Description

  The present invention relates to a roof side weather strip for automobiles that seals between an upper portion of a door opening edge of a vehicle body and a door glass of the door.

  As a sashless door type automobile body, the door sash is eliminated, and only the door glass 5 is moved up and down freely above the belt line portion of the door 1. As a result, on the side of the automobile, only the door glass 5 can be made to appear at the upper part from the belt line portion of the door 1.

  In this case, the seal between the upper portion of the door opening edge of the vehicle body and the door glass 5 is attached to the roof side weather strip 110 attached to the upper portion of the vehicle body opening edge 6 as shown in FIG. Is performed by contacting. A retainer 4 is attached to a rail garnish 2 as a molding portion at the periphery 6 of the vehicle body opening.

  As shown in FIG. 4, the roof side weather strip 110 includes an attachment base portion 111 attached to the retainer 4 at the periphery 6 of the vehicle body opening portion, and a seal portion 150 that contacts and seals the upper end of the door glass 5. . The mounting base 111 includes a vehicle outer side wall 120, a vehicle inner side wall 130 and a bottom wall 140.

  The seal portion 150 is formed of a seal wall 151 that abuts on the upper end of the door glass 5 and a hollow portion 152. When the door glass 5 abuts, the seal wall 151 is bent into the interior of the hollow portion 152 and the upper end of the door glass 5 is It can be sealed so as to be wrapped (see, for example, Patent Document 1). A trim 170 is attached to the flange at the periphery 6 of the opening of the vehicle body, and a cover lip 159 extending from the roof side weather strip 110 abuts to cover the gap.

  However, in this case, unlike the sash door, the door glass 5 is not held by the door sash and the glass run at the upper and side outer peripheral edges, and the position of the upper end of the door glass 5 is easily shaken. At the same time, it becomes easy to bend outward. Therefore, when the door is closed, the position where the door glass 5 abuts on the seal portion 150 is changed, and the seal portion 150 is abnormally deformed, and the sealing performance may be lowered.

  Therefore, as shown in FIG. 5, the hollow seal portion is divided into two parts and sealed at two locations on the vehicle inner side surface of the upper end and the upper end of the door glass 5. On the other hand, there is one in which sealing is performed at each of the divided seal portions (see, for example, Patent Document 2).

In FIG. 5, the roof side weather strip 210 includes an attachment base portion 211 attached to the vehicle body opening peripheral edge 6, and an exterior seal portion 250 that is two seal portions formed integrally with the attachment base portion 211. And a vehicle interior seal portion 260.
The mounting base portion 211 includes a vehicle outer side wall 220, a vehicle inner side wall 230 and a bottom wall 240.

The vehicle exterior seal portion 250 and the vehicle interior seal portion 260 are formed of a sponge material.
The vehicle outer side seal portion 250 is formed on the vehicle outer side of the mounting base portion 211 and extends from the upper end and the bottom wall 240 of the vehicle outer side wall 220 to form a hollow shape. ing.

  If the vertical width of the roof side weather strip 210 is narrowed to improve the appearance, the distance between the vehicle inner side seal portion 260 and the vehicle outer side seal portion 250 may be reduced. In that case, when the door glass 5 is raised, it first comes into contact with the vehicle inner side seal portion 260 and then comes into contact with the vehicle outer side seal portion 250. In some cases, the seal portion 250 may come into contact.

In that case, the load when the door glass 5 is raised increases rapidly. Therefore, as shown in FIG. 5, there is an attempt to control the deformed shape by forming a bending point on the outer peripheral seal wall 261 of the vehicle interior seal portion 260.
However, simply forming a bending point on the seal wall 261 is insufficient for dealing with a sudden increase in load when the door glass 5 is raised.

The vehicle interior seal portion includes a vehicle interior seal portion outer peripheral wall positioned on the outer peripheral side of the roof side weather strip, a vehicle inner seal portion inner peripheral wall positioned on the inner peripheral side, a tip of the vehicle inner seal portion outer peripheral wall, and a vehicle inner seal. The front end of the inner peripheral wall is connected to the front end of the inner seal portion, and the cross-sectional shape of the outer peripheral wall of the inner seal portion is formed by curving in a convex curve in the inner peripheral direction.
The vehicle outer side surface of the vehicle inner side wall is an automobile roof side weather strip that is formed to be inclined so that the distance from the door glass becomes wider in the inner circumferential direction.

