PROBLEM TO BE SOLVED: To provide a fuel cooling device of such an arrangement that a cooling fan is installed on one side face of an engine and the cooling wind is supplied to a radiator from the fan, whereby the cooling efficiency for the fuel can be enhanced while the cooling efficiency for the cooling water by the radiator is well maintained. SOLUTION: The fuel cooling device is configured so that the cooling fan is installed on one side face of the engine and the cooling wind is supplied to the radiator from the fan, wherein a fuel passage 26 is provided at the side face of a fan shroud 3 where the fan 9 is mounted, and the fuel flowing in the passage 26 is cooled by the wind supplied from the fan 9. The amount of heat radiation can be adjusted by the length of the fuel path, and can be increased to a great extent by meandering the fuel passage 26 and setting off large the cooling path for the fuel, to ensure enhancement of the cooling effect. Further, fins 43 for cooling are provided on the inside of the fan shroud 3. COPYRIGHT: (C)2003,JPO
