Abstract
A tank includes a liner, a neck that has a communicating orifice, a metal cylindrical member that is inserted into a lower end portion of the communicating orifice, and a valve that is inserted into the communicating orifice, wherein a lower end portion of the valve is inserted into the metal cylindrical member. The liner includes a wrap-around portion that wraps around to inside of the communicating orifice, and to contact with an outer circumferential face of the metal cylindrical member. A first O-ring is disposed in a circumferential direction between an inner circumferential face of the wrap-around portion and the outer circumferential face of the metal cylindrical member. A second O-ring is disposed in the circumferential direction between an inner circumferential face of the metal cylindrical member and an outer circumferential face of the lower end portion of the valve.
