PROBLEM TO BE SOLVED: To provide a power device for a construction machine capable of stably operate work apparatus such as a work attachment or the like while reducing energy loss by restricting pressure loss. SOLUTION: A hydraulic pump and a motor are provided for each of a plurality of actuator, and the hydraulic pump is rotated by the motor to supply pressure oil to the actuator. In this case, a plurality of hydraulic pumps 20, 22, 24, motors 19, 21, 23 and hydraulic fluid tank 25 are gathered closely to each other, and gathered hydraulic pumps, motors, and hydraulic fluid tank are arranged at the positions on a slewing frame 10 in such a manner that the length of the hydraulic pipeline from the hydraulic pumps 20, 22, 24 to the actuator becomes short.
