<p>PROBLEM TO BE SOLVED: To provide a gate structure which can facilitate fitting and maintenance for a hinge from a user friendly viewpoint such as easiness of maintenance work for confirming looseness of a connecting member and no damage to a cargo, and has excellent strength, and which makes the load-carrying platform side surface of a gate substantially flat. SOLUTION: In this gate structure 1, a hollow part 3 of a panel 2 formed by a hollow extrusion material is fastened to the hinge 5 by fixing nuts 4b, 4b' fitted from the load-carrying platform side of the hollow part 3 and fixing bolts 4a, 4a' fitted from an outer wall side of the hollow part 3. The surface on the load-carrying platform side of the hollow part 3 to be fastened is provided with groove parts 6, 6 positioned corresponding to the fixing nuts 4b, 4b', and the groove parts 6, 6 are formed to have such a width W as to insert the heads 7 of the fixing nuts 4b, 4b' and a depth D larger than the thickness of the heads 7 of the fixing nuts 4b, 4b', thereby solving the above problem.</p> |
