摘要： PROBLEM TO BE SOLVED: To provide a fuel shut-off valve for materializing an introduction passage 50P capable of easily discharging a fuel in a valve chamber 20S by a simple structure.SOLUTION: The fuel shut-off valve 10 includes a casing 20 in which the valve chamber 20S is formed by a casing body 30 and a bottom member 35 and a communicating hole 31a, a float mechanism 60 stored in the valve chamber 20S and a passage forming member 50. In the passage forming member 50, an introducing opening 57c of which one side is connected with the communication hole 31a and another side opens in a fuel tank FT is formed. The introducing opening 57c is formed at a position lower than the communication hole 31a and lower than a closing valve liquid level h1. An introduction passage 50P includes a sealing opening 52a closed by the fuel of which liquid level is lower than a full liquid level FL1.
