PROBLEM TO BE SOLVED: To provide a reinforcement structure of a vehicular skeleton member capable of efficiently improving a reinforcement effect on the vehicular skeleton member by a rib thereof while reducing the weight of the rib.SOLUTION: A reinforcement structure 10 of a vehicular skeleton member 12 comprises: a rib 30 for reinforcing a plane part 25 of the vehicular skeleton member 12 by integrally connecting standing wall parts 26 formed on the plane part 25; a thickness gradual change part 40 in which the thickness of the rib 30 is increased toward the standing wall part 26 and a height gradual change part 50 in which the height of the rib 30 is increased toward the standing wall part, which are formed at a connection portion between the rib 30 and the standing wall part 26; a first curved part 42 formed in the thickness gradual change part 40; a second curved part 44 formed in the thickness gradual change part 40 on the side of the standing wall part 26 from the first curved part 42, and having a curvature larger than that of the first curved part 42; a third curved part 52 formed in the height gradual change part 50; and a forth curved part 54 formed in the height gradual change part 50 on the side closer to the standing wall part 26 than the third curved part 52, and having a curvature larger than that of the third curved part 52.SELECTED DRAWING: Figure 3

    【課題】リブの重量を低減させつつ、そのリブによって車両用骨格部材に対する補強効果を効率よく向上させられる車両用骨格部材の補強構造を得る。【解決手段】車両用骨格部材12の平面部25に形成された立壁部26同士を一体に連結して平面部25を補強するリブ30と、リブ30の立壁部26との連結部分に形成され、立壁部26に向かうに従って、リブ30の厚さが厚くされる厚さ徐変部40及びリブ30の高さが高くされる高さ徐変部50と、厚さ徐変部40に形成された第1湾曲部42と、第1湾曲部42よりも立壁部26側における厚さ徐変部40に形成され、第1湾曲部42よりも曲率の大きい第2湾曲部44と、高さ徐変部50に形成された第3湾曲部52と、第3湾曲部52よりも立壁部26側における高さ徐変部50に形成され、第3湾曲部52よりも曲率の大きい第4湾曲部54と、を備えた車両用骨格部材12の補強構造10とする。【選択図】図3
