使用を可能にしたものである。(Structure of the Invention) In order to achieve the above object, in the present invention, the front end of the upper surface 8B of the bumper is located on the d■1 side from the lower end of the back door, and is located below the most protruding part of the rear end of the rear cross member. The vehicle body structure at the rear of the automobile has a #4f feature in which a guide surface is formed downward from the most protruding part of the rear end of the rear cross member to guide the front end of the "-" surface of the bumper downward in the event of a collision. , Even if the /Sumper deforms in the event of a rear-end collision, the L side part will not deform to the side, /
- Not only does it not interfere with the door, but it also does not intrude into the opening of the vehicle body, and is guided by the guide surface of the rear crossmen/＼ to deform downward, allowing the back door to be opened and closed, and the rear of the vehicle body is also in relatively good condition. This allows for continued use.
