To secure rigidity of a back door with a frame member to achieve reduction of the weight of a panel member and provide a structure having high rigidity at the frame member without considering design with an outer panel member to reduce a plate thickness of the frame member and thereby obtain the back door that is lightweight and has high rigidity.SOLUTION: In a vehicular back door structure in which a back door 1 is provided at a vehicle body rear part, the back door 1 has a metallic frame member 2 comprising a frame inner 3 and a frame outer 4. A resin panel member 5 forming a design surface of the back door 1 is installed at the outer side of the frame member 2.SELECTED DRAWING: Figure 5

    【課題】フレーム部材でバックドアの剛性を担保することでパネル部材を軽量化し、外側のパネル部材によって意匠性を考慮せずにフレーム部材に高い剛性を有する構造を設けることでフレーム部材の板厚を下げ、軽量でかつ高剛性のバックドアを得ることにある。【解決手段】車体後部にバックドア1が設けられている車両のバックドア構造において、バックドア1は、フレームインナ3とフレームアウタ4とから構成される金属製のフレーム部材2を有し、フレーム部材2の外側には、バックドア1の意匠面を形成する樹脂製のパネル部材5が設置されている。【選択図】図5
