UPPER BODY STRUCTURE OF VEHICLE
FIG6 is a cross-sectional view showing main components of the upper body structure of the vehicle when taken along line B-B of FIG2
As shown in FIG6, the rail skeletal member 22 has an approximately rectangular closed cross-section, with one side of the rectangle inside the vehicle being formed by the rail inner member 20 and the other three sides being formed by the rail outer member 18. The one side of the closed cross-section inside the vehicle is referred to as an inner wall 42. The inner wall 42 is formed by the rail inner member 20. Among the walls forming the other three sides, two walls directed approximately outside of the vehicle are referred to as an upper outer wall 44 and a lower outer wall 46, and the last wall directed upward is referred to as a ceiling wall 48. The upper outer wall 44 and the lower outer wall 46 are curved and bent to protrude to the outside of the vehicle, and form a ridgeline 50 extending longitudinally along a boundary of the upper outer wall 44 and the lower outer wall 46.

['1. An upper body structure of a vehicle, comprising: left and right roof side rails (12) each including a rail outer member (18) located laterally outside the vehicle and a rail inner member (20) located laterally inside the vehicle and forming a closed cross-section structure with the rail outer member (18), the left and right roof side rails (12) extending in a longitudinal direction along left and right sides of a roof of the vehicle; a roof cross member (14) extending across the left and right roof side rails (12), with both ends of the roof cross member (14) connected individually to the left and right roof side rails (12); and a reinforcing member (24) disposed in the closed cross-section structure of the left and right roof side rails (12) at a position where each roof side rail (12) is connected to the roof cross member (12), wherein the rail outer member (18) includes an upper outer wall (44) and a lower outer wall (46) which are curved and bent to protrude laterally to the outside of the vehicle to form a ridgeline (50) extending longitudinally along a boundary between the upper outer wall (44) and the lower outer wall said upper body structure of a vehicle being  characterized in that the reinforcing member (24) includes a base (56) bonded to the upper outer wall (44) and the lower outer wall (46), a facing plate (58) facing the rail inner member (20), and a supporting wall (60) standing on the base (56) to support the facing plate (58), and the facing plate (58) is at least partially located on the laterally inside of a plane (P) passing through two edge lines (62, 64) of the upper outer wall (44) and the lower outer wall (46), each edge line opposing the ridgeline (50).', '3. The upper body structure of the vehicle according to claim 2, wherein the facing plate (58) is connected to the base (56) either on an upper edge line (66) or a lower edge line (68) of the facing plate (58).']
