To provide a vehicular skeleton component of which improvement of a rigidity and weight saving are achieved.SOLUTION: An A-pillar lower 1, which is a vehicular skeleton component, has: an outer panel 3 having a hat-shaped cross section which has a substantially T shape in a plan view, and of which a cross section crossing respective parts equivalent to a lateral side and a vertical side of the substantially T shape comprises a top plate part 3a, a vertical wall part 3b and a flange part 3c; and an inner panel 5 which is joined to the flange part 3c of the outer panel 3, and forms a closed cross section between itself and the outer panel 3, and the inner panel 5 and the outer panel 3 are made of metal. Plural stiffening members 7 made of resin, of which one end joined to an inner surface 3d of the outer panel 3 and the other end is joined to an inner surface 5a of the inner panel 5, is provided in a space formed between the outer panel 3 and the inner panel 5. A shape and arrangement of the stiffening member 7 are set based on an analysis result by a shape optimization analysis method, and a shape of the stiffening member 7 is a columnar shape or a columnar shape of which both ends are bulged.SELECTED DRAWING: Figure 1

    【課題】剛性の向上と軽量化を達成した自動車用骨格部品を提供する。【解決手段】本発明に係る自動車用骨格部品であるAピラーロア1は、平面視において略T字形状で、該略T字形状の横辺および縦辺に相当するそれぞれの部位に交差する断面が天板部3aと縦壁部3bとフランジ部3cとからなる断面ハット形状のアウタパネル3と、アウタパネル3のフランジ部3cに接合されてアウタパネル3との間に閉断面を形成するインナパネル5とを有し、インナパネル5とアウタパネル3は金属からなるものにおいて、アウタパネル3とインナパネル5の間に形成される空間内に、一端がアウタパネル3の内面3dに、他端がインナパネル5の内面5aにそれぞれ接合された樹脂製の複数の補剛部材7を有し、補剛部材7の形状及び配置は、形状最適化解析方法による解析結果に基づいて設定され、補剛部材7の形状は、柱状または両端部が膨隆する柱状を有するものである。【選択図】 図1
