<P>PROBLEM TO BE SOLVED: To prevent clogging caused by dust without a big structure change and enabling efficient cleaning work without detaching a heat exchanger from a vehicle. Ž<P>SOLUTION: A cooling device comprises a fan 2 provided on an engine 1 and guiding air to a plurality of heat exchangers from an engine side, a fan shroud 3 installed at a downstream of the fan 2 for guiding air, an oil cooler 4 and a radiator 5 arranged at a downstream of the fan shroud 3. Both sides of the plurality of heat exchangers are covered by a pair of U-shaped frames 6, 6. The frame 6 is fixed on the shroud 3 by an upstream side bent piece 6a opposing a dust proof net 9. A notch 3b formed by cutting an upper surface part of the fan shroud 3 by a width and thickness of the dust proof net 9 from a downstream side is received by the dust proof net 9 as an insertion opening. The bent piece 6a is projected inside from both ends of the notches 3b and the dust proof net 9 is supported from a downstream side by the projection 6b. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
