Abstract: A vehicle body side structure is provided. A vehicle body side structure includes a front fender, a side sill garnish, and an aerodynamic duct. The front fender has a fender recess portion below a first wheel arch portion. The side sill garnish has a second wheel arch portion that faces the fender recess portion at the outer side in the vehicle width direction at interval and faces a rear end of the first wheel arch portion. The aerodynamic duct is interposed between the second wheel arch portion and the fender recess portion. The width of the second wheel arch portion gradually decreases in the front-rear direction of the vehicle body as it extends upward from the front end portion of the side sill garnish to an upper edge.

Abstract: A side structure for a vehicle body, the side structure having: a side rail and a pillar that are provided at sides of door openings; and trim members that are provided to the side rail and the pillar. In the side structure, a pillar inner member is provided to the side rail while the upper end of the pillar inner member overlaps a joint of the side rail, and this forms intersections at which rail flanges and pillar flanges cross. At the intersections, stepped sections are formed at the pillar flanges, and in the rail flanges, recesses are formed at portions corresponding to the stepped sections.
