ABSTRACT:
A fuel cutoff valve comprises a casing and a float mechanism having a float and a seat portion. An upper vent hole is formed in the upper wall portion of the float, and a side portion communication hole is formed in the side wall portion. The passage area of the side portion communication hole is set so as to allow a large volume of vapors entering the float chamber to escape into the valve chamber. The passage area of the upper vent hole is set so that vapor entering the float chamber when the vehicle inclines escapes into the valve chamber, and the float chamber fills with fuel lifting the float, whereas when the vehicle turns sharply, the float is lifted without the float chamber filling with fuel.
