Summary:PROBLEM TO BE SOLVED: To prevent twist deformation of a back door opening part by concentrating loading weight providing an effect on deformation of the back door opening part to a ridgeline part of an inner panel reinforced with a reinforce.SOLUTION: There is provided a back door opening part structure of a vehicle, in which a back door opening part 1 is formed with a vehicle body panel comprising an inner panel 3 having a projecting part 30 projecting inside of a vehicular room, and a convex shape ridgeline 30A formed on the inner panel 3 extends from an upper part to a lower part of the back door opening part 1. A reinforce 7 is provided along the ridgeline 30A on backside of the inner panel 3 on which the projecting part 30 is provided within an area of an upper curve part 1a where the ridgeline 30A shifts from vehicle vertical direction to vehicle width direction. The reinforce 7 comprises a joint part 7a for the inner panel 3 at a site overlapping with the ridgeline 30A.SELECTED DRAWING: Figure 3 【課題】バックドア開口部の変形に影響を及ぼす負荷荷重をリンフォースで補強されたインナパネルの稜線部分に集中させることにより、バックドア開口部の捩じれ変形を防止することにある。【解決手段】車室内側へ突出する凸部30を有するインナパネル3を備えた車体パネルによってバックドア開口部1が形成され、インナパネル3に形成された凸状の稜線30Aが、バックドア開口部1の上部から下部にかけて延びている車両のバックドア開口部構造において、稜線30Aが車両上下方向から車両幅方向に移行する上部湾曲部1aの範囲内で、凸部30が位置するインナパネル3の裏面側には、稜線30Aに沿ってリンフォース7が設けられ、リンフォース7は、稜線30Aを跨いだ箇所に、インナパネル3との接合部7aを有している。【選択図】図3
