The invention relates to a floor tunnel laid along the vehicle front-rear direction on the floor surface of a passenger compartment, extending substantially linearly along the vehicle front-rear direction, and having a front end and a rear end. The cross section of the floor tunnel perpendicular to the vehicle front-rear direction has a hat-shaped open cross-sectional shape protruding from the floor surface. The floor tunnel is provided with a front-end area that has the front end and a main area that has the rear end and is continuous with the front-end area. The boundary position between the front-end area and the main area is within the range between a position of 30 mm from the front end toward the rear end and a position L/5 from the front end toward the rear end, where L (mm) is the total length from the front end to the rear end. Furthermore, the yield strength of the front-end area is lower than the yield strength of the main area.

    本发明涉及一种地板通道,沿着车辆前后方向铺设于车厢内的地面,沿着上述车辆前后方向大致直线状地延伸且具有前端以及后端,与上述车辆前后方向垂直的截面具有比上述地面突出的帽形的开放截面形状。该地板通道具备:前端区域,具有上述前端;以及主区域,具有上述后端且与上述前端区域相连。当将从上述前端到上述后端为止的全长设为L(mm)时,上述前端区域与上述主区域之间的边界位置处于从上述前端朝向上述后端为30mm的位置与从上述前端朝向上述后端为L/5的位置之间的范围内。并且,上述前端区域的屈服强度低于上述主区域的屈服强度。
