<p>A freight-vehicle deck structure is achieved which is provided with: a deck floor panel (7) for having cargo loaded thereon; a cross member (6) which traverses between left and right side frames (4), and which is connected by a mounting member (9); and a sill cross (8) which is connected to the cross member (6), and which supports the floor panel (7). An upper surface (8d) of the sill cross (8) is formed into a stepped shape having a plurality of steps (8da, 8db, 8dc) which descend step-by-step towards the inside of the vehicle in the width direction. Spot welding is used to connect, at respective welding points (S1, S2, S3), the floor panel (7) to at least two of the plurality of steps (8da, 8db, 8dc) of the sill cross (8). The welding points (S1, S2, S3) corresponding to the at least two steps are disposed at three dimensionally equal distances from the mounting member (9).</p> |
