To provide a vehicle side part structure that is able to suppress a shearing load acting on a spot-welding portion between an upper portion of a pillar outer and an upper portion of a pillar inner in the event of side collision, even in a case where a high strength material is used for the pillar outer.SOLUTION: A pillar outer 34 includes: a superimposition portion 34T formed continuously on an upper-end side of a body portion 34H and superimposed on a lower wall portion 24L of a rail outer 24; and an upper-end mounting portion 34U formed continuously on an upper end side of the superimposition portion 34T and joined to an outer wall portion 24S of the rail outer 24. In the pillar outer 34, an amount of projection of a projecting portion 34A from a flange 34C at an upper end of the body portion 34H is set to 50% or less of an amount of extension from a boundary between the pillar outer and the flange 34C of the superimposition portion 34T to a boundary between the pillar outer and the upper-end mounting portion 34U.SELECTED DRAWING: Figure 2

    【課題】ピラーアウタに高強度材を用いた場合においても、側面衝突時にピラーアウタの上部とピラーインナの上部とのスポット溶接部に作用するせん断荷重を抑制することができる車体側部構造を得る。【解決手段】ピラーアウタ34は、本体部34Hの上端側に連続して形成されてレールアウタ24の下壁部24Lに重ね合わせられた重合部34Tと、重合部34Tの上端側に連続して形成されてレールアウタ24の外壁部24Sに接合された上端取付部34Uと、を備えている。ピラーアウタ34は、本体部34Hの上端におけるフランジ34Cからの突出部34Aの突出量が重合部34Tにおけるフランジ34Cとの境界から上端取付部34Uとの境界までの延出量の50%以下に設定されている。【選択図】図2
