To hinder deformation of an area of a vehicle cabin in which a passenger rides, if extreme impact load is input in the event of a full-lap collision.SOLUTION: A vehicle cabin structure 100 comprises: a dash panel 10; a floor panel 20; and a floor tunnel member 25 disposed in the middle, in a vehicle width direction, of the floor panel 20, a cross-section of which has an upward projecting groove, and a front end of which is connected to the dash panel 10 and extending in vehicle forward and backward directions. The floor tunnel member 25 has in a front-end part a rigidity decreased part 26 rigidity of which in the vehicle forward and backward directions is lower than rigidity of a central portion 28 in the vehicle forward and backward directions.SELECTED DRAWING: Figure 1
【課題】フルラップ衝突で過大な衝撃荷重が入力された際に、車室内の乗員が搭乗するエリアの変形を抑制する。【解決手段】ダッシュパネル10と、フロアパネル20と、フロアパネル20の車両幅方向中央に配置され、上に凸の溝形断面で前端がダッシュパネル10に接続されて車両前後方向に延びるフロアトンネルメンバ25と、を有する車室構造100であって、フロアトンネルメンバ25は、前端部に車両前後方向の剛性が中央部分28の車両前後方向の剛性よりも小さい剛性低下部26を有する。【選択図】図1
