Description

  The present invention relates to a wind seal structure for a vehicle, and more particularly, to a seal member that can be sealed by contact with a window glass in a closed state, an extension portion that extends in the outward direction of the window opening is provided along the outer surface of the side wall portion of the window opening frame member. The present invention relates to a vehicle wind seal structure.

  Conventionally, when the vehicle is running, the air pressure around the vehicle body is reduced and a differential pressure is generated inside and outside the vehicle compartment, so that air is sucked out of the vehicle compartment through the gap between the window glass and the door sash. It is known that indoor noise (suction sound) is generated, and this suction sound tends to increase as the vehicle runs at high speed. Therefore, a resin glass run that slides and guides the raising and lowering of the window glass is secured to the window opening of the front door and the rear door of the vehicle while ensuring the sealing property of the window glass. This glass run is usually constituted by a groove-forming portion having a substantially U-shaped cross section fixed to the door sash, and an outer lip and an inner lip that are projected from the groove-forming portion toward the wind glass.

  A press door in which a door sash, which is a window opening frame member, is press-molded integrally with the door main body, and the door sash and the door main body are compared with a sash door in which the door sash is configured separately from the door main body. Can be omitted, and it is advantageous in terms of productivity, component rigidity, design, etc., but on the other hand, it is difficult to integrally form a glass run support with a complicated shape by press molding. Exists. Therefore, various glass run attachment structures for attaching the glass run to the press door have been proposed.

  The mounting structure of the glass run of Patent Document 1 is a door sash for a decorative molding material integrally formed with a channel portion having a substantially U-shaped cross section for fitting the mounting base portion of the glass run inward via a caulking pin or a grip. It is fixed to the flange part extending from In this glass run mounting structure, it is necessary to newly design a molding material, a caulking pin for fixing the molding material to the flange portion, etc., resulting in an increase in the number of parts and an increase in manufacturing cost. Therefore, a glass run mounting structure that directly attaches a glass run to a door sash without increasing the number of parts is also known.

  As shown in FIG. 7, the corner structure of the door glass run of Patent Document 2 includes a door sash 51 of a press door in which an outer panel 52 and an inner panel 53 are joined, and the outer panel 52 and the inner panel 53 are arranged inside the window opening. The glass run mounting flange portion 54 is joined to form a glass run mounting portion 54 having an outer lip 57 capable of coming into contact with the window glass 60 from the outside, and the glass run mounting flange portion 54 is fixed to the glass run mounting flange portion 54. The structure provided with the fixing | fixed part 59 which has the inner lip 58 which can contact | abut to the glass 60 from the inside is disclosed.

In general, as a design requirement for a glass run, it is required to satisfy both conflicting performances.
In terms of securing the sealability in the vehicle interior, the higher the contact force between the glass run and the window glass, the higher the sealability between the window glass and the door sash, and the lowering the suction sound.
However, in terms of the sliding guide of the wind glass, the higher the contact force between the glass run and the wind glass, the greater the sliding resistance when the window glass is raised and lowered, so the load for opening and closing the wind glass increases. The guide performance of wind glass is hindered.

JP 2007-302172 A JP 2000-71780 A

The corner portion structure of the door glass run of Patent Document 2 is a structure in which the glass run 55 is directly fixed to the glass run mounting flange portion 54, and the sealing performance in the vehicle interior and the guide performance of the wind glass 60 are particularly important. It is not considered and merely discloses the outer lip 57 and the inner lip 58 that abut against the window glass 60.
However, in the structure disclosed in Patent Document 2, the groove forming portion 56 of the glass run 55 is configured to be deformable by the displacement of the window glass 60 when a force in the orthogonal direction such as traveling negative pressure acts on the window glass 60. By doing so (hereinafter referred to as a deformed structure), the contradictory performance of the glass run can be achieved.

That is, when the traveling negative pressure acts on the deformed window glass 60 in the vehicle width direction outer side, the window glass 60 is displaced in the vehicle width direction outer side, so that the window glass 60 is displaced with respect to the outer lip 57. Force that goes toward the outside in the vehicle width direction is generated.
As shown in FIG. 7, a force F <b> 1 directed toward the outer side in the vehicle width direction is applied to the outer lip 57 based on the displacement of the window glass 60, and the force is applied to the glass run mounting flange portion 54 via the groove forming portion 56. A force F2 directed inward in the vehicle width direction, which is a reaction force of F1, acts.

