Construction machine

A construction machine comprising:

• a main body;
• a working device that is mounted on the main body;
• an engine that is provided in the main body;
• a cooling fan that is provided in the main body;
• and
• a post-treatment device that is provided in the main body, and purifies exhaust gas of the engine, the construction machine comprising:
• electric components that are disposed in the post-treatment device;
• a cover member that is provided above the post-treatment device, and covers the electric components;
• an inflow side opening that is provided in a first end of the cover member located on an upstream side of a flow of cooling air generated by the cooling fan, and allows the cooling air to flow therein;
• an inflow side guide section that smoothly guides the cooling air flowing in from the inflow side opening to inside of the cover member, and is provided in the cover member;
• an outflow side opening that is provided in a second end of the cover member located on a downstream side of the flow of the cooling air, and allows the cooling air flowing in from the inflow side opening to flow out;
• a support member that is fixed to a mounting member disposed in the post-treatment device;
• and
• a fixing section that fixes the cover member to the support member, wherein
• the cover member is formed such that the inflow side guide section expands toward the upstream side of the flow of the cooling air with respect to a space formed between the cover member and the post-treatment device, and having the electric components therein, and a space between the post-treatment device and the cover member is formed so as to narrow from the inflow side opening toward the outflow side opening.
