PROBLEM TO BE SOLVED: To provide a side-part car body structure of an automobile that secure a load absorption amount of a center pillar and prevents overload input to a weld zone of a pillar end so as to prevent the weld zone of a pillar end of a pillar inner panel from peeling owing to a side collision load.SOLUTION: A pillar inner panel 14 is provided with a weld zone SW12 of a pillar end which has a ridge part X1 extended substantially vertically from at least one of a roof side rail and a side sill 9 and where the pillar inner panel 14 is welded to the pillar outer panel or the side sill 9 or a roof-side rail, and a substantially flat load transmission suppression part 18, which is wider in a vehicle front-rear direction than a vertically center-side region of the center pillar 12 and substantially flat, opposite the ridge part X1.SELECTED DRAWING: Figure 1

    【課題】センタピラーにおける荷重吸収量の確保と、ピラー端部の溶接部への過負荷入力の防止とを図り、側突荷重によりピラーインナパネルのピラー端部の溶接部が剥離することを防止する自動車の側部車体構造の提供を目的とする。【解決手段】ピラーインナパネル14に、ルーフサイドレールおよびサイドシル9の少なくとも一方から稜線部X1が略垂直に延設され、ピラーインナパネル14がピラーアウタパネルまたはサイドシル9またはルーフサイドレールに溶接されるピラー端部の溶接部SW12と、稜線部X1との間に、センタピラー12の上下方向中央側部位よりも車両前後方向に幅広で、かつ、略平坦な荷重伝達抑制部18が設けられたことを特徴とする。【選択図】図1
