Claims

[Scope of Claim for Utility Model Registration] A valve chamber mounted on the upper wall of a fuel tank, and a float valve disposed within the valve chamber, the float valve adjusting according to the height of the fuel liquid level. A fuel cut-off valve configured to open and close a valve hole in the valve chamber, wherein the float valve has a horizontal surface, and a sub-float formed of a material having a specific gravity smaller than the apparent specific gravity of the float valve, the float valve having a horizontal surface. The sub-float is arranged coaxially toward the outer periphery of the float valve, and the sub-float has a pressing surface above the horizontal surface that comes into contact with a horizontal surface of the float valve at least when the float valve is closed. Uell cutoff valve.
