Provided is an improved automotive vehicle body structure which is light in weight but demonstrates an improved mechanical strength at the time of a frontal collision. A pair of front side frames (4) extend in a fore-and-aft direction in a mutually spaced relationship in a front part of a vehicle body, and a pair of floor frames (6) having forward ends joined to rear ends of the corresponding front side frames, respectively, and extending in the fore-and-aft direction. A front cross member (13) is provided with a pair of lateral ends that are joined to inboard sides of the rear end portions of the corresponding front side frames, and is given with an arch shape such that a fore-and-aft dimension of the front cross member diminishes from each side end thereof toward a middle part thereof. A middle cross member (14) is placed some distance behind the front cross member and extends across the floor frames. Tunnel frames extend in a fore-and-aft direction in a laterally centrally part of the vehicle body to join a dashboard lower panel (3), front cross member (13) and middle cross member (14) to one another.
