PROBLEM TO BE SOLVED: To simplify connection work, replacement work, inspection work and maintenance work of a pipe, while preventing damage of the pipe, in a lower traveling body of a construction machine.SOLUTION: A lower traveling body 1 comprises a pair of axles 14 separately arranged in front and in rear of a turning body support part 12, a pair of crawler devices 6 separately arranged on both sides of the turning body support part 12, extending so as to project to the front and rear of the pair of axles 14 and supported by the pair of axles 14 so as to be movable in the width direction of the lower traveling body 1, a flexible hydraulic pipe 8 for supplying hydraulic pressure to the respective crawler devices 6 and a regulating member 9 for regulating the movement of the hydraulic pipe 8. The hydraulic pipe 8 extends to the turning body support part 12 by passing through on the rear side axle 14 from a rear end part of the respective crawler devices 6, and the regulating member 9 is provided on an upper surface of the rear side axle 14, and limits a moving range of the hydraulic pipe 8 to a specific range in response to the fact that the respective crawler devices 6 move in the width direction of the lower traveling body 1. |
