装置。 A fuel cut-off valve is provided between an atmospheric side and an internal space of a fuel tank, and the fuel cut-off valve has a valve seat opening that communicates between the atmospheric side and the internal space of the fuel tank. and a float valve that moves up and down to open and close the valve seat opening in accordance with the rise and fall of the fuel oil level in the fuel tank, and the float valve is formed with an air chamber to increase its buoyancy. The float valve moves upward in response to a rise in the fuel oil level in the fuel tank and closes the valve seat opening, thereby preventing the fuel in the fuel tank from flowing out to the atmosphere. 1. A fuel cut-off valve device, characterized in that an air chamber formed in the float valve is partitioned into a lattice shape using a wall member or the like.
