To reduce the weight of a floor panel while suppressing the distortion of the floor panel when a load is applied to the floor panel from an upper side.SOLUTION: A vehicular floor structure includes: a floor member 70 provided with an opening 72; and a floor panel 10 that covers the opening 72. The floor panel 10 is formed by arranging plural kinds of unit panels 12a to 12f each in a rectangular shape as viewed from the upper side of a vehicle in a shorter-side direction side by side and integrating those. The two end sides of the floor panel 10 along a direction (X-direction) in which the respective unit panels 12a to 12f are arranged side by side, and the side of at least one (12f) of the two unit panels 12a and 12f arranged side by side at respective ends of the floor panel 10 are supported by respective support portions 80 and 82 of the floor member 70. The unit panel 12f having the side supported by the support portion 82 of the floor member 70 has a lighter weight per a unit area in comparison with the other unit panels 12c, 12d, and 12e each having a longer length in the shorter-side direction than the length of the supported unit panel in the shorter-side direction.SELECTED DRAWING: Figure 3
【課題】フロアパネルの上から荷重が印加された際のフロアパネルの撓みを抑制しつつ、フロアパネルの重量を低減する。【解決手段】車両のフロア構造は、開口72が形成されたフロア部材70と、開口72を覆うフロアパネル10とを含む。フロアパネル10は、車両上面視で長方形の複数種類の単位パネル12a~12fを、その短手方向に順次並べ一体化して構成され、フロアパネル10の、各単位パネル12a~12fが並ぶ方向(X方向)に沿った2つの端辺と、フロアパネル10の両端に並べられた2つの単位パネル12a,12fのうちの少なくとも1つ(12f)の側辺とが、フロア部材70の支持部80,82に支持される。フロア部材70の支持部82に側辺が支持される単位パネル12fは、その短手方向の長さ以上の短手方向の長さを有する他の単位パネル12c,12d,12eに比べて、単位面積あたりの重量が軽い。【選択図】図3
