The valve body 2 is provided with a main float guide tube 4 that opens into the fuel tank 1 and houses a main float 6 with an open main valve seat 5 connected to the ventilation passage 3 at the top thereof. is a main float 6 equipped with a main valve portion 6A that opens and closes the main valve seat 5, and whose apparent specific gravity is greater than the specific gravity of the fuel stored in the fuel tank 1. The main float 6 is biased toward the side that closes the main valve seat 5 with a first spring 9, and the buoyancy of the main float 6 causes the main valve portion 6A to close the main valve seat 5. On the other hand, the main float 6 has a sub-valve seat connected to the inside of the fuel tank 1, opened at the upper part corresponding to the main valve seat diameter φD of the main valve seat 5, and having a sub-valve seat diameter φd smaller than the main valve seat φD. Sub-float guide cylinder 6 with valve seat 6C open
A sub-float 10 is provided with a sub-valve part 10A for opening and closing the sub-valve seat 6C, and the sub-float guide cylinder has a sub-float 10 having an apparent specific gravity greater than the specific gravity of the fuel stored in the fuel tank 1. The secondary valve seat 6 is equipped with a second spring 11 whose load is smaller than the own weight of the float 10.
A fuel cutoff valve is constructed by arranging a sub-float 6C biased toward the side that closes C, and closing the sub-valve seat 6C by the buoyancy of the sub-float 10.
