Zusammenfassung:	To improve rigidity in a lower part of a back door effectively.SOLUTION: A lower part of an inner reinforcement 40 in a vehicular back door structure is provided with a rear joint part 48 which is joined to a lower part of a door inner panel 20. An outer part of the inner reinforcement 40 is provided with an extension part 41a protruding forward. An intermediate part as seen in a vertical direction of the extension part 41a is provided with a support part 43a which protrudes forward and supports the door inner panel 20. The inner reinforcement 40 located above the support part 43a is provided with an upper joint part which is joined to a door outer panel. An edge of the upper joint part is provided with a reinforcement part 47.SELECTED DRAWING: Figure 3 【課題】バックドアの下部における剛性を効果的に向上させる。【解決手段】車両用バックドア構造におけるインナリンフォースメント４０の下部には、ドアインナパネル２０の下部に接合される後側接合部４８が設けられ、インナリンフォースメント４０の外側部には、前方に突出する延出部４１ａが設けられ、延出部４１ａの上下方向の中間部には、前方に突出し、ドアインナパネル２０を支持する支持部４３ａが設けられ、支持部４３ａよりも上方に位置するインナリンフォースメント４０には、ドアアウタパネルに接合される上側接合部が設けられ、上側接合部の縁部には、補強部４７が設けられている。【選択図】図３
