Description

  The present invention relates to a glass run channel that is mounted along a window frame of an automobile, guides a window glass that moves up and down, and seals between the window glass and the window frame, and a window frame structure equipped with the glass run channel. It is.

  In general, the window frame structure of an automobile is mounted with a long glass run channel along the inner periphery of the door window frame, for example, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2002-301936). The glass run channel guides the sliding movement (up-and-down movement) of the window glass. As shown in FIG. 9, a conventional glass run channel 1 includes a base portion 3 that faces the end surface of a window glass 2, and a vehicle formed from both ends in the width direction of the base portion 3 toward the window glass 2 side. Inner and outer side wall portions 4a and 4b, and inner and outer side seal lips 5a and 5b formed from the front end sides of the side wall portions 4a and 4b toward the center in the width direction of the base portion 3, respectively. Each of the side walls 4a, 4b is provided with shielding lips 6a, 6b on the inside and outside of the vehicle that are formed from the front end side toward the opposite side of the sealing lips 5a, 5b. And the inner peripheral edge of the window frame 7 is covered with the shielding lips 6a and 6b.

The glass run channel 1 has the upper end of the window glass 2 at the base when the window glass 2 is raised to the highest lifted position (fully closed position) in order to ensure hermeticity when the window glass 2 is fully closed. The part 3 is set to be pushed up from the position indicated by the dotted line in FIG. 9 to the position indicated by the solid line.
JP 2002-301936 A (second page, etc.)

  In the conventional glass run channel 1, the positional relationship between the base portion 3 and the most elevated position of the window glass 2 is shifted due to variations in assembly, particularly in a portion where a stopper is not attached to the panel door described later. 2 may be increased when the base 3 is pushed up at the upper end of the window glass 2 when the window 2 is fully closed. For this reason, even if a clearance is provided between the root portion of the shielding lip 6b outside the vehicle and the lower end of the inner peripheral edge of the window frame 7 as shown by the dotted line in FIG. The push-up amount of the part 3 may be larger than the clearance. In this state, as shown by a solid line in FIG. 9, when the window glass 2 is fully closed, the base portion of the shielding lip 6b outside the vehicle lifted integrally with the base 3 by pushing up the window glass 2 is the window. When the upper limit of the inner peripheral edge of the frame 7 is strongly pressed and the limit is exceeded, the shielding lip 6b is further displaced so as to be pulled into the groove of the window frame 7, and as a result, the shielding lip 6b on the outside of the vehicle. There may be a case where “open mouth deformation” occurs in which the tip end portion of the door is deformed away from the window frame 7. When the mouth opening deformation occurs, an unpleasant wind noise is generated by the shielding lip 6b deformed during traveling, or rainwater enters between the opening shielding lip 6b and the window frame 7 in the rain. In some cases, this rainwater could enter the inside of the car.

The present invention has been made in consideration of such circumstances. Therefore, the object of the present invention is to prevent the opening of the shielding lip when the window glass is fully closed, and to prevent the window glass from being fully closed. It is to allow improvement in the sealing property and realize the prevention of the occurrence of wind noise.

In order to achieve the above object, a glass run channel according to claim 1 of the present invention is made of an elastic polymer material that is mounted along a window frame of an automobile to guide sliding movement of the window glass. A long glass run channel that is opposed to the end face of the window glass when it is mounted on a window frame, and an inner side wall and an outer side wall extending so as to rise from both ends in the width direction of the base part. And the vehicle interior side and the vehicle exterior side that protrude toward the center in the width direction of the base part from the front end side of the vehicle interior side and the vehicle side side wall part and can contact the window glass when mounted on the window frame. The seal lip is formed in a folded shape so as to form a concave groove between the side wall portion on the vehicle exterior side and the vehicle exterior side wall side from at least the vehicle exterior side wall portion, and is attached to the window frame. When window frame A shielding lip that covers the inner peripheral edge and whose bottom shape of the groove substantially matches the inner peripheral edge of the window frame, and an easily deformable part located between the base part and the side wall part on the vehicle outer side, The easily deformable portion has a substantially flat plate shape that is thinner than the thickness of the base portion and the side wall portion on the outside of the vehicle, and the easily deformable portion is in the state in which the glass run channel is attached to the window frame. When the end surface of the window glass presses the base portion toward the outer peripheral side of the window frame, the bottom surface of the groove is formed on the inner peripheral edge of the window frame. The easily deformable portion is elastically deformed with a force that is weaker than the force that causes opening deformation of the shielding lip so that the easily deformable portion rotates upward with the side wall portion on the outside of the vehicle as a fulcrum. It is set as the structure which deform | transforms.

