摘要： A pair of supported portions are provided in a bifurcated manner on the base end of the boom of a work machine. Operation oil hoses for an arm cylinder and operation oil hoses for a bucket cylinder are guided and piped into the boom from between both the supported portions. A hose guide hole is provided below each of the boom support portions so that operation oil hoses for the boom cylinder are inserted into the respective hose guide holes. At an intermediate portion of the rear surface of the boom, the operation oil hoses are taken out from the inside of the boom through a hose attachment plate and connected to respective external hoses connected to the arm cylinder. At a tip end of the boom, the operation oil hoses are pulled out from the inside of the boom through a rear side inclined surface of an angle rib.
