Therefore, when the pillar is torsionally deformed around its axis during a vehicle side collision (hereinafter simply referred to as “side collision”), the impact beam mounting portion is pressed outward in the vehicle width direction by the pillar. As a result, the extension is easily peeled off from the impact beam mounting portion, and the impact beam may not function as a beam (both-end supported beam). As countermeasures, it may be possible to reinforce the extension or increase the welding strength between the impact beam mounting portion and the extension, but this results in an increase in weight and cost.
