PROBLEM TO BE SOLVED: To inhibit a plurality of hydraulic hoses, provided between a cab and a vehicle body, from being forcedly bent along with the ascending/descending motion of the cab.SOLUTION: A parallel link 22 constituting a cab hoisting/lowering apparatus 11 is provided with a clamp guide device 39 which comprises a supporting frame body 41 and a frame body swing mechanism 42; and a hose clamp 45, which binds midway portions of the plurality of hydraulic hoses 38, is movably housed in the supporting frame body 41. Thus, the hose clamp 45 can inhibit the respective hydraulic hoses 38 from rubbing against each other along with the ascending/descending motion of the cab 9. Additionally, the hose clamp 45 can move in the supporting frame body 41 depending on the motion of the parallel link 22, so as to inhibit the forced bending of the respective hydraulic hoses 38 and prolong the lives of the respective hydraulic hoses 38. |
