Claims

[Scope of utility model registration request]

In a front floor pan reinforcement structure that reinforces the front floor pan against input from the front of the vehicle body at the left and right corners of the front floor where the darts panel and the side sill intersect, a corrugated cross section in the vehicle width direction is provided on the lower surface of the front floor pan. a double-panel structure is formed by joining reinforcement hoses having an outer end to a sill outer and a sill inner, and an inner end to a front floor pan and a stringer by three-ply spot welding, respectively;
Furthermore, a reinforcement structure for a front floor pan is characterized in that the front end, the rear end, and the top of the corrugated cross section are joined to the front floor pan by spot welding.