In this configuration, even if the positional relationship between the base and the window glass shifts due to assembly variations, and the amount of displacement of the base due to the pressing of the window glass when the window glass is fully closed increases, Accordingly, the easily deformable portion can be easily elastically deformed and the displacement of the base portion can be absorbed by the elastic deformation of the easily deformable portion, and the displacement of the base portion of the shielding lip can be reduced. Thus, when the window glass is fully closed, the shielding lip can be prevented from being displaced so as to be pulled into the groove of the window frame, and the opening of the shielding lip when the window glass is fully closed can be prevented. In addition, the sealing performance between the shielding lip and the window frame when the window glass is fully closed can be improved, and the generation of wind noise during traveling can be prevented.

  Specifically, as in the second aspect, the easily deformable portion is arranged in a direction intersecting with the forward direction of the window glass between the base portion side of the side wall portion and the base portion where the end face of the window glass contacts. It is good to form so that a bending part may be provided. In this way, even if the displacement of the base due to the pressing of the window glass when the window glass is fully closed becomes large, the gap between the base side of the side wall and the base part where the end face of the window glass abuts. Since the easily deformable portion provided in the bent portion is bent and deformed, the displacement of the base portion of the shielding lip can be reduced, and the opening deformation of the shielding lip when the window glass is fully closed can be prevented.

Alternatively, as in claim 3, the base portion may be formed in a hollow shape, and a glass contact portion that is easily deformable may be integrally formed in a portion of the base portion that contacts the end face of the window glass. good. In this way, if the base portion is formed into a hollow shape, the displacement of the base portion due to the pressing of the window glass when the window glass is fully closed is caused by the portion of the base portion that comes into contact with the end face of the window glass (the glass plate that is easily deformed). and can be generated in the contact portion), it is possible to reduce the displacement of the base portion of the shielding lip.

  According to a fourth aspect of the present invention, at least a part of the easily deformable portion may be integrally formed of a polymer material that is more flexible and easier to extend than the side wall portion. If it does in this way, the easily deformable part which deform | transforms easily easily can be formed, and the opening deformation prevention effect of a shielding lip can be heightened.

  Further, as described in claim 5, it is preferable to use rubber or thermoplastic elastomer as the elastic polymer material for forming the glass run channel. In this way, a long glass run channel can be easily produced by extrusion molding of rubber or a thermoplastic elastomer, and the appropriate elasticity required for the glass run channel can be provided.

  In addition, as described in claim 6, the inner peripheral edge of the window frame is fitted into the bottom surface of the concave groove formed between the side wall portion and the shielding lip so that the bottom surface of the concave groove is relative to the inner peripheral edge of the window frame. In addition, a fitting groove that prevents sliding movement in the width direction may be formed. In this way, even if the root portion of the shielding lip is about to be displaced toward the outer peripheral side of the window frame, the shielding lip is formed by fitting the inner peripheral edge of the window frame with the fitting groove of the concave groove. It can prevent being pulled into the groove of the window frame, and the effect of preventing the opening deformation of the shielding lip can be further enhanced.

  In general, a glass run channel consists of an upper glass run channel mounted along the top of the window frame, a side glass run channel mounted along the side of the window frame, an upper glass run channel and a side glass run. Since it is composed of a corner glass run channel that joins the channels, all of the upper glass run channel, the side glass run channel, and the corner glass run channel may be provided with an easily deformable portion. As shown in FIG. 7, at least the upper glass run channel may be provided with an easily deformable portion. The reason for this is that the glass run channel that is pressed most strongly by the window glass that is raised to the highest position when the window glass is fully closed is the upper glass run channel. This is because it is most likely to occur.

  Moreover, if the glass run channel according to any one of claims 1 to 7 is attached to a window frame of a vehicle body to form a window frame structure as in claim 8, the effects of claims 1 to 6 described above can be obtained. The window frame structure which has is realizable.

  By the way, if a stopper that restricts the displacement of the base portion of the glass run channel is provided on the entire portion of the window frame that faces the base portion of the glass run channel, the opening of the shielding lip can be prevented from being deformed. For panel doors in which the outer door panel and inner door panel are overlapped by hemming, the window frame is integrally formed with the door, so the stopper that regulates the displacement of the base of the glass run channel must be a separate part from the window frame. In general, stoppers are attached only to the minimum necessary locations. For this reason, the glass run channel attached to the window frame of the panel door has many portions where the stopper is not arranged, and in many of these portions, the effect of the stopper is not exerted, and the displacement amount of the base portion becomes large and the shielding lip is increased. May be deformed.

