The present invention provides a fitting for a beverage container capable of completely preventing foreign matter, dirty water and so on from entering by eliminating a gap between a ferrule and an attachment member, and enabling a reduction in maintenance operations. The fitting for a beverage container comprises a ferrule of a beverage container in which a valve seat portion and an attachment portion are provided integrally, a down tube supported by the attachment portion, a gas valve fitted onto an upper end portion of the down tube, and a beverage valve provided in the interior of the upper end portion of the down tube. The gas valve is constituted by a metallic core metal 31a and a valve member having increased flexibility, and a plan outer peripheral shape of the core metal comprises a constant diameter portion 311 having a constant diameter and a small diameter portion 312a having a smaller diameter than the constant diameter portion. The plan outer peripheral shape forms a graphic that is symmetrical to both a first straight line A passing through the center of the core metal and the constant diameter portion, and a second straight line B that intersects the first straight line in the center. The gas valve is capable of passing through a central hole in the valve seat portion when tilted but incapable of passing through the central hole in the valve seat portion when horizontal, and can be replaced through the central hole in the valve seat portion. |
