PROBLEM TO BE SOLVED: To provide a working vehicle which can eliminate the clogging of a dust preventive cover by making dust and dirt adsorbed to the dustproof cover by an air stream for cooling an engine drop by the own weights. SOLUTION: An opening/closing part 16 for which a plurality of opening/closing plates 21 are freely swingably arranged, and a driving device 17 which swings the opening/closing plates 21 are arranged on the dustproof cover 13 to cover the opening part 7a of an engine cover 7. A channel of air which is sucked into an engine room through a suction port 12 on the dustparoof cover 13 is shut off by swinging the opening/closing plate 21 by the driving device 17. By the stream of the sucked in air, the adsorbing force for dust and dirt adsorbed by the dustproof cover 13 is eliminated, and dust and dirt adsorbed by the dustproof cover 13 are made to drop by the own weights, and the clogging of the dustproof cover 13 is eliminated.
