To provide a vehicle body side part structure capable of enhancing yield strength of a B-pillar with respect to a side collision load.SOLUTION: An end edge 8 in an inner side of a vehicle width direction of a second plate part 73b extending in a direction intersecting with the longitudinal direction of a vehicle body of a B-pillar outer reinforcement upper 7 is formed in a waveform shape which repeats unevenness in the vehicle width direction over the vertical direction. Accordingly, when a side collision load in vehicle side collision is input in the B-pillar outer reinforcement upper 7, recessed curve parts 8A, 8B, which are recessed toward the outside in the vehicle width direction, are deformed in a direction in which the length of the recessed curve parts 8A, 8C is shortened (reduced). Therefore, breakage due to the side collision load is hardly generated in this portion so that rapid reduction in yield strength due to the breakage is suppressed. Thus, the yield strength of the B-pillar with respect to the side collision load can be enhanced.SELECTED DRAWING: Figure 2

    【課題】側突荷重に対するBピラーの耐力向上を図ることができる車体側部構造を提供する。【解決手段】Bピラーアウタリインフォースメントアッパ7における車体前後方向に対して交差する方向に延在する第2板部73bにおける車幅方向内側の端縁8を、上下方向に亘って車幅方向での凹凸を繰り返す波形状とする。これにより、車両側突時の側突荷重がBピラーアウタリインフォースメントアッパ7に入力された場合にあっては、車幅方向外側に向けて凹となる凹状曲線部8A,8Cの変形は、該凹状曲線部8A,8Cの線長を短くする(縮める)方向となる。このため、この部分では、側突荷重による破断は生じ難くなり、破断に起因する耐力の急速な低下は抑制されることになる。このため、側突荷重に対するBピラーの耐力向上を図ることができる。【選択図】図2
