PROBLEM TO BE SOLVED: To easily clean radiating cores aligned in parallel so that cooling air orderly passes by arranging a hollow member forming an air course of the cooling air between a pair of the radiating cores through which the cooling air orderly passes. SOLUTION: This cooling device 2 is set in an engine room 4 of a working machinery, and a hollow member 10 forming an air cource of cooling air 6 is arranged between a pair of radiating cores 8, 9 arranged so that the cooling air 6 orderly passes. In the meantime, an upper part hood 4b of the engine room 4 or an opening cover 4c of the hood 4b is opened, the hollow member 10 is lifted and extracted by holding a handle lOa by hand at the time of cleaning an oil cooler 8 and a radiator 9. Thereafter, dust attached and accumulated on the oil cooler 8 and the radiator 9 and dust accumulated in the air course of the hollow member 10 are cleaned by respectively using a brush, city water or a proper means made of compressed air, etc., by using a space from which the driving member 10 is extracted. Consequently, it is possible to easily clean the radiating cores 8, 9.
