More specifically, the above-described back panel 8 is formed by bending one panel-shaped member, and includes a downward hanging portion 16 extending in the up-down direction.
The upper bent portion 1 continuously provided on the upper side of the lower hanging portion 16
7 are provided. In the present example, the lower hanging portion 16 of the back panel 8 is configured so that the height in the vertical direction is considerably lower than that of the conventional one, and the bent piece portion 18 is formed at the lower end of the lower hanging portion 16. Has been done. On the other hand, the back panel member 13 is formed by bending a single panel-shaped member similarly to the back panel 8, and is bent and formed to have a substantially U-shaped cross section so as to extend longitudinally in the left-right direction. It has a main body 20 that is formed and has an opening 19 for inserting a lock member at an appropriate position, and flanges 21a and 21b that are bent and formed on both upper and lower edges of the main body 20. Further, the striker bracket 14 is made of a strip material that extends in the left-right direction in a longitudinal shape, and a U-shaped striker 15 is fixed to the left and right center portions thereof. The dimensions and shapes of the back panel member 13 and the striker bracket 14 are substantially the same as those conventionally used.

Thus, with the striker bracket 14 interposed between the back panel 8 and the back panel member 13, these three members 8, 13, 14 are integrally assembled to form the striker portion 12. The striker portion 12 is joined to the rear portion of the floor panel 6. That is, as clearly shown in FIG. 4, the lower flange portion 21b of the back panel member 13 is directly joined to the bending piece 22 at the rear portion of the floor panel 6, and the lower edge portion of the striker bracket 14 is connected to the flange portion 21b. 14b

According to the vehicle rear portion structure of this example having such a structure, the striker portion 12 approaches the floor panel 6 and the floor panel 6 by directly joining the back panel member 13 to the floor panel 6 by welding. The height of the back panel 8 relative to the back panel 8 is relatively low, and as a result, the back panel 8 is less likely to fall in the front-rear direction. In addition to this, since the tail member 25 is arranged at the rear portion of the floor panel 6 to form the closed cross-section portion 26, the rigidity of the rear portion of the floor panel 6 can be improved. Therefore, due to these synergistic effects, the rigidity (strength) of the rear portion of the vehicle body can be significantly improved.

Further, since the striker portion 12 is constructed to be low, the upper opening 3a of the trunk room 9 in the striker portion 12 can be constructed as an opening which extends sufficiently downward as shown in FIG. As a result, it is possible to easily carry out the work of loading and unloading luggage into and from the luggage compartment 3.

FIG. 5 shows another embodiment of the present invention. In this embodiment, the tail member 25 is omitted, and almost the entire lower hanging portion 16 of the back panel 8 is the flange portion of the striker bracket. Spot welding S by joining to 14b
It is designed to be combined in ₃ . According to this example, the rigidity of the striker portion 12 can be secured even if the tail member 25 is omitted.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes can be made based on the technical idea of the present invention. For example, the shapes of the back panel 8 and the back panel member 13 may be any shape as long as they can form the closed cross-section shaped portion 24 of these members. Further, the cross-sectional shape of the closed cross-sectional shape portion 26 formed by the tail member 25, the floor panel 6 and the back panel 8 can be changed as needed.

[0023]