  Therefore, the present invention is particularly effective when applied to a glass run channel attached to a window frame provided in a panel door as in the ninth aspect. As described above, the glass run channel attached to the window frame of the panel door has a large amount of displacement of the base part and may cause the shielding lip to open and deform in many parts. If the opening of the shielding lip is prevented from being deformed, the effect of applying the present invention is great.

  Hereinafter, three embodiments 1 to 3 in which the present invention is applied to a glass run channel mounted on a window frame of an automobile panel door will be described.

  A first embodiment of the present invention will be described with reference to FIGS. First, a schematic configuration of the panel door 11 will be described with reference to FIG. The panel door 11 is formed by stacking and pressing a press-molded outer door panel and inner door panel by hemming or the like. A window frame 12 is formed integrally with the panel door 11, and a long glass run channel assembly 13 made of an elastic polymer material is attached to the window frame 12 along the window frame 12. The sliding movement (lifting movement) of the window glass 14 is guided by the solid 13.

  The glass run channel assembly 13 includes an upper glass run channel 15 mounted along the upper part (the roof corresponding part and the front pillar corresponding part) of the window frame 12, and a front side part mounted along the front side part of the window frame 12. The glass run channel 16, the rear glass run channel 17 mounted along the rear side (center pillar corresponding part) of the window frame 12, the upper glass run channel 15 and the front glass run channel 16 are joined. It comprises a front corner glass run channel 18 and a rear corner glass run channel 19 that joins the upper glass run channel 15 and the rear glass run channel 17 together.

  As the elastic polymer material for molding the glass run channel assembly 13, for example, rubber mainly composed of EPDM, thermoplastic elastomer such as TPO, or resin material such as polyolefin is used, and the upper glass run channel 15 and the front side glass run channel are used. 16 and the rear side glass run channel 17 are each formed in a straight line during molding by extrusion molding or the like. Further, the front corner glass run channel 18 and the rear corner glass run channel 19 are each formed in a curved shape according to the shape of the corner portion of the window frame 12 by injection molding or the like.

  In this case, the elastic polymer material is injected into the cavity of the injection mold with the front end portion of the upper glass run channel 15 and the upper end portion of the front side glass run channel 16 set in the injection mold of the front corner glass run channel 18. By forming the front corner glass run channel 18, the upper glass run channel 15 and the front side glass run channel 16 are joined via the front corner glass run channel 18. On the other hand, in the state where the rear end portion of the upper glass run channel 15 and the upper end portion of the rear side glass run channel 17 are set in the injection mold of the rear corner glass run channel 19, an elastic polymer material is provided in the cavity of the injection mold. To form the rear corner glass run channel 19, the upper glass run channel 15 and the rear glass run channel 17 are joined via the rear corner glass run channel 19.

  Next, the structure of the upper glass run channel 15 will be described with reference to FIGS. The upper glass run channel 15 includes a base portion 21 facing the upper end surface of the window glass 14, a vehicle inner side wall portion 22 and a vehicle outer side wall portion 23 extending so as to rise from both end sides in the width direction of the base portion 21. The vehicle interior side seal lip 24 and the vehicle exterior side seal lip 25 projecting from the front end side of each side wall portion 22, 23 toward the center in the width direction of the base portion 21, and the front end side of each side wall portion 22, 23. A shielding lip 28 on the vehicle interior and a shielding lip 29 on the vehicle exterior formed in a folded shape so as to form the concave grooves 26 and 27 in the spaces surrounded by the side walls 22 and 23 are integrally formed. . Further, at least the shielding lip 29 on the vehicle outer side is formed so that the shape of the bottom surface of the concave groove 27 substantially coincides with the inner peripheral edge 31 of the window frame 12.

  When the upper glass run channel 15 is mounted on the window frame 12, the inner rim 30 on the inner side 30 and the inner rim 31 on the outer side of the car frame 12, respectively, Is supposed to cover up. Further, in order to ensure the sealing property when the window glass 14 is fully closed, when the window glass 14 is raised to the vicinity of the most elevated position (fully closed position), the seal lip 24 on the vehicle interior and the seal lip on the vehicle exterior side. 25 is in contact with the glass surface on the vehicle interior side and the glass surface on the vehicle exterior side of the window glass 14 and the base portion 21 is in contact with the upper end surface of the window glass 14 so that the window glass 14 rises to the highest position. The upper end surface of the glass 14 is set so as to push up the base 21 slightly. In addition, when the upper glass run channel 15 is mounted on the window frame 12 between the root portions of the shielding lips 28 and 29 and the distal ends of the inner peripheral edges 30 and 31 of the window frame 12 in the open state of the window glass 14. For example, a clearance of about 0.3 to 0.8 mm is provided.