In this modified structure, the glass run mounting flange portion 54 is disposed on the inner side of the window opening than the outer lip 57, and the fixing portion 59 for fixing the glass run 55 to the glass run mounting flange portion 54 is more open than the outer lip 57. Since the distance L is arranged inwardly, the counterclockwise moment M around the fixing portion 59 is generated in the groove forming portion 56 of the glass run 55, and this moment M causes the counterclockwise moment in the groove forming portion 56. A deformation that curves in the direction of rotation occurs. Thereby, the contact force with which the outer lip 57 contacts the window glass 60 can be increased. Further, since the moment M increases as the vehicle speed increases, the contact force with which the outer lip 57 contacts the window glass 60 can be increased in proportion to the increase in the vehicle speed.
Therefore, when the fixing portion 59 of the glass run 55 is disposed at a distance L away from the outer lip 57 to the inside of the window opening, the sealing performance of the glass run 55 can be enhanced by using the vehicle speed (traveling negative pressure). Therefore, it is possible to suppress the generation of suction sound during high-speed travel without increasing the sliding resistance of the window glass 60 when the vehicle is stopped or during low-speed travel.

As described above, the deformable structure can achieve both the sealing performance in the vehicle interior and the guide performance of the window glass by using the traveling negative pressure. However, in this modified structure, since the fixing portion 59 for fixing the glass run 55 is arranged at a distance L from the outer lip 57 to the inside of the window opening, the following new problem may be caused.
That is, since a counterclockwise moment M centering on the fixing portion 59 is generated in the groove forming portion 56 of the glass run 55, the groove forming portion 56 is curved and deformed inward toward the window opening, and the groove forming portion 56 and the outer panel 52 are deformed. There may be a gap between the vertical wall portion 52a and the vertical wall portion 52a that does not occur when the vehicle stops or travels at a low speed. This gap causes a drop in merchantability due to deterioration in appearance, and in particular, the gap increases as the vehicle travels at a high speed, which may affect the penetration of rainwater and the like, and the support rigidity of the glass run.

Further, in order to improve the sealing performance between the glass run 55 and the window glass 60, it is desirable to form the glass run 55 with a flexible elastic material such as rubber. However, when the glass run 55 is formed of a flexible elastic material and the moment M is applied to the glass run 55 using the vehicle speed (traveling negative pressure), the base end portion of the groove forming portion 56 is directed toward the inside of the window opening. Although it is curved and deformed, the outer lip 57 is locally deformed outward in the vehicle width direction. As a result, there is a possibility that the outer lip 57 cannot be brought into close contact with the wind glass 60 over the entire area.
Therefore, it is conceivable that a relatively high-rigidity frame member for mounting the glass run is separately provided as in the glass run mounting structure of Patent Document 1, and local deformation of the outer lip is suppressed by this frame member. However, in Patent Document 1, as described above, a moment is generated in the glass run by using the vehicle speed (traveling negative pressure), and no improvement is considered for improving the sealing performance by this moment. In order to adopt, there are problems to be solved such as a fixing structure for fixing the glass run and the frame member integrally to the outer panel.

  An object of the present invention is to provide a vehicle wind seal structure capable of preventing appearance deterioration while achieving both sealing performance in a vehicle cabin and wind glass guide performance.

  The vehicle window seal structure according to claim 1 is a windshield that can be opened and closed in the vertical direction, and a seal that can be sealed by contacting the window glass in a closed state, which is formed by an outer panel and an inner panel. In the vehicle wind seal structure provided with a member, an outer panel of a vertical frame portion extending in a substantially vertical direction of the window opening includes a side wall portion forming an outer wall in the vehicle width direction, and a vehicle opening from an inner end of the window opening of the side wall portion. An inner panel inner side having a vertical wall part extending inward in the width direction and an outer panel inner flange part extending inward from the vertical wall part toward the window opening inner side, wherein the inner panel of the vertical frame part is joined to the outer panel inner flange part A flange portion, wherein the seal is formed by the outer panel inner flange portion and the inner panel inner flange portion. Forming a support portion for supporting a material, and the seal member is a groove forming portion that can be deformed by displacement of the window glass when a force in an orthogonal direction is applied to the window glass, and A groove forming portion having a seal portion capable of coming into contact with the window glass from the outside in the vehicle width direction, a fixed portion fixed to the support portion on the inner side of the window opening than the seal portion, and the side wall portion from the groove forming portion. An extension portion extending outwardly of the window opening along the outer surface, the seal member includes a glass run and a garnish having rigidity higher than that of the glass run, and the groove forming portion is a first groove forming portion of the glass run. And the second groove forming portion of the garnish that is positioned in proximity to the outside of the window opening of the first groove forming portion, and the fixing portion is fixed to the support portion. -A finish side fixing portion and a glass run side fixing portion for fixing the garnish side fixing portion to the support portion, and the garnish extends from the second groove forming portion along the outer surface of the side wall portion to the outside of the window opening. A garnish main body extending in the direction is provided.

