PROBLEM TO BE SOLVED: To prevent rain water from entering a heat exchanger side even if rain comes from an air discharging port toward the heat exchanger in a slant direction during a state in which the operation is stopped and discharging air is stopped.SOLUTION: An engine and a work machine main body driven by the engine are arranged in an engine room 4. A heat exchanger such as a radiator 7 for the engine is arranged at an opening part 8 of a front frame partition plate 6. Then, during operation, after cooling air passes from the engine room 4 into the heat exchanger, and passes through an air discharging chamber 5 in the front frame 1a and is discharged out of an air discharging port 2. The surface of such a heat exchanger facing to the front frame side is covered by a front louver 16 in which a plurality of vanes 17 extending in a horizontal direction while facing in a slant upward direction as seen from the front frame side are disposed while being spaced apart in a vertical direction so as to receive rain water coming from the air discharging port 2 in a slant direction with the vanes 17. |
