PURPOSE:To obtain a loading case floor easily manufactured, light in its weight and at low cost, by forming a floor plate or reinforcement plate piled on said floor plate partially or totally into a curved surface and arranging a pair of main beams parallelly extending with each other in a longitudinal direction with a distance apart on rear of the curved plate. CONSTITUTION:A loading case 2 is mounted up-down movably onto the center of a pivotal support part 3 on a chassis 1, and constututed by a side swing door 4, rear swing door 5 and floor plate 6. Here the floor plate 6 is formed into a flat plate shape, and to its rear face a reinforcement plate 7 curved in an arc pattern upward is piled. While on the rear face of the reinforcement plate 7, a pair of main beams 8 parallelly extending with each other are longitudinally arranged with a distance apart and placed on a chassis frame 11 through a support wood 9 and subframe 10. In this way, reinforcement members such as cross members, outriggers and the like can be completely eliminated or remarkably decreased thus capable of reducing a labor cost as compared with that where conventional main beams, cross members and outriggers are separately constructed. |