  In this vehicle wind seal structure, the seal member is a groove forming portion that can be deformed by the displacement of the wind glass when a force in the orthogonal direction acts on the wind glass, and the wind glass extends in the vehicle width direction at the inner end of the window opening. A groove forming portion having a seal portion that can be contacted from the outside, and a fixing portion fixed to a support portion formed by an outer panel inner flange portion and an inner panel inner flange portion inside the window opening from the seal portion. Therefore, when running at high speed, a moment is generated in the groove forming part around the fixed part in the groove forming part using the running negative pressure, and the window glass of the seal part is deformed by the groove forming part in the inner direction of the window opening. It is possible to increase the abutting force that abuts against.

According to a second aspect of the present invention, in the first aspect of the invention, an outer panel outer flange portion formed at a window opening outer end portion of the outer panel of the vertical frame portion and a window opening outer end portion of the inner panel of the vertical frame portion. An inner panel outer flange portion joined to the outer panel outer flange portion, and the outer panel outer flange portion and the inner panel outer flange portion form an engaging portion of the seal member, and a window opening of the garnish main body portion The outer end portion is supported by the engagement portion, and the support force of the seal member by the support portion is set larger than the support force of the seal member by the engagement portion.

According to a third aspect of the present invention, in the second aspect of the invention, the window opening outer end of the garnish main body is engaged with the engaging portion so that the garnish main body can be displaced along the outer surface of the side wall. It is characterized by that.
The invention of claim 4 is characterized in that, in the invention of any one of claims 1 to 3, the vertical wall portion of the outer panel of the vertical frame portion is configured to form an obtuse angle with the side wall portion.

According to the first aspect of the present invention, when traveling at a high speed, a moment in the window opening inside direction around the fixed portion is generated in the groove forming portion using the traveling negative pressure, and the deformation in the window opening inside direction by the groove forming portion is generated. This increases the contact force of the seal part against the window glass, ensuring both sealing performance in the passenger compartment and the guide performance of the window glass, and due to the moment in the wind opening inner direction, between the groove forming part and the outer panel Since the gap which generate | occur | produces is shielded by the extension part, appearance deterioration can be prevented and merchantability can be improved.
The glass run can be positioned in the vertical frame part by the exterior garnish without hindering the sealing function of the glass run, and the second groove forming part generated due to the moment in the wind opening inner direction by the garnish body part of the design surface The gap between the outer panel and the outer panel can be shielded. Moreover, in addition to the moment in the window opening inner side generated in the first groove forming portion, the moment in the window opening inner direction generated in the second groove forming portion can be applied to the seal portion of the glass run. Can be high.
Moreover, since the garnish is more rigid than the glass run, when running negative pressure is applied to the wind glass during high-speed running, the garnish is localized in the glass run due to running negative pressure compared to the case where only the glass run is provided. The general deformation. Therefore, the traveling negative pressure can be reliably applied to the glass run as a moment in the direction toward the inside of the window opening.

According to the invention of claim 2, the garnish can be attached to the vertical frame portion with a simple structure without hindering the effect of improving the sealing performance.
According to invention of Claim 3, the attachment rigidity of a garnish is securable, without inhibiting the deformation | transformation centering on the garnish side fixing | fixed part by a 2nd groove | channel formation part.
According to the invention of claim 4, even if the door sash is a press door which is press-molded integrally with the door body, both productivity and sealability of the wind glass can be achieved.
That is, since the press door is formed by press molding, it is difficult to form the vertical wall portion and the side wall portion of the outer panel of the vertical frame portion at a steep angle. In the case of such an outer panel structure, when a running negative pressure is applied to the window glass during high-speed running, the glass run is likely to be displaced to the outside of the vertical frame portion , and the need for improved sealing performance during higher-speed running increases. . Therefore, in a press door in which it is difficult to form the vertical wall portion and the side wall portion of the outer panel at a steep angle, it is possible to satisfy the needs for improving the sealing performance during high-speed traveling.

