PROBLEM TO BE SOLVED: To bring about an improvement in terms of cleaning of a plurality of cooling devices, which are mounted on construction machinery, miniaturization, and a reduction in leakage of noise and temperature rise in an engine room by providing an arrangement structure of the cooking devices and a cooled air duct having a partition member also serving as an engine front cover. SOLUTION: The two cooling devices R are arranged in parallel in a mutually superposed manner. The partition member 60 is provided between the engine front cover C1 and an engine 22, which constitute the engine room 12 arranged at an interval between the cooling device R and the engine room 12 so as to house the engine 22. The partition member 60 is provided in such a manner as to also serve as the front cover C1. Air cooled by a cooling fan 20 for the cooling device R is guided so that a direction can be changed to a peripheral direction of the partition member 60 itself. The engine room 12, the engine 22 and the like are cooled by at least one cooled air circulating passage CD formed of a gap made between an engine cover C and the partition member 60.
