Patent attributes
A construction machine according to the present invention includes electric components 20 and a cover member 21, and includes an inflow side opening 25 that allows cooling air generated by the cooling fan 16 to flow therein, and an outflow side opening 26 that allows the cooling air flowing in from the inflow side opening 25 to flow out, in which the cover member 21 is formed such that the inflow side opening 25 expands toward an upstream side of a flow of the cooling air with respect to a space formed between the cover member 21 and the post-treatment device 17, and having the electric components 20 therein, and a space between the post-treatment device 17 and the cover member 21 narrows from the inflow side opening 25 toward the outflow side opening 26.
