Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coupling structure of an upper frame member of a vehicle having a tailgate, for example. 2. Description of the Related Art In a vehicle having a tailgate, it is desired to increase rigidity around an opening at a rear portion of a vehicle body where the tailgate is provided. To reinforce the opening,
Forming a closed cross section on the vehicle body with multiple panel members,
Various reinforcement members have been added. For example, in order to increase the rigidity of an upper frame member supporting an upper portion of a tail gate, a roof rail rear having a closed cross section is formed by a roof rail outer member and a roof rail inner member, and both ends of the roof rail rear are respectively formed. It has been proposed to weld to an extension member that constitutes an upper portion of a side wall portion of a vehicle. Further, in order to reinforce the upper portion of the side wall portion, it has been considered to reinforce the vicinity of the extension member with a reinforcement member. [0004] When the end of the roof rail rear having a closed cross section is welded to the extension member, the flange portions along both side edges of the roof rail rear are spot-welded to the extension member and the reinforcement member. Is the general idea. However, simply spot welding the roof flange rear flange portion to an extension member or the like has a limitation in increasing the strength of the joint portion between the two. In this case, even if the rigidity of the roof rail rear itself can be increased by the closed cross section formed by the roof rail outer member and the roof rail inner member, if the coupling strength with the extension member is small, the rigidity of the roof rail rear cannot be fully utilized. . SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a coupling structure of an upper frame member of a vehicle, which can increase the coupling strength between a frame member constituting a roof portion of the vehicle and a side wall portion of the vehicle. According to the present invention, as described in claim 1, a roof rail outer member and a roof rail inner member forming a first closed section, and a second closed section are formed. The present invention is applied to a vehicle having an extension member and a pillar reinforcement member. The edge of the roof rail outer member protrudes from the edge of the roof rail inner member, and the edge of the extension member protrudes from the edge of the pillar reinforcement member. The edge of the roof rail outer member is
While being mounted on the edge of the pillar reinforcement member, the pillar reinforcement member is coupled to the pillar reinforcement member by, for example, spot welding. Also, the edge of the roof rail inner member is
In a state of being placed on the edge of the extension member, the extension member is joined to the extension member by spot welding or the like. In a preferred embodiment of the present invention, spot welding is performed between these edges near the edge of the outer member of the roof rail, that is, at a position facing the weld between the edge of the roof rail inner member and the edge of the extension member. A working hole is formed for use. Further, in a preferred embodiment of the present invention, when spot welding these edges near the edge of the extension member, that is, at a position facing the welded portion between the edge of the roof rail outer member and the edge of the pillar reinforcement member, Working holes to be used are formed.

3, W4, and the flange portions 20, 46, 52 at the welds W9, W10.
And the fact that the flange portions 21, 47, 53 are welded, so that a large bonding strength can be obtained. Further, the flange portions 20 and 46 are joined to each other at a weld portion W7 located between the weld portions W5 and W9, and the flange portion 20 and 46 are located at a weld portion W8 located between the weld portions W6 and W10. Since the members 21 and 47 are joined to each other, the joint strength of the closed cross-section portions 30 and 51 can be further increased. According to the first aspect of the present invention, it is possible to increase the bonding strength between the upper frame member forming the roof of the vehicle and the upper frame member forming the side wall of the vehicle.

Claims: 1. A roof rail outer member extending in a vehicle width direction of a roof portion of a vehicle; and a roof rail outer member which is assembled to the roof rail outer member and cooperates with the roof rail outer member. A roof rail inner member that forms a first closed cross-section that extends toward the vehicle, an extension member that forms a part of an upper edge of an inner panel on a side wall of the vehicle, and extends inside the vehicle, and that is disposed outside the vehicle of the inner panel. And a pillar reinforcement member forming a second closed section extending inwardly of the vehicle in cooperation with the extension member. An open end of the first closed section is an edge of the roof rail outer member. Is provided so as to protrude from an edge of the roof rail inner member, and an end of the extension member has an opening edge at the second closed cross-sectional portion. The roof rail outer member is coupled to the pillar reinforcement member in a state where the edge of the roof rail outer member is placed on the edge of the pillar reinforcement member, and the roof rail inner member is provided. The upper frame member of the vehicle is connected to the extension member while the edge of the upper member is placed on the edge of the extension member.
