PROBLEM TO BE SOLVED: To increase the durability of a fuel tank or the like and improve the sucking characteristics of a hydraulic oil by a hydraulic pump by suppressing a force applied to the fuel tank or the like by the sloshing behavior of fuel. SOLUTION: A hydraulic oil tank 18 is placed on a fuel tank 14 which is placed on a slewing frame 6 and has a height dimension smaller than that of a building cover 9. Therefore, the fuel tank 14 is formed in a shape extending in the longitudinal direction, the space between the upper surface plate 14a of the fuel tank 14 and the level of the fuel is reduced, and the center of gravity of the fuel tank 14 is reduced. Also, since the hydraulic oil tank 18 is placed on the fuel tank 14, the position of the hydraulic oil tank 18 is raised, a suction pipe 24 is formed in an arcuate shape, and the suction characteristics of the hydraulic oil by a hydraulic pump 8 are improved.
