PURPOSE: To prevent visibility from being impaired by lowering down an eye line of an operator, by vertically movably providing a cab device for protecting a driver's seat relating to the main unit of a road work construction machine. ;CONSTITUTION: A right/left directional running rail 11 is provided in a rear end upper surface of a machine body frame 10 in a running machine body, to fit a running roller 14a of a running mount 14 to a fitting groove 11a of this rail 11, and a supporting shaft 12a of a supporting member 12 in a cab 13 is supported by a supporting pipe 14b of the running mount 14. This supporting member 12 can be,right/left moved by an oil hydraulic motor, drive pulley and an operating belt, and the cab 13, fitting its guide roller 24 to a lift rail 25 of the supporting member 12, is vertically moved relating to the supporting member 12 by extending/contracting a hydraulic cylinder 26, in a right/left directional prescribed position of the cab 13. Accordingly, a cab device is placed in a lifted position to obtain a wide visual field during work and in a low position to obtain convenience for transport during carrying by a carrier vehicle, and workability can be improved.;COPYRIGHT: (C)1995,JPO
