To provide a hinge reinforcement having first, second, and third connection parts and a first reinforcement part around a door hinge to improve rigidity of a back door and inhibit swinging of the back door around the door hinge set to its axis of swinging.SOLUTION: In a hinge reinforcement structure of a back door 1, a door hinge 5 connected to a hinge reinforcement 4 is provided at a vehicle upper part of an inner panel 2 and a first connection part 11 located at the vehicle upper side relative to the door hinge 5 and a second connection part 12 located at the vehicle lower side relative to the door hinge 5 are provided as connection parts between the hinge reinforcement 4 and the inner panel 2. A third connection part 13 which is a connection part between the hinge reinforcement 4 and the inner panel 2 is disposed at an outer step part 21 of the inner panel 2. The third connection part 13 is located in a range, where the first connection part 11 and the second connection part 12 are disposed, as seen in a vehicle vertical direction in a vehicle rear view and is provided with a first reinforcement part 41 extending from the second connection part 12 and the third connection part 13. The third connection part 13 or the second connection part 12 is located on an extension line of the first reinforcement part 41.SELECTED DRAWING: Figure 2

    【課題】ドアヒンジの周辺に第1、第2及び第3連結部と第1補強部を有するヒンジリンフォースメントを設け、バックドアの剛性を向上させ、ドアヒンジを軸としたバックドアの揺動を抑制する。【解決手段】インナパネル2の車両上部には、ヒンジリンフォースメント4と連結されるドアヒンジ5が設けられ、ヒンジリンフォースメント4とインナパネル2との連結部として、ドアヒンジ5よりも車両上側の第1連結部11と、ドアヒンジ5よりも車両下側の第2連結部12を有するバックドア1のヒンジリンフォースメント構造において、インナパネル2の外側段差部21には、ヒンジリンフォースメント4とインナパネル2との連結部の第3連結部13が配置され、第3連結部13は、車両後方視で、第1連結部11と第2連結部12との車両上下方向の範囲内に位置し、第2連結部12及び第3連結部13から延出する第1補強部41が設けられ、第1補強部41の延長線上に第3連結部13または第2連結部12が位置している。【選択図】図2
