To form a roof member by a high strength steel plate and maintain bond strength.SOLUTION: A center member 10 formed by an ultra high strength steel plate has: a front side upper surface part 11A disposed above a bottom surface part 15 and at the front side of the bottom surface part 15; a front side middle surface part 13A disposed between the front side upper surface part 11A and the bottom surface part 15; a first front side ridge part 21A connecting the front side upper surface part 11A with the front side middle surface part 13A; a second front side ridge part 22A connecting the front side middle surface part 13A with the bottom surface part 15; and a third front side ridge part 23A which is offset relative to the first front side ridge part 21A in a width direction and connects the front side upper surface part 11A with the bottom surface part 15. The first front side ridge part 21A and the second front side ridge part 22A continue into the third front side ridge part 23A.SELECTED DRAWING: Figure 2
【課題】ルーフメンバを、高張力鋼板で成形し、且つ接着強度を保持する。【解決手段】超高張力鋼板により形成センターメンバ10は、底面部15の上方で底面部15の前方側に配置された前側上面部11Aと、前側上面部11Aと底面部15の間に配置された前側中面部13Aと、前側上面部11Aと前側中面部13Aとの間を繋いでいる第1の前側稜線部21Aと、前側中面部13Aと底面部15との間を繋いでいる第2の前側稜線部22Aと、第1の前側稜線部21Aに対して幅方向にずれて、前側上面部11Aと底面部15との間を繋いでいる第3の前側稜線部23Aとを有する。第1の前側稜線部21Aと第2の前側稜線部22Aは、第3の前側稜線部23Aに連続している。【選択図】図2
