Description

  The present invention relates to a seal structure for an automobile door, and more particularly to a seal structure for an automobile door that improves the sound insulation of noise entering the vehicle interior from outside the vehicle through the door.

  In general, a glass run is provided along the inner periphery of a door frame of an automobile door. A glass weather strip is provided along the belt line of the door. The glass run is composed of an extruded part formed into a long shape and a mold part that connects the extruded parts at a predetermined angle. For example, the glass run is arranged along the shape of the door frame. It consists of a vertical side, an upper side, and a rear vertical side. Further, the glass run has a U-shaped main body portion as viewed from the cross-sectional direction, and also includes an inside seal lip and an outside seal lip extending inside the body portion. Sealing is performed so that the outer peripheral edge is sandwiched.

  The glass weather strip includes an inner weather strip attached to the upper edge of the door inner panel and an outer weather strip attached to the upper edge of the door outer panel. Both weather strips are provided with seal lips extending from the respective bases so as to sandwich the door glass from the inner and outer surfaces.

  Now, the glass weather strip is attached with its end abutted against the vertical side of the glass run. By the way, when the glass run and the glass weather strip are configured separately and assembled to the door, a gap may be formed at the abutting portion between the glass inner weather strip and the glass run. In this case, noise may enter the vehicle interior from the gap, which may cause in-vehicle noise.

  In order to prevent the above problems, there is a technique of integrally forming a glass inner weather strip and a glass run. By adopting such a configuration, there is no gap in the abutting portion between the glass inner weather strip and the glass run, so that the sound insulation can be reliably improved. However, in this case, there is a risk that the assembly workability is lowered and the mold structure is complicated.

On the other hand, for the part of the glass run that collides with the end of the glass inner weather strip, the mounting portion attached to the door inner panel and the inner side surface of the door glass are sealed in the same manner as the glass inner weather strip. There is a technique of projecting and forming a convex portion provided with a sealing lip (see, for example, Patent Document 1).
JP 2004-90735 A

  By adopting the configuration of Patent Document 1, the gap between the glass inner weather strip and the glass run can be eliminated, and the glass inner weather strip and the glass run are configured separately. Therefore, a decrease in assembly workability can be avoided. However, in the technique described in Patent Document 1, it is necessary to form a convex portion having the same configuration as that of the glass inner weather strip. There is a risk of increasing costs.

  Also, since the sealing direction is different between the glass run car interior seal lip and the seal lip extending from the base attached to the door inner panel, the sealing performance is hindered at the site where both are continuous. There is a risk that abnormal noise may be generated when the door glass is raised and lowered. Further, such a problem occurs in the same manner even when the glass inner weather strip and the glass run are integrally formed.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent intrusion of noise into the vehicle interior, and to prevent an increase in cost and generation of abnormal noise when the door glass is raised and lowered. An object of the present invention is to provide an automotive door seal structure.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A body portion attached to a mounting portion provided along the inner periphery of the door frame of the automobile door, and having a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion, and having a substantially U-shaped cross section; A vehicle outer seal lip that extends from a substantially leading end of the vehicle outer side wall portion toward the inside of the main body portion and seals an outer surface of the door glass, and a pair with the vehicle outer seal lip, and forms an inner surface of the door glass. A glass run having a car interior seal lip to seal;
A glass inner weather strip having a base attached to a door inner panel along a belt line of an automobile door, and a seal lip extending from the base and sealing an inner surface of the door glass;
Regarding at least one of the longitudinal sides before and after the glass run,
In the abutting portion facing the end of the glass inner weather strip, a connecting portion is provided for connecting a substantially leading end portion of the vehicle interior side wall portion and an end portion of the door frame of the vehicle interior seal lip. ,
The boundary portion between the connecting portion and the vehicle interior seal lip at the abutting portion is formed at the front end portion of the vehicle interior side wall portion and the base of the vehicle interior seal lip that does not face the end of the glass inner weather strip. While being positioned closer to the inner periphery of the door frame than the end,
The root portion of the vehicle interior seal lip at the abutting portion is positioned closer to the door glass than the root portion of the vehicle interior seal lip at the general portion,
A sealing structure for an automobile door, wherein an end of the glass inner weather strip is brought into contact with the connecting portion.

