PROBLEM TO BE SOLVED: To provide a vehicular back door structure that can be suppressed from deforming by enhancing rigidity of a door outer panel.SOLUTION: A vehicular back door structure 100 according to the invention comprises a door outer panel 106 constituting an outer surface of a vehicular back door 104 formed with a window frame 112, and a door inner panel 108 constituting an inner surface of the vehicular back door. The vehicular back door structure further comprises a reinforcing member 110 which is arranged between the door outer panel and the door inner panel and joined to the door outer panel. The reinforcing member, positioned between two corner parts 142 and 144 of a lower end 140 of the window frame, has a dimension La in a vehicle width direction across equal to or more than a half of a length Lb in the vehicle width direction of a region 138 below the window frame of the door outer panel, and extends up to a position away from the lower end of the window frame by a dimension Lc in a vertical direction equal to or more than a half of a length Ld in a vertical direction of the region.SELECTED DRAWING: Figure 4

    【課題】ドアアウタパネルの剛性を高め変形を抑制できる車両用バックドア構造を提供することを目的とする。【解決手段】本発明にかかる車両用バックドア構造100は、窓枠112が形成された車両用バックドア104の外面を構成するドアアウタパネル106と、車両用バックドアの内面を構成するドアインナパネル108とを備える車両用バックドア構造において、車両用バックドア構造はさらに、ドアアウタパネルとドアインナパネルとの間に配置されドアアウタパネルに接合される補強部材110を備え、補強部材は、窓枠の下端140の2つの角部142、144の間に位置していて、ドアアウタパネルのうち窓枠の下側の領域138の車幅方向の長さLbの半分以上にわたる車幅方向寸法Laを有し、窓枠の下端から、領域の上下方向の長さLdの半分以上の上下方向寸法Lcだけ離れた位置まで延びていることを特徴とする。【選択図】図4