  In the first aspect of the present invention, the roof side weather strip includes a mounting base attached to the retainer at the periphery of the vehicle body opening, and a seal that is formed integrally with the mounting base and seals between the periphery of the vehicle body opening and the door glass. Part. For this reason, when the attachment base is attached to the retainer at the periphery of the vehicle body opening, the position of the seal portion is fixed, and the door glass can be reliably abutted and sealed.

  The seal portion is integrally formed on the inner peripheral side of the mounting base, and is in contact with the upper end of the door glass to seal and the outer seal portion in contact with the inner side surface of the front end portion of the door glass to seal. A hollow interior seal part is provided separately. For this reason, it can seal twice by the vehicle inner side surface of the upper end and upper end part of a door glass, and can improve a sealing performance.

Moreover, since it is formed in a hollow shape, it can flex flexibly and improve sealing performance. Furthermore, even if the door glass abuts from the side when the door is closed, or the door glass abuts from below when the door glass moves up and down, the deformation of the outer seal part and the inner seal part do not affect each other. , Each can be sealed independently, and sealability can be secured.

The attachment base is attached to the retainer and has a vehicle interior side wall formed integrally with at least the bottom wall and the vehicle interior side end of the attachment base. For this reason, when the attachment base is attached to the retainer, the bottom wall and the vehicle interior side wall can be held by the retainer, and the vehicle exterior seal portion and the vehicle interior seal portion are stably held, and the vehicle exterior seal portion and the vehicle interior side are retained. The sealing performance of the seal portion can be ensured.

  The inner seal part includes an outer wall of the inner seal part located on the outer peripheral side of the roof side weather strip, an inner peripheral wall of the inner seal part located on the inner peripheral side, the tip of the outer peripheral wall of the inner seal part, and the inner seal part A front end portion of the vehicle interior seal portion is connected to the front end of the peripheral wall. For this reason, a hollow vehicle inner side seal part deform | transforms easily, and a vehicle inner side seal part front-end | tip part can contact | abut and seal on a door glass.

The cross-sectional shape of the outer peripheral wall of the vehicle inner seal portion is formed to be curved in a curved shape convex in the inner peripheral direction. For this reason, when the front end of the door glass comes into contact with the inner seal portion, the portion formed by curving in the inner peripheral direction is not local but can be deflected as a whole. The rotation trajectory of the front end portion of the inner seal portion can be made small, and when the front end of the door glass comes into contact, the front end portion of the vehicle inner seal portion can be made difficult to come into contact with the outer seal portion. Moreover, rainwater can be discharged out of the vehicle from the curved portion of the outer peripheral wall of the vehicle inner seal portion, and rainwater can be prevented from entering the vehicle.

The vehicle outer side surface of the vehicle inner side wall is formed so as to be inclined so that the distance from the door glass becomes wider in the inner circumferential direction. For this reason, even if the vertical width of the roof side weather strip is reduced, the distance between the front seal portion of the vehicle inner side and the seal portion of the outer side of the vehicle can be increased. In addition, it is possible to make it difficult for the front end portion of the vehicle inner seal portion to come into contact with the vehicle outer seal portion.

  According to the second aspect of the present invention, the most concave portion of the inner circumferential surface formed by curving the outer peripheral wall of the vehicle inner seal portion is more inner than the most distal portion of the front end portion of the vehicle inner seal portion. 1 is a roof side weather strip for an automobile located in a direction.

According to the second aspect of the present invention, the most concave portion of the inner peripheral surface formed by curving the outer peripheral wall of the vehicle inner seal portion is more inner than the most distal portion of the front end portion of the vehicle inner seal portion. Located in the direction. For this reason, the outer peripheral wall of the vehicle inner seal portion is easily bent, and when bent, the vehicle inner seal portion distal end portion is bent so as to be pulled toward the root side. When the front end of the door glass comes into contact, it is possible to make it difficult for the front end portion of the vehicle inner side seal portion to come into contact with the outer side seal portion.

