摘要

A ridgeline portion is provided at a pillar inner panel such that the ridgeline portion extends substantially vertically from a side sill (a roof side rail), and a load-transmission restraint portion is provided between the ridgeline portion and a welding portion of a pillar end portion where the pillar inner panel is welded to a pillar outer panel or a pillar reinforcement, and the side sill (the roof side rail), the load-transmission restraint portion being configured to have a longitudinal width which is wider than that of a central portion, in the vertical direction, of a center pillar and be substantially flat.
