PROBLEM TO BE SOLVED: To provide a freight-vehicle deck structure that suppresses occurrence of cracking due to an external force in a peeling direction at spot welding points of a deck floor panel to a sill cross of a cross member end part without using a conventional reinforcing plate or the like.SOLUTION: A freight-vehicle deck structure is configured as follows. Step-shaped parts are provided at a flange 8d of a sill cross 8. First to third spot welding points S1, S2 and S3 at respective step parts 8da, 8db and 8dc are three-dimensionally disposed at equal intervals from a mounting member 9 so as to equally and dispersedly receive an external force in a peeling direction inputted from the mounting member 9. |