  According to the means 1, the boundary portion between the connecting portion and the vehicle inner side seal lip at the glass run contact portion is located on the door frame more than the front end portion of the vehicle inner side wall portion and the base end portion of the vehicle inner side seal lip. Located on the inner circumference. That is, the glass run bulges toward the inner peripheral side of the door frame at the abutting portion. For this reason, a glass run and the terminal of a glass inner weather strip can be made to contact reliably, and the clearance gap between the glass inner weather strip and a glass run can be eliminated. As a result, the sound insulation can be improved.

  Further, the root portion (base end portion) of the vehicle interior seal lip at the abutting portion is located closer to the door glass than the root portion (base end portion) of the vehicle interior seal lip at the general portion. That is, the glass run also bulges to the door glass side at the meeting part. For this reason, the clearance gap between the vehicle inside seal lip of a glass run and the door glass inner surface can be reduced, and the improvement of sound insulation can be aimed at.

  In addition, the shape of the glass run is only to bulge the contact part to the inner peripheral side of the door frame and the door glass side, so the mold structure for molding the glass run (competition part) is complicated. As a result, an increase in cost can be prevented. In addition, with regard to the glass inner weather strip, it is only necessary to cut at least the ends that are struck against the glass run, so that the manufacturing workability can be improved.

  Furthermore, since the glass run and the glass inner weather strip are configured separately, it is possible to prevent the assembly workability from being deteriorated due to the configuration of the two. In addition, since the seal lip provided at the base attached to the door inner panel and the vehicle interior seal lip provided at the vertical side of the glass run are configured separately, the seal lips are continuously integrated. As compared with the case where it is formed, it is possible to improve the sealing property, and it is possible to prevent the possibility that abnormal noise is generated when the door glass is raised and lowered. Further, unlike the case where a convex portion or the like is provided on the vehicle interior seal lip, it is not necessary to make the vehicle interior seal lip thick, so that the reaction force (force to push the door glass) of the vehicle interior seal lip increases. Such a risk can be prevented. As a result, when the door glass is raised and lowered, it is possible to more reliably prevent the possibility that abnormal noise is generated.

  Mean 2. The connecting portion has a predetermined length by separating a base portion of the vehicle interior seal lip and the vehicle interior side wall portion, and a state in which the body portion of the glass run is attached to the mounting portion of the automobile door And in a state where the base portion of the glass inner weather strip is not attached to the door inner panel, from the substantially front end portion of the vehicle interior side wall portion to the inner side surface of the door glass, or The vehicle seal structure according to claim 1, wherein the vehicle seal structure extends in an inclined manner toward the inner peripheral side of the door frame.

  According to the means 2, the contact area between the glass run and the glass inner weather strip can be increased, and the effect of reducing the gap between the inner seal lip of the glass run and the inner surface of the door glass can be reliably achieved. Therefore, the sound insulation is improved.

  Further, when the connecting portion extends from the substantially tip end portion of the vehicle inner side wall portion to the inner peripheral side of the door frame, the end of the glass inner weather strip is more than the boundary portion between the connecting portion and the vehicle inner side wall portion. The tip portion or the intermediate portion is first contacted, and the connecting portion follows and bends at the time of the contact. For this reason, when the glass inner weather strip is brought into contact with the glass inner weather strip, it is possible to suppress the possibility that the inner side wall portion is stretched and the assembly workability is deteriorated.

  Even if the connecting portion extends substantially from the front end portion of the vehicle inner side wall portion so as to be substantially orthogonal to the inner side surface of the door glass, the end of the glass inner weather strip is connected to the boundary between the connecting portion and the vehicle inner side wall portion. When configured so as not to come into contact with the part, the same effect is obtained. Of course, the same effect can be obtained when the connecting portion is curved (bent) so as to slightly swell from the vehicle interior side wall toward the inner peripheral side of the door frame.

  Means 3. The automobile sealing structure according to means 1 or 2, wherein the connecting portion is thinner than the vehicle inner side wall portion.

  According to the means 3, flexibility is increased at the connecting portion, and for example, cutting variations in the longitudinal direction of the glass inner weather strip can be absorbed. Further, even when the door glass vibrates toward the inside of the vehicle, an increase in the reaction force of the vehicle inside seal lip can be suppressed.

