To provide a vehicle pillar structure that is able to reduce weight while securing strength when an impact load is input from outside the vehicle.SOLUTION: In the structure of a center pillar 10 in which a closed cross-sectional shape is formed continuously in a vehicle vertical direction Dh by joining, at both side edges 13a, an inner panel 11 extending in the vehicle vertical direction Dh and a center pillar RF13 disposed on the vehicle outside Do with respect to the inner panel 11 and whose hat-shaped cross-section is continuous in the vehicle vertical direction Dh. The center pillar RF13 comprises: an external wall portion 13b provided at the top of the hat-shaped cross-section; and a vertical wall portion 13c provided between the external wall portion 13b and each side edge 13a. The vertical wall portion 13c has a curved shape continuous without a corner such that the angle θ of the side edge 13a to the inner panel 11 gradually decreases from the external wall portion 13b to each side edge 13a.SELECTED DRAWING: Figure 2

    【課題】車両外側から衝撃荷重が入力された際の強度を確保しつつ軽量化を図り得る車両用ピラー構造を提供する。【解決手段】車両上下方向Dhに延びるインナーパネル11と、インナーパネル11より車両外側Doに配置されてハット形断面が車両上下方向Dhに連続するセンターピラーRF13と、が両側縁部13aで接合されることで、閉断面形状が車両上下方向Dhに連続して形成されたセンターピラー10の構造であり、センターピラーRF13は、ハット形断面の頂部に設けられた外壁部13bと、外壁部13bと各側縁部13aとの間にそれぞれ設けられた縦壁部13cと、を備え、縦壁部13cは、外壁部13bから各側縁部13aまで、側縁部13aのインナーパネル11に対する角度θが漸減するように角部なく連続した湾曲形状を有している。【選択図】図2
