To inhibit a vibration of a roof side rail due to an input from a road surface during running of a vehicle.SOLUTION: A first reinforcement material 70 is disposed in a space 72 at the root of a first junction A1 and coupled to a rail inner panel 40, rail outer panel 30, and outer panel rear part. In addition to the first reinforcement material 70, a second reinforcement material 80 and third reinforcement material are disposed on a vehicle front side and vehicle rear side respectively of an overlap part between a rear end of the rail outer panel 30 and a front end of the outer panel rear part. The reinforcement materials are coupled to the rail inner panel 40 and rail outer panel 30 (outer panel rear part) in an area on a vehicle lower side of the first reinforcement material 70. Accordingly, the rigidities of flanges 44 and 34 are upgraded, and a sectional collapse of the roof side rail 12 is inhibited. Therefore, the rigidity of the entire roof side rail 12 is upgraded. As a result, a vibration of the roof side rail 12 due to an input from a road surface during running of a vehicle can be inhibited.SELECTED DRAWING: Figure 2

    【課題】車両の走行時における路面からの入力によるルーフサイドレールの振動を抑制する。【解決手段】第一補強材70を、第一接合部分A1の根元の空間72内に配置し、レールインナパネル40、レールアウタパネル30及びアウタパネルリアに結合する。第一補強材70に加えて、第二補強材80及び第三補強材を、レールアウタパネル30の後端部とアウタパネルリアの前端部との重ね合わせ部に対する車両前方側及び車両後方側に設け、該補強材を第一補強材70に対する車両下方側の領域において、レールインナパネル40に結合し、レールアウタパネル30(アウタパネルリア)に結合する。以上により、フランジ44、34の剛性が向上し、ルーフサイドレール12の断面崩れが抑制されるため、ルーフサイドレール12全体の剛性が向上する。この結果、車両の走行時における路面からの入力によるルーフサイドレール12の振動を抑制できる。【選択図】図2
