To provide a center pillar structure made of a fiber-reinforced resin capable of exerting a desired characteristic even when a reinforce made of the fiber-reinforced resin is applied to the center pillar.SOLUTION: A center pillar of a vehicle body includes: a pillar body section which has a longitudinal direction and is formed into a hollow substantially cylindrical shape; and a reinforce which is made of a fiber-reinforced resin, is arranged in an internal space of the pillar body section, and is joined to at least a part of an internal surface of the pillar body section. In the reinforce, a total ratio of a first layer and a second layer is higher than that of a third layer and a fourth layer in a first region at one side in the longitudinal direction. A total ratio of the third layer and the fourth layer is higher that of the first layer and the second layer in a second region at the other side in the longitudinal direction.SELECTED DRAWING: Figure 6
【課題】センターピラーに繊維強化樹脂製のリンフォースを適用した場合であっても、所望の特性を発揮可能な繊維強化樹脂製のセンターピラー構造を提供する。【解決手段】長手方向を有し中空の略筒状に形成されたピラー本体部と、ピラー本体部の内部空間に配置されてピラー本体部の内面の少なくとも一部に接合される繊維強化樹脂製のリンフォースと、を備え、リンフォースは、長手方向の一方側の第1の領域では、第1の層及び第2の層の合計比率が第3の層及び第4の層の合計比率よりも高く、長手方向の他方側の第2の領域では、第3の層及び第4の層の合計比率が第1の層及び第2の層の合計比率よりも高い。【選択図】図6
