面に接する。 A weather strip 4 consisting of a base portion 41 and a lip-shaped seal portion 42 is attached to the roof side 11 by the base portion 41. This weather strip 4 extends from the roof side 11 to the front pillar 1.
It is installed along 2. The seal portion 42 extends toward the outside of the vehicle, and its tip contacts the inner surface of the protruding edge 31 of the door sash 3.

By the way, when the automobile is running at high speed, negative pressure is generated on the outside of the door glass 6 and the door sash 3, and the door glass 6 and the door sash 3 are sucked out in a direction perpendicular to the surface of the door glass 6 (in the direction of the arrow X). As a result, the sealing force of the weather strips 4 and 5 decreases, causing air leakage from the interior of the vehicle to the exterior of the vehicle, which may result in air suction noise.

As illustrated in FIG. 1, along the roof side 11 of the body opening, the root part faces toward the outer periphery of the door sash 3, the tip half thereof is bent toward the interior of the vehicle, and the lower surface of the tip faces the outer periphery of the door sash 3. A weather strip 4 is attached having a lip-shaped seal portion 43 having a dogleg-shaped cross section and making surface contact with the surface. This weather strip 4 extends from the roof side 11 along the front pillar 12 (FIG. 1).

When a car is running at high speed, negative pressure is generated on the outside of the door glass 6 and door sash 3, and the door moves in the direction of arrow X.
It is sucked out in the direction. At this time, the air in the vehicle interior acts in the direction of exiting the vehicle, pushing the seal portion 43 of the weather strip 4 toward the exterior of the vehicle. As a result, the lower surface of the tip of the seal portion 43 is pressed against the outer peripheral surface of the door sash 3. This pressing force increases as the above-mentioned negative pressure increases and therefore the door suction increases. Therefore, even if the door is sucked out, air leakage to the outside of the vehicle is prevented.
以下、本発明の実施例を第４図に示す従来例と

ある。 In the first embodiment shown in FIG. 1, a weather strip 4 is attached to the door opening of the automobile body from the roof side 11 to the front pillar 12 (FIG. 5). The weather strip 4 includes a solid rubber base 41, a conventional type first seal portion 42 that extends outward from the base 41 and comes into contact with the inner surface of the protruding edge 31 of the door sash 3, and the base 41.
It consists of a novel second seal portion 43 extending from the door sash 3 toward the outer circumferential surface of the door sash 3. both seal parts 42,
43 is sponge rubber. The outer peripheral surface of the door sash 3 is an inclined surface rising toward the outside of the vehicle. Second
The seal portion 43 has a root portion that is perpendicular to the outer peripheral surface of the door sash 3 and faces slightly outward from the vehicle, a tip half that is bent toward the interior of the vehicle, and has a dogleg-shaped cross section as a whole. makes surface contact with the outer peripheral surface of. The other structure is the same as the conventional example shown in FIG.

ドアサツシ３側に取付けてある。 FIG. 2 shows a second embodiment, in which the second seal part 43 of the weather strip 4 has the first point in that the tip branches into small lips 43a and 43b, forming a double seal. This is different from the above embodiment shown in the figure. In this embodiment, the hollow seal portion 5 is attached to the door sash 3 side.

で先端部はく字形となつている。 FIG. 3 shows a third embodiment, in which the weather strip 4 is integrated with the opening trim 8, extends outward from the outer upper end of the trim 8 along the roof side 11, and has a front half bent downward. The door sash 3 extends substantially perpendicularly to the outer peripheral surface of the door sash 3, and its tip is bent toward the interior of the vehicle, with an L-shaped cross section as a whole and a dogleg shape.

設けてある。 Note that the trim 8 is formed with another hollow seal portion 9, which is of a bend type that bends like a lip when the door sash 3 is pressed in order to reduce the door closing force. Also weather strip 5
is provided at a position further outside the vehicle than the weather strip 4.

低下する。 In the seal structure constructed as described above, when the automobile is running at high speed, the door glass 6 and the door sash 3 are sucked out in the direction of the arrow X by negative pressure outside the vehicle. This reduces the sealing force of the weather strip 5.
このとき、車室内の空気は車外に吸出されよう

アは水平方向（Ｙ方向）に開閉されるので、シー
ル部４３がドア開閉の障害とはならない。 At this time, the air inside the vehicle tries to be sucked out of the vehicle and pushes the weather strip 4 toward the exterior of the vehicle. Since the weather strip 4 has a dogleg-shaped cross section to receive this air pressure, the lower surface of the tip is pressed against the outer circumferential surface of the door sash 3, which forms an inclined surface rising toward the outside of the vehicle. This pressing force becomes stronger as the negative pressure becomes larger and therefore the door suction becomes larger. Note that since the door is opened and closed in the horizontal direction (Y direction), the seal portion 43 does not become an obstacle to opening and closing the door.

As described above, in the present invention, the weather strip 4 is provided with a lip-shaped seal portion 43 having a dogleg-shaped cross section and whose tip is in surface contact with the outer peripheral surface of the door sash. The sealing force is strengthened as the door is sucked out, so that air leakage and the noise caused by the air being sucked out can be prevented. The effect is the second
If the tip of the seal portion 43 is branched to form a double seal structure as in the embodiment shown in the figure, it will be even larger.
