To provide a fuel shut-off valve allowing a little flow of fuel into a valve chamber through an air hole when a vehicle is oscillated without causing the upsizing of a casing.
This fuel shut-off valve 10 includes a casing 20 with a casing body 30 forming a connection passage 45b and the valve chamber 20S and a lid body 50 welded to the upper part of the casing body 30, and a float mechanism 60 with a float 61 stored in the valve chamber 20S and raised/lowered by a fuel liquid level in the valve chamber 20S thereby opening/closing the connection passage 45b. The casing body 30 includes a cylindrical sidewall part 31, and a flange 31a formed in the upper part of the sidewall 31 for welding the lid body 50. Moreover, a lead-in groove 31e vertically reaching the flange 31a is formed on the peripheral surface of the sidewall part 31, and the air hole 31d passing through the flange 31a along the lead-in groove 31e, and connected to the valve chamber 20S, is formed.
