Abstract: PROBLEM TO BE SOLVED: To provide a fuel cooling device capable of efficiently preventing the generation of vaporized fuel by cooling a source of the vaporized fuel. SOLUTION: The fuel cooling device has a cooler for cooling fuel in a fuel tank. The cooler is disposed in such a manner that at least a part thereof contacts with the surface of the fuel in the fuel tank. Preferably, the portion of the cooler that contacts with the fuel surface floats on the fuel surface. Since the fuel cooling device having this constitution cools the fuel surface where the vaporized fuel is generated, it is possible to efficiently cool the fuel in the fuel tank, thereby preventing the generation of the vaporized fuel.
