PROBLEM TO BE SOLVED: To improve working easiness in assembling a cab, and the working environment of the cab, etc. by suppressing the vibration of a floor board using a simple constitution. SOLUTION: Under the floor board 14, a reinforcing member 16 is installed all over a gap between bolts 17 for fastening three members together located apart in the fore-and-aft direction, wherein the reinforcing member 16 is arranged to fastens a base frame 12 together with the floor board 14 using the bolts. Thereby the reinforcing member 16 can suppress the vibration of the central part of the floor board 14, for example without adding another vibrationproof mount separately from the vibrationproof mounts 23 at four corners, which can enhance the working effectiveness of operation to mount a cab 11 to a revolving frame 5. It is also possible to improve the working environment of an operator to perform operation in seating himself/herself on a driver seat 19. COPYRIGHT: (C)2006,JPO&NCIPI
