To inhibit permanent deformation of a side panel by softly receiving an external input imposed on the side panel when the external input is an excess load or impact force, and upgrade the durability of a cargo bed.SOLUTION: Provided is a cargo bed structure of a truck having a floor panel 21 and left and right side panels 22, 22 having external surfaces to which side panel reinforcement frames 7 are fixed, with respect to a cargo bed 2 shaped like a box and having a top surface opened. The side panel 22 has a curved panel part 22d, an angle of which is gradually changed from a lengthwise direction to a sideways direction, in an area intersecting the floor panel 21. The side panel reinforcement frame 7 includes an upper end reinforcement frame 71 and a lengthwise reinforcement frame 72. The lengthwise reinforcement frame 72 includes a first bent frame reinforcement part 72b fixed to an area ranging from a position of an undersurface of the upper end reinforcement frame 71 to a position ahead of the curved panel part 22d, and a curved plate reinforcement part 72d formed with a curved plate to be fixed to an area of the curved panel part 22d in a close contact manner.SELECTED DRAWING: Figure 3
【課題】サイドパネルへ加わる外部入力が過大荷重や衝撃力であるとき、これを柔軟に受け止めてサイドパネルの永久変形を抑制し、荷台耐久性の向上を図ること。【解決手段】上面が開放された箱形状による荷台2であって、床パネル21と、パネル外面にサイドパネル補強枠7が固定される左右のサイドパネル22,22とを有するトラックの荷台構造である。サイドパネル22は、床パネル21と交わる領域に、縦方向から横方向へと徐々に角度変化させた湾曲パネル部22dを有する。サイドパネル補強枠7は、上端補強枠71と、縦方向補強枠72と、を備える。縦方向補強枠72は、上端補強枠71の下面位置から湾曲パネル部22dより前までの領域に固定される第1屈曲枠補強部72bと、湾曲パネル部22dの領域に密着状態で固定される湾曲平板による湾曲プレート補強部72dと、を有する。【選択図】図3
