Abstract: A vehicle body structure includes a roof side rail, resin first and second reinforcement members, and a front pillar. The roof side rail is disposed along a vehicle front-rear direction at both vehicle width direction sides of a roof, and is configured, by roof side rail inner and outer panels and a side outer panel, as a beam-shaped vehicle body framework member with a closed hollow cross-section structure including third and fourth closed cross-section portions. The first reinforcement member, as viewed from the side of the vehicle, is disposed to contain a connection position, at a front portion of the roof side rail, to a front roof header disposed along an upper end portion of a windshield glass, and is provided along a length direction of the front portion to fill at least a portion of a space inside a closed hollow cross-section portion at the front portion.

Abstract: In a vehicle, a gusset is provided at a lower end portion of a front pillar, a body wall portion of the gusset is joined to the front pillar, and a bottom wall portion of the gusset is joined to an upper wall portion of a rocker outer reinforcement. Thus, when the front pillar is about to collapse rearward, the upper wall portion supports the bottom wall portion of the gusset from below the vehicle. Therefore, the front pillar is restrained from collapsing. Besides, the rocker outer reinforcement receives, on a surface thereof, a load input from the gusset. Therefore, the load input to the rocker outer reinforcement is dispersed, so the load can be restrained from concentrating.

Abstract: Provided is a vehicle body structure capable of suppressing or preventing folding partway along vehicle body framework with a hollow closed cross-section structure spanning from an upper portion of a front pillar to a front portion of a roof side rail. A rear side reinforcement member (56) configured from a high rigidity foamed member is disposed so as to fill a space inside a fourth closed cross-section portion that is a hollow closed cross-section portion of a front portion (20A) of a roof side rail (20). As viewed from the side of the vehicle, a rear end portion of the rear side reinforcement member 56 is disposed so as to contain a connection position (Y) at the front portion (20A) of the roof side rail (20) to a front roof header (30).
