetric about the center at the circular outer periphery is bent upward more on the outer peripheral side from the straight line connecting apexes on the inner circumferential side of the notches adjacent to each other. |
