PURPOSE:To miniaturize the whole cooling system by housing a radiator for cooling a water-cooled engine together with the engine inside a cover, so that the front face of the radiating core is faced toward the side surface of the cover, and by providing an air-passing port for introducing cooling air toward the core, on the side surface of the cover. CONSTITUTION:A water-cooled engine 19 and a cooling radiator 31 thereof are together housed inside a cover 40. The front face of the radiating core 32 of the radiator 31 is arranged so as to face toward the side surface of the cover 40. On the side surface of the cover 40 in front of the radiator 31, an air-passing port 42 for introducing cooling air toward the core 32 along the inside surface of the cover is opened. Thus, the air introduced through the air-passing port 42 is sufficiently introduced to the core 32 along the side surface of the cover to cool the core 32, so that cooling efficiency is enhanced, and also the radiator can be brought near to the engine, enabling the whole cooling system to be miniaturized. |
