PROBLEM TO BE SOLVED: To provide a module structure of a load-carrying platform floor capable of reducing the thickness of a floor skeleton and keeping rigidity. SOLUTION: This module structure is provided with the floor skeleton 6 forming left and right vertical through beams 2 extending in the longitudinal direction of a vehicle and tightened to a side rail 1, a plurality of intermediate beams 3 for connecting side parts of each vertical through beam 2, and a plurality of outer receiving beams 4 protruding from the side part of each vertical through beam 2 toward a side of the vehicle and setting a cross sectional shape by matching with bending moment integrally by aluminum alloy casting to arrange the floor skeletons 6 in the longitudinal direction of the vehicle and support a floor member of a flat type load-carrying platform and a box-shaped load-carrying platform. That is, the intermediate beams 3 and the outer receiving beams 4 are continuous with the side parts of the vertical through beams 2 to reduce thickness of the floor skeleton 5 and reduce height of the load-carrying platform floor. By forming the vertical through beams 2, the intermediate beams 3, and the outer receiving beams 4 integrally by aluminum alloy, rigidity of the whole floor skeleton 6 is increased.
