Zusammenfassung: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. 【課題】ピンシリンダ配管の配索構造を工夫して作業性、耐久性の向上を図る。【解決手段】クローラ３０が取り外し可能に設けられている。下部走行体２は、クローラ３０をカーボディ１０に結合するピン結合装置２０を備える。ピン結合装置２０は、ピンシリンダ２４と油圧ホース６０が着脱可能に連結される連結器２６Ｆ，２６Ｒとを接続するピンシリンダ配管２５Ｆ，２５Ｒを有している。ピンシリンダ配管２５Ｆ，２５Ｒが、クローラ３０の内側部に沿って配索され、クローラ側結合プレート２１に形成された切欠部６５を通り抜けることにより、連結器２６Ｆ，２６Ｒが、クローラ側結合プレート２１の外側に位置している。【選択図】図５
