部15bより下方に突出している。In FIG. 1 to FIG. 3, 11 is a side member,
The cross section is U-shaped, and the flange portions 12 and 13 are provided on the upper opening edge and the opening edge of the rear end portion. A rear floor 14 is placed on the upper surface of the side member 11 and welded to the flange portion 12. A reinforcing member 15 formed by drawing a sheet metal is attached to a lower portion of the rear end portion of the side member 11. The reinforcing member 15 has a U-shaped cross section that is upward when viewed from the front, and has both side wall portions 15
It has a, 15a and a bottom wall portion 15b. Furthermore, a front wall portion 15c that is inclined is provided in the front portion, an opening portion 15d is provided in the rear portion, and a flange portion 15e is provided at the opening edge of the opening portion 15d. The upper edge portions of both side wall portions 15a, 15a of the reinforcing member 15 are welded to both side portions of the side member 11, the front wall portion 15c is welded to the bottom portion of the side member 11, and the flange portion 15e. Is a side member 11
Is formed flush with the flange portion 13 of the. Therefore,
A reinforcing member 15 is provided so as to project from a lower portion of the rear end portion of the side member 11, and the lower portion of the side member 11 is configured by the reinforcing member 15 in a box cross section. Further, a U-shaped towing hook 1 is provided on the front wall portion 15c of the reinforcing member 15.
6 is welded, and its bent portion 16a projects downward from the bottom wall portion 15b of the reinforcing member 15.

厚を厚くする必要がなく、また小形化も図れる。With such a configuration, when a tow rope 18 is hooked on the tow hook 16 to tow a failed vehicle or the like, the tow load is dispersedly received by the side member 11 and the floor side 17 from the reinforcing member 15. Therefore, no concentrated load is applied to the reinforcing member 15 and its welded portion. As a result, it is not necessary to increase the plate thickness of the reinforcing member 15, and the size can be reduced.
