Description

[Detailed description of the invention] This invention relates to a seal structure for body parts of automobiles and the like.

In a ventilation structure installed in the body panel of an automobile to exchange indoor air, a plate-shaped patch plate with a ventilation hole is installed inside the ventilation hole of the body panel to allow only air to pass through and prevent rainwater from entering. There is something that is made to stick to it.

The ventilation openings on the car body panel and the ventilation openings on the backing plate are arranged at different positions, so that the air inside the car can freely circulate outside the car, but the rainwater from outside the car does not flow into the inside of the car. .

At this time, a sealing material is buried in the bonding surface between the vehicle body panel and the backing plate to prevent rainwater from flowing in there, and the present invention was devised to improve the sealing performance.

Next, the structure will be explained with reference to embodiments shown in the drawings.

This is a ventilation port 2 provided in a quarter panel 1 of an automobile, and a dish-shaped patch plate 5 is fixed to the inside of the outer panel 3 so as to separate a space between an outer panel 3 and an inner panel 4 of the vehicle body. It is.

Each plate is provided with an air circulation hole, the outer panel 3 has a large ventilation hole 3a, the inner panel 4 has several airflow holes 4a, and the backing plate 5 has several ventilation holes 5a. It is.

The flow ports on each plate are located at different positions.

Further, a grill 6 is fixed to the outside of the ventilation port 3a of the outer panel 3, and this grill 6 is formed, for example, in the form of horizontal bars or grids to prevent foreign matter from entering from outside the vehicle, and also to prevent foreign matter from entering the ventilation port portion 2. It is designed to improve the appearance of the outside of the car.

A string-shaped sealing material 7 is embedded in the fixing surface 5b of the backing plate 5 to the outer panel 3, and the string-shaped sealing material 7 goes around once along the fixing surface 5b.

That is, the annular bead 5 surrounding the fixing surface 5b of the backing plate 5
c is provided, a sealing material 7 is embedded in this, and the backing plate 5 is fixed to the inside of the outer panel 3.

Since this sealing material 7 is string-shaped, it has a starting end 7a and a terminal end 7b, but when buried, the starting end 7a
If there is a gap at the joint between the end portion 7b and the end portion 7b, rainwater or the like will pass through the gap, impairing the sealing performance.

Therefore, the starting end 7a and the ending end 7b are arranged closely side by side on the fixing surface 5b, and for this purpose, the annular bead 5c of the backing plate 5 is provided with a locally widened wide part 5d, and the starting end 7a and the terminal end 7b are closely arranged side by side on the fixing surface 5b. Starting end 7a and ending end 7 of the sealing material 7 arranged side by side
It is designed to store b.

As mentioned above, the present invention is designed so that the starting end and the ending end of the sealing material, which is buried in a circumferential manner in the fixing surface of the patch plate provided inside the vehicle body panel, are housed closely side by side on the fixing surface. This has the effect of preventing rainwater from entering through the joint and improving the sealing performance.
