PROBLEM TO BE SOLVED: To provide an adequate tilt operational force by controlling torsional stress accumulated in a torsion bar responsive to a tilt angle of a cab in a tilt device for the cab. SOLUTION: This device is provided with guide members 10a, 10b that are arranged at application point parts of tilt forces of torsion bar arms 8a, 8b connected with torsion bars 7a, 7b, and control the tilt forces by moving the application point following a tilt operation. These guide members 10a, 10b are constituted in shapes where the tilt forces by the torsion bars 7a, 7b for the tilt angle of the cab become larger than a relation that the tilt forces by the torsion bars 7a, 7b change inversely proportionally to the tilt angle. |
