Abstract
A construction machine includes: an engine room provided with an intake opening and a discharge opening; a fan for sucking cooling air into the engine room through the intake opening; a duct provided in the engine room so as to communicate with the discharge opening and discharging the cooling air sucked into the engine room to an outside of the engine room through the discharge opening; and an exhaust gas pipe guiding exhaust gas discharged from the engine into the duct. A portion on a distal end side of the exhaust gas pipe is inserted into the duct, and the inserted portion of the exhaust gas pipe inserted into the duct is formed with an exhaust hole which causes the exhaust gas to be discharged in a direction different from a flowing direction of discharge wind in the duct through the exhaust hole.
