PROBLEM TO BE SOLVED: To improve comfortableness by improving the pitching and rolling of a cab without reducing the damping performance of the vibrations transmitted to the cab from a chassis. SOLUTION: The rear end of a link lever 3 inclined backward and downward from the front section of the chassis is pivotally fitted to the front lower face of the cab 4. The front section of the cab 4 is connected to the chassis 1 via an air spring 6 between the middle section of the link lever 3 and the cab 4. The pitching and rolling of the cab 4 are suppressed to improve comfortableness by connecting the rear section of the cab 4 to the chassis 1 via a pair of air springs 7 inclined upward and outward.
