A hydraulic hose 16 bent in a curved manner along the vertical swing direction plane of the boom 5 is connected to the pressure oil relay section 15 provided in the vicinity of the connection section with the boom 5, and
The relay part 15 and a pressure oil terminal 17 disposed on the top surface of the boom 5 are connected to each other by a fixed pipe body 18, and a hydraulic hose 19 for the boom cylinder, which is connected to the pressure oil terminal 17, and a hydraulic hose 19 for the bucket cylinder and the arm. Each hydraulic hose 20 for the cylinder,
All hydraulic hoses such as No. 21 are arranged horizontally in parallel on the upper surface of the boom 5, and these parallel hydraulic hose groups H are routed to the swivel base 2 side through the internal space 23 of the swing bracket 3, and are connected to the inside of the swing bracket 3. The hydraulic piping structure of a backhoe has the hydraulic hose group H positioned and fixed to this bracket 3 by a clamp mechanism C1 .
