PROBLEM TO BE SOLVED: To provide a vehicular back door inner panel designed such that rigidity can be improved while a weight reduction is achieved.SOLUTION: An inner panel A10, made of synthetic resin, comprises an opening 10, an upper part 20, a skirt part 30, and a pair of side parts 40. The skirt part 30 has: an opening lower-side part 31; a pair of coupling parts 32 located on both left and right sides of the opening lower-side part 31 and by which the lower end of the side parts 40 are coupled; and a frame part 33 coupled to the pair of coupling parts 32. In the opening lower side part 31, coupling part 32 and frame part 33, a first recessed groove 341 is formed, the first recessed groove being open in a rearward direction of the vehicle. In an area surrounded by the first recessed groove 341 in the skirt part 30, a box-shaped protrusion part 35 is formed, the box-shaped protrusion part protruding in the rearward direction of the vehicle with respect to a bottom face 34a of the first recessed groove 341. In the coupling part 32 and frame part 33, a second groove 342 is formed, the groove being located further on the outer-periphery side than the first recessed groove 341 and a bottom face 342a being located further in a rearward direction of the vehicle than a bottom face 341a of the first recessed groove 341.SELECTED DRAWING: Figure 2
【課題】 軽量化を図りつつ、剛性を向上させ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】 開口部10、上部20、裾部30および一対の側部40を備える合成樹脂製のインナパネルA10であって、裾部30は、開口下辺部31と、開口下辺部31の左右両側に位置し、かつ側部40の下端がつながる一対の連結部32と、一対の連結部32につながる枠部33と、を有し、開口下辺部31、連結部32および枠部33には、車両後方に向けて開口した第1凹溝341が形成され、裾部30において第1凹溝341により囲まれた領域には、第1凹溝341の底面34aに対して車両後方に向けて膨出する箱形膨出部35が形成され、連結部32および枠部33には、第1凹溝341よりも外周側に位置し、かつ底面342aが第1凹溝341の底面341aよりも車両後方に位置する第2凹溝342が形成されている。【選択図】 図2
