PROBLEM TO BE SOLVED: To inhibit deformation of a back door which starts at a belt line part.SOLUTION: A back door 1 includes: a door body part 10 formed with a window opening 11 and including an outer panel and an inner panel 13; and reinforcement parts which reinforce the door body part 10. The door body part 10 includes: pillar parts 14 which are formed at both sides of the window opening 11 in a vehicle width direction and extend along a vehicle vertical direction; and a belt line part 15 formed at the side below the window opening 11 in a vehicle vertical direction and extending in the vehicle width direction. Each reinforcement part has: a first reinforcement member 21 which is disposed on the inner panel 13 so as to connect the pillar part 14 with the belt line part 15; and a second reinforcement member 22 disposed along the belt line part 15. The second reinforcement member 22 and the inner panel 13 form a first cylindrical closed cross section part in a range in which the first reinforcement member 21 is disposed and form a second cylindrical closed cross section part at the inner side of the first closed cross section part in the vehicle width direction.SELECTED DRAWING: Figure 2
【課題】ベルトライン部が起点となるバックドアの変形を抑制すること。【解決手段】バックドア1は、窓開口11が形成され、アウタパネル及びインナパネル13を含むドア本体部10と、ドア本体部10を補強する補強部と、を備える。ドア本体部10は、窓開口11の車幅方向両側に形成され車両上下方向に沿って延びるピラー部14と、窓開口11の車両上下方向下側に形成され車幅方向に延びるベルトライン部15と、を有する。ピラー部14とベルトライン部15とを接続するようにインナパネル13上に配置された第1補強部材21と、ベルトライン部15に沿って配置された第2補強部材22と、を有する。第2補強部材22及びインナパネル13は、第1補強部材21が介在する範囲において筒状の第1閉断面部を形成すると共に、第1閉断面部よりも車幅方向内側において筒状の第2閉断面部を形成する。【選択図】図2
