On the other hand, a shielding rib 12 is provided that protrudes from the 1LF'E side wall 6 in the direction of the door crow 5, and extends approximately downward from the outer end of the outer lip 9. It has a structure in which a shielding lip 113 is provided in a protruding manner. (Jitsukai 1977
According to the door weather strip 3a shown in FIG. 4, according to Publication No. 24116, when the door glass 5 is raised, the main lip 18 and the storming trigger t2.13 are virtual! ! i! It is deformed to the position shown in 14° 14, and the tips of the door glasses 12 and 13 are in contact with the front and rear sides of the door glass 5 to improve airtightness inside and outside the vehicle when the door glass 5 is closed. .

Problems to be Solved by the Invention However, according to the conventional example shown in FIG. There is the problem that it doesn't look good because he can't participate, and
If the main rib 8 does not have sufficient flexibility, the door glass 5 will rise, resulting in insufficient adhesion between the upper end surface 5a of the door glass 5 and the main rib 8, resulting in a decrease in watertightness. are doing. - In the case of the conventional example shown in Figure 4, when the door glass 5 rises, ill & livp 12
Although the tip of the clip 1213 comes into contact with the surface of the door glass 5, a space 15, 16 is created between the da shielding clip 1213 and the door glass 5. There is a disadvantage that moisture tends to accumulate in the spaces 15 and 16. Also, door glass 5 and shielding vup 12,
Since the wire seal is mainly purchased using the tip end of the wire seal, it has the disadvantage that the seal is likely to break in the middle of the wire seal due to variations in the dimensions of the product.

Therefore, the present invention solves the problems of the conventional subshell door type east door weather strip as described above.
To provide a door weather strip which can improve air resistance and moisture resistance as well as the flatness between the door glass surface and the weather strip 1.

Ninth means for solving the problem: A small protrusion is formed at the tip of the outer lip extending diagonally downward from the outside of the vehicle from the base of the base, and near the outside of the area where the upper end of the door glass comes into contact; On the inner side of the outer lip of the hollow part and on the outer side of the boundary between the small protrusion and the main lip, there is a crease 1r that can read the bending characteristic of the outer lip, and is made of cedar.

As the working window glass rises, the upper end of the window glass also comes into contact with the main rib 1 located on the inside of the vehicle in the vicinity of the small protrusion, thereby deforming the main lip. At this time, due to the action of the folding groove formed on the inner side of the outer lip of the hollow part and the outer side of the boundary between the small protrusion and the main lip, the outer y1 is bent at an acute angle toward the windshield, and the upper end surface of the windshield is This improves the adhesion between the main lip and the main lip, and prevents water channels from forming between the two.

EXAMPLE Hereinafter, an example of a door weather strip for a sashless door loading vehicle according to the present invention will be described with reference to the drawings.

In the configuration shown in FIG. 1, the same components as in the prior art are denoted by the same reference numerals. That is, a retainer 2 (not shown) is attached to an opening edge of a vehicle body, and a door weather strip 20 is fitted and held in this retainer 2. This door weather) IJ Vug 20 includes a base portion 4 that fits into the retainer 2, a specific gravity inner wall portion 6 that rises from the vehicle-inward end portion of the base portion 4 along the vertical direction of the door glass 5, and the first portion 40. Mainly composed of an outer lip 9 extending obliquely downward from the outer side of the vehicle, and a main lip 8 connecting the lower end of the wall portion 6 and the tip of the outer rib 19 to form a hollow portion 7 inward. It's broken. Reference numeral 17 denotes a hollow shielding lip extending from the lower end of the wall portion 6 toward the inside of the vehicle, and the tip of the shielding lip 17 is brought into contact with a car nip sheath (8) not shown.

A small protrusion 21 metal is formed on the outer end of the outer lip 9 on the vehicle side, and fold grooves 22 and 25 are formed on the inner surface of the outer lip 9 of the hollow portion 7.

When the upper end surface 5a of this small protrusion 21μ door glass 5 rises and the main lip 8 is deformed to the position shown by the imaginary line,
It is located on the outer side of the vehicle than the upper end surface 5a of the door glass 5. A folding groove 24 is also formed on the outside of the boundary between the small protrusion 21 and the main rib 18, and a curved surface portion 25 is further formed in the middle of the main lip 8. The adhesion between the upper end surface 5a and the main lip 8 is enhanced.

According to this configuration, when the door glass 5 is raised in the direction of the arrow A when the door glass 5 is closed, the main lip 8 first
The upper end surface 5a of the door glass 5 comes into contact with the main lip 8, deforming the main lip 8. When the door glass 5 continues to rise further, as shown in the eleventh imaginary line, the upper end surface 5 &
are in contact, and at this time, the outer /19 is in the fold groove 22.23
It bends towards the inside of the car due to the action of As a result, the bending angle of the outer lip 9 becomes an acute angle, and the small protrusion 21 is shaped to be strongly pressed onto the surface of the door glass 5. Furthermore, a folded groove 24 is provided on the outside of the boundary between the small protrusion 21 and the main rib 18, and the curved surface portion 25 is formed on the upper end surface 5a of the door glass 5.
The main lip 8 is in close contact with the upper end surface 5a and is coated so as to hang over the upper end surface 5a, resulting in the following state, which has the effect of improving the airtightness between the two parts.

Effects of the Invention As has been explained in detail above, the door weather strip of the sub-shrest γ willow wheel is located at the tip of the outer lip that extends diagonally downward from the outside tip of the base, and where the upper end of the door glass comes into contact. While forming a small protrusion near the outside, on the inside of the outer rim of the hollow part and on the outside of the boundary between the small protrusion and the main lip, a crease groove is formed to enhance the flexibility of the 7. It also has the effects described below. That is, when the door glass is raised and the window is closed, the outer lip bends at an acute angle in the direction of the window glass due to the action of the fold groove, so the outer lip and the window glass form a substantially flat surface, improving the appearance. can. Furthermore, due to the improved flexibility of the outer lip and the action of the folded groove formed on the outside of the boundary between the small protrusion and the main lip, the upper end surface of the windshield and the main lip are in close contact with each other in a planar manner. It is possible to improve airtightness. In addition, when the door glass is raised, no spaces are created between the door glass and the small protrusions, so there is no risk of water retention even if high-pressure water is sprayed during car washing. I don't know. Furthermore, due to the suppressing action of the small protrusions, the main lip and the small protrusions maintain a face-sealed state so as to wrap around the upper end surface of the windshield, eliminating the habit of seal breakage.
The present invention provides a door weatherstry 11 that is useful for use in a sashless door type.
