PROBLEM TO BE SOLVED: To improve a construction machine in terms of cleaning of a cooling device, reduction of temperature rise in an engine room, reduction of noise leakage and downsizing by providing a partition member in the engine room loaded to the construction machine. SOLUTION: The construction machine is equipped with parallelly arranged two cooling devices R, and opening 50 for distributing cooling air to an engine front cover C1 of the engine room 12, a partition member 60 for forming a cooling air distribution passage CD between the engine cover C1 and the partition member 60. A cooling air duct for cooling the engine room 12 and an engine 22 by ventilating atmospheric fluid in the engine room 12 by generating negative pressure at a ventilation opening CE2 of a cooling air ventilation passage CDE2 with cooling air flowing through a cooling air introducing passage CD1 between the engine front cover C1 and the partition member 60 is structured.
