PROBLEM TO BE SOLVED: To prevent a hydraulic hose from being a hindrance to operations and improve an appearance, by preventing the hydraulic hose from greatly protruding from a section between first and second booms, even in an ultrasmall revolving attitude. SOLUTION: In this backhoe, a device supporting base for pivotally supporting the first boom 33A and a boom cylinder is provided on a revolving base 7, and a control valve for controlling the boom cylinder, an offset cylinder 40, an arm cylinder and a working-implement cylinder is arranged on the revolving cylinder 7. The hydraulic hoses 73, 74 and 75, which lead to the offset cylinder, the arm cylinder and the working-implement cylinder from the control valve, are separated into two groups in the first boom, passed to both the right and left sides of a pivot 47 for pivotally supporting a second boom, and inserted into the second boom from a leading end of the first boom.