  According to a third aspect of the present invention, there is provided a roof side weather strip for automobiles in which the outer peripheral wall of the vehicle inner seal portion has a substantially constant thickness.

In the present invention of claim 3, since the thickness of the outer peripheral wall of the vehicle inner seal portion is substantially constant, the easiness of bending of the outer peripheral wall of the vehicle inner seal portion is uniform, and the front end of the door glass is in the vehicle inner seal portion. When abutting, the outer peripheral wall of the vehicle inner seal portion bends uniformly as a whole, and does not bend locally. It is possible to make it difficult for the front end portion of the vehicle inner seal portion to come into contact with the portion.

  According to a fourth aspect of the present invention, there is provided a roof side weather strip for an automobile in which an outer peripheral surface of the front end portion of the inner side seal portion is formed to bulge in the outer peripheral direction.

In the present invention of claim 4, since the outer peripheral surface of the front end portion of the vehicle inner seal portion is formed to bulge in the outer peripheral direction, the rigidity of the front end portion of the inner seal portion is increased, and the front end of the door glass is sealed to the inner side seal. When it comes into contact with the portion, the front end portion of the vehicle inner seal portion is difficult to bend, and the front end portion of the vehicle inner seal portion is reliably brought into contact with the inner side surface of the door glass, so that the seal surface pressure can be improved. In addition, because the rigidity of the front end part of the vehicle inner seal part is high, the contact area when contacting the inner side surface of the door glass is small, and it is not pulled up by the door glass rising, and it interferes with the vehicle outer seal part. Can be prevented.

  According to the fifth aspect of the present invention, the vehicle interior side wall has a vehicle interior side wall interior column portion, the vehicle exterior side has a vehicle interior side wall first vehicle exterior column portion, and the inner periphery side is a vehicle interior side wall.

It is a roof side weather strip.

In the present invention of claim 5, the vehicle interior side wall has a vehicle interior side wall interior column portion, the vehicle exterior side has a vehicle interior side wall first vehicle exterior column portion, and the inner periphery side is a vehicle interior side wall. A second vehicle outer side column portion is provided, and the outer peripheral side has a vehicle inner side wall root portion. For this reason, the vehicle interior side wall has the vehicle interior side wall and the vehicle interior side column portion attached to the retainer, and the vehicle interior side has the vehicle interior side wall and the vehicle interior side wall first vehicle exterior side column portion and vehicle interior side wall second vehicle exterior side. The inner seal portion can be held by the column portion.

The vehicle interior side wall includes a vehicle interior side wall, a vehicle interior side wall, a first vehicle exterior column, a vehicle interior side wall, a second vehicle exterior column, and a vehicle interior side wall hollow portion surrounded by a vehicle interior side wall root. For this reason, the weight of the vehicle inner side wall can be reduced, and when the door glass rises, the vehicle inner side wall first vehicle outer side column portion is prevented from being bent excessively, thereby deforming the vehicle inner side seal portion. Stable shape deformation and seal reaction force can be obtained.

The vehicle interior side wall first vehicle exterior column portion and the vehicle interior side wall second vehicle exterior column portion are connected at an angle of 145 to 160 degrees. For this reason, when the door glass rises, the hollow shape is maintained, and the connecting portion between the first inner side column portion on the inner side wall and the second outer column portion on the inner side wall is bent inside the hollow portion on the inner side wall. The sealing performance can be ensured by suppressing the occurrence of the problem and stably expressing the seal reaction force due to the deformation of the vehicle interior seal portion.

When the connection angle between the vehicle inner side wall first vehicle outer column and the vehicle inner side wall second vehicle outer column is less than 145 degrees, the vehicle inner side wall second vehicle outer column and the vehicle inner side wall When the connecting portion is located away from the inner peripheral wall of the vehicle inner seal portion, the resistance to the force pulling the inner peripheral wall of the vehicle inner seal portion in the vehicle outer direction generated by the rise of the door glass is reduced, and the vehicle inner side wall cover lip is raised. May be a bug. When the connection angle exceeds 160 degrees, the reaction force against the vehicle inner side surface of the door glass of the vehicle inner side seal portion is deformed by the deformation of the vehicle inner side wall first vehicle outer column portion and the vehicle inner side wall second vehicle outer column portion. It will decline.

