PROBLEM TO BE SOLVED: To provide a main sill, an understructure of a truck loading space and a truck capable of selecting the existence of a spacer and a cross sill.SOLUTION: A main sill 30 of the present invention is a main sill interposed between a chassis frame 20 of a truck and a floor board 40, and comprises a cross-sectional rectangular lower end part 31 for contacting with the chassis frame or a spacer 60 on its undersurface, a vertical plate part 32 extending upward from an upper surface of the lower end part and a horizontal plate part 33 for contacting with the floor board or a cross sill by extending in the lateral direction from the upper end of the vertical plate part, and an opening part 34 extending in the longitudinal direction is formed on the undersurface of the lower end part, and a groove part 38 for fitting a bolt or a nut is formed on a side surface of the vertical plate part. When the spacer is not used, the lower end part is directly placed on the chassis frame, and a head of a rivet exposed from the upper surface of the chassis frame is preferably stored in the opening part. The main sill and the chassis frame can be joined by fastening a connection plate by the bolt by using the groove part.SELECTED DRAWING: Figure 1

    【課題】 スペーサ及び横根太の有無を選択できる縦根太、トラック荷台の下部構造及びトラックを提供する。【解決手段】 本発明の縦根太30は、トラックのシャーシフレーム20と床板40との間に介在する縦根太において、その下面においてシャーシフレーム又はスペーサ60と接触する断面矩形状の下端部31と、下端部の上面から上方にのびる垂直平板部32と、垂直平板部の上端から左右方向にのびて前記床板又は横根太と接触する水平平板部33とを備えており、下端部の下面には長手方向にのびる開口部34が形成され、垂直平板部の側面にはボルト又はナットを嵌め込むための溝部38が形成されている。スペーサを使用しない場合にはシャーシフレームの上に下端部を直接載置し、シャーシフレームの上面から露出するリベットの頭等を開口部内に収容すればよい。また、溝部を使用して連結プレートをボルト締めすることで縦根太とシャーシフレームを接合できる。【選択図】図1
