Abstract:
To reduce tensile stress generated on a flange portion as a welded portion at the time of a side collision by setting the position of a bottom surface of a recessed bead for rigidity improvement closer to the flange portion as the welded portion than a neutral axis and prevent or suppress welding fracture.SOLUTION: A vehicle center pillar structure 10 is formed in an elongated shape having a protruded curvature shape to a direction in which a load acts on a portion of an area in a longer direction, and includes a pillar outer member 12 having a hat shape in cross-section and a pillar inner member 14 closing the opening side. Respective flange portions 28, 36 are integrally connected by welding. A recessed bead 30 in a longer direction is formed on a ceiling portion 24 of the pillar outer member 12. And, the recessed bead 30 formed on the ceiling portion 24 of the pillar outer member 12 is formed such that a ridge line 42 is formed on a bottom surface portion 40. The position in which the ridge line 42 is formed is located on the vehicle inner side from a neutral axis N of the entire vehicle center pillar structure 10.SELECTED DRAWING: Figure 8