  According to the sixth aspect of the present invention, the vehicle outer side surface of the vehicle inner side wall is the vehicle outer side surface of the first vehicle outer side column portion of the vehicle inner side wall, and is inclined so that the distance from the door glass becomes wider toward the inner circumferential direction. This is a roof side weather strip for automobiles formed as described above.

In the present invention of claim 6, the vehicle outer side surface of the vehicle inner side wall is the vehicle outer side surface of the first vehicle outer side column portion of the vehicle inner side wall, and is inclined so that the distance from the door glass becomes wider toward the inner circumferential direction. Is formed. For this reason, even if the space between the first vehicle outer side column portion on the vehicle inner side wall and the outer seal portion on the vehicle side becomes large and the vehicle inner side wall first vehicle outer column portion is not bent when the door glass is raised, It is possible to secure a space in which the distal end portion of the seal portion can rotate.

The angle formed by the vehicle interior side wall first vehicle exterior pillar portion and the door glass rising direction is preferably 5 to 20 degrees, and more preferably 7 to 15 degrees. When the angle is less than 5 degrees, the distance between the first vehicle outer side column portion on the vehicle inner side wall and the vehicle inner side surface of the door glass becomes small, so abnormal deformation (buckling deformation) of the curved portion on the outer peripheral wall of the vehicle inner seal portion ) Occurs, the reaction force decreases and the sealing performance decreases. When the angle exceeds 20 degrees, the reaction force of the entire vehicle interior seal portion is reduced and the sealing performance is deteriorated. Moreover, when the reaction force of the vehicle inner seal portion is reduced, the pressing force of the door glass in the vehicle outer direction is reduced, which may lead to the door glass fluttering.

  According to the seventh aspect of the present invention, the base portion of the outer peripheral wall of the vehicle inner side seal portion is connected to the connection portion of the first vehicle outer side column portion of the vehicle inner side wall and the second vehicle outer side column portion of the vehicle inner side wall, and the inner peripheral wall of the vehicle inner seal portion. The base portion of the vehicle is connected to the tip portion of the inner side wall of the vehicle inner side wall, and the portion where the inner peripheral wall of the inner side seal portion is connected to the inner side of the vehicle rather than the portion where the root portion of the outer peripheral wall of the inner side seal portion is connected. It is a roof side weather strip.

In the present invention of claim 7, the root portion of the outer peripheral wall of the vehicle inner side seal portion is connected to the connection portion of the first vehicle outer side column portion of the vehicle inner side wall and the second vehicle outer side column portion of the vehicle inner side wall, and the inner peripheral wall of the vehicle inner seal portion. The base part of the vehicle interior side wall is connected to the front end part of the vehicle inner side pillar part, and the part where the vehicle inner seal part inner peripheral wall is connected is located on the vehicle inner side than the part where the root part of the vehicle inner seal part outer peripheral wall is connected. Yes. For this reason, the vehicle inner seal portion inner peripheral wall can be formed longer than the vehicle inner seal portion outer peripheral wall, and when the door glass rises and the vehicle inner seal portion outer peripheral wall is deformed, the vehicle inner seal portion inner peripheral wall becomes the vehicle inner seal portion. Following the deformation of the outer peripheral wall, the sealing performance can be ensured.

  According to the eighth aspect of the present invention, there is provided an automobile roof side wall in which the vehicle inner side wall and the vehicle inner side wall base portion are formed of a solid material, and the vehicle inner side seal portion and the vehicle outer side seal portion are formed of a sponge material. The strip.

More preferably, it is 7 to 15 degrees.
When the angle is less than 5 degrees, the distance between the vehicle inner side wall first vehicle outer side column portion 36 and the vehicle inner side surface of the door glass 5 is reduced, and therefore the vehicle inner seal portion outer peripheral wall curved portion 61a is deformed abnormally ( When buckling deformation occurs, the reaction force decreases and the sealing performance decreases. When the angle exceeds 20 degrees, the reaction force of the entire vehicle interior seal portion 60 is reduced and the sealing performance is deteriorated. Further, when the reaction force of the vehicle inner side seal portion 60 is reduced, the pressing force of the door glass 5 toward the outside of the vehicle is reduced, which may lead to the door glass 5 fluttering.