  Means 4. Means 1 to characterized in that the inclination angle and the tip position of the tip portion of the vehicle interior seal lip at the abutting portion are substantially the same as the inclination angle and tip position of the vehicle interior seal lip at the general portion. 4. The automobile seal structure according to any one of 3 above.

  According to the means 4, in the longitudinal direction of the glass run, the sliding contact portion of the vehicle interior seal lip with the door glass can be aligned, and the sliding movement of the door glass is caused by the fact that the sliding contact portion is not constant. At this time, it is possible to avoid the problem that the door glass rattles.

  Hereinafter, an embodiment will be described with reference to the drawings. FIG. 1 is a schematic front view showing a schematic configuration of a door. 2 is a cross-sectional view taken along the line JJ of FIG. 1 showing the configuration of the glass run, and FIG. 3 is a cross-sectional view taken along the line KK of FIG. 4 is a cross-sectional view taken along line LL in FIG. 1 showing the configuration of the glass inner weather strip.

  As shown in FIG. 1, the vehicle door 51 (front door in the figure) guides the raising and lowering of the door glass DG, and the outer periphery of the door glass DG and the door frame 52 when the door glass DG is raised and closed. A glass run 1 is provided for sealing between the two. More specifically, the channel portion DC formed along the inner periphery of the door frame 52 and the inner periphery of the sash DS provided in the door panel 53 so as to extend the front and rear vertical portions of the door frame 52 downward.

As shown in the figure, the extruded portion 4 constituting the rear vertical side portion includes a main body portion 11, a vehicle outer side seal lip 12, and a vehicle inner side seal lip 13. The main body 11 includes a base portion 14 fitted into the channel portion DC, a vehicle outer side wall portion 15 and a vehicle inner side wall portion 16 extending from the base portion 14, and has a substantially U-shaped cross section as a whole. The vehicle outer side seal lip 12 extends from a substantially leading end of the vehicle outer side wall portion 15 toward the base portion 14 side. Further, in the present embodiment, the sub lip 17 extending from the front end portion of the vehicle outer side wall portion 15 toward the front end portion side of the vehicle inner side wall portion 16 is provided on the inner peripheral side of the door frame 52 relative to the vehicle outer side seal lip 12. ing.

  The vehicle interior seal lip 13 extends from the distal end portion of the connecting portion 18 extending from the substantially distal end of the vehicle interior side wall portion 16 toward the vehicle exterior side wall portion 15 side toward the base portion 14 side. When the door glass DG is closed, the vehicle outer side seal lip 12 is pressed against the outer side surface of the door glass DG, and the vehicle inner side seal lip 13 is pressed against the inner side surface of the door glass DG. Thereby, the vehicle exterior side and vehicle interior side of the door glass DG are each sealed. In addition, in the present embodiment, a design lip 19 for inserting (hiding) the front end portion of the garnish 55 is provided so as to protrude from the connecting portion 18.

  The vehicle outer side wall portion 15 is formed to be relatively shorter than the vehicle inner side wall portion 16, and the vehicle outer side seal lip 12 is also set to be relatively smaller (shorter) than the vehicle inner side seal lip 13. Has been. Thereby, the vehicle exterior side surface of the channel portion DC can be set small, the appearance is improved, and the door glass DG is brought close to the vehicle exterior so that the flash surface is realized. Further, the extrusion molding parts 2 and 3 and the mold molding parts 5 and 6 also include a main body part 11 and a pair of seal lips 12 and 13. In addition, the main body 11 and the seal lips 12 and 13 in this embodiment are made of EPDM (ethylene-propylene-diene copolymer rubber).

  Further, as shown in FIG. 3, in the present embodiment, the design lip 19 and the sub lip 17 are omitted for the portion of the glass run 1 that is disposed in the door panel 53 below the belt line and does not appear in appearance. The size is reduced with the sash DS to which such a part is attached. In this embodiment, after the extrusion molding portion 4 is extruded, the design lip 19 and the sub lip 17 in the portion of the extrusion molding portion 4 disposed in the door panel 53 are cut to obtain the shape as described above. Yes.

  As shown in FIG. 1, a glass weather strip 20 is attached along the door belt line. As shown in FIG. 4, the glass weather strip 20 includes a glass inner weather strip 21 attached to the upper edge of the door inner panel 57 and a glass outer weather strip 41 attached to the upper edge of a door outer panel (not shown). Become.

