PROBLEM TO BE SOLVED: To provide a vehicle body floor structure capable of improving side impact performance and body rigidity. SOLUTION: In the vehicle body floor structure in which right and left pair of side sills 11, 12 extending in the longitudinal direction of a vehicle body are connected to a front floor panel 13, lower portions of the side sills 11, 12 are directly or indirectly fastened using a reinforcement bar 18 extending in the vehicle width direction. When a side surface impact load acts on one side sill 11 (or the side sill 12), the load is transmitted to the other side sill 12 (or the side sill 11) via the reinforcement bar 18. Specifically, the side surface impact load is distributed to the right and left of the body. Since the right and left side sills 11, 12 are restrained by the reinforcement bar 18, the rigidity of the vehicle body is increased. COPYRIGHT: (C)2011,JPO&INPIT |
