PROBLEM TO BE SOLVED: To provide a coupling structure of a reinforcement front pillar and a reinforcement side sill, which improves the coupling rigidity and strength and suppresses vibration by efficiently dispersedly transmitting a load.SOLUTION: In a coupling structure 1 of a reinforcement front pillar and a reinforcement side sill according to the present invention, a reinforcement front pillar 10 in which a bend part 13 and a short side part 15 in an L shape in the side view have a hat sectional shape, and a reinforcement side sill 30 having a front part 31 which is fittable in the short side part 15 and has a hat sectional shape are coupled to each other. A front end 33c of the reinforcement side sill 30, which includes an upper end 33a of a wall part 33 on a vehicle body lateral side, abuts against a boundary part 27 between an inner wall surface 17a on the vehicle body lateral side and an inner wall surface 21d on the vehicle body front side of the reinforcement front pillar 10. In the reinforcement front pillar 10 and the reinforcement side sill 30, flange parts, wall parts on the vehicle body upper side and wall parts on the vehicle body lower side are joined to each other, respectively.SELECTED DRAWING: Figure 1

    【課題】本発明は、荷重を効率的に分散伝達させて結合剛性と強度を向上させ、振動を抑制するリンフォースフロントピラーとリンフォースサイドシルの結合構造を提供する。【解決手段】本発明に係るリンフォースフロントピラーとリンフォースサイドシルの結合構造1は、側面視でL字形状における湾曲部13及び短辺部15がハット断面形状のリンフォースフロントピラー10と、短辺部15に嵌入可能でハット断面形状の前方部31を有するリンフォースサイドシル30とが結合されたものであって、リンフォースサイドシル30の車体側方側の壁部33の上端33aを含む前端33cは、リンフォースフロントピラー10の車体側方側の内壁面17aと車体前方側の内壁面21dの境界部27に当接し、リンフォースフロントピラー10とリンフォースサイドシル30は、フランジ部同士、並びに、車体上方側及び下方側それぞれの壁部同士が接合されているものである。【選択図】 図1
