Although not shown, the molded lower lip portion 53E is elastically contacted with the vehicle interior side surface of the rising surface 12a of the press sash 12 when the door weatherstrip 50 is attached.

Further, as shown in FIGS. 3 to 6, a highly foamed sponge material 90 having a specific gravity of 0.05 to 0.4 is provided on the inner side of the position where the second bead portion 80 is connected.
2 to 5, the highly foamed sponge material 90 is provided so as to extend from the lower portion of the mounting base portion 51A of the upper extruded portion 51 to the lower portion of the mounting base portion 53A of the molded portion 53. The upper surface of the bottom surface portion 11b3 of the guide rail portion 11b and the upper surface of the mounting surface 12b of the press sash 12 are elastically contacted.
Further, as shown in FIG. 2, the highly foamed sponge material 90 is provided so as to gradually move toward the outer side of the vehicle as it descends from the molded portion 53 toward the lower extruded portion 52 side.

According to the door weatherstrip 50 configured in this manner, the door weatherstrip 50 is positioned above the vehicle exterior projecting portion 11b1 of the guide rail portion 11b of the roll sash 11 so as to straddle the joint step portion Z of the roll sash 11 and the press sash 12. The rear lip portion 53D is brought into elastic contact with the vehicle interior side surface of the upper end edge portion 11a, and the first bead portion 70 is brought into elastic contact with the vehicle exterior concave rising surface 11b4 of the guide rail portion 11b. It is possible to prevent the water W from entering from the outside to the inside of the vehicle through the double seal portion (the back lip portion 53D and the first bead portion 70).
The dotted line L2 in FIG. 1 shows the seal line formed by the elastic contact of the rear lip portion 53D at this time, and the dotted line L3 in FIG. 1 shows the seal line formed by the first bead portion .

At this time, the water W from the joining stepped portion Z is caused to descend along the vehicle outer side of the rear lip portion 53D and the first bead portion 70, so that this also prevents the water W from entering the vehicle inner side. .

In addition, the rear lip portions 51D and 53D extend continuously from a position spaced upward from the vehicle-exterior protrusion 51A1 formed on the mounting base portion 51A of the upper extruded portion 51 toward the molding portion 53 without a break. In addition, the first bead portion 70 also extends seamlessly from the vehicle exterior side surface of the vehicle exterior protrusion 53A1 of the mounting base 53A of the molded portion 53 connected to the mounting base 51A of the upper extruded portion 51 so as to straddle the joint stepped portion Z. Since it extends continuously, the water W does not enter the inside of the vehicle through the cut.

In addition, it extends from the lower surface of the vehicle-exterior projection 53A1 of the mounting base 53A of the molding portion 53, which is connected to the vehicle-exterior projection 51A1 formed on the mounting base 51A of the upper extruded portion 51, toward the junction stepped portion Z side. Further, the second bead portion 80 is provided which is in elastic contact with the bottom surface portion 11b3 of the guide rail portion 11b of the roll sash 11, straddles the joint step portion Z, and is in elastic contact with the upper surface of the mounting surface 12b of the press sash 12. 1. Even if the water W is launched into the inside of the vehicle beyond the first bead portion 70, the water W is blocked by the second bead portion 80, so that the water stopping function and the drainage function are further excellent.
The seal line by the second bead portion 80 at this time is indicated by a dotted line L4 in FIG.

Further, as shown in FIG. 2, the rear lip portion 53D is lowered above the first bead portion 70 with the rear horizontal extension portion 53D1 extending linearly from the upper extruded portion 51 at the upper portion of the molding portion 53. Since the water is branched into the rear surface descending extension portion 53D2 that extends downward, the amount of water applied to the rear surface lip portion 53D can be dispersed in two directions. Alternatively, the rear lip 53D may be connected to the molded lower lip 53E and connected to the rear lip 52D formed on the lower extruded portion 52 without branching.

In addition, since the first bead portion 70 is gradually brought closer to the outside of the vehicle as it descends in the molding portion 53, the water that has entered the first bead portion 70 can be led further to the outside of the vehicle. In particular, by moving the clip hole 40 to the outside of the vehicle, it is possible to effectively prevent the water W from entering the inside of the vehicle from the clip hole 40.例文帳に追加
At that time, as shown in FIG. 2, the first bead portion 70 approaches the rear surface descending extension portion 53D2. The water W guided by cannot be drained. Therefore, it is preferable that the descending portion Q of the rear surface descending extension portion 53D2 disappear before the first bead portion 70 so as not to approach the first bead portion 70 too much. However, when both are close to each other as shown in FIG. 14, which is an enlarged cross-section taken along line KK of FIG. For example, the height of the connecting portion S is preferably set to a height that does not elastically contact the rising surface 12a of the press sash 12, so that the drainage function can be maintained.

In addition, since the high-foam sponge material 90 is provided on the inner side of the vehicle from the connecting position of the second bead portion 80, even if the water is launched into the inner side of the vehicle beyond the second bead portion 80, the high-foam sponge material Since the water W is dammed up by the sponge material 90, the water stopping function and the drainage function are further improved.
Further, since the highly foamed sponge material 90 is gradually brought closer to the outside of the vehicle as it descends from the molded part 53 toward the lower extruded part 52, the water W that has entered the highly foamed sponge material 90 is more likely to be removed from the outside of the vehicle. can lead to

In this embodiment, the provision of the first bead portion 70, the second bead portion 80, and the highly foamed sponge material 90 enhances the effect of preventing the water W from entering from the joint stepped portion Z. Even if the second bead portion 80 is omitted or the highly foamed sponge material 90 is also omitted, a high water stoppage and drainage function can be obtained.

In this embodiment, the rear door 2 has been described as an example, but the door roof sash provided on the roof side of the front door 1 is welded to the roll sash at the corner portion of the front upper edge of the press sash. It can also be applied to other types to which the molded part of the door weatherstrip is attached.
