PROBLEM TO BE SOLVED: To set a reserve tank of a construction machine at a position higher than an upper tank of a radiator while reducing the influence of heat generated from an engine.SOLUTION: A construction machine 1 comprises: an undercarriage 2; a revolving superstructure 4 turnably mounted on the undercarriage; and a work device 5 with one end attached to the revolving superstructure. The revolving superstructure comprises: an engine 9; a radiator 30 that exchanges heat with a coolant for cooling the engine; a cooling fan 10 that supplies cooling air to the radiator; and a reserve tank 12 that stores the coolant to be fed to the radiator. A shroud 11 is provided for covering the periphery of the cooling fan so as to partition the engine and the radiator, and a reserve tank chamber 13 for holding the reserve tank is formed on an upper corner part of the shroud. The reserve tank chamber thermally partitions a machine chamber part where the engine is arranged. The reserve tank chamber further includes an opening 13B on the side of a radiator chamber 35 where the radiator is arranged. |
