PROBLEM TO BE SOLVED: To contribute to stabilization of a deformation form in a configuration in which a resin inner panel and a resin outer panel are joined together.SOLUTION: In a back door body 10, an outer upper panel 24 made of CFRP is joined to an upper part of an inner panel 20 made of CFRP, and an outer lower panel 22 made of polypropylene is joined to a lower part of the inner panel 20. In an outer edge part of the back door body 10, the upper side is a first outer edge part 10A reinforced by the outer upper panel 24, and the lower side is a second outer edge part 10B having strength lower than the first outer edge part 10A. Boundary parts 10C1, 10C2 between the first outer edge part 10A and the second outer edge part 10B having strength difference are provided at a portion that is weakened by adjacency of a small window opening 28. Thus, at the time of collision or the like, the back door body 10 is easily deformed at the boundary parts 10C1, 10C2, thereby contributing to stabilization of a deformation form.SELECTED DRAWING: Figure 3

    【課題】樹脂製のインナパネルと樹脂製のアウタパネルとが互いに接合された構成において、変形形態の安定化に寄与する。【解決手段】バックドア本体10では、CFRP製のインナパネル20の上部にCFRP製のアウタアッパパネル24が接合され、該インナパネル20の下部にポリプロピレン製のアウタロアパネル22が接合されている。このバックドア本体10の外縁部は、上部側がアウタアッパパネル24によって補強された第1外縁部10Aとされ、下部側が第1外縁部10Aよりも低強度な第2外縁部10Bとされている。そして、このように耐力差がある第1外縁部10Aと第2外縁部10Bとの境界部10C1、10C2が、小窓用開口部28の隣接によって弱体化した部位に設定されている。これにより、衝突時などには、バックドア本体10が境界部10C1、10C2において変形し易くなるので、変形形態の安定化に寄与する。【選択図】図3
