Abstract

The present invention provides a back structure of a vehicle body, capable of generating a great resisting force against collision, and restraining number and weight of parts. The back structure of the vehicle body includes left and right back vehicle frames (14, 16) for supporting a cantalever extending on the back of the vehicle body front and back; a rear cross beam (17) arranged on the back vehicle frames (14, 16) in a striding mode, the rear cross beam (17) and a center cross beam (13) arranged on front of the rear cross beam (17) are linked by a box protection lever (18) extending back and front and bending downwards, a back end part (18d) of the box protection lever (18) is covered by a support bracket (27) from the lower side and is fastened on the rear cross beam (17) through the support bracket (27).

Description

technical field [0001] The present invention relates to a rear body structure improved for rear collision. Background technique [0002] As the conventional rear structure of the vehicle body, a structure in which the front and rear of the lower part of the vehicle body are connected by a retaining band for a fuel tank (for example, refer to Patent Document 1.) and a structure in which the lower part of the vehicle body is arranged inclined with respect to the front and rear direction are known ( For example, refer to Patent Document 2.). [0003] with the following Figure 9 For Patent Document 1 Figure 9 Be explained. Therein, the reference numerals have been converted. [0004] A floor frame 102 extending front and rear is attached to the lower surface of the front floor portion 101 of the vehicle body, and a cross member 104 extending in the vehicle width direction is attached to the lower portion of a rear floor portion 103 arranged behind the front floor portion 101...
