PROBLEM TO BE SOLVED: To strike a balance between the improvement of cargo bed durability for extending the durability life of a cargo bed and the securement of the cargo bed connection stability for suppressing the deflection of the cargo bed.SOLUTION: A semi-trailer truck cargo bed mounting structure A is provided for mounting a cargo bed 2 on an upper surface of a pair of chassis frames 1 disposed while being extended in the vehicle fore-and-aft direction of a truck. The structure includes a cargo bed elastic support structure A1 and a displacement control connecting structure A2. The cargo bed elastic support structure A1 is set between the cargo bed 2 and the chassis frame 1, and elastically supports the cargo bed 2 to the chassis frame 1. The displacement control connection structure A2 is set in parallel with the cargo bed elastic support structure A1. The cargo bed 2 is connected with the chassis frame 1 to each other, while controlling relative displacement except the vertical direction of the vehicle by allowing the relative displacement of the vehicle in the vertical direction among the relative displacement caused by the elastic support between the cargo bed 2 and the chassis frame 1. |