  The glass inner weather strip 21 is located on a door trim side (not shown) which is an interior product, and extends upward and obliquely upward from the base portion 22 and comes into contact with the inner side surface of the door glass DG and a lower seal lip 24. have. The base portion 22 is made of a hard olefin-based thermoplastic elastomer (TPO) and is fitted to the upper edge of the door inner panel 57. Both seal lips 23 and 24 are made of soft TPO, and the presence of the seal lips 23 and 24 seals between the door inner panel 57 and the door glass G. Both end portions (terminals) of the glass inner weather strip 21 are abutted against the extruded portions 3 and 4, respectively. Incidentally, flocking (not shown) is applied to the sliding surfaces of the seal lips 23, 24 with the door glass DG.

  Now, as shown in FIG. 5, in the present embodiment, a portion (abutting portion) facing the rear end of the glass inner weather strip 21 in the extrusion molding portion 4 constituting the rear vertical side portion of the glass run 1. It is formed by molding. More specifically, in such an abutting portion, the portion on the tip side from the intermediate position of the vehicle interior side wall portion 16, the connecting portion 18, and the vehicle interior seal lip 13 are configured by a mold forming portion 31 made of EPDM. As described above, at the abutting portion of the extrusion molding portion 4, the tip end side of the vehicle interior side wall portion 16, the connecting portion 18, and the vehicle interior seal lip 13 are configured by the mold molding portion 31. For convenience, the names (numbers) of these members will be used as they are.

  6 is a cross-sectional view taken along line VV in FIG. As shown in the figure, the upper part of the mold part 31 has a shape that matches the shape of the general part (see FIG. 2) above the belt line in the extrusion part 4. In the longitudinal direction, no step is formed at the boundary between the upper edge of the mold part 31 and the extrusion part 4.

  FIG. 8 is a cross-sectional view taken along the line XX of FIG. As shown in the figure, the lower part of the molding part 31 has a shape that matches the shape of the general part (see FIG. 3) below the belt line in the extrusion part 4. In the longitudinal direction, no step is formed at the boundary between the lower edge of the mold part 31 and the extrusion part 4. That is, the design lip 19 is omitted.

  FIG. 7 is a cross-sectional view taken along the line WW in FIG. As shown in the figure, at the intermediate portion of the mold forming portion 31, the vehicle interior side wall portion 16 is extended to the inner peripheral side of the door frame 52 (door 51), and the base end portion of the vehicle interior seal lip 13 ( The root portion), that is, the boundary portion α between the connecting portion 18 and the vehicle interior seal lip 13 is located at the front end portion of the vehicle interior side wall portion 16 and the vehicle interior seal lip 13 at a general portion located above or below the mold forming portion 31. It is located in the inner peripheral side of the door frame 52 and the inner surface side of the door glass DG from the base end portion (root portion). In the present embodiment, in the front-rear direction of the door 51, the position of the front end portion of the vehicle interior side wall portion 16 at the intermediate portion of the mold forming portion 31 is substantially the same as the position of the front end portion of the design lip 19 in the general part above the mold forming portion 31. It is the same position. Further, the connecting portion 18 in the intermediate portion extends in a direction substantially orthogonal to the inner side surface of the door glass DG when the main body portion 11 is attached to the channel portion DC.

  As shown in FIG. 5, the end of the lower seal lip 24 of the glass inner weather strip 21 is abutted against (contacts) the connecting portion 18 at the intermediate portion of the mold forming portion 31. In the present embodiment, the end of the lower seal lip 24 of the glass inner weather strip 21 is cut straight (perpendicular to the extending direction of the glass inner weather strip 21), whereas the upper stage. The end of the seal lip 23 is cut obliquely. And the terminal of the said upper stage seal lip 23 is the structure collided from the design lip 19 of the mold forming part 31 upper part to the vehicle interior seal lip 13 of the general site | part above the mold forming part 31. FIG. It should be noted that the end of the base portion 22 of the glass inner weather strip 21 may also be abutted against the connecting portion 18 at the intermediate portion of the molded portion 31.

