PURPOSE:To suppress the pitching on a bed which is generated by the vibrating force due to the peculiar bending vibration of the chassis of a truck by supporting the front edge part of the bed which operates as the node of the peculiar vibration mode of the chassis, onto the chassis by a pin. CONSTITUTION:The front edge part of a bed 2 is supported onto a chassis 4 by a pin 9 which extends horizontally and laterally, and the rear side of the bed 2 is supported onto the chassis 4 by a plurality of springs 34. Said spring 34 is constituted of the connection of a rubber block 22 with the upper and lower brackets 20 and 21 in pairs, and the bracket 20 is fixed onto a subframe 5 by bolts, and the bracket 21 is fixed onto the chassis 4 by bolts. A lateral joist 12 connected to the bottom wall of the bed 2 is loaded onto the subframe 5 and fixed by bolts. |
