PURPOSE: A center pillar reinforcement structure is provided to reduce invasion rate of a vehicle body in corrosion of a side surface and to increase rigidity of a center pillar outer reinf. CONSTITUTION: A center pillar reinforcement structure comprises a center outer panel, a center inner panel, a center pillar outer reinf, and a center pillar inner reinf(400). The center outer panel is included in the outside of a vehicle. The center inner panel is included inside of the vehicle and is connected to the center outer panel with a flange. The center pillar outer reinf and the center pillar inner reinf are included between the center inner panel and the center outer panel and reinforce rigidity of the center inner panel and the center outer panel. The center pillar inner reinf differently applies a connection part of the upper part and the lower part so that individually supports stress differently applied to the upper part and the lower part of the center outer panel and the center inner panel. |
