To effectively transfer a load applied from the upper side of a roof panel downward.SOLUTION: A reinforcement 12 extends in the vertical direction in the vicinity of the rear end of a roof side-plate portion 3b. The upper end portion is fixed with an energy absorptive member 14. The reinforcement 12 is formed into a closed cross-sectional shape and fixed to an inner side surface 7 in the vehicle width direction of the roof side-plate portion 3b. The lower end portion of the reinforcement 12 is supported at a rail portion of the body from below. An upper end 34 of the reinforcement 12 is disposed at a predetermined height position away from a roof upper-plate portion 3a downward. A roof support plate portion 21f of the energy absorptive member 14 is disposed above the upper end 34 of the reinforcement 12 and supports the roof upper-plate portion 3a from below. The energy absorptive member 14 is formed into a hat-shaped cross-section that is more easily deformed than the reinforcement 12 with respect to the load from above, extends in the vertical direction, and deforms by the input of a load from above to absorb the energy.SELECTED DRAWING: Figure 6

    【課題】ルーフパネルの上方からの荷重を下方へ効率的に伝達する。【解決手段】レインフォース12は、ルーフ側板部3bの後端近傍で上下方向に延び、その上端部にはエネルギー吸収部材14が固定される。レインフォース12は、閉断面状に形成されてルーフ側板部3bの車幅方向内側面7に固定され、レインフォース12の下端部は、ボディのレール部に下方から支持され、レインフォース12の上端34は、ルーフ上板部3aから下方へ離間した所定の高さ位置に配置される。エネルギー吸収部材14のルーフ支持板部21fは、レインフォース12の上端34よりも上方に配置されて、ルーフ上板部3aを下方から支持する。エネルギー吸収部材14は、上方からの荷重に対してレインフォース12よりも変形し易い断面ハット状に形成されて上下方向に延び、上方からの荷重の入力によって変形してエネルギーを吸収する。【選択図】図6
