Abstract: PROBLEM TO BE SOLVED: To dispense with a drain pipe line from a running drive device to a tank, simplify and miniaturize the construction of a center joint, and simplify piping constitution around the center joint. SOLUTION: When a direction changeover valve 8 is operated for letting pressure oil from a hydraulic pump 6 flow in a first connection pipe line 9, the pressure oil from the direction changeover valve 8 flows in a feed/discharge line 14 in a running drive device 5 through a center joint 11 and a second connection pipe line 12 so as to be fed to a running motor 16, and the pressure oil discharged from the running motor 16 is discharged to a tank 18 through a feed/discharge line 15, a second connection pipe line 13, the center joint 11, a first connection pipe line 10, the direction changeover valve 8, and a tank pipe line 17.  Drain oil leaked from the running motor 16 flows in a communication line 22 through a drain circuit 19, and when the pressure becomes over the spring force of a check valve 4 connected to the feed/discharge line 15 on the low pressure side, the check valve 24 is opened, the oil flows in the feed/discharge line 15 and discharges into the tank 18.