  The seal portion of the roof side weather strip 10 is integrally formed on the inner peripheral side of the mounting base portion 20, and has a hollow exterior seal portion 50 that contacts and seals the upper end of the door glass 5, and the front end of the door glass 5. A hollow interior seal portion 60 that seals against the interior side surface of the vehicle is provided separately.

For this reason, it can seal double by the vehicle inner side surface of the upper end and upper end part of the door glass 5, and can improve a sealing performance. Moreover, since it is formed in a hollow shape, it can flex flexibly and improve sealing performance. Further, even if the door glass 5 abuts from the lateral direction when the door is closed, or the door glass 5 abuts from below when the door glass 5 moves up and down, the deformation of the vehicle outer seal portion 50 and the vehicle inner seal portion 60 affect each other. Therefore, each can be sealed independently, and sealing performance can be secured.

The vehicle exterior seal portion 50 is formed of a sponge material in a hollow shape, and is connected to the vehicle exterior seal portion vehicle exterior holding wall 51 continuous with the tip of the vehicle exterior side wall 21 and the vehicle exterior side continuous from the bottom wall connecting portion 42 of the bottom wall 40. It is formed from a seal portion abutting wall 52 and has a vehicle exterior seal portion hollow portion 54.

The front end of the vehicle outer side seal portion vehicle outer side holding wall 51 and the vehicle outer side seal portion abutting wall 52 are connected to each other, and a vehicle outer side seal portion concave portion 53 is formed at the connecting portion. When the front end of the door glass 5 comes into contact, it can bend at the portion of the vehicle exterior seal portion recess 53.
A rail garnish front end portion 2 a of the rail garnish 2 is in contact with the outer surface of the vehicle outer side seal portion vehicle outer side holding wall 51. The contact portion of the vehicle outer side seal portion vehicle outer side holding wall 51 is formed thick.

  The vehicle interior seal portion 60 is formed of a sponge material in a hollow shape, and the vehicle interior seal portion outer peripheral wall 61 located on the outer peripheral side of the roof side weather strip 10, that is, the bottom wall 40 side, and the inner peripheral side, that is, the vehicle inner side wall. 30, a vehicle inner seal portion inner peripheral wall 62, a vehicle inner seal portion outer peripheral wall 61 and a vehicle inner seal portion inner peripheral wall 62 connected to each other. A portion 64 is provided. For this reason, the hollow vehicle inner side seal part 60 can be easily deformed, and the vehicle inner side seal part front end part 63 can contact and seal the side surface of the door glass 5 on the vehicle inner side.

The vehicle inner seal portion outer peripheral wall 61 is formed to be curved in a curved shape in the inner peripheral direction, that is, the vehicle outer seal portion hollow portion 64, and has a vehicle inner seal portion outer peripheral wall curved portion 61a near the center. ing. One end of the vehicle inner side seal portion outer peripheral wall 61 is connected to the connecting portion of the vehicle inner side wall first vehicle outer side column portion 36 and the vehicle inner side wall second vehicle outer side column portion 37, and the other tip is as described above. It is connected to the vehicle interior seal portion front end portion 63.

When the front end of the door glass 5 comes into contact with the vehicle inner seal portion 60, the vehicle inner seal portion outer peripheral wall curved portion 61a has a locally curved portion convexly curved in the inner peripheral direction. However, when the front end of the door glass 5 comes into contact with the outer side seal portion 50, the outer side seal of the outer side seal portion 50 can be bent. It is possible to make it difficult for the vehicle inner side seal portion tip portion 63 to come into contact with the portion contact wall 52.

