The center support panel and the rocker panel could be combined in the same manner as described above, but in this case, when a shock was applied from the side of the vehicle, bending occurred, resulting in a poor shock absorption rate. For example, when the impact is applied from the side, the rocker panel and the center support panel form a self-deformation and absorb the shock. The most ideal form of deformation is the rocker panel and the center support panel are deformed and compressed into a corrugated pipe. to be. However, in the prior art, a portion having a high strength is formed locally at the portion where the center support panel and the rocker panel are coupled, so that uniform deformation does not occur as a whole. The stress is concentrated and the part is bent to one side to reduce the shock absorption rate, as a result of which there was a problem that increases the passenger injuries.

In addition, when the center support panel is fixed to the rocker panel by the above method, it is very inconvenient for the operator to fix the center support panel to the rocker panel. That is, in order to fix the center support panel to the rocker panel, the inner panel should be fixed by spot welding the outer panel to the outer panel while the lower end of the center support panel is temporarily fastened to the engaging groove of the outer panel. In addition to being very inconvenient to fix the panel, workability and productivity were a factor.

The present invention has been devised in view of the above problems, and its purpose is to improve the shock absorption rate of the center support panel and the rocker panel to prevent the center support panel and the rocker panel from bending during side impact and at the same time easily The present invention provides a coupling structure of the center support panel and the rocker panel to fix the support panel to the rocker panel to improve workability and productivity.
