To provide a back door inner panel for a vehicle, which is able to hinder deformation of an outer peripheral flange, resulting from contraction of an inner panel, without decreasing manufacturing efficiency and increasing man hours for assembly.SOLUTION: An inner panel A10 made of synthetic resin comprises a glass opening 10, a glass opening upper-side part 20, a lower part 30, and a pair of glass opening side edge parts 40 coupling the glass opening upper-side part 20 and the lower part 30. In the inner panel, an outer peripheral flange 51 is formed on an outer edge of the lower part 30. The lower part 30 has: a box-shaped protruding part 35; a first groove 341 surrounding the box-shaped protruding part 35; and a second groove 342 located on the outer periphery side of the first groove 341. Peripheral edge portion reinforcement radiation ribs 383 radially arranged from the box-shaped protruding part 35 toward the outer peripheral flange 51 are provided on the left and right sides of the lower end of the lower part 30. The end edges of the peripheral edge portion reinforcement radiation ribs 383 are connected to the box-shaped protruding part 35, the first groove 341 and the second groove 342.SELECTED DRAWING: Figure 8

    【課題】 製造効率の低下および組立工数の増加を招くことなく、インナパネルの収縮に伴う外周フランジの変形を抑制することが可能な車両用バックドアインナパネルを提供する。【解決手段】 ガラス開口10と、ガラス開口上辺部20と、下部30と、ガラス開口上辺部20と下部30とを連結する一対のガラス開口側縁部40と、を備える合成樹脂製のインナパネルA10であって、下部30の外縁には、外周フランジ51が形成され、下部30には、箱形膨出部35と、箱形膨出部35を取り囲む第1凹溝341と、第1凹溝341の外周側に位置する第2凹溝342と、が形成され、下部30の下端の左右両側には、箱形膨出部35から外周フランジ51に向けて放射状に配置された周縁部分補強放射リブ383がそれぞれ設けられ、周縁部分補強放射リブ383の端縁が、箱形膨出部35と、第1凹溝341と、第2凹溝342と、につながっている。【選択図】 図8
