PROBLEM TO BE SOLVED: To prevent a hose from projecting a great deal from a front by providing the front with a hose guide. SOLUTION: The tip side of the front 8 is provided with a grapple 11 driven by an attachment driving cylinder 15. Each hose 27 for the cylinder 15 is arranged flexurally deformed to straddle piping 20 for cylinders 13, 14 and connected to piping 21, 25 by a rotary joint 22 and a bent joint 26. An upper face part 9A of a boom 9 is provided with the hose guide 28, and the hose 27 is guided by a guide roller 32 so as to be pressed to the boom 9 side. Consequently, when the front 8 moves downward, the hose 27 can be held in a lower position than a cab 5, and conveying work or the like of a vehicle can be smoothly performed. When the front 8 moves upward, hose 27 can be prevented from interfering with an on-vehicle structure or the like on the rear side of the front 8. COPYRIGHT: (C)2005,JPO&NCIPI
