PROBLEM TO BE SOLVED: To install a dust-proof net without being influenced by an arrangement position of a heat exchanger and set a shape and a size of the dust-proof net without having any relation with the heat exchanger. SOLUTION: The dust-proof net 11 for use in removing dust contained in air sucked by a cooling fan 5 is installed at a forward location of a capacitor 9 positioned at the most upstream among several heat exchangers while being spaced apart from the capacitor 9 with respect to a flow of air sucked by the cooling fan 5 where there is provided a support means for supporting the dust-proof net 11 at a member for forming an engine chamber 2. The support means is arranged to enclose the upper, lower, right and left sides of the dust-proof net 11 and comprised of a first side holding plate 12 fixed to a front side partition cover 2a of the engine chamber 2, a second side holding plate 13 fixed to a rear side partition cover 2b of the engine chamber 2, a lower holding plate 14 fixed to a turning frame 1a and an upper holding plate 15 arranged at the upper part of the dust-proof net 11.
