PROBLEM TO BE SOLVED: To reduce the number of part items, vehicle weight and cost by enhancing ride comfort by damping a vibration transmitted from a chassis frame to a cab and by damping a yawing and a rolling of the cab by a friction between plates while it is resiliently restricted by a resilient deformation of a lamella spring device. SOLUTION: A lamella spring device 3 is provided on a suspension device. In the lamella spring device 3, a pair of lamella spring 10 integrally formed by superposing a roller 2 turnably mounted to a projection 5 hung and fixed to a lower portion 4a of a cab 4 and a plurality of spring plates 6, 8, 9 respectively are mounted to a chassis frame 11 side by tightening members 12, 13 in the vertical state in the state that they are left by an outer diameter degree of a roller 2. A pair of lamella spring 10 are positioned at both right and left sides of the roller 2 at the time of non-tilting and a motion of the cab 4 in a right/left direction is restricted. |
