PROBLEM TO BE SOLVED: To provide a construction machine with which dust or the like adhering to a dust trapping means is easily cleaned, and the dust removed when cleaning a heat exchanger is easily discharged outside. SOLUTION: A dust trapping net 25 is attachably/detachably fitted to a cooling air duct 14 so as to cover a connection port 14G to a multiblade fan 19. The area of a net part 25c of the dust trapping net 25 is reduced to the connection port 14G, and since the dust trapping net 25 can be detached, the dust adhered to the dust trapping net 25 can be easily removed. In addition, a discharge port 14H formed in a bottom part of the cooling air duct 14 is opened/closed by a lid plate 26, and when a radiator 23 or the like is cleaned, the removed dust is directly discharged outside from the discharge port 14H by detaching the lid plate 26.
