(Effect of the invention) In the automobile back door structure with the above configuration,
The puncture door consists of a rear window section that is rotatably attached to the vehicle body, and a trunk section that is rotatably attached to the rear window section. Alternatively, the entire back door can be opened, which has a great practical effect.

When the flat tire door is fully opened, the Danno 4 member that holds the flat tire door in the fully open position opens the trunk compartment according to the opening operation of the back door when the luggage compartment section is in the open position. Since the back door is automatically moved from the open position to the closed position, it is convenient to close the back door in the same state.

(Embodiments) Hereinafter, a back door structure for an automobile according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The accompanying drawing is a side view of a back door structure according to an embodiment of the present invention.

In this figure, reference numeral 1 indicates the body of an automobile, and a door 2 is provided at the rear opening of the body 1. As shown in FIG.

It has become.

On both sides of the back door rear window section 3 in the vicinity of the trunk section, arms 6.7 are rotatably mounted on a shaft 8 at one end of each arm on the rear side. The knock door trunk section 4 is supported by this arm 6.7, and thus the pack door trunk section 4 is rotatable relative to the knock door rear window section 3.

On the left and right sides of the vehicle body 1 are the 7th and 1st Dan/49, respectively.
．． 10 is pivotally mounted at one end thereof by an axle 11. The other end of the first damper 9 is connected to the arm 6, and
The other ends of the arms 7 are pivotally connected to the arms 7, respectively. The above No. Kodanno J? 1o, when the pack door trunk part 4 is rotated with respect to the back door rear window part 3 from the closed position shown by the solid line in the figure and moved to the open position shown by the broken line in the figure, the pack door trunk part 4 This acts to hold the opening in this open position. The first Dan/4'IO further has a stopper to prevent it from being extended beyond a predetermined value, so that when the puncture door trunk section 4 is in the open position,
