PROBLEM TO BE SOLVED: To improve a loading property of a load carrying platform floor on a vehicle by reducing the thickness of a floor frame block and restraining cost low by improving productivity. SOLUTION: The floor frame block 6 is constituted by integrally forming left and right vertical beams free to fasten on a side rail 1 extending in the longitudinal direction of a vehicle, an intermediate beam 3 connecting the vertical beams to each other and an outer receiver beam 4 projected toward the left and right sides of the vehicle from a side part of each of the vertical beams and setting a cross-section shape in accordance with a bending moment by light alloy casting, the load carrying platform floor 9 of prescribed length holding flexural strength is assembled by connecting a plurality of the adjacent floor frame blocks 6 to each other by upper side and lower side assembling bridging materials 7, 8 in a state of making end surfaces in the longitudinal direction of the floor frame blocks 6 contact with each other, the load carrying platform frame 9 is loaded on the side rail 1 and the vertical beam of each of the floor frame blocks 6 is fastened on the side rail 1.
