Abstract
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 is arranged 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.
