PROBLEM TO BE SOLVED: To enable reliable transmission of a force to a floor tunnel by reliably moving a cross member downward during a side collision even with a vehicle in which the cross member is located above a floor surface.SOLUTION: A planar fitting part 5b extending in a horizontal direction which is a direction of a floor tunnel 7 is formed on a top face of a cross member body 5a and at an end part on a floor tunnel 2 side. The fitting part 5b is coupled to a top face of a raising member 10 at a position above a center line of the cross member body 5a in a vehicle width direction. Thus, the fitting part 5b is deformed downward at a boundary portion with the cross member body 5a by an impact of a side collision, and a force can be reliably transmitted to the floor tunnel 7 by moving a cross member 5 toward the direction of the floor tunnel 7.SELECTED DRAWING: Figure 1

    【課題】クロスメンバがフロア面よりも上方に位置する車両であっても、側突時にクロスメンバを確実に下向きに移動させてフロアトンネルに確実に力を伝達できるようにする。【解決手段】クロスメンバ本体5aの上面であってフロアトンネル2側の端部に、フロアトンネル7の方向である水平方向に延出して平面状の取付部5bを形成し、この取付部5bをクロスメンバ本体5aの車幅方向の中心線より上の位置で嵩上げ部材10の上面に結合する。そのため、側突時の衝撃によって、取付部5bがクロスメンバ本体5aとの境界部分において下向きに変形し、クロスメンバ5をフロアトンネル7の方向に向かって確実に移動させてフロアトンネル7に確実に力を伝達することが可能になる。【選択図】図1
