To effectively reinforce the upper part of a center pillar portion without decreasing a production efficiency for a swelling portion that stores therein a rail through which a slide side door runs.SOLUTION: A swelling portion 24 is provided at a roof side rail portion 20 of a vehicle side section structure. A reinforcement member 30 is joined to the roof side rail portion 20 located at the forehead side of the swelling portion 24. Respective external side ends of the front portion and the rear portion of the roof cross member 5 are placed so as to have a clearance therebetween in the vertical direction. The reinforcement member 30 is joined to the external side end portion of the front portion in the vehicle widthwise direction. A side body outer panel 10 and a roof panel 1 are joined to the external side end portion of the rear portion in the vehicle widthwise direction in a triple laid-over manner. A space S is defined by the reinforcement member 30, the front portion of the roof cross member 5, and a roof side inner center panel 23 located inwardly relative to the roof side rail portion 20.SELECTED DRAWING: Figure 6
【課題】スライドサイドドアが走行するレールを格納する膨出部について、生産効率を低下させることなく、センターピラー部の上部を効果的に補強する。【解決手段】車両側部構造のルーフサイドレール部20には膨出部24が設けられ、膨出部24の前方側に位置するルーフサイドレール部20には、補強部材30が接合され、ルーフクロスメンバ5の前部及び後部のそれぞれの外側端は、上下方向に互いに間隔を空けて配置され、前部の車幅方向外側端部には、補強部材30が接合され、後部の車幅方向外側端部には、サイドボディアウタパネル10及びルーフパネル1が3枚重ねで接合される。補強部材30と、ルーフクロスメンバ5の前部と、ルーフサイドレール部20の内側に位置するルーフサイドインナセンタパネル23によって空間部Sが画定されている。【選択図】図6