Further, the upper glass run channel 15 is integrated with an easily deformable portion 32 that is easily elastically deformed when the upper end surface of the window glass 14 presses the base portion 21 between the base portion 21 and the side wall portion 23 on the outside of the vehicle. It is molded into. The easily deformable portion 32 is formed of the same elastic polymer material as the other portions of the upper glass run channel 15, but has a substantially flat plate shape that is thinner than the thickness of the base portion 21 and the side wall portion 23 on the outside of the vehicle. 2, with the upper glass run channel 15 attached to the window frame 12, the easily deformable portion 32 is obliquely upward from the base portion 21 toward the vehicle exterior (in the diagonally upper right direction in FIG. 2). By being formed to extend, as shown in FIG. 3, when the upper end surface of the window glass 14 presses the base portion 21 toward the outer peripheral side (upper side) of the window frame 12, the displacement of the base portion 21 occurs. Accordingly, the easily deformable portion 32 is bent and deformed so as to rotate upward (the direction of displacement of the base portion 21) with the side wall portion 23 side on the outside of the vehicle as a fulcrum (deformed to rotate clockwise in FIG. 3). It has become. Thereby, when the upper end surface of the window glass 14 presses the base portion 21 and the base portion 21 is displaced in the window frame outer peripheral side direction, an easily deformable portion provided between the base portion 21 and the side wall portion 23 outside the vehicle. 32 is elastically deformed in substantially the same direction as the displacement direction of the base portion 21, and the displacement of the base portion 21 can be absorbed by the elastic deformation of the easily deformable portion 32. Thus, the displacement of the vehicle-side shielding lip 29 connected to the side wall 23 is reduced so as to be pulled into the groove of the window frame 12.

  Here, when the upper end surface of the window glass 14 presses the base portion 21 toward the outer peripheral side of the window frame 12, the force required to elastically deform the easily deformable portion 32 is defined as F1, and the shielding lip 29 on the outside of the vehicle. Is drawn into the groove of the window frame 12 and F2 is a force required to cause opening deformation of the shielding lip 29, the former force F1 is smaller than the latter force F2 (F1 <F2). ), The shape (for example, thickness dimension) of the easily deformable portion 32 is set.

  The upper glass run channel 15 has non-adhesive low friction material layers 21a, 21a, 21a, 21b on the base 21, the side wall 23, and the seal lips 24, 25, respectively, at predetermined locations (locations that come into contact with the window glass 14). 23a, 24a, and 25a are formed. When the upper glass run channel 15 is formed of a thermoplastic elastomer, each of the low friction material layers 21a, 23a, 24a, 25a is mixed with a spherical fine powder of silicone resin, a high molecular weight polyethylene resin powder or the like in the thermoplastic elastomer. The low friction material having a thickness of about 0.05 to 2 mm is fused and integrated to the base portion 21, the side wall portion 23, and the seal lips 24 and 25 by coextrusion molding. On the other hand, when the upper glass run channel 15 is formed of rubber, the low friction material layers 21a, 23a, 24a, and 25a are made of a low friction material such as urethane paint, respectively, the base portion 21, the side wall portion 23, the seal lip 24, 25 is formed by coating.

  These low friction material layers 21a, 23a, 24a and 25a not only reduce sliding resistance against the window glass 14, but also have non-adhesiveness. It functions to prevent the material from adhering to 23. Furthermore, since the low friction material layer 21a improves the sliding in the width direction between the base portion 21 and the window glass 14 when the tip of the window glass 14 comes into contact, the displacement of the easily deformable portion 32 is effectively prevented. Can be done.

  As shown in FIG. 1, a stopper 33 that restricts displacement of the base portion 21 of the upper glass run channel 15 in the direction of the outer periphery of the window frame is provided at a predetermined position (for example, two places in the front and rear) of the window frame 12. Is provided. As shown in FIG. 4, the stopper 33 is formed by bending an elastic metal plate (for example, a spring steel plate or the like), and is elastically engaged and fixed inside the window frame 12.

