As disclosed in Japanese Patent Publication No. JP-A-2003-264, there has been already proposed one in which a flat plate portion of a floor panel is provided with a honeycomb structure portion. However, in this proposal, the honeycomb structure portion does not exist in the side sill, and the honeycomb portion of the floor panel is provided. Even if it is structured, it is impossible to reduce the weight and rigidity of the side sill itself. Also, in the floor panel, a considerable amount of plate-shaped flat portion is left at the outer end of the honeycomb structure portion, and since the side sill is integrally connected to the outer end of the plate-shaped flat portion, stress is applied to the connecting portion. Concentration tends to occur, which is disadvantageous in enhancing the mutual reinforcing effect between the side sill and the floor panel. Further, the lower surface of the floor panel and the side sill is formed with a downward recess corresponding to the plate-shaped flat portion across the both surfaces, which is also disadvantageous in terms of aerodynamic characteristics of the lower surface of the panel.
