PROBLEM TO BE SOLVED: To provide a work machine for improving its workability and durability by devising the laying structure of each pin cylinder pipe.SOLUTION: An undercarriage 2 where crawlers 30 are removably provided includes pin coupling devices 20 for coupling the crawlers 30 with a car body 10, respectively. The pin coupling devices 20 each have pin cylinder pipes 25F, 25R for connecting a pin cylinder 24 and connectors 26F, 26R to which a hydraulic hose 60 is detachably connected. The pin cylinder pipes 25F, 25R are laid along the inside part of each crawler 30 while passing through a cutout part 65 of a crawler side coupling plate 21, so that the connectors 26F, 26R are located outside the crawler side coupling plate 21. |