It is preferable that the most concave portion of the inner peripheral surface of the vehicle inner seal portion outer peripheral wall curved portion 61a is located in the inner peripheral direction with respect to the most distal portion of the vehicle inner seal portion distal end portion 63. In this case, the vehicle interior seal portion outer peripheral wall 61 is easily bent, and when bent, the vehicle interior seal portion distal end portion 63 is bent so as to be pulled toward the root side. Can be made small, and when the front end of the door glass 5 abuts, it is possible to make it difficult for the vehicle inner side seal portion front end portion 63 to come into contact with the vehicle outer side seal portion abutment wall 52 of the vehicle outer side seal portion 50. .
Moreover, the vehicle inner side seal portion outer peripheral wall curved portion 61a serves as a bag, and can discharge rain water to the outside of the vehicle in the front-rear direction of the vehicle, thereby preventing rain water from entering the vehicle.

The vehicle inner seal portion outer peripheral wall 61 preferably has a substantially constant thickness. In this case, the easiness of bending of the vehicle inner seal portion outer peripheral wall 61 is uniform, and when the door glass 5 is raised, the front end of the door glass 5 comes into contact with the vehicle inner seal portion inner peripheral wall 62 of the vehicle inner seal portion 60. In some cases, the outer seal wall 61 of the vehicle inner seal portion is uniformly bent as a whole, so that the rotation locus of the front end portion 63 of the vehicle inner seal portion can be reduced, and the vehicle outer seal portion contact wall of the vehicle outer seal portion 50 can be reduced. It is possible to make it difficult for the vehicle inner side seal portion distal end portion 63 to come into contact with 52.

The outer peripheral direction of the vehicle inner seal front end portion 63, that is, the vehicle inner seal front end portion outer peripheral surface 63a, which is the surface on the bottom wall 40 side, is preferably formed to bulge in the outer peripheral direction. In this case, the rigidity of the front end portion 63 of the vehicle inner side seal portion is increased, and when the front end of the door glass 5 comes into contact with the inner side seal portion 60, the front end portion 63 of the vehicle inner side seal portion is difficult to bend. The vehicle inner side seal portion distal end portion 63 reliably contacts the vehicle inner side surface, and the seal surface pressure can be improved. Moreover, since the rigidity of the front end portion 63 of the vehicle inner seal portion is high, the contact area when contacting the vehicle inner surface of the door glass 5 is small, and the vehicle outer seal portion 50 is not pulled up by the rise of the door glass 5. Can be prevented.

One end of the vehicle interior seal portion inner peripheral wall 62 is connected to the vehicle interior side wall distal end portion 32 at the distal end of the vehicle interior side wall vehicle interior column portion 31, and the other distal end is, as described above, the vehicle interior seal portion distal end portion 63. It is connected to the.
In the vehicle inner seal portion inner peripheral wall 62, the portion where the root portion of the vehicle inner seal portion inner peripheral wall 62 is connected is located on the vehicle inner side than the portion where the root portion of the vehicle inner seal portion outer peripheral wall 61 is connected.

For this reason, the vehicle inner seal portion inner peripheral wall 62 can be formed longer than the vehicle inner seal portion outer peripheral wall 61, and when the door glass 5 rises and the vehicle inner seal portion outer peripheral wall 61 is deformed, the vehicle inner seal portion inner peripheral wall 62. Can follow the deformation of the outer peripheral wall 61 of the vehicle inner seal portion to ensure the sealing performance.

Next, a state in which the door glass 5 is in contact with the roof side weather strip 10 will be described with reference to FIG.
When the door glass 5 rises, the upper end of the door glass 5 first comes into contact with the vehicle inner side seal portion distal end portion 63 of the vehicle inner side seal portion 60. At that time, the vehicle inner seal portion outer peripheral wall 61 of the vehicle inner seal portion 60 is bent by the vehicle inner seal portion outer peripheral wall curved portion 61a, and the vehicle inner seal portion distal end portion 63 is the vehicle outer seal portion of the vehicle outer seal portion 50. It rotates without contacting the contact wall 52.

