A reinforcing plate (reinforcing member) 130 for reinforcing the tailgate hinge 126 is disposed forward of the gutter outer member front portion 128.
As shown in fig. 8 and 9, a joining portion 132 that is joined to the rear pillar inner 120 (rear pillar inner upper 1206) is provided at the vehicle rear end portion of the reinforcement plate 130. The joint portion 132 is provided on the vehicle width direction inner side of the gutter outer member 100 (see fig. 7).
The reinforcing plate 130 is formed in a substantially rectangular shape in plan view, and is integrally formed with a flat plate-like planar portion 134 and a joining portion 132 bent downward from a vehicle rear end portion of the planar portion 134.
The vehicle body rear upper portion 10 of the vehicle to which the vehicle body upper structure of the present embodiment is applied is basically configured as described above, and the operational effects thereof will be described next.
In the present embodiment, the gutter outer 100 has a joining flange 101 that bulges inward in the vehicle width direction from the side outer panel 24 and folds back outward in the vehicle width direction. The sink outer member 100 and the outer sink 34 are joined via a joining flange 101. Further, a recessed portion 114 recessed toward the vehicle width direction outer side (the side outer panel 24 side) is provided in a fitting portion 113 between the gutter outer member 100 and the outer gutter 34.
In the present embodiment, the joining flange 101 that bulges inward in the vehicle width direction from the side outer panel 24 of the gutter outer member 100 and is folded back outward in the vehicle width direction is joined to the joining flange 35 of the outer gutter 34. Thus, a plurality of joints including the 1 st joint P1 to the 4 th joint P4 are provided. These plural joints are covered with the side outer panel 24 from the outside in the vehicle width direction (see fig. 4B), and therefore can be prevented from being exposed to the outside. Thus, in the present embodiment, when the tailgate 124 is opened, the spot welding pits of the drop floor outer 100 and the outer drop floor 34 are prevented from being exposed to the outside.
In the present embodiment, the recess 114 of the fitting portion 113 provided between the sink outer 100 and the outer sink 34 can be easily filled with, for example, a rust-proofing sealant, thereby achieving a rust-proofing effect.
In the present embodiment, the gutter outer 100 is fixed to the joining flange 116 formed by folding back the end of the outer surface of the side outer panel 24. Thus, in the present embodiment, the fixing portion of the gutter outer 100 to the side outer panel 24 is provided at a portion that is not visible from the outer surface of the side outer panel 24. As a result, in the present embodiment, it is possible to appropriately prevent the fixed portion between the gutter outer 100 and the side outer panel 24 from being exposed to the outside.
In the present embodiment, the gutter outer 100 has a gutter outer front 128 that faces the end of the outer surface of the side outer panel 24 and reduces the cross-sectional area of the front portion in the vehicle body longitudinal direction toward the front. A reinforcing plate (reinforcing member) 130 for reinforcing the tailgate hinge 126 is disposed forward of the gutter outer member front portion 128.
In the present embodiment, the gutter outer 100 has the gutter outer front 128 that reduces the cross-sectional area forward, so that a space can be secured corresponding to the reduced cross-sectional area, and a reinforcing plate (reinforcing member) 130 that reinforces the tailgate hinge 126 can be disposed in the space. As a result, in the present embodiment, when the tailgate 124 is opened and closed, the rigidity and strength against the load input to the tailgate hinge 126 can be improved.
In the present embodiment, a joining portion 132 that is joined to the rear pillar inner 120 (the rear pillar inner upper 1206) is provided at the vehicle rear end portion of the reinforcement plate 130. In the present embodiment, by providing the joint portion 132, when the tailgate 124 is opened and closed, the rigidity and strength with respect to the load input to the tailgate hinge 126 can be improved, and the load input to the tailgate hinge 126 can be made to flow (be released) from the vehicle rear end portion of the reinforcement plate 130 to the rear pillar inner 120 (the rear pillar inner upper 120 b).
In the present embodiment, the joint portion 132 is provided on the vehicle width direction inner side of the gutter outer member 100. In the present embodiment, the joint portion 132 is disposed on the vehicle width direction inner side of the gutter outer member 100, so that the gutter outer member 100 can be prevented from becoming an obstacle when the reinforcing plate 130 as the reinforcing member is attached to the vehicle body. As a result, in the present embodiment, the reinforcing plate 130 can be easily joined to the rear pillar inner 120 (the rear pillar inner upper 1206).
