ENGINE COOLING DEVICE

PROBLEM TO BE SOLVED: To provide an engine cooling device capable of cooling a radiator or an engine sufficiently with the running wind.SOLUTION: The engine cooling device includes a first wind passage 16 to lead the running wind via radiator 5 to the engine 8 behind the radiator, a second wind passage 17 diverging from the radiator outlet side of the first wind passage 16, directed toward the engine from a direction different from the first wind passage, and leading to engine the wind of a cooling fan 27 as cooling wind, and wind passage change-over means 31a and 31b which changes over the first and second wind passages from one to the other and uses the wind passages 16 and 17 selectively between two cooling modes, i.e., cooling with the running wind and cooling by the fan. Accordingly the running wind is led to the engine directly via the first wind passage as free of passing through the cooling fan and the radiator, so that it is possible to cool the radiator and engine with the running wind having a sufficient flow velocity and wind quantity.
