To provide a vehicle back door opening reinforcement structure designed in consideration of rigidity improvement of a trough to which a stay is connected and water immersion.SOLUTION: A trough 106 includes: an outer wall part 106a bent toward a vehicle front side from a rear end 138 of an outer panel 134 of a rear pillar 104; a front wall part 106b bent from a front end of the outer wall part 106a toward an inner side in a vehicle width direction; and an inner wall part 106c bent from an end portion on the inner side in the vehicle width direction of the front wall part 106b toward a vehicle rear side to be connected to a rear end 140 of an inner panel 136 of the rear pillar 104. A reinforcement structure 100 includes: a stay connecting part 112 disposed on the outer wall part 106a of the trough 106 and to which a stay 110 is connected; and a reinforcement member 116 connected at an inner side of the rear pillar 104 to a region of the trough 106 including the stay connecting part 112. The reinforcement member 116 is connected along the outer wall part 106a, the front wall part 106b, and the inner wall part 106c of the trough 106.SELECTED DRAWING: Figure 6
【課題】ステーが接続されるトルーフの剛性向上および浸水に配慮した車両バックドア開口部補強構造を提供する。【解決手段】トルーフ106は、リアピラー104のアウタパネル134の後端138から車両前方に屈曲する外側壁部106aと、外側壁部106aの前端から車幅方向内側に屈曲する前側壁部106bと、前側壁部106bの車幅方向内側の端部から車両後方に屈曲してリアピラー104のインナパネル136の後端140に接合される内側壁部106cを有する。補強構造100は、トルーフ106の外側壁部106aに設けられてステー110が接続されるステー接続部112と、リアピラー104の内側にてトルーフ106のステー接続部112を含む範囲に接合される補強部材116を備える。補強部材116は、トルーフ106の外側壁部106a、前側壁部106b、および内側壁部106cに沿って接合される。【選択図】図6