In the first embodiment described above, the easily deformable portion 32 is provided between the base portion 21 of the upper glass run channel 15 and the side wall portion 23 on the outside of the vehicle. The positional relationship with the highest rising position of the glass 14 is shifted, and the displacement amount of the base portion 21 when the window glass is fully closed is between the root portion of the shielding lip 29 on the vehicle outer side and the lower end portion of the inner peripheral edge 31 of the window frame 12. Even when the clearance is larger than the clearance between the two, the easily deformable portion 32 is easily elastically deformed by a force smaller than the force of pulling the shielding lip 29 into the groove of the window frame 12 in accordance with the displacement of the base portion 21, and the base portion. 21 can be absorbed by the elastic deformation of the easily deformable portion 32, and the displacement that the shielding lip 29 on the outside of the vehicle is pulled into the groove of the window frame 12 can be reduced. Thus, when the window glass is fully closed, it is possible to prevent the shielding lip 29 on the outside of the vehicle from being displaced so as to be pulled into the groove of the window frame 12, and the opening of the shielding lip 29 when the window glass is fully closed. The deformation can be prevented, the sealing performance between the shielding lip 29 and the window frame 12 when the window glass is fully closed can be improved, and the generation of wind noise during traveling can be prevented.

  Generally, it is the upper glass run channel 15 of the glass run channel assembly 13 that the window glass 14 raised to the highest position when the window glass is fully closed is pressed most strongly. Considering the situation that the problem is most likely to occur in the upper glass run channel 15, in the first embodiment, at least the easily deformable portion 32 is provided in the upper glass run channel 15. The problem of opening deformation of the shielding lip 29 can be solved.

  By the way, if a stopper that restricts the displacement of the base portion 21 is provided on the entire portion of the window frame 12 that faces the base portion 21 of the upper glass run channel 15, the opening deformation of the shielding lip 29 can be prevented. 11, since the window frame 12 is integrally formed, the stopper 33 for restricting the displacement of the base portion 21 of the upper glass run channel 15 needs to be attached with a separate part from the window frame 12, and the minimum necessary In general, the stopper 33 is attached only at a location. For this reason, the upper glass run channel 15 mounted on the window frame 12 of the panel door 11 has many portions where the stopper 33 is not disposed. In many of these portions, the effect of the stopper 33 does not reach and the displacement of the base portion 21 is not achieved. When the amount is increased and the easily deformable portion 33 is not provided, the shielding lip 29 may be deformed by opening.

  In consideration of such circumstances, in the first embodiment, the upper glass run channel 15 attached to the window frame 12 of the panel door 11 (that is, in many portions, the shielding lip 29 may be deformed by opening). Since the present invention is applied to the upper glass run channel 15) to provide the easily deformable portion 32 to prevent the opening deformation of the shielding lip 29, the effect of applying the present invention is great. However, the present invention is not limited to the above, and can be applied to a window frame in which the stopper 33 is formed over the entire length of the upper glass run channel 15. In this case, the effect of the present invention is further improved. Can be presented.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. However, substantially the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be simplified. The parts different from the first embodiment will be mainly described.

As shown in FIG. 5, the upper glass run channel 34 of the second embodiment has substantially the same shape as the upper glass run channel 15 of the first embodiment, and the entire (or part) of the easily deformable portion 35 is formed on the side wall portion. It is formed integrally with a polymer material that is softer and easier to stretch than the materials of the materials 22 and 23 and the base portion 21. The polymer material that forms the easily deformable portion 35 is, for example, a softer rubber or a soft thermoplastic elastomer than the base portion 21 and the side wall portions 22 and 23 (more rubber component than the rubber component in the material of the side wall portions 22 and 23). Many thermoplastic elastomers) or foamed rubber, TPE, or the like is used, and the easily deformable portion 35 is fused and integrated with the base portion 21 and the side wall portion 23 on the vehicle outer side by coextrusion molding.

In the second embodiment described above, at least a part of the easily deformable portion 35 is integrally formed of a polymer material that is more flexible and stretchable than the side wall portions 22 and 23 and the base portion 21, so that it can be easily and reliably performed. The easily deformable portion 35 that is deformed can be formed, and the effect of preventing the opening lip deformation of the shielding lip 29 can be enhanced. In addition, 21a, 23a, 24a, and 25a are the low friction material layers similar to the first embodiment.

In the second embodiment, the same shape as the upper glass run channel 15 of the first embodiment, and at least a part of the easily deformable portion 35 is made of a polymer material that is more flexible and easier to extend than the side walls 22, 23 and the base portion 21. However, it has the same shape as the conventional upper glass run channel (see FIG. 9), and at least a part between the base portion and the side wall portion is more flexible than the side wall portion and the base portion. The easily deformable portion may be integrally formed between the base portion and the side wall portion by forming the polymer material that is easily stretched.

