DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the weather strip of the present invention is shown in FIG.
~ It demonstrates according to FIG.

In the figure, an arrow FR indicates a vehicle width front side direction, an arrow IN indicates a vehicle width inner side direction, and an arrow UP indicates a vehicle upward direction.

As shown in FIG. 3, the weather strip 10 of the present embodiment is a door glass inner weather strip provided at a sliding portion of the front side door 12 with the door glass 14.

As shown in FIG. 2, a weather strip 1
Reference numeral 0 has a lip portion 18 that is in sliding contact with the door glass 14. A lower lateral wall 20 extends from the lower end of the lip portion 18 toward the inside in the vehicle width direction. Above the lower lateral wall 20, a molding portion as an upper lateral wall is formed substantially parallel to the lower lateral wall 20. 22 is formed. The lower lateral wall 20 and the molding portion 22 are connected by a connecting portion 24, and form a trim holding portion 26 having a U-shaped cross section with the opening facing inward in the vehicle width direction.

As shown in FIG. 1, a claw 20A is formed at the tip of the lower lateral wall 20 toward the outer side in the upward diagonal vehicle width direction. The claw 20A is formed on the rear surface 30A of the door trim 30.
It is adapted to engage with a step portion 32 formed in the vicinity of the edge portion. The claw 20A also acts as a guide when the door trim 30 is inserted. Further, the front end of the molding 22 is curved downward, and the front end surface 22A of the molding 22 has the door trim 30.
And the door trim 30 is pressed against the lower lateral wall portion 20 side.

As shown in FIG. 2, an outer standing wall 34 extending downward from the lip portion 18 is formed at an outer end of the lower lateral wall 20 in the vehicle width direction. An inner wall 36 is formed downward in an intermediate portion in the longitudinal direction of the lower lateral wall 20, and the outer wall 34, the inner wall 36, and a part of the lower lateral wall 20 have a U-shaped cross section with the opening portion facing downward. The panel holding portion 38 having the shape of a circle is formed.

As shown in FIG. 1, the lower end portion 34A of the outer standing wall 34 is bent obliquely downward and outward in the vehicle width direction, and the lower end portion 36A of the inner standing wall 36 facing the lower end portion 34A is inward in the vehicle width direction. It is bent diagonally downward. Therefore, when the door inner panel 40 is inserted into the panel holding portion 38, these lower end portions 34A and 36A act as guides.

On the surface of the outer standing wall 34 facing the inner standing wall 36, projections 42 having an arcuate cross section are formed at a predetermined interval in the vertical direction. The inner wall 36 includes the protrusion 4 of the outer wall 34.
A lip 44 is formed at a portion facing 2 to hold the door inner panel 40 between the lip 44 and the protrusion 42.

As shown in FIG. 2, the inner wall 36 is inclined downward toward the outside of the vehicle, and the distances D1 and D2 between the lip 44 and the protrusion 42 are narrower toward the bottom (D1 < D2). Further, the base portion of the lower lateral wall 20 is a low rigidity portion 40. That is, at the base of the lower lateral wall 20, the cutout portion 43 is formed from below, and the wall thickness T1 of the low-rigidity portion 40 is thin. Therefore, the lower horizontal wall 2
0 can be swung in the clockwise rotation direction of FIG. 2 (direction of arrow A in FIG. 2) and the counterclockwise rotation direction of FIG. 2 (direction of arrow B in FIG. 2) with the low-rigidity portion 40 as the center of rotation.

The intersection of the lower horizontal column 20 and the inner column 36 is a high rigidity portion 45. That is, the buildup portion 46 is formed on the inner side in the vehicle width direction of the intersection of the lower horizontal column 20 and the inner column 36, and the wall thickness T2 of this portion is increased.

Next, the operation of this embodiment will be described. In the weather strip 10 of the present embodiment, the base portion of the lower lateral wall 20 on which the inner wall 36, which forms a part of the trim holding portion 26 and a part of the panel holding portion 38, is erected,
The low-rigidity portion 40 is formed by the hollow portion 43.

For this reason, when the door trim 30 is inserted into the trim holding portion 26, the lower lateral wall 20 has the low rigidity portion 40.
2 is swung in the direction of arrow A in FIG. 2, the assembly load is reduced, and the assembly workability is improved.

Next, the weather strip 10 assembled to the door trim 30 is assembled to the door inner panel 40. At this time, when the door inner panel 40 is inserted into the panel holding portion 38, the gap between the lip 44 and the protrusion 42 is widened, so that the inner wall 36 receives a force in the direction of the arrow B and the inner wall 3 receives the force.
6 and the lower lateral wall 20 integrally swing about the low-rigidity portion 40 in the direction of sandwiching the door trim 30. Further, the claw 20A swings integrally with the lower lateral wall 20 by the high rigidity portion 45. Therefore, the trim holding force (arrow F1 in FIG. 1) is improved.

At the same time, a reaction force for returning the claw 20A in the direction of arrow A acts on the lower lateral wall 20, and the panel holding force of the inner wall 36 (arrow F2 in FIG. 1) is improved by this reaction force. And the panel holding force and the trim holding force are balanced.

Therefore, the assembling workability is good, and the holding force of the door inner panel 40 and the door trim 30 can be improved.

Further, in the weather strip 10 of this embodiment, the force of inserting the door trim 30 into the trim holding portion 26 can be reduced, so that the claw 20A can be made harder than before, and the assembly of the door trim 30 can be achieved. The feeling of moderation when attached is improved.

In the above, the present invention has been described in detail with reference to specific embodiments, but the present invention is not limited to such embodiments, and various other embodiments are possible within the scope of the present invention. It is obvious to a person skilled in the art that
For example, as shown in FIG. 4, the cutouts 43 and 45 may be formed from the upper and lower sides at the base of the lower lateral wall 20. Further, the low-rigidity portion 40 may be configured by small holes, slits or the like instead of the cutout portions 43, 45. The high-rigidity portion 45 may be formed by inserting a hard resin or the like instead of the built-up portion 46. Further, although the present embodiment has been described with respect to the door glass inner weather strip, it can be applied to other weather strips.

[0028]

According to the present invention, the lip portion which is in sliding contact with the door glass, the door trim holding portion composed of a pair of upper and lower lateral walls, the inner wall which is erected at a substantially right angle to the lower lateral wall of the pair of lateral walls, and which faces the inner wall. A weather strip having a door inner panel holding part formed of an outer wall and a low-rigidity part formed at a base of the lower horizontal wall and a high rigidity formed at an intersection of the lower horizontal wall and the inner wall.
