<p>An upper end joint portion which has increased rigidity by being bent in a rectangular wave shape and is joined to a roof side rail reinforcement is formed at an upper end portion of a center pillar reinforcement. Then, in the roof side rail reinforcement, longitudinal beads and extending in a direction orthogonal to a vehicle front-back direction are formed further on only the rear side in the vehicle front-back direction than a front-side end edge in the vehicle front-back direction in the upper end joint portion in the upper side in a vehicle up-and-down direction of a joint portion to the center pillar reinforcement.</p> |