  Next, Embodiment 3 of the present invention will be described with reference to FIGS. However, substantially the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be simplified. The parts different from the first embodiment will be mainly described.

As shown in FIGS. 6 and 7, the upper glass run channel 36 of the third embodiment has the same external shape as the upper glass run channel 15 of the first embodiment, and projects from the base portion 37 to the end face side of the window glass 14. The base portion 37 is composed of an outer peripheral wall 37a facing the outer peripheral side of the window frame, and an inner peripheral wall 37b facing the upper end side of the window glass 14 through the hollow portion 50, along the longitudinal direction. It is integrally formed by coextrusion molding, and the inner peripheral wall 37b is thinner than the thickness of the side wall portion 23 on the vehicle outer side and the outer peripheral wall 37a. The inner peripheral wall 37b serves as a glass contact portion that can be easily deformed .

In the third embodiment described above, the base portion 37 is formed into a hollow shape, and a glass contact portion 37b (inner peripheral wall 37b) that can be easily deformed into a portion of the base portion 37 that contacts the upper end surface of the window glass 14. Therefore, the displacement of the base portion 37 when the window glass is fully closed is changed only to the glass contact portion 37b of the base portion 37 which is almost easily deformable or the easily deformable portion 32 as in the first embodiment. The displacement of the shielding lip 29 being pulled into the groove of the window frame 12 can be reduced, and the opening deformation of the shielding lip 29 can be prevented.

In the third embodiment, the glass abutment portion 37b that has the same external shape as the upper glass run channel 15 of the first embodiment and is easily deformed on the inner peripheral wall of the base portion 37 by forming the hollow portion 50 in the base portion 37. However, with the same external shape as the conventional upper glass run channel (see FIG. 9), the base portion is formed into a hollow shape to form a glass contact portion 37b that is easily deformed on the inner peripheral wall of the base portion. You may make it do. Further, the easily deformable glass contact portion 37b (the inner peripheral wall 37b of the hollow base portion 37) may be formed of a polymer material that is more flexible and easier to extend than the outer peripheral wall 37a of the base portion 37. On the contrary, the outer peripheral wall 37a may be formed of a polymer material that is thinner or more flexible and easily stretched than the inner peripheral wall 37b or the side wall portion 23 on the outside of the vehicle. Further , the entire inner peripheral wall 37b may be a glass contact portion that is easily deformable, or only a part thereof may be a glass contact portion that is easily deformable . 6 and 7, reference numerals 23a, 24a, 25a, and 37c are low friction material layers similar to those in the first embodiment.

  In each of the first to third embodiments, as shown in FIG. 8, a fitting groove 39 is formed on the bottom surface of the concave groove 27 formed between the side wall portion 23 on the vehicle outer side and the shielding lip 29. The fitting portion 40 is formed at the lower end portion of the inner peripheral edge 31 on the vehicle outer side of the window frame 12, and the fitting portion 40 of the inner peripheral edge 31 of the window frame 12 is fitted into the fitting groove 39 of the concave groove 27. Thus, the bottom surface of the groove 27 may be prevented from sliding in the width direction with respect to the inner peripheral edge 31 of the window frame 12.

  In this way, even if the base portion of the shielding lip 29 is about to be displaced toward the outer peripheral side of the window frame 12, the fitting portion 40 of the inner peripheral edge 31 of the window frame 12 and the groove 27 are fitted. By fitting with the groove 39, the shielding lip 29 can be prevented from being drawn into the groove of the window frame 12, and the effect of preventing the opening deformation of the shielding lip 29 can be further enhanced.

  In each of Examples 1 to 3, the upper glass run channel is provided with an easily deformable portion. However, a glass run channel other than the upper glass run channel (front side glass run channel, rear side glass run channel, front side A corner glass run channel, a rear corner glass run channel, etc.) may be provided with an easily deformable portion.

  In addition, the scope of application of the present invention is not limited to the glass run channel mounted on the window frame of the panel door, but is widely applied to the glass run channel mounted on the window frame of an automobile door such as a sash type sash door. Can be implemented. The present invention can also be applied to the prevention of opening deformation of the shielding lip inside the vehicle.

It is a schematic block diagram of the panel door in Example 1 of this invention. It is a figure which shows the state which has a window glass in the downward direction rather than the highest position in AA sectional drawing of FIG.
