As shown in FIGS. 6 to 8, the window frame F ₁ is composed of an inner panel 16 and an outer panel 17, and the inner panel 16 and the outer panel 17 are formed in the window frame opening 3 in the window frame F ₁ . Are separated along the inside and outside directions of the vehicle body, and the weather strip insertion space 18 into which the main body portion 10 and the seal lip 30 of the inclined and front weather strips W ₁₁ and W ₁₂ are inserted between the panels 16 and 17. It has become. In the portion excluding the portion where the weatherstrip insertion space 18 is formed (the portion excluding the window frame opening 3), the panels 16 and 17 are in close contact with each other, and the end portions of the separated panels 16 and 17 are separated. In this structure, the weather strips W ₁₁ and W ₁₂ on the inclined portion and the front side are mounted.

A vehicle interior groove 19 is formed between the vehicle interior side wall 12 of the main body 10 and the vehicle interior shielding lip 13. An end portion 16a facing the window frame opening 3 of the inner panel 16 constituting the window frame F ₁ is inserted into the vehicle interior groove portion 19 to hold the weather strips W ₁₁ and W ₁₂ , and the inner panel 16 The vehicle inner side shielding lip 13 is elastically contacted with the inner surface of the end portion 16a to shield (seal) the portion. Similarly, a vehicle outer side groove portion 21 is formed between the vehicle outer side wall portion 14 of the main body 10 and the vehicle outer side shielding lip 15. An end portion 17a facing the window frame opening 3 of the outer panel 17 constituting the window frame F ₁ is inserted into the outer groove 21 to hold the weather strips W ₁₁ and W ₁₂ , and the outer panel 17. The vehicle outer side shielding lip 15 is elastically contacted with the outer surface of the end portion 17a to shield (seal) the portion.

Ribs 23 and 24 are formed.

Further, on the back side of the bottom wall portion 34 of the main body portion 10 of each of the inclined and front weather strips W ₁₁ and W ₁₂ , a fin-like seal lip 30 is provided in the longitudinal direction as shown in FIGS. The inner panel 16 is formed continuously, and the tip of the seal lip 30 forms a portion facing the inner surface F ₁ a of the window frame F ₁ , that is, the opening side 18 a of the weather strip insertion space 18. It abuts against the reinforcing member 22 fixed to the elastic member 22 and elastically deforms to the outside of the vehicle to seal the abutting portion. As a result, the interior of the weather strip insertion space 18 is separated into the vehicle inner side and the vehicle outer side, and air flows into the weather strip insertion space 18 from the gap between the outer panel 17 and the vehicle outer side shielding lip 15 when the vehicle is running. Even when a difference in atmospheric pressure occurs between the inside and outside of the seal lip 30, air does not flow into the vehicle interior due to the sealing action of the seal lip 30, and noise generation due to air leakage is eliminated. The portion of the inner panel 16 of the window frame F ₁ of the weatherstrip insertion space 18, may be holes such 25 for attaching the other mounting member (see FIG. 8) is opened. In this case, as shown in FIG. 3 and FIG. 8, the attachment position of the seal lip 30 along the width direction (inner side direction) of the main body portion 10 avoids the holes 25 and the window frame F _1. In order to be able to seal against the inner surface F ₁ a of the main body 10, it is displaced to the vehicle outer side along the width direction of the bottom wall portion 34 of the main body 10.

As shown in FIGS. 3 to 8, at the upper end portion (the portion having a predetermined length from the uppermost end) of the inclined portion weather strip W ₁₁ , the seal lip 30 is in the width direction on the back side of the bottom wall portion 34 of the main body portion 10. In the “other part” that is formed at the end portion on the vehicle outer side and is connected to the upper end portion of the inclined portion weather strip W ₁₁ , the seal lip 30 has a width on the back side of the bottom wall portion 34 of the main body portion 10. be formed on the end portion of the vehicle interior side in the direction, the boundary portion 30d of the upper end portion of the inclined portion weatherstrip W ₁₁ "other parts", seal lip 30, an inclined shape from the vehicle exterior toward the interior side It is formed so as to cross by gradually displacing. A weir-shaped water guiding lip 31 is formed at the upper end of the inclined portion weather strip W _{11 at} a predetermined interval on the inner side of the seal lip 30. In the embodiment, the water guiding lip 31 is formed at the upper end portion of the bottom wall portion 34 of the main body portion 10 so as to protrude from the end portion on the vehicle inner side along the longitudinal direction to a certain height, and the upper end portion. A first water guide groove V ₁ is formed between the outer rim and the seal lip 30 formed at the end of the vehicle. That is, the water guiding lip 31 intersects with the seal lip 30 at the lower end portion of the boundary portion 30d, and disappears on the downward side from the intersection. The water guiding lip 31 is formed in a portion in which the seal lip 30 of the “other portion” is linearly extended to the upper end side in the longitudinal direction of the inclined portion weather strip W _11. (Height) is shorter than the protruding length of the seal lip 30. Accordingly, the tip of the water guiding lip 31 does not come into contact with the end of the inner panel 16 that forms the bottom of the weather strip insertion space 18. The base end side of the boundary portion 30d of the seal lip 30 in the (side near the bottom wall portion 34 of the main body portion 10), the water passage holes for passing the water collected in the first water guide groove V ₁ obliquely downward 32 is formed. A portion of the inclined portion weather strip W ₁₁ excluding the upper end (portion where the first water guide groove V ₁ is formed) and the front weather strip W ₁₂ are provided on the vehicle outer side of the seal lip 30 on the second water guide groove V. ₂ are formed continuously, and the first and second water guiding grooves V ₁ and V ₂ are connected via a water passage hole 32. The second water guide groove V ₂ is a portion that guides water on the vehicle outer side than the seal lip 30, that is, a space between the seal lip 30 and the outer panel 17, but the first water guide groove V _1. Since the water that has reached the second water guide groove V ₂ through the water passage hole 32 flows along the weather strip W ₁ , the substantial part of the second water guide groove V ₂ is understood as the vehicle outer side groove portion 21.

