REAR OPENING STRUCTURE OF VEHICLE AND METHOD FOR MANUFACTURING REAR OPENING STRUCTURE

In a rear opening structure of a vehicle, a roof panel and a trough are arranged on an upper end of an opening for coupling a back door. Each of left and right ends of a vertical wall of the roof panel in the width direction includes a welding point where the roof panel and the trough are welded to each other. Beads that extend in the vertical direction are provided such that each of the beads isarranged in a vicinity of one of the welding points of the left and right ends of the vertical wall and on an inner side of the one of the welding points of the left and right ends. An end of each bead in the vertical direction is connected to at least one of a rear end surface and a horizontal wall of the roof panel. 提供车辆的后部开口构造、车辆的顶棚面板及车辆的后部开口构造的制造方法。顶棚面板和槽部配置在车辆的后部开口构造中后门安装用的开口部的上端。用于将顶棚面板与槽部焊接的焊接焊点分别设置于顶棚面板的纵壁的在车宽方向上的左右两端部。在设置于纵壁的左右两端部的各焊接焊点的附近，并在比左右两端部的焊接焊点靠车宽方向内侧处，分别形成有突条。突条沿车辆上下方向延伸。突条的车辆上下方向的端部与顶棚面板的后端面和横壁中至少一者连接。
