To obtain a reinforcing structure of a skeleton member in a vehicle capable of ensuring the strength and rigidity of the minimum portion at which the size of a cross-sectional shape is the smallest, in a resin-made skeleton member whose size of the cross-sectional shape is not constant.SOLUTION: A reinforcing structure 10 of a skeleton member 20 in a vehicle is provided with: a resin-made skeleton member 20 which is formed into a closed cross-sectional shape whose size of the cross-sectional shape orthogonal to the longitudinal direction is not constant, and which configures a skeleton of the vehicle; and a reinforcing member 12 made of a fiber reinforced resin, integrally molded into a sheet-like shape on a surface of the skeleton member 20. The reinforcing member 12 has: a first reinforcing part 14 which includes one surface along the longitudinal direction of the skeleton member 20, and a cross-section of which is substantially arranged into a U-shape; and a second reinforcing part 16 which includes the other surface along the longitudinal direction of the skeleton member 20, and a cross-section of which is substantially arranged into a U-shape. At a minimum portion 32 at which the size of the cross-sectional shape of the skeleton member 20 is the smallest, a part 14A of the first reinforcing part 14 and a part 16A of the second reinforcing part 16 overlap each other.SELECTED DRAWING: Figure 2
【課題】断面形状の大きさが一定とされていない樹脂製の骨格部材において、その断面形状の大きさが最も小さい最小部の強度及び剛性を確保できる車両における骨格部材の補強構造を得る。【解決手段】長手方向と直交する断面形状の大きさが一定でない閉断面形状に形成され、車両の骨格を構成する樹脂製の骨格部材20と、骨格部材20の表面にシート状に一体成形された繊維強化樹脂製の補強部材12と、を備えた車両における骨格部材20の補強構造10であって、補強部材12は、骨格部材20の長手方向に沿った一方の表面を含んで断面略「U」字状に配置された第1補強部14と、骨格部材20の長手方向に沿った他方の表面を含んで断面略「U」字状に配置された第2補強部16と、を有し、骨格部材20の断面形状の大きさが最も小さい最小部32において、第1補強部14の一部14Aと第2補強部16の一部16Aとが互いにオーバーラップして重ねられている。【選択図】図2
