Problems solved by technology

[0008] However, the torsional rigidity of the vehicle body is lowered because the open end of the vehicle body becomes a free end and the surface rigidity of the body panel cannot be ensured sufficiently, and the torsional rigidity of the vehicle body cannot be sufficiently improved only by reinforcing the pillars with reinforcing members.

Abstract

A connection gusset 6 for connecting an end panel 3 and a rear wheel house 4 is arranged at a vehicle front side of the end panel 3. The connection gusset 6 is constituted by a plate-like panel member and forms a member part 61 of a hat-like cross section extending in the longitudinal direction of the vehicle at the inner side of a cabin. The purpose of the invention is to provide a rear vehicle body structure for a vehicle capable of exactly preventing reduction of torsional rigidity of the vehicle body in the vehicle in which an opening corresponding to a back door is provided on a rear wall of the vehicle body.

Description

technical field [0001] The present invention relates to a vehicle rear body structure, specifically, to a vehicle rear body structure that improves the torsional rigidity of the vehicle body. Background technique [0002] Conventionally, such a proposal has been made in the following Patent Document 1 as a technique for improving the rigidity of a vehicle. [0003] In this patent document 1 (Japanese Patent Laid-Open Publication No. 2001-328562), in a vehicle that supports a spare tire on a rear door (rear gate), in order to increase the rigidity of the pillar supporting the rear door, a reinforcement extending in the front-rear direction of the vehicle is added. The member is provided inside the side wall of the vehicle body, and the rear end of the reinforcing member is connected to a pillar that supports the rear door. [0004] However, the body constituting the vehicle is provided with several openings corresponding to the doors and the like, and if such openings are la...
