３３とよりなるものが使用されている。2. Description of the Related Art A description will be given with reference to FIGS. Attached to the door sash and elastically contacting the opening edge of the body, door sash 21, body side sealing surface 11 and drip molding 1
Conventional weather strip 30 for sealing between the two
As shown in FIGS. 1 to 4, the door sash 21
A base portion 31 fitted to the retainer portion 22 and a hollow portion which is integrally connected to the inside and the outside of the base portion 31 and elastically contacts the body side sealing surface 11 and the drip molding 12 at the opening edge of the body panel. A seal portion 32 and a seal lip 33 are used.

中空シール部３２内にブリッジ３５を設けていた。For the weather strip, it is required that the transmitted sound is low and that the door closing property and the sealing (water leakage) property are good. Therefore, as shown in FIG. As shown in FIG.
And the body-side sealing surface 11 with which the hollow seal portion 32 of the weather strip 30 abuts is enlarged from θ 1 to θ 2 to widen the seal width L with the hollow seal portion 32, or to the weather strip 30 side. As shown in FIG.
The bridge 35 was provided in the hollow seal portion 32.

に変化し、ドア閉じ性が悪化する。However, the conventional weather strip 30 has the following problems. That is, when the bridge 35 is provided in the hollow seal portion 32, as shown in FIG. 5, when the bridge 35 compresses the hollow seal portion 32, the so-called hollow bottom portion of the hollow seal portion 32 is quickly abutted against the hollow seal portion 32. As shown in, the load when the door 20 is closed changes abruptly, and the door closeability deteriorates.

The distribution of the force in 2 is biased to the upper and lower parts, the surface pressure Q applied to the middle part becomes low, and the gap S between the body side seal surface 11 and
Occurs or the surface pressure becomes zero, the seal width decreases and the transmitted sound increases.

部から水Ｊを導き易くなる。Further, as shown in FIGS. 7 and 9, the surface pressure distribution in the hollow seal portion 32 is biased to one side, and the highest point of surface pressure may come to the lower part on the indoor side, which deteriorates the sealing performance. It becomes easy to guide the water J from the outside.
【０００７】このことから、上記問題点を回避するた
め、従来、ドア２０の閉じ性とシール性との背反事象を
２者択一で行っていた。Therefore, in order to avoid the above-mentioned problems, conventionally, the trade-off between the closing property and the sealing property of the door 20 has been performed by two alternatives.

を両立させることが困難であることである。The problem to be solved is that the conventional weather strip 30 has a poor door closing property and a seal width L with the body side sealing surface 11.
Is small, the transmitted sound is large, the sealing property is poor, it is easy to introduce the water J from the outside, and it is difficult to achieve both the sealing property and the door closing property.

A weather strip 30 comprising a hollow seal portion 32 and a seal lip 33 which are elastically brought into contact with the edge 10, and the hollow seal portion 32 and the upper surface from the hollow seal portion 32 to the root of the seal lip 33 are attached to the door 2
It is formed in a substantially W-shaped cross-section along the zero entry trajectory K.

Is a hollow seal portion integrally connected to the inner side of the base portion 31 and 33 is a seal lip integrally connected to the outdoor side of the base portion 31. It is elastically contacted with the body side sealing surface 11 and the drip molding 12. Moreover, the hollow seal portion 32
And the upper surface from the hollow seal portion 32 to the root of the seal lip 33 along the entrance locus K of the door 20 in section W
It is shaped like a letter.

に、透過音が著しく低減される。Since the hollow seal portion 32 and the upper surface from the hollow seal portion 32 to the root of the seal lip 33 are formed in a substantially W shape, when the door 20 is closed, the hollow seal portion 3 is formed.
The inner surface of 2 makes elastic contact with the sealing surface 11 of the body 10,
When pressed by it, the bent portion of the substantially W-shaped upper surface is bent and deformed at the fold. Therefore, the load applied to the hollow seal portion 32 is dispersed in a wide range, a substantially uniform surface pressure Q is applied within the variation of the building, and the gap S and the point of zero surface pressure do not occur, and the hollow seal portion 32 is Since the highest point of the surface pressure is formed on the outside of the room, the effect of preventing water leakage is increased and the transmitted sound is significantly reduced.

る。Since there is no bridge in the hollow seal portion 32, as shown in FIG. 5, the so-called hollow seal portion 32 is used.
12 does not occur, the load when the door 20 is closed gradually changes, and the door closeability is good, as shown in FIG.
