To provide a side part vehicle body structure of an automobile capable of suppressing falling down of a center pillar 3 during a side collision without oppressing a limited space in a cabin and by suppressing a weight increase.SOLUTION: A side part vehicle body structure includes: a pair of right and left side sills 4; and a pair of right and left center pillars 3. Each of the side sills 4 is constituted of a side sill outer panel 41 having a substantially hat-like cross section and a side sill inner panel 42 which has a substantially hat-like cross section and has an inner upper side flange section 425 joined to the side sill outer panel 41. An inner upper surface section 424 of the side sill inner panel 42 has a first projection section 426, a second projection section 427, a third projection section 428, and a fourth projection section 429, which project from the inside in a vehicle width direction to the inner upper side flange section 425. The first projection section 426, the second projection section 427, the third projection section 428, and the fourth projection section 429 are formed at positions facing lower sections of the center pillars 3 in the vehicle width direction.SELECTED DRAWING: Figure 1

    【課題】車室内の限られた空間を圧迫することなく、かつ重量増加を抑えて、側突時におけるセンタピラー3の倒れを抑制できる自動車の側部車体構造を提供することを目的とする。【解決手段】左右一対のサイドシル4と、左右一対のセンタピラー3とを備えた自動車の側部車体構造であって、サイドシル4が、断面略ハット状のサイドシルアウタパネル41と、サイドシルアウタパネル41に接合されるインナ上側フランジ部425を有する断面略ハット状のサイドシルインナパネル42とで構成され、サイドシルインナパネル42のインナ上面部424に、車幅方向内側からインナ上側フランジ部425にかけて隆起した第1隆起部426、第2隆起部427、第3隆起部428、及び第4隆起部429を備え、第1隆起部426、第2隆起部427、第3隆起部428、及び第4隆起部429が、センタピラー3の下部と車幅方向で対向する位置に形成されたことを特徴とする。【選択図】図1
