The fitting member is made of a synthetic resin. An O-ring is interposed between a circumferential surface of the adapter and the fitting member. The adapter is a synthetic resin member, and includes a contact portion brought into contact with the adapter and a pressing portion pressing the valve. The pressing member is welded to the fitting member.
