To provide an automobile skeleton structure which can highly keep a strength of a body skeleton while reducing a used amount of a metallic R/F.SOLUTION: A body skeleton structure is a body skeleton structure constituting a side part of an automobile, includes an outer panel 12, an inner panel 14 which is disposed so as to face the outer panel 12 in order to form a close space long in a first direction between the inner panel and the outer panel 12, a metallic outer R/F 16 disposed in the close space, a resin R/F 22 which is disposed in the close space and is made of a resin, and a foaming material 20 disposed in the close space, where a three-layer structure 26 formed by filling a space between the outer R/F 16 and the resin R/F 22 with the foaming material 20 is disposed in at least a partial range in the first direction out of the closed space.SELECTED DRAWING: Figure 3
【課題】金属製R/Fの使用量を減らしつつも、ボディ骨格の強度を高く保てる自動車の骨格構造を提供する。【解決手段】ボディ骨格構造は、自動車の側部を構成するボディ骨格構造であって、アウタパネル12と、前記アウタパネル12との間に第一方向に長尺な閉空間を形成するべく、前記アウタパネル12と対向して配されたインナパネル14と、前記閉空間内に配された金属製のアウタR/F16と、前記閉空間内に配された樹脂製の樹脂R/F22と、前記閉空間内に配された発泡材20と、を備え、前記閉空間のうち前記第一方向の少なくとも一部範囲には、前記アウタR/F16と前記樹脂R/F22との間に前記発泡材20を充填してなる三層構造体26が配されている。【選択図】図3
