PROBLEM TO BE SOLVED: To sufficiently exhibit a reinforcement effect by integrally constituting a bulk head part with a reinforcement and bring the bulk head part into another body configuration to a pillar inner, and thereby reduce a body weight and reduce the number of parts without being affected by mutual materials or a board thickness.SOLUTION: A reinforcement 4 disposed in a closed cross section 2A of a side sill 2 constituted by a sill inner 2a and a sill outer 2b is configured by having a shear plane 5 planarly opposed to the sill inner 2a, and a pair of bulk head parts 7 for respectively defining the vehicle body longitudinal direction of the closed cross section by the shear plane 5 and the sill inner 2a is integrally formed to the reinforcement 4, and thereby the reinforcement 4 is joined and disposed in the pillar inner 1a and the sill inner 2a.SELECTED DRAWING: Figure 1 |
