PURPOSE:To improve the cooling effect for a supercharge pump by horizontally arranging an engine in one-sided form at the back of a traveling-wind taking-in port which is opened at the front of a chassis and forming a cooling-wind passage which communicates to the taking-in port on the other side and arranging the supercharge pump in said passage. CONSTITUTION:A traveling-wind taking-in port 2 is opened onto the front surface of an engine room 1, and a double overhead cam type engine 3 is mounted, one-sided at the rear part of the taking-in port 2, setting a crankshaft 4 in the direction of width, and a radiator 5 for cooling the engine with water is arranged between the taking-in port 2 and the engine 3. Further, a louver 1b upwardly opened at the rear part of the engine room 1 and a cooling-wind passage 6 which communicates to under the floor of a chassis are formed behind the taking-in port 2, and a transmission 7 is arranged at the lower position of the passage 6, and a supercharge pump 8 is arranged in the cooling-wind passage 6 at the position over the transmission 7. Therefore, the supercharge pump 8 can be exposed to a large quantity of traveling wind, and the cooling effect can be improved.