  In addition, since the connection part 18 in the intermediate part of the mold forming part 31 is configured to be thinner than the vehicle inner side wall part 16 and the vehicle inner seal lip 13, the connection part 18 is brought into contact with the end of the lower seal lip 24. However, it is deformed in a follow-up manner so as to tilt toward the base portion 14 with the boundary with the vehicle interior side wall portion 16 as the center. In the present embodiment, the thickness of the inner seal lip is 1.5 mm at the intermediate portion of the mold forming portion 31, whereas the thickness of the connecting portion 18 is 1.2 mm.

  Further, as described above, the inner side seal lip 13 of the middle portion of the mold forming portion 31 has a base end portion inside the door frame 52 that is more than the inner side seal lip 13 of the general portion above or below the mold forming portion 31. Although it is located on the peripheral side and on the door glass DG side, the inclination angle and the tip end position on the tip end side are the same as the seal lip 13 of the general part. In other words, at the intermediate portion of the mold forming portion 31, the extension angle of the vehicle interior seal lip 13 is slightly closer to the vehicle interior side wall portion 16, and the vehicle interior seal lip 13 is attached to the vehicle interior seal lip 13 at the intermediate portion. The outer side wall portion 15 is bent. Thereby, in the longitudinal direction of the extrusion molding part 4, the sliding contact site | part with the door glass DG of the vehicle interior seal lip 13 is arrange | equalized.

  As described in detail above, in the present embodiment, the mold forming part 31 is formed at the abutting portion of the extruded part 4, and the boundary between the connecting part 18 and the vehicle interior seal lip 13 in the middle part of the mold forming part 31. The portion α is located on the inner peripheral side of the door frame 52 with respect to the distal end portion of the vehicle interior side wall portion 16 and the base end portion of the vehicle interior seal lip 13 which are located above and below the mold forming portion 31. That is, the extruded portion 4 bulges toward the inner peripheral side of the door frame 52 at the abutting portion. For this reason, the extrusion molding part 4 and the terminal of the glass inner weather strip 21 can be made to contact reliably, and the clearance gap between the glass inner weather strip 21 and the glass run 1 can be eliminated. As a result, the sound insulation can be improved.

  Further, the boundary portion α (the root portion of the vehicle inner side seal lip 13) between the connecting portion 18 and the vehicle inner side seal lip 13 in the intermediate portion of the molded portion 31 is formed between the connecting portion 18 of the general part and the vehicle inner side seal lip 13. It is located closer to the door glass DG than the boundary portion α (the root portion of the vehicle interior seal lip 13). That is, the extrusion molding part 4 also bulges to the door glass DG side at the abutting part. For this reason, the clearance gap between the vehicle inner side seal lip 13 and the door glass DG inner surface in the intermediate part of the shaping | molding part 31 of the extrusion molding part 4 can be reduced, and the improvement of sound insulation can be aimed at.

  Moreover, as the shape of the glass run 1 (extrusion molding part 4), the extrusion part 4 (die molding part 31) is only bulged on the inner peripheral side of the door frame 52 and the door glass DG side. ) Can be prevented from becoming complicated, and an increase in cost can be prevented. In addition, with respect to the glass inner weather strip 21 as well, since at least the terminal that is abutted against the extruded portion 4 is cut straight, the manufacturing workability can be improved.

  Furthermore, the glass run 1 (extrusion molding part 4) and the glass inner weather strip 21 are comprised separately, thereby preventing the assembly workability from being lowered due to the integral construction of the two. be able to. Further, since the seal lips 23, 24 provided on the base portion 22 attached to the door inner panel 57 and the vehicle interior seal lip 13 provided on the extrusion molding portion 4 are configured separately, both the seal lips 23 are provided. , 24, and 13 can be made better than the case where they are continuously formed integrally, and the possibility of abnormal noise being generated when the door glass DG is raised and lowered can be prevented. Can do. Further, unlike the case where a convex portion or the like is provided on the vehicle interior seal lip 13, it is not necessary to make the vehicle interior seal lip 13 thick, so the reaction force of the vehicle interior seal lip 13 (force to push the door glass DG) is increased. The fear of becoming large can be prevented. As a result, when the door glass DG is raised and lowered, it is possible to more reliably prevent a possibility that abnormal noise is generated.

  In addition, since the connecting portion 18 is thinner than the inside seal lip 13 and the inside wall side wall portion 16, the glass inner portion of the connecting portion 18 is brought into contact with the connecting portion 18 and the glass inner weather strip 21. The cutting variation of the weather strip 21 can be absorbed.

