PROBLEM TO BE SOLVED: To protect a hose in the vicinity of a mouthpiece and enhance the durability and reliability thereof by connecting each hose between the hose and the mouthpiece and providing a hose clamp. SOLUTION: A plurality of hoses 17 are disposed between an upper revolving body 2 and a boom 8 to be mutually parallel in the right and left sides. A hose clamp 19 connecting respective hoses 17 and extending to the right and left sides is provided in one end side 17A of the hose 17 and the mouthpiece 18. The hose clamp 19 is constituted of a pair of elastic holding members 20 pinching respective hoses and metallic clampimg plates 21, 22 enhancing the rigidity of the hose clamp 19 to the right and left directions, and the like. In this way, when the boom 8 rises and falls, the elastic holding member 20 is warped together with respective hoses 17 to protect the hose 17 in the vicinity of the mouthpiece 18. Further, respective hoses 17 are prevented from laterally warping by the clamping plates 21, 22.
