To provide a front pillar reinforcement structure of a vehicle which can inhibit bending deformation of a front pillar during a fine lap collision.SOLUTION: An inner reinforcement 41 of a front pillar 20 has: a body part 42 opening to the inner side as seen in a vehicle width direction on a cross section orthogonal to an axis direction of the front pillar 20 and has a lower coupling part 43 extending from a lower end of the body part 42 and an upper coupling part 44 extending from an upper end of the body part 42. In the inner reinforcement 41, a lower part of the body part 42 includes a bottom wall part 45 along a lower wall part 23a of an outer panel 22 extending along the axis direction of the front pillar 20 and is formed folded so as to form ridge lines N1, N2 at both end parts of the bottom wall part 45. Further, the body part 42 has a flat plate part 46 which connects the bottom wall part 45 to the upper coupling part 44 in a linear manner.SELECTED DRAWING: Figure 2

    【課題】微小ラップ衝突時のフロントピラーの曲げ変形を抑制できる車両のフロントピラー補強構造を提供すること。【解決手段】フロントピラー20のインナリインフォースメント41は、フロントピラー20の軸線方向に直交する断面において車幅方向内側に開口した本体部42を有するとともに、本体部42の下端から延設された下側結合部43、及び本体部42の上端から延設された上側結合部44を有する。インナリインフォースメント41において、本体部42の下部は、フロントピラー20の軸線方向に沿って延びるアウタパネル22の下壁部23aに沿う底壁部45を備えるとともに、底壁部45の両端部に稜線N1,N2が形成されるように折り曲げて形成されている。また、本体部42は、底壁部45と上側結合部44とを直線状に繋ぐ平板部46を有する。【選択図】図2
