To provide a back door structure which realizes a handle part capable of securing rigidity with a simple structure to achieve improvement of assemblability and cost reduction.SOLUTION: In a back door 1, a panel member 3 is joined to an outer surface of a frame member 2. The back door 1 is opened or closed by using a handle part H provided at the panel member 3. The panel member 3 has: an outer vertical wall part 3b located at the vehicle outer side and extending in a vehicle vertical direction; an inner vertical wall part 3c located at the vehicle inner side and extending in the vehicle vertical direction; and a connection part 3d which connects a lower end part of the outer vertical wall part 3b with an upper end part of the inner vertical wall part 3c. The connection part 3d includes a plane part 3e extending in a vehicle width direction. The plane part 3e has an opening 3f at a position corresponding to the handle part H. A handle bracket 4, having a grip part 4a recessed to the vehicle upper side at a position corresponding to the opening 3f, is fixed to the upper side of the plane part 3e.SELECTED DRAWING: Figure 3

    【課題】簡略な構造で剛性を確保可能なハンドル部を実現することで組付け性の向上と低コスト化が可能なバックドア構造を提供する。【解決手段】バックドア1は、フレーム部材2の外側面にパネル部材3が接合されており、パネル部材3に設けられるハンドル部Hを用いて開閉される。パネル部材3は、車両外側に位置し車両上下方向に延びている外側縦壁部3bと、車両内側に位置し車両上下方向に延びている内側縦壁部3cと、外側縦壁部3bの下端部と内側縦壁部3cの上端部との間を接続している接続部3dと、を有し、接続部3dは、車両幅方向に延びている平面部3eを含み、平面部3eは、ハンドル部Hに対応する位置に開口部3fを有する。平面部3eの上側には、開口部3fに対応する位置に車両上方に凹んだ把持部4aを有するハンドルブラケット4が固定されている。【選択図】図3
