PROBLEM TO BE SOLVED: To prevent a deformation of an open hole for a wiring harness without causing problems such as a cost rise or a weight increase, and thereby to provide a vehicle floor structure with which the breakage or compression of the wiring harness can be prevented.SOLUTION: At the center part of a vehicle width direction, a mountain-shaped tunnel part 10 is formed extending in a vehicle longitudinal direction from a dash panel 3g till a vertical wall part 3n of a seat fitting bench 3j. At the front end part of the tunnel part 10, an inclined wall 10c inclining obliquely upward is provided, and a through-hole 10d for inserting a wiring harness 11 is provided in an upper wall 10a. Also, a reinforcement plate 12 covering the periphery of the through-hole 10d of the upper wall 10a is fixed to the upper wall 10a, and the end part 12b of the reinforcement plate 12 is positioned near the lower end part 3n' of the vertical wall part 3n of the seat fitting bench 3j.

    【課題】コスト上昇や重量増大の問題を招くことなくワイヤハーネス用貫通孔の変形を防止し、もってワイヤハーネスの断線あるいは圧迫を防止できる自動車のフロア構造を提供する。【解決手段】車幅方向中央部にダッシュパネル3gからシート取付け座3jの縦壁部3nまで車両前後方向に延びる山形状のトンネル部10が形成され、該トンネル部10の、前端部に斜め上方に傾斜する傾斜壁10cを設け、上壁10aにワイヤハーネス11を挿通させる貫通孔10dを形成し、該上壁10aの貫通孔10d周辺を覆う補強板12を該上壁10aに固定し、該補強板12の後端部12bを前記シート取付け座3jの縦壁部3nの下端部3n′付近に位置させた。【選択図】図4
