A vehicle-width-direction inner side end of each roof side rail has a concave-convex shape in a side view along the vehicle front-rear direction, a vehicle-width-direction outer side end of the roof reinforcement has a concave-convex shape in the side view, and the concave-convex shaped end of each roof side rail and the concave-convex shaped end of the roof reinforcement 30 intersect each other in the side view. ## Claims ### Claim 1 An upper body structure of a vehicle, the upper body structure comprising: a pair of left and right roof side rails coupled to respective ends of a roof panel in a vehicle width direction, the pair of left and right roof side rails extending in a vehicle front-rear direction; and a roof reinforcement that couples intermediate portions in the vehicle front-rear direction of the pair of roof side rails in the vehicle width direction, wherein a vehicle-width-direction inner side end of each roof side rail has a concave-convex shape in a side view along the vehicle front-rear direction, a vehicle-width-direction outer side end of the roof reinforcement has a concave-convex shape in the side view, and the concave-convex shaped end of each roof side rail and the concave-convex shaped end of the roof reinforcement intersect each other in the side view. ### Claim 2 (depends on 1) The upper body structure of a vehicle according to claim 1, wherein the roof reinforcement is joined to each of the roof side rails near an intersecting point where the concave-convex shaped end of each roof side rail and the concave-convex shaped end of the roof reinforcement intersect. ### Claim 3 (depends on 2) The upper body structure of a vehicle according to claim 2, wherein one of each roof side rail and the roof reinforcement includes at least one protrusion extending to the other of each roof side rail and the roof reinforcement, and the at least one protrusion is joined to the other of each roof side rail and the roof reinforcement. ### Claim 4 (depends on 3) The upper body structure of a vehicle according to claim 3, wherein each roof side rail includes a roof rail outer portion and a roof rail inner portion, the roof rail outer portion defining a vehicle-width-direction outer side wall, the roof rail inner portion defining, jointly with the roof rail outer portion, a closed cross-section extending in the vehicle front-rear direction, and the at least one protrusion extends from the vehicle-width-direction outer side end of the roof reinforcement and is joined to an upper surface of the roof rail outer portion. ### Claim 5 (depends on 4) The upper body structure of a vehicle according to claim 4, wherein the at least one protrusion comprises a plurality of protrusions, and convex portions of the roof rail outer portion are joined to the roof panel. ### Claim 6 (depends on 1) The upper body structure of a vehicle according to claim 1, wherein one of each roof side rail and the roof reinforcement includes at least one protrusion extending to the other of each roof side rail and the roof reinforcement, and the at least one protrusion is joined to the other of each roof side rail and the roof reinforcement. ### Claim 7 (depends on 6) The upper body structure of a vehicle according to claim 6, wherein each roof side rail includes a roof rail outer portion and a roof rail inner portion, the roof rail outer defining a vehicle-width-direction outer side wall, the roof rail inner portion defining, jointly with the roof rail outer portion, a closed cross-section extending in the vehicle front-rear direction, and the at least one protrusion extends from the vehicle-width-direction outer side end of the roof reinforcement and is joined to an upper surface of the roof rail outer portion. ### Claim 8 (depends on 7) The upper body structure of a vehicle according to claim 7, wherein the at least one protrusion comprises a plurality of protrusions, and convex portions of the roof rail outer portion are joined to the roof panel. ### Claim 9 (depends on 1) The upper body structure of a vehicle according to claim 1, wherein the convex portions of the concave-convex shaped end of each roof side rail and the concave portions of the concave-convex shaped end of the roof reinforcement overlap each other in the up-down direction in the side view. ### Claim 10 (depends on 1) The upper body structure of a vehicle according to claim 1, further comprising left and right pillars joined to corresponding left and right roof side rails. ### Claim 11 (depends on 10) The upper body structure of a vehicle according to claim 10, wherein left and right ends of the roof rail reinforcement are between the left and right pillars and the left and right roof side rails. ### Claim 12 (depends on 1) The upper body structure of a vehicle according to claim 1, further comprising left and right gussets joined to bottom surfaces of left and rights ends of the roof rail reinforcement. ### Claim 13 (depends on 12) The upper body structure of a vehicle according to claim 12, wherein the left and right gussets are joined to bottom surfaces of concave portions of the roof rail reinforcement and extend along a convex portion between adjacent concave portions to form a closed cross section between the left and right gussets and the convex portion of the roof rail reinforcement. ### Claim 14 (depends on 13) The upper body structure of a vehicle according to claim 13, wherein the left and right gussets include downward protrusions in the closed cross section. ### Claim 15 (depends on 13) The upper body structure of a vehicle according to claim 13, wherein the vehicle-width-direction inner side end of the left and right roof side rails are between the left and right gusset and the roof rail reinforcement. ### Claim 16 (depends on 1) The upper body structure of a vehicle according to claim 1, wherein the concave-convex shape of the roof side rails is out of phase with the concave-convex shape of the roof rail reinforcement. ### Claim 17 An upper body structure of a vehicle, the upper body structure comprising: a pair of left and right roof side rails coupled to respective ends of a roof panel in a vehicle width direction, the pair of left and right roof side rails extending in a vehicle front-rear direction; and a roof reinforcement that couples intermediate portions in the vehicle front-rear direction of the pair of roof side rails in the vehicle width direction, wherein a vehicle-width-direction inner side end of each roof side rail has bulges in a side view along the vehicle front-rear direction, a vehicle-width-direction outer side end of the roof reinforcement has a concave-convex shape in the side view, and the bulges in the roof side rail and