  Further, since the glass inner weather strip 21 is abutted at the connecting portion 18 extending substantially orthogonally to the inner side surface of the door glass DG from the substantially front end portion of the vehicle interior side wall portion 16 toward the inside of the main body portion 11, extrusion molding is performed. The contact area between the portion 4 and the glass inner weather strip 21 can be increased, and the sound insulation is improved. Furthermore, since the connecting portion 18 is deformed in a follow-up manner, the glass run 1 and the glass inner weather strip 21 are set so as to be surely contacted even if variations due to manufacturing errors or assembly errors occur. Can do.

  In addition, the inclination angle and the tip portion position of the front end portion of the vehicle interior seal lip 13 are substantially the same as the inclination angle and the front end portion position of the vehicle inner seal lip 13 in the general portion also in the middle portion of the mold forming portion 31. . For this reason, in the longitudinal direction of the extrusion molding part 4, the sliding contact site | part with the door glass DG of the vehicle interior seal lip 13 can be arrange | equalized, and it originates in this sliding contact site | part being non-constant. It is possible to avoid the problem that the door glass DG rattles when ascending and descending.

  Further, in the present embodiment, the glass inner weather strip 21 is not only struck against the intermediate portion of the mold forming portion 31 of the extruded portion 4 at the end of the lower seal lip 24 but also at the end of the upper seal lip 23. Since the upper part of the molding part 31 and the general part above the molding part 31 are struck together, the sound insulation is further improved. Further, the end of the lower seal lip 24 is cut straight, whereas the end of the upper seal lip 23 is cut obliquely. For this reason, the contact portion of the upper seal lip 23 and the contact portion of the lower seal lip 24 with respect to the extruded portion 4 are shifted in the front-rear direction of the vehicle. As a result, the passage route of the sound (noise) trying to pass from the lower part of the lower seal lip 24 to the upper part of the upper seal lip 23 is not linear, and as a result, the intrusion of the sound into the vehicle interior is more reliably suppressed. be able to.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the said embodiment, although the contact part of the extrusion molding part 4 which opposes the rear terminal of the glass inner weather strip 21 is comprised by the mold-forming part 31, it replaces with or adds to this structure, The abutting portion of the extrusion molding portion 3 facing the front end of the glass inner weather strip 21 may be constituted by the mold molding portion 31, and the abutting portion may be bulged toward the inner peripheral side of the door frame 52.

  Further, in the above embodiment, only a part of the contact portions of the extrusion molding portion 4 (the tip portion of the vehicle inner side wall portion 16, the connecting portion 18, and the vehicle inner seal lip 13) is constituted by the mold forming portion 31. However, the entire abutting portion (the main body 11 and the seal lips 12 and 13) may be formed by a mold forming portion. In this case, if the cross-sectional shape is different between the part above the belt line and the part below the belt line in the extrusion molding part 4, the mold can be connected after extrusion molding, thereby improving workability. The quality is improved.

  (B) Moreover, the connection part 18 is good also as extending inclining from the substantially front-end | tip part of the vehicle interior side wall part 16 to the inner peripheral side of the door frame 52. As shown in FIG. By adopting such a configuration, for example, in the state of collision, even when the inner surface of the base portion 22 of the glass inner weather strip 21 is located on the inner side of the vehicle inner side wall portion 16, The end of the glass inner weather strip 21 comes into contact with the front end portion or the intermediate portion of the connecting portion 18 before the boundary portion α with the vehicle inner side wall portion 16, and the connecting portion 18 follows and bends during the contact. It will be. For this reason, when the glass inner weather strip 21 is brought into contact with the glass inner weather strip 21, it is possible to suppress the possibility that the vehicle interior side wall portion 16 is stretched and the assembly workability is deteriorated.

  Further, the connecting portion 18 may be curved (bent) so as to slightly swell from the vehicle inner side wall portion 16 toward the inner peripheral side of the door frame 52. Also in this case, the same effect can be obtained.

  (C) In the above-described embodiment, the main body 11, the seal lips 12, 13, and the molded part 31 are made of EPDM, but may be made of another material such as TPO. Further, in the above-described embodiment, the extrusion molding portion 4 of the front door is described in detail. However, the molding portion 31 may be similarly provided in the extrusion molding portion (for example, the front vertical side portion) of the rear door. .
