PROBLEM TO BE SOLVED: To prevent the lower part of a backdoor body from generating a large hollow at the rear end collision of a vehicle even if the inner and outer panels composing the lower part are scattered.SOLUTION: The toughness of an outer panel (9) composing a door body (3) is made to be higher than that of an inner panel (7), and a first reinforcing sheet-like material (81) is provided in an internal space (S) in the lower part (3b) of the door body (3) in such a state as bonded to the outer panel (9) and stretched in a vehicle width direction. A second reinforcing sheet-like material (91) is interleaved between the bracket (71) of a latch (111) engaging with a striker (113) provided in a vehicle body (101) and the installation place of the bracket (71) in the inner panel (7) to be fixed. The first reinforcing sheet-like material (81) is also bonded to the second reinforcing sheet-like material (91).

    【課題】車両の後面衝突時においてドア本体のロア部を構成するインナーパネル及びアウターパネルが飛散しても、当該ロア部に大きな穴が開くことを防止する。【解決手段】ドア本体(3)を構成するアウターパネル(9)の靱性をインナーパネル(7)の靱性よりも高くし、ドア本体(3)のロア部(3b)における内部空間(S)に、第1補強シート状物(81)をアウターパネル(9)に接着して車幅方向に広げた状態で設けると共に、第2補強シート状物(91)を車体本体(101)に設けられたストライカ(113)と係合するラッチ(111)のブラケット(71)とインナーパネル(7)のうちこのブラケット(71)の取付け箇所との間に挟み込んで固定し、第1補強シート状物(81)を第2補強シート状物(91)にも接着する。【選択図】図5
