To suppress the increase in vehicle body weight and to improve the shock-absorbing performance with respect to a vehicular roof structure.SOLUTION: A vehicular roof structure that reinforces a roof panel includes: first members 1; second members 2; third members 3; and a shock-absorbing member 6. The first members 1 are placed along roof cross members 14 and 15, respectively, and have respective end portions 21 at the internal side in the vehicle widthwise direction joined to the roof cross members 14 and 15, respectively. The second members 2 have respective one ends 23 joined to roof side rails 12 and 13, respectively, and have another ends 24 joined to the end portions 22 of the respective first members 1 at the external side in the vehicle widthwise direction. The third members 3 have the moving directions of respective one ends 25 constrained in the vehicle widthwise direction near the center portion of a roof panel 11, and have another ends 26 joined to the respective nearby locations to the joined portions between the first member 1 and the second member 2. The shock-absorbing member 6 functions so as to prevent the movements of the one ends 25 of the respective third members 3. The respective first members 1, respective second members 2, and respective third members 3 are placed symmetrically around a symmetrical line that extends in the back-and-forth direction in an upper planar view.SELECTED DRAWING: Figure 2

    【課題】車両用ルーフ構造に関し、車体重量の増加を抑制し、緩衝性能を向上させる。【解決手段】ルーフパネルを補強する車両用ルーフ構造において、第一部材1,第二部材2,第三部材3,緩衝部材6を備える。第一部材1は、ルーフクロスメンバー14,15に沿って配置され、車幅方向内側の端部21がルーフクロスメンバー14,15に接合される。第二部材2は、一端23がルーフサイドレール12,13に接合され、他端24が第一部材1における車幅方向外側の端部22に接合される。第三部材3は、ルーフパネル11の中央部近傍で一端25の移動方向が車幅方向に拘束され、他端26が第一部材1と第二部材2との接合部近傍に接合される。緩衝部材6は、第三部材3の一端25の移動を妨げるように機能する。第一部材1,第二部材2,第三部材3の各々は、上面視で前後方向に延在する対称線を中心として対称に配置される。【選択図】図2
