A body framework construction, includes: a rear seat cross member, extending in a transverse direction of a vehicle, in a rear part of a body in a lower part of a passenger compartment; a dash cross member upper, extending in the transverse direction, in a front part of the passenger compartment; and a backbone, configured into a thin, long shape having a closed cross section, and extending in a longitudinal direction of the vehicle. A front end portion of the backbone is connected to the dash cross member upper via a gusset, and a rear end portion of the backbone is joined to the rear seat cross member. The gusset is deformed more easily than the backbone relative to a force from a front.

Body framework construction

An upper member of a pillar has a substantially U-shaped cross section, and includes first side walls extending substantially in a transverse direction of the vehicle at least at a lower portion, and a connecting plate at a lower end while keeping the U-shaped cross section. A lower member includes a mounting plate opposed to the connecting plate at a lower portion being lower than an upper end, and second side walls extending substantially in the transverse direction at both end portions of the mounting plate in a longitudinal direction of the vehicle. The connecting plate and the mounting plate are welded to each other in a state that they are in abutment with each other, and the first side walls and the second side walls are joined to each other, and the upper member and the lower member are integrally fixed to each other.
