The invention provides a vehicle body floor structure capable of properly preventing distortion and deformation of a floor part. A vehicle body floor structure (1) is provided with: a lower wall section (13) and a main body section (21), which are floor sections spanning between a pair of lower side members in the vehicle width direction; and an upper wall section (11) and side wall sections (12, 12) as a tunnel section that extends in the front-rear direction at the middle section of the floor section in the vehicle width direction and has an upward convex shape, and a plurality of first ridge lines (81a, 81b, 82a, 82b) that extend in the vehicle width direction from a boundary section between the floor section and the tunnel section are formed on the floor section. The plurality of first ridge lines (81a, 81b, 82a, 82b) are inclined so as to tend to the front as the first ridge lines tend to the outside in the vehicle width direction.

    本发明提供能够恰当防止地板部的歪曲以及变形的车身地板构造。车身地板构造(1)具有:作为架设于车宽方向上的一对下纵梁之间的地板部的下壁部(13)以及主体部(21);和作为在地板部的车宽方向中间部处沿前后方向延伸并向上呈凸形状的通道部的上壁部(11)以及侧壁部(12、12),在地板部形成有从与通道部之间的边界部沿车宽方向延伸的多条第一棱线(81a、81b、82a、82b),多条第一棱线(81a、81b、82a、82b)以随着趋向车宽方向外侧而趋向前方的方式倾斜。
