PURPOSE:To maintain the comfortable amenity of a cabin by providing a coupler by which an oil-pressure pipe through which high-pressure oil in a control valve is flowed-in is detachably fitted to the outside of the cabin. CONSTITUTION:A fitting port 13b piercing the inside and outside portions is provided in the cabin front cover 13a of a cabin 13, and a lever 16 projected from a control valve 14 for working machine is provided near a driving car in the cabin 13 through the fitting port 13b. A coupler 14f by which an oil-pressure pipe 14e through which high-pressure oil in the oil path of the control valve 14 is flowed in or out is attached or detached and an oil-pressure pipe 14b are provided on the outside of the cabin 13. Since the oil-pressure pipe 14e can be attached or detached outside of the cabin 13, no contamination occurs in the cabin 13 even when oil leaks during the attachment or detachment of the oil-pressure pipe 14e, and therefore, comfortable amenity of the cabin 13 can be maintained. |
