This is because, when extrusion is performed in the assembled cross section as shown in FIG. 1, the ends of the outer seal lip 21 and the inner seal lip 31 stick to each other.

First, the portion of the outer side wall 20 will be described.
The outer side wall 20 of the glass run upper side portion 13 is formed in a substantially plate shape in cross section.
An outer cover lip 22 is formed on the outer surface side of the substantially U-shaped cross section from the front end of the outer side wall 20. Therefore, the door outer panel flange portion 2b at the end of the door outer panel 2a can be covered with the vehicle outside cover lip 22, and the appearance is good.

An outer holding groove 25 is formed between the outer side wall 20 and the outer cover lip 22. The door outer panel flange portion 2 b is inserted into and held by the vehicle outer side holding groove 25. As shown in FIG. 1, the tip of the door outer panel flange portion 2b is slightly bent in the outward direction of the vehicle to form a bending center 2k.

An outer locking lip 24 is formed on the outer surface of the outer side wall 20 corresponding to the end of the outer cover lip 22. The outer locking lip 24 extends obliquely from the outer surface of the outer side wall 20 adjacent to the bottom wall 40 of the outer outer wall 20 in the outer direction and inner circumferential direction (right inner circumferential direction in FIG. 1). It is formed as.

The outer locking lip 24 abuts on the bending center 2k of the door outer panel flange portion 2b,
The portion of the bending center 2k of the door outer panel flange portion 2b is held by the vehicle outside locking lip 24 and the vehicle outside cover lip 22. Therefore, the outer side wall 20 side of the glass run 10 is held by the door outer panel 2a.

The front end of the vehicle outside cover lip 22 is disposed in the vicinity of the front end of the vehicle outside locking lip 24, so the door outer panel flange portion 2 b inserted in the vehicle outside holding groove 25 is engaged with the vehicle outside cover lip 22 While being held by the lip 24, the door outer panel flange portion 2 b can be covered by the vehicle outside cover lip 22.

In the vehicle outer side wall 20, a vehicle outer side bent thin portion 26 is formed in the vicinity of the inner peripheral side of the continuous portion of the vehicle outer side locking lip 24 and the vehicle outer side wall 20. Therefore, as shown in FIGS. 2 and 3, in the unfolded shape before assembling the glass run 10 to the door frame 2, the tip of the outer cover lip 22 with respect to the outer lock lip 24 is engaged with the outer cover. The tip of the outside lip lip 24 is turned so that the tip of the outside lip lip 22 is covered so that the tip of the outside lip lip 24 is covered so that the tip of the outside lip 24 is covered. A step can be formed between the tip of the lip 22 and the tip.

The outboard cover lip 22 can be pivoted in a direction to widen the gap in the unfolded state with respect to the outboard locking lip 24. For this reason, the tip of the vehicle outside cover lip 22 can come out to the vehicle outside direction more than the tip of the vehicle outside locking lip 24. The solid line in FIG. 3 is a shape when the glass run 10 is deployed before being attached to the door frame 2, and the dotted line is a cross-sectional view of the glass run 10 attached to the door frame 2.

When assembling the glass run 10, as shown in FIG. 2 and FIG. 4, the tip of the door outer panel flange portion 2b is brought into contact with the outer surface of the vehicle outside locking lip 24 and the door outer panel flange portion 2b is further assembled. When the tip is slid in the tip direction along the outer surface of the vehicle outside locking lip 24, the tip of the door outer panel flange portion 2b abuts on the back side of the tip of the vehicle outside cover lip 22, and the vehicle outside cover lip The step between the tip of the outer cover lip 22 and the tip of the outer locking lip 24 without passing the outer side of the vehicle 22 between the tip of the outer locking lip 24 and the tip of the outer cover lip 22 It is possible to easily enter the vehicle outside holding groove 25 between the vehicle outside side wall 20 and the vehicle outside cover lip 22 by widening the space.

As shown in FIG. 5, the vehicle-exterior curved thin portion 26 can be formed by forming a recess 26 a in the in-vehicle side surface of the vehicle-exterior side wall 20. In this case, the bending center X of the outer side wall 20 is on the outer side of the vehicle, the distance between the bending center X and the tip of the outer cover lip 22 is shortened, and the turning locus of the tip of the outer cover lip 22 The curvature increases. Therefore, the tip of the vehicle outside cover lip 22 can be easily protruded in the outer peripheral direction than the tip of the vehicle outside locking lip 24, and the tip of the vehicle outside cover lip 22 and the vehicle outside locking lip 24 A good level difference is obtained between the front end and the front end, so that the front end of the door outer panel flange portion 2b can be easily inserted, and the assemblability of the glass run 10 is improved.

Further, the vehicle-exterior curved thin portion 26 can also be formed by forming the recess 26 b in the vehicle-exterior surface of the vehicle-exterior side wall 20. In this case, the bending center X of the outer side wall 20 is closer to the vehicle inner side, the distance between the bending center X and the tip of the outer cover lip 22 becomes longer, and the turning locus of the tip of the outer cover lip 22 is The curvature is reduced. For this reason, it is easy to secure a gap between the front end of the vehicle outside cover lip 22 and the front end of the vehicle outside engaging lip 24, and it is possible to thicken the mold of a portion corresponding to this gap, and to increase the mold strength. be able to.

