Abstract
Disclosed is a valve being attached to a fuel tank, the valve permitting a vaporized fuel to flow out and inhibiting a liquid fuel from flowing out. The valve includes a cover and a case. For example, the cover is bonded to an upper portion of a fuel tank, is independent of the fuel tank, and includes a connecting surface to be connected to the fuel tank and a flow-out passage in which a vaporized fuel flows out. The connecting surface has a connector portion formed of a resin exhibiting a good bondability to the fuel tank. The case is screwed to the cover, and includes an evaporator opening and a floating valve. The evaporator opening communicates with the flow-out passage. The floating valve opens or closes the evaporator opening.
