To disperse and properly transmit, even in the event of front collision, a front collision load, caused by the front collision, to each part of a vehicle body.SOLUTION: A vehicle body side part structure is based on a vehicle body side part structure in which a vehicle body side part includes window frames 21, on a vehicle body side part, provided with a sub-pillar 23 in a front part of a front pillar upper 13A and provided with a main pillar 25 in a rear part thereof. The main pillar 25 has a closed cross-sectional structure by joining an inner panel 51 and an outer panel 53 to each other in a center-to-center manner. A first stiffener 31 for reinforcing an upper half part of at least the main pillar 25 and a second stiffener 33 for reinforcing a lower half part of the main pillar 25 are provided between the inner panel 51 and the outer panel 53. The first stiffener 31 and the second stiffer 33 are joined in a layered state at an intermediate part along a vehicle height direction of the main pillar 25 and have portions 31h and 33d having cross-sectional shapes different from each other.SELECTED DRAWING: Figure 1B
【課題】前面衝突が生じた場合であっても、前面衝突に伴う前突荷重を車体各部へと分散して適確に伝達する。【解決手段】車体側部構造は、フロントピラーアッパ13Aの前部にサブピラー23を、その後部にメインピラー25をそれぞれ設けた窓枠21を車体側部に備える車体側部構造が前提となる。メインピラー25は、インナパネル51及びアウタパネル53を最中合わせに接合することで閉断面構造を有する。インナパネル51及びアウタパネル53の間に、少なくともメインピラー25に係る上半部を補強する第1スティフナ31と、メインピラー25に係る下半部を補強する第2スティフナ33と、をそれぞれ設ける。第1スティフナ31及び第2スティフナ33は、メインピラー25の車高方向に沿う中間部において積層状態で接合される一方、それぞれが相互に異なる断面形状の部分31h、33dを有する。【選択図】図1B
