PROBLEM TO BE SOLVED: To satisfactorily maintain the function of an air cleaner by preventing water droplets entering the inside of a dust member from being sucked into the suction port of the air cleaner.SOLUTION: A suction port 20C of an air cleaner 20 disposed in a building cover 14 of a hydraulic shovel 1 and an air outlet 21B of a precleaner 21 attached to a precleaner connection port 27C of a precleaner attachment member 27 constituting the building cover 14 are connected via a duct member 30 disposed in the building cover 14, and the suction port 20C of the air cleaner 20 is covered from above by an inclined plate 36 disposed between the precleaner connection port 27C and an air cleaner connection port 33 of the duct member 30. Thus, even when water droplets 37 enter the inside of the duct member 30 via the attachment opening 17B of a top cover 17 and the precleaner connection port 27C or the like, the water droplets 37 are received by the inclined plate 36 so that the water droplets can be prevented from being sucked into the suction port 20C of the air cleaner 20. |