Thereafter, the upper end of the door glass 5 further rises and comes into contact with the vehicle outer side seal portion abutting wall 52 of the vehicle outer side seal portion 50, so that the vehicle outer side seal portion concave portion 53 bends and the vehicle outer side seal portion abutting wall 52. Is bent so as to wrap the upper end of the door glass 5 inside the hollow portion 54 of the vehicle outer side seal portion. When the door glass 5 ascends, the vehicle interior seal portion distal end portion 63 with which the front end of the door glass 5 first comes into contact with the vehicle interior seal portion outer peripheral wall curved portion 61a is bent. Is smaller and does not come into contact with the vehicle outer side seal portion contact wall 53, so that the rising load of the door glass 5 does not increase when the door glass 5 is raised.
Further, since the vehicle interior side wall first vehicle exterior column portion vehicle exterior surface 36 a is formed to be inclined, the vehicle interior seal portion distal end portion 63 is formed away from the vehicle exterior seal portion abutment wall 52.

Since the vehicle exterior seal portion 50 is hollow and formed of a sponge material, it can be flexibly deformed. For this reason, the seal | sticker between the upper end of the door glass 5 and the vehicle outer side seal part 50 is securable. Moreover, since the vehicle outer side seal portion vehicle outer side holding wall 51 is held by the rail garnish tip 2a, the upper end of the door glass 5 can be held so as not to be displaced to the vehicle outer side.

  When the door glass 5 rises, the vehicle inner side seal part front-end | tip part 63 of the vehicle inner side seal | sticker part 60 contact | abuts to the vehicle inner side surface of the upper end part of the door glass 5. FIG. As the door glass 5 rises, the vehicle inner side seal portion distal end portion 63 slides between the vehicle inner side surface of the door glass 5 and bends upward, and between the vehicle inner side surface of the door glass 5 and the vehicle inner seal portion 60. Seal.

Since the portion of the outer peripheral surface 63a of the front end portion of the vehicle inner seal portion is formed thick, the rigidity of the front end portion 63 of the vehicle inner seal portion is increased, and the front end of the door glass 5 is in contact with the inner seal portion 60. In some cases, the vehicle interior seal portion distal end portion 63 is unlikely to be bent, and the vehicle interior seal portion distal end portion 63 is reliably brought into contact with the vehicle interior side surface of the door glass 5 to improve the seal surface pressure. Moreover, since the rigidity of the front end portion 63 of the vehicle inner seal portion is high, the contact area when contacting the vehicle inner surface of the door glass 5 is small, and the vehicle outer seal portion 50 is not pulled up by the rise of the door glass 5. Can be prevented.

  For this reason, it can seal double by the vehicle inner side surface of the upper end and upper end part of the door glass 5, and can improve a sealing performance. Further, since the vehicle exterior seal portion 50 and the vehicle interior seal portion 60 are formed separately, the vehicle exterior seal portion 50 and the vehicle interior seal portion 60 are not closed when the door is closed and when the door glass 5 is raised or lowered. The deformations do not affect each other and can be sealed independently, and the sealing performance can be ensured.

  The vehicle interior seal portion 60 can be bent by the vehicle interior seal portion outer peripheral wall curved portion 61a so that the cross section is further bent and deformed into an L shape when the vehicle contacts the vehicle interior side surface of the door glass 5 when the door is closed. It has become. For this reason, when the door glass 5 abuts, the vehicle interior seal portion 60 is flexibly deformed and the vehicle interior seal portion 60 reliably abuts the door glass 5 even if the position of the door glass 5 is shifted. Can be sealed.

  In addition, since the vehicle interior seal portion 60 is hollow rather than lip-shaped, the door glass 5 is more rigid than the lip-shaped when the door glass 5 is raised and lowered, so that it is not caught and abnormally deformed. Furthermore, since it is bent at the predetermined bent portion as described above when it comes into contact with the door glass 5, the overall change amount of the vehicle interior seal portion 60 is small, and the sealing performance is not deteriorated.

The roof side weather strip 10 is made of synthetic rubber, thermoplastic elastomer, or soft synthetic resin for both solid material and sponge material. For example, EPDM rubber is used for synthetic rubber, olefinic elastomer is used for thermoplastic elastomer, and soft synthetic resin is used. As the resin, soft vinyl chloride or the like is used.
In the case of synthetic rubber, it is conveyed to a vulcanizing tank after extrusion and heated by hot air or high frequency to vulcanize. In the case of a thermoplastic elastomer or a soft synthetic resin, it is cooled and solidified. Thereafter, it is cut to a predetermined length, and the production of the extruded part is completed.
