Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel shut-off valve 10 which prevents excessive fueling beyond a predetermined liquid level.SOLUTION: The fuel shut-off valve 10 comprises: a casing 20 having a main valve chamber 21S and a sub valve chamber 31S; a main valve mechanism 40 stored in the main valve chamber 21S; and a sub valve mechanism 60 stored in the sub valve chamber 31S. The casing 20 includes a first communication passage 21P for connecting a fuel tank FT and the main valve chamber 21S and a second communication passage 31P for connecting the main valve chamber 21S and the sub valve chamber 31S. When a liquid level of fuel in the fuel tank FT reaches to a first liquid level FL1, the casing 20 flows the fuel in the fuel tank FT to the main valve chamber 21S via the first communication passage 21P by differential pressure of tank internal pressure and the main valve chamber 21S so as to close a connection passage 22a by the main valve mechanism 40. When the liquid level of the fuel in the fuel tank FT reaches to a second liquid level FT2, the second communication passage 31P is closed by rising of the sub valve mechanism 60.
