Vehicle side portion structure with two parts reinforcing B-pillar member for improved side crash worthiness

A vehicle side portion structure is provided that can suppress or prevent separation at a joined portion between members at a time of a vehicle side collision. At a pillar outer reinforcement (38), a reinforcement upper (44) and a reinforcement lower (46) are joined at a joined portion (56) by spot welding or the like. A hinge reinforcement (40) is, in a state of spanning over this joined portion (56), joined to the reinforcement upper (44) and the reinforcement lower (46). Therefore, when tensile force is applied to the pillar outer reinforcement (38), shearing force that acts on the joined portion (56) can be reduced by reaction force obtained from the hinge reinforcement (40). Due thereto, at a time of a vehicle side collision, separation at the joined portion (56) can be suppressed or prevented. 提供了种车辆侧部结构，其在车辆侧面碰撞时能够抑制或防止在构件之间的接合部处的分离。在柱外加强件(38)处，加强件上部(44)和加强件下部(46)通过点焊或类似方式在接合部(56)处接合。铰链加强件(40)在跨越该接合部(56)的状态下接合至加强件上部(44)和加强件下部(46)。因此，当拉伸力施加至柱外加强件(38)时，作用在接合部(56)上的剪力可以通过从铰链加强件(40)获得的反作用力减小。由此，在车辆侧面碰撞时，能够