The boundary portion 30d of the seal lip 30, while crossing diagonally along the bottom wall portion 34 of the main body portion 10 in the width direction, the first water guide groove V ₁ was in the boundary portion, is its width gradually narrows Since the taper is tapered and the seal lip 30 is not suddenly displaced, the inner surface of the window frame F ₁ (the inner surface of the inner panel 16 forming the bottom of the weather strip insertion space 18) F ₁ a is excellent. Sealability can be secured. Further, since the water passage hole 32 is formed over almost the entire longitudinal direction of the boundary portion 30d of the seal lip 30 displaced in an inclined manner, it is compared with the case where the boundary portion 30d of the seal lip 30 is displaced at a right angle. Since the area can be increased, water that has entered the weather strip W ₁ from the upper end opening 33 (see FIG. 5) at the uppermost end of the inclined portion weather strip W ₁₁ enters the water passage hole 32 from the first water guide groove V _1. The water smoothly flows into the second water guide groove V ₂ obliquely below, and is effectively discharged without accumulating in the first groove guide groove V ₁ .

The seal lip 30 is composed of a thick portion 30a on the base side and a thin portion 30b on the tip side, and the connecting portion 30c of both the portions 30a and 30b is a stepped portion with a change in thickness. Therefore, keep the rigidity at the root side of the thick portion 30a of the seal lip 30 while maintaining a predetermined shape, to better close contact with the inner surface F ₁ a of the window frame F ₁ is deflected in the tip side of the thin part 30b , Sealing performance is maintained. Further, the protruding length of the seal lip 30 changes along the longitudinal direction corresponding to the change in the distance from the bottom wall portion 34 of the main body portion 10 of the weather strip W _{1 to} the inner surface of the window frame inner surface F ₁ a. Therefore, even if the distance from the periphery of the window plate P ₁ to the window frame inner surface F ₁ a varies along the longitudinal direction (circumferential direction), a good sealing property is ensured over the entire length of the window frame inner surface F ₁ a. it can. As described above, when the distance from the peripheral edge of the window plate P ₁ to the window frame inner surface F ₁ a is changed along the longitudinal direction (circumferential direction), the change in the entire protruding length of the seal lip 30 is When the protrusion length of the thin wall portion 30b on the side is made substantially constant and the protrusion length of the thick wall portion 30a on the base side is changed, the bending allowance of the thin wall portion 30b becomes substantially constant, and the sealing property against the window frame inner surface F ₁ a Can be maintained substantially constant along the longitudinal direction, and good sealing performance can be ensured over the entire circumference of the window frame F ₁ .

Then, for example, during car washing, when high-pressure washing water is sprayed onto the window assembly A ₁ portion of the front door D ₁ from the outside of the vehicle, the upper end of the inclined portion weather strip W ₁₁ that is the uppermost portion of the window assembly A ₁ The cleaning water may enter the weather strip W ₁ from the upper end opening 33 of the head. In such a case, the water that has entered the weather strip W ₁ from the upper end opening 33 is caused by the presence of the weir-shaped water guide lip 31 as shown by the arrow Q in FIGS. After being collected in the first water guide groove V ₁ formed to be inclined between the lip 31 and the seal lip 30 on the outer side of the vehicle and flowing as it is obliquely downward, it is formed at the boundary portion 30 d of the seal lip 30. It flows while being guided downward along the second water guiding groove V ₂ outside the vehicle through the water passage hole 32 formed outside the seal lip 30. The lower end of the second water guide groove V ₂ is being opened, is discharged as it is the bottom of the vehicle body through the gap between the outer panel and the inner panel of the door frame (both not shown), i.e. to the outside of the vehicle. For this reason, water does not enter the vehicle interior.

It is also possible to attach the window assembly A _{2 according} to the present invention to the window frame opening edge of the quarter window of the rear door D ₂ in exactly the same manner. The window frame opening 4 of the quarter window of the rear door D ₂ has a substantially right triangle shape, and the window assembly A ₂ corresponding to the shape of the window frame opening 4 has a hypotenuse, and the weather strip on the hypotenuse of the upper end, it is configured like the upper end portion of the window assembly a ₁ of the inclined part weatherstrip W _11, even if the high-pressure washing water, such as in car washing infiltrates the interior of the weather strip, as it is weatherstrip It is discharged out of the vehicle below along the water guide groove. In FIG. 1, F ₂ indicates a window frame of a quarter window of the rear door D ₂ , and P ₂ indicates a window plate of the window assembly A ₂ .
