To suppress deformation of a door main body caused by force acting on a lower part of a back door.SOLUTION: A vehicular back door comprises a door main body (5) formed of an inner panel (10) made of resin and an outer panel (60) made of resin which are jointed to each other, and the vehicular back door is structured into a hatchback type in which an opening at a rear part of a vehicle main body is opened and closed by rotary motion in a vertical direction. An outer peripheral framework structure part (40) with a staircase-shape cross section is formed at an outer periphery portion of the inner panel. An arc-shaped lower framework structure part (50) curved to protrude upward is formed at a portion lower than a window part (7) of the inner panel. A central portion of the lower framework structure part is positioned with an interval above a lower side portion of the outer peripheral framework structure part, and both end portions of the lower framework structure part lead to sites at both ends in the lower side portion of the outer peripheral framework structure part.SELECTED DRAWING: Figure 3

    【課題】バックドアの下部に作用する力でドア本体が変形するのを抑制する。【解決手段】車両用バックドアは、各々樹脂製のインナパネル(10)とアウタパネル(60)とを接合してなるドア本体(5)を備え、上下方向への回転動作により車体本体の後部開口を開閉するハッチバック式に構成される。インナパネルの外周部分には、断面段形状の外周骨格構造部(40)が形成される。インナパネルの窓部(7)よりも下側の部分には、上方へ張り出すように湾曲したアーチ状の下部骨格構造部(50)が設けられる。下部骨格構造部の中央部分は、外周骨格構造部の下辺部分から上方に間隔をあけて位置し、下部骨格構造部の両端部分は、外周骨格構造部の下辺部分における両端部位に繋がる。【選択図】図3
