。[Claims for Utility Model Registration] A body having a substantially cylindrical valve chamber and a vent communicating with the valve chamber through a valve hole formed in the upper part of the valve chamber; The fuel tank is equipped with a float having a specific gravity greater than that of the fuel, and a spring that urges the float upward with a load smaller than its own weight, and is mounted on the upper part of the fuel tank, and normally the valve hole is When the valve is opened, vapor generated in the fuel tank can be discharged to the outside through the vent, and the valve hole is closed when the fuel level rises above a predetermined level or when the vehicle rolls over. In the fuel cut-off valve that prevents fuel from flowing out, a cylindrical portion is formed that projects downward from the periphery of the valve hole and has a pointed lower end periphery; A fuel cut-off valve characterized in that a concave portion is formed with a tapered inner circumferential surface that comes into contact with the lower end of the cylinder.
