Provided is a structure for a side portion of a vehicle body, the structure reducing the weight and, at the same time, achieving required collision performance. A rocker member (3) is configured from an outer panel (11), an inner panel (12) which is disposed on the inside of the outer panel (11) in the width direction of the vehicle, and a backup panel (13) which is disposed on the inside of the inner panel (12) in the width direction of the vehicle. A backup panel center protrusion (50) which protrudes inward in the width direction of the vehicle is provided on the center of the backup panel (13) in the front-rear direction of the vehicle, an outer panel bead center section (22) which is recessed inward in the width direction of the vehicle is formed in the outer panel (11), and an inner panel bead center section (39) which is recessed outward in the width direction of the vehicle is formed in the inner panel (12). As a result of the configuration, the rigidity in the width direction of the vehicle is increased. Also, an inner panel bead end section (44) which is recessed outward in the width direction of the vehicle is formed in the inner panel (12), and a backup panel bead end section (64) which protrudes inward in the width direction of the vehicle is formed on the backup panel (13). As a result, the rigidity in the front-rear direction of the vehicle is increased. |
