PROBLEM TO BE SOLVED: To improve occupant protection performance with respect to a vehicle side collision load, related to a side sill reinforcing structure.SOLUTION: In a reinforcing structure of a side sill 9 having a closed cross section which is formed by laminating an inner member 4 and an outer member 1B, and forming a lower frame of a vehicle door opening, a reinforcing member 5 is gripped between the inner member 4 and the outer member 1B, and arranged in the closed cross section. A cross section of the reinforcing member 5 is formed into a hat shape which protrudes to the outside of a vehicle. Furthermore, a support member 6 is fixed to a side face 5B and a bottom face 5C of the reinforcing member 5, and the reinforcing member 5 is reinforced. A lower face 6A fixed to the bottom face 5C and extended to the outside of the vehicle rather than the side face 5B along an extension face of the bottom face 5C is formed at the support member 6.SELECTED DRAWING: Figure 5 |
