Problems solved by technology

However, although the rear roof cross member known from Patent Document 2 has a closed cross-section structure and thus achieves high rigidity, it leads to an increase in weight.
Therefore, it is not conducive to reducing the weight of the vehicle body.

Embodiment Construction

[0079] Embodiments of the present invention will be described below with reference to the drawings.

[0080] 【Example】

[0081] The vehicle body rear structure in the embodiment will be described with reference to the drawings. In addition, "front", "rear", "left", "right", "up", and "down" depend on the direction seen from the driver, and Fr indicates the front side, Rr indicates the rear side, and Le indicates On the left side, Ri represents the right side, and CL represents the vehicle width center.

[0082] figure 1 A rear portion of the vehicle 10 is shown. However, the rear end portion of the roof panel 30 is omitted. The vehicle 10 is, for example, a hatchback having a tailgate 13 for opening and closing an opening 12 formed in a rear surface 11 a of a vehicle body 11 . The opening 12 has a substantially rectangular shape and is formed to be large between the left and right rear pillars 14 , 14 . At the rear upper end of the vehicle body 11 , a rear roof cross mem...

Abstract

The invention provides a vehicle body rear structure which can inhibit the weight of a vehicle body and improve rigidity of a roof cross beam. The vehicle body (11) is provided with a rear vehicle roof cross beam (20) which is composed of a longitudinal plate (21) and a lower plate (22) and which has a substantial L-shaped cross section. The cross beam is provided with hinge installation parts (50) for installing hinges (40) for a tail door. The installation part is composed of a bracket (60) and a reinforcing part (70). The bracket is located on an upper surface of the lower plate, and comprises a hinge installation face part (61) where hinges are installed, an extending part (62) extending from the installation face part to the longitudinal plate, and a front-end combination part (66) which is provided at the front end of the extending part and is combined to the longitudinal plate. The reinforcing part is clamped between the lower plate and the installation face part, and is provided with a reinforcing plate (71) combined to the lower surface of the installation face part. A first closed cross-section part (81) is formed through the lower and the reinforcing part. A second closed cross-section part (82) is formed through the longitudinal plate, the lower plate, the extending plate and the reinforcing part. The hinges are installed on the reinforcing plate across the installation face part.

Description

technical field [0001] The present invention relates to an improvement technology of a vehicle body rear structure having a hinge mounting portion for mounting a tailgate hinge on a rear roof beam for supporting a rear end portion of a roof panel. Background technique [0002] Among vehicles, there are models (for example, hatchbacks and hatchbacks) that include a tailgate for opening and closing an opening formed on the rear of the vehicle body. A hinge that supports the tailgate openably and closably is attached to a rear roof cross member via a hinge attachment portion. The rear roof cross member is a member that supports the rear end portion of the roof panel, and extends in the vehicle width direction. The technology of this rear roof cross member is known from patent documents 1-2, for example. [0003] The rear roof cross member known in Patent Document 1 is constituted by a single member having a substantially L-shaped cross-section when the vehicle body is viewed ...
