PROBLEM TO BE SOLVED: To facilitate the cleaning work of a radiation core by arranging a cavity member for forming a path for cooling air between a pair of radiation cores for successively passing the cooling air, forming at least one opening part on the circumferential wall of the cavity member, and mounting an openable and closable cover member on the opening part. SOLUTION: A cooling system 2 arranged within the engine room of a working machine is formed of a pair of radiation cores arranged so as to successively pass cooling air, or an oil cooler 8 and a radiator 9, and a cavity member 10 for forming a cooling air passage is arranged between the radiation cores 8, 9. The cavity body 18 of the cooling member 10 is formed by mutually bonding plate members into a square tubular shape, and opening parts 20, 24 are formed on the upper and lower parts of the cavity body 18. Upper and lower covers 22, 26 are attachably and detachably mounted on the opening parts 20, 24, respectively. The oil cooler 8 is rockably supported on the lower part of the cavity member 10 through a pair of hinge brackets 8a, 8b provided on the lower end of the support frame of the oil cooler 8.
