PROBLEM TO BE SOLVED: To prevent leakage of heated air and noise of an engine compartment to a driver's seat side by improving air-tightness of the engine compartment, and preventing inverse suction of the heated air in the engine compartment in cooling a radiator. SOLUTION: The revolving work machine 1 comprises the engine compartment 34 with an engine 23 transversely arranged provided on a rear part of a swivel base 4, a dividing wall 29 for partitioning the driver's seat 14 provided on a front side of the engine compartment 34, the radiator 25, a radiator fan 24, and a fan shroud 45 arranged on one side of left and right sides of the engine 23, a hydraulic pump 26 arranged on the other side of the left and right sides, a fixing cover 30 for covering a front part and an upper part of the engine compartment 34, and a rear part cover 31 for covering the rear part so as to be freely opened and closed. Partitioning walls 46, 47 are provided so as to project around the fan shroud 45. A partitioning member 48 is connected on an upper side of the partitioning wall 47 on an upper side of the fan shroud 45. Outer peripheral edges of the dividing walls 46, 47 and the partitioning member 48 come in contact with the fixing cover 30 and rear part cover 31 so as to be in a state for preventing fan wind from distributing.
