PROBLEM TO BE SOLVED: To provide a fitting for a beverage container which completely prevents foreign matters and sewage from intruding thereinto by eliminating a clearance between a ferrule and a mounting member and enables the reduction of maintenance operations. SOLUTION: The fitting comprises: a ferrule for the beverage container having a valve seat part and a mounting part formed integrally with each other; a down tube supported on the mounting part, a gas valve fitted to the upper end part of the down tube; and a beverage valve installed at the upper end inner part of the down tube. The gas valve comprises a metal core 31a and a largely flexible valve member. The flat outer peripheral part of the core comprises a constant diameter part 311 with a constant diameter and small diameter parts 312a with a diameter smaller than that of the constant diameter part. The flat outer peripheral part is symmetrical with respect to both a first straight line A passed through the center of the constant diameter part and a second straight line B crossing perpendicularly to the first straight line at its center. The gas valve is allowed to pass the center hole of the valve seat part in a tilted state. In a horizontal state, however, the gas valve is not allowed to pass the center hole of the valve seat part, and is replaceable through the center hole of the valve seat part.
