VEHICLE BODY STRUCTURE

Abstract:

To actively absorb impact energy by a bead and reduce weight. A vehicle body rear structure 1 of an embodiment includes rear floor panels 2 and 3 formed by a steel plate having a tensile strength of 440 MPa or more. The rear floor panels 2 and 3 have beads 13 and 23 extending in a predetermined direction over an entire surface, and the direction in which the beads 13 and 23 extend and the type of the beads 13 and 23 are set so as to reduce a difference between a peak load and an average load at the time of collision.
