description In a construction machine, a boom assist cylinder (7A) assists an operation of a boom (4) by a hydraulic pressure, and an arm assist cylinder (8A) assists an operation of an arm (5) by a hydraulic pressure. An accumulator (16) accumulates operation oil to be supplied to the boom assist cylinder and the arm assist cylinder in a pressurized state. A first hydraulic pipe (14) connects between the boom assist cylinder and the arm assist cylinder. A second hydraulic pipe (12) connects between the arm assist cylinder and the accumulator. The second hydraulic pipe is connected to a hydraulic connection port of the arm assist cylinder so that the operation oil is supplied in a direction of closing the arm from the accumulator to the arm assist cylinder.