If the gap between the end of the outer cover lip 22 and the end of the outer locking lip 24 is too small, it is preferable to select the setting for forming the recess 26 b on the outer surface of the outer side wall 20.
Even in this case, the front end of the vehicle outside cover lip 22 can be protruded in the outer peripheral direction than the front end of the vehicle outside engaging lip 24, and the assembling property is good.

As shown in FIGS. 2 to 4, when the glass run 10 is unfolded, the tip of the outside cover lip 22 is positioned more outward than the 24 end of the outside locking lip. Therefore, when the end of the door outer panel flange portion 2b is slid along the vehicle outside locking lip 24 when assembling the glass run 10, as described above, the end of the vehicle outside cover lip 22 and the vehicle outside locking It can pass through between the tips of the lip 24 and can easily enter the outer holding groove 25 between the outer side wall 20 and the outer cover lip 22.

An outer seal lip 21 is formed on the outer side wall 20 so as to extend toward the inner side of the substantially U-shaped cross section of the main body of the glass run 10, that is, in the direction of the bottom wall 40. Is extended from the tip of the outer side wall 20 of the vehicle.
The outer side seal lip 21 seals the outer side surface of the door glass 5.

Next, the portion of the inboard side wall 30 will be described.
Similar to the outer side wall 20, the inner side wall 30 of the glass run upper side portion 13 is formed in a substantially plate shape in cross section.
Similar to the outer cover lip 22, an inner cover lip 32 is formed on the outer side of the substantially U-shaped cross section from the tip of the inner side wall 30. For this reason, the door inner panel flange portion 2d at the tip of the door inner panel 2c can be covered with the vehicle inside cover lip 32, and the appearance is good.

An in-vehicle retaining groove 35 is formed between the in-vehicle side wall 30 and the in-vehicle cover lip 32. The door inner panel flange portion 2 d is inserted into and held by the inward holding groove 35. As shown in FIG. 1, the tip of the door inner panel flange portion 2d is slightly bent in the vehicle outer direction to form a bending center 2k.

The in-vehicle side curved thin portion 36 is formed in the vicinity of the inner peripheral side of the continuous portion between the bottom wall 40 and the in-vehicle side wall 30 in the in-vehicle side sidewall 30. Therefore, as shown in FIG. 2 and FIG. 3, at the time of deployment before assembling the glass run 10 to the door frame 2, the in-vehicle side wall 30 easily pivots relative to the bottom wall 23, and the door inner panel flange It becomes easy to insert the portion 2 d into the inward holding groove 35.

An in-vehicle retaining lip 34 is formed on the outer surface of the in-vehicle side wall 30 corresponding to the tip of the in-vehicle cover lip 32. The inward holding lip 34 and the inward cover lip 32 sandwich the portion of the bending center 2k of the door inner panel flange portion 2d. Therefore, the side wall 30 side of the glass run 10 is held by the door inner panel 2c.

Similar to the exterior side wall 20, an interior seal lip 31 is formed extending inward of the substantially U-shaped cross section of the main body of the glass run 10, that is, in the direction of the bottom wall 40.
The inner seal lip 31 is longer than the outer seal lip 21 and is thicker than the outer seal lip 21. Therefore, when the door glass 5 enters the glass run 10, the door glass 5 can be positioned on the outer side of the vehicle. Thus, the difference in level between the door frame 2 and the door glass 5 can be reduced. For this reason, air resistance and wind noise are reduced, which is preferable in design.

In the glass run upper side portion 13, when the door glass 5 ascends, the inner seal lip 31 abuts on the inner side surface of the door glass 5 and holds it, thereby sealing and holding the door frame 2 and the door glass 5 You can

In the molding of the straight part 11 of the glass run 10, a synthetic rubber and a thermoplastic elastomer are used as a molding material, and for example, in the case of a synthetic rubber, EPDM rubber, and in the thermoplastic elastomer, a polyolefin elastomer and the like Although used, it is preferable to use an olefin-based thermoplastic elastomer. In the case of using a synthetic rubber, a vulcanization step is required.

  Next, molding of the molded portion of the corner portion 12 of the glass run 10 is performed by cutting the extrusion molded member manufactured as described above into a predetermined dimension and substantially perpendicular to the longitudinal direction, and the end of the cut extruded portion The mold forming portion is held in a mold for forming the molded portion, and a material for forming the molded portion is injected into the cavity of the mold. The cross-sectional shape of the molded part is substantially the same as the cross-sectional shape of the extruded part. The molding material is preferably of the same type as the material used for the extrusion part. In the case of a thermoplastic elastomer, since the injection material is melted when injected into the mold, the heat and pressure cause the extruded portion and the molded portion to be integrally fused.

In this case, the same material is used, and the adhesion between the straight portion 11 and the corner portion 12 of the glass run 10 is good. Further, all of them are olefin-based materials, which are excellent in weather resistance, can be crushed at the same time, and can be a product that is easy to recycle. In the case of an olefin-based thermoplastic elastomer, the production is easy because no vulcanization is required.
