A rear opening for opening the passenger compartment and the luggage room is formed, and a back door that opens and closes the passenger compartment side of the rear opening is swingably supported in the vehicle body. The luggage door is supported to open and close freely on the luggage room side, and when loading small luggage into the luggage room, only the luggage door is opened, and when loading large luggage, the luggage door and the back door are integrated. A device has been proposed that can be opened to open the entire rear opening.

However, in the above-described automobile, a weather strip is disposed on the opening edge of the rear opening closed by the back door and the luggage door to prevent rainwater etc. from entering the luggage room. In addition, since the boundary between the rear end of the back door and the front end of the luggage door is located above the luggage room, there is a risk that rainwater passing through the gap at the boundary may enter the luggage room. Therefore, as seen in the above publication, a rain guide is provided at the rear end of the back door that extends across the entire width of the vehicle, and a weather strip that comes into contact with the luggage door is provided on the rear vertical wall of the rain guide. are doing.

(Problem to be Solved by the Invention) In the above-described automobile, when the back door and the luggage door are closed, the space between the rear vertical wall of the rain guide and the front edge of the luggage door and the opening edge of the rear opening At the point where it intersects with
A gap is created that opens the luggage room to the outside of the vehicle, and it is difficult to reliably seal this gap using only the weather strips.

Therefore, conventionally, as seen in the above-mentioned publication, a block-shaped sealing material that closes the gap is separately formed, and the sealing material is attached to the opening edge of the rear opening near the rear vertical wall of the rain guide. They are fixed at the intersecting positions to close the gap, but in the above car body structure,
Since the sealing material must be formed separately, the number of parts increases accordingly, and furthermore, there are problems such as the need for work to secure the sealing material to the back door.

This invention was developed in view of the above circumstances.
The purpose is to be able to reliably close the luggage room with an extremely simple configuration, improve the appearance of the luggage room, and prevent damage to luggage when loading and unloading the luggage into the room. The objective is to provide a rear body structure that allows for

(Means for Solving the Problems) Accordingly, the present invention forms a rear opening for opening the passenger compartment and the luggage room in the rear part of the vehicle body of an automobile provided with a luggage room at the rear of the vehicle compartment, and at the same time, in the vehicle body, In the automobile, a back door that opens and closes the passenger compartment side of the rear opening is swingably supported, and a luggage door that opens and closes the luggage room side of the opening is swingably supported at the rear end of the back door. A first weather strip is disposed at the opening edge of the opening, and a rain guide is disposed at the rear edge of the back door, the rain guide extending across the front width of the luggage door in the vehicle width direction;
A second weather strip is provided on the rear vertical wall of the rain guide and extends over the entire length of the rear vertical wall and comes into contact with the front edge of the luggage door when the luggage door is closed. The second weather strip bulges rearward over the entire length of the second weather strip, and when the luggage door is closed, the upper end and rear edge of the second weather strip come into contact with the second weather strip on the luggage door. The rain guide continuously abuts rearward from the rear vertical wall, and its lower end extends to approximately the same height as the lower end of the rear vertical wall and abuts on the first weather strip, and the rear vertical wall of the rain guide and the luggage door The present invention is characterized in that an elastically deformable sealing portion having a hollow cross section and capable of closing a gap at a portion intersecting with the opening edge of the rear opening is integrally formed between the front edge portion and the front edge portion.

(Function) According to the present invention, when the door is closed, the seal portion prevents a gap between the rear vertical wall of the rain guide and the front edge of the luggage door at a portion that intersects with the opening edge of the rear opening. Of course, since the seal portion is formed over the entire length of the second weather strip, the upper end of the second weather strip is closed when the luggage door is closed. The front edge of the luggage door can be reliably sealed over the entire width in the vehicle width direction by the upper end of the second weather strip and at least the upper end of the sealing part without accidentally falling down. As a whole, it is possible to reliably prevent rainwater etc. from entering into the luggage room, and furthermore, the second weather strip provided with the seal portion can be manufactured at low cost by extrusion molding.

Further, according to the present invention, since the rear vertical wall of the rain guide is reliably covered by the seal portion,
The appearance of the luggage room is improved, and when loading and unloading luggage into the luggage room, the luggage can be elastically received by the hollow seal portion without directly colliding with the rear vertical wall. This reduces the risk of damage to cargo during loading and unloading.
