As shown in FIG.
The door inner panel 1a to which the door trim 1c is attached is
It is bent to the outside of the cabin to form a door bottom surface 10 and is joined to the door outer panel 1b. When the front door 1 is in the closed state, the door bottom surface 10 has weather strips 8 on both sides,
It faces the upper surface of the rocker panel 9 below the scuff plate 9d to which the scuff plate 9d is attached between 8a. The front door 1 is of an inner seal type, and is provided with a door weather strip 8 in an auxiliary manner. It is designed to be sealed to the outside.

According to the present invention, in the gap caused by mounting components on the door trim 1c, an air leakage pad is not attached and is left as it is. The rear end of the door bottom surface 10 has a width of 5 mm in the front-rear direction and a width of 30 mm in the vehicle width direction.
Are formed, and an opening of about 10 cm ² is formed in total. As a result, the exhaust port 11 has an area that is sufficiently larger than the clearance area on the surface of the door trim 1c, and communicates with the outside air below the exhaust port 11 to form a negative pressure area during traveling. Therefore, the traveling wind that has entered the front door 1 through the working hole or the check arm opening in the front end face changes the conventional path toward the gap generated in the door trim 1c, and faces the rear end of the door bottom face 10, The air is exhausted from the exhaust port 11 into the gap between the door bottom surface 10 and the rocker panel 9 and exhausted to the outside of the vehicle.

FIG. 3 shows another embodiment for a hardtop vehicle. The door is of an outer seal type in which the interior of the vehicle is sealed to the outside by a door weather strip 8, and an opening weather strip 8a is provided at a portion corresponding to a lower half door panel of the door opening. When the terminals are closed, the terminals are in close contact with each other, so that the space between the door bottom surface 10 and the rocker panel upper surface 9a does not communicate with the outside air.

In view of this, an exhaust port 21 into the vehicle interior is provided in the lower end region of the rear end portion of the door inner panel 1a.
This exhaust port is formed by hanging the lower end of the door trim 1c downward without directly contacting the door inner panel 1a for about 20 cm, leaving the rear edge 23a, leaving the rear edge 23a. The gap between the raised flange portion 9b and the seal portion 9c on the vehicle interior side is 5 m.