  DESCRIPTION OF EMBODIMENTS Hereinafter, modes for carrying out the present invention will be described based on examples applied to a front door of a vehicle. In the figure, the directions of the arrows F and R will be referred to as the front-rear direction, and the directions of the arrows IN and OUT will be described as the directions outside the vehicle interior.

First, a reference technique as a premise of the present invention will be described with reference to FIGS.
As shown in FIG. 1, a front door 1 of a vehicle having a window seal structure of reference technology is a press door in which a main body portion 2 and a door sash 3 constituting a window opening 4 are integrally formed by press molding. . Since the right front door has a symmetrical structure with the left front door 1, the left front door 1 will be mainly described below.

The front door 1 is formed as a single structure having a closed cross section by a steel plate outer panel constituting a door outer wall and a steel plate inner panel constituting a vehicle interior wall.
Inside the main body 2, a window glass 5 capable of opening and closing the window opening 4 in the vertical direction, a window driving unit and an acoustic unit (not shown) for driving the window glass 5 up and down, an impact bar (not shown), and the like Is equipped.

The door sash 3 is attached with a glass run 10 made of resin over the entire inner edge portion thereof, and also has a front frame portion 3a extending rearwardly from the upper end of the front portion of the main body 2 and extending in an inclined manner, and the front frame portion 3a. An upper frame portion 3b extending horizontally from the rear end of the rear frame portion, and a rear frame portion 3c (vertical frame portion) extending downward in the vertical direction from the rear end of the upper frame portion 3b toward the rear upper end of the main body portion 2. ing.
Since the glass run 10 is mounted in the same configuration on the inner edges of the frame parts 3a, 3b, 3c, the rear frame part 3c will be mainly described below.

As shown in FIG. 2, the outer panel 6 of the rear frame portion 3c constitutes an inner flange portion 6a extending forward (inward direction of the window opening) and a rear end portion (outer end portion of the window opening) extending rearward. An outer flange portion 6b that extends forward from the front end of the outer flange portion 6b to form an outer wall in the vehicle width direction of the vehicle body, and an inner flange portion from the front end (wind opening inner end) of the side wall portion 6c. The vertical wall portion 6d extends inward in the vehicle width direction along the rear end of 6a.
The vertical wall portion 6d is formed so as to move rearward (wind opening outer side direction) toward the outer side in the vehicle width direction, and is configured to form an obtuse angle of 90 ° or more with respect to the side wall portion 6c. Specifically, since the outer panel 6 and the inner panel 7 described later are formed by press molding, if the vertical wall portion 6d and the side wall portion 6c are formed at a steep angle, it is difficult to detach the panel from the press die at the time of press molding. become. Therefore, in the case of the front door 1 that is a press door, when a running negative pressure is applied to the wind glass 5 during high speed running, the edge of the glass run 10 is likely to be displaced to the outside of the door sash 3. The need for improved sealing performance at high speeds increases.

The inner panel 7 of the rear frame portion 3c is overlap-welded with the inner flange portion 6a and extends forward, and the outer flange portion 7b connected to the outer flange portion 6b and constituting the rear end portion of the inner panel 7. And a side wall portion 7c formed from the rear end of the inner flange portion 7a to the front end of the outer flange portion 7b and bulging inward.
The inner flange portion 7a constitutes a support portion 8 for supporting the glass run 10 on the rear frame portion 3c (door sash 3) in cooperation with the inner flange portion 6a. The outer flange portion 7b is connected to the outer flange portion 6b by a hemming process in which the outer flange portion 7b is joined while being sandwiched between the outer flange portions 6b.

Next, the glass run 10 will be described.
As shown in FIG. 2, the glass run 10 includes a groove forming portion 11 having a substantially U-shaped cross-section opened forward, a fixing portion 12 having a substantially U-shaped cross-section opened rearward, and an outer portion of the groove forming portion 11. And an extension portion 13 extending rearward from the rear, and is integrally formed of a resin material having elasticity such as rubber.
The glass run 10 is attached to the door sash 3 so as to continuously extend along the inner edges of the respective frame portions 3a, 3b, 3c.

When the groove forming portion 11 is attached to the rear frame portion 3c and a force in the orthogonal direction (vehicle width direction) acts on the wind glass 5 due to traveling negative pressure or the like, the groove forming portion 11 moves in the vehicle width direction by the wind glass 5. When the force is not applied to the window glass 5, the bottom portion of the groove forming portion 11 is configured to be in close contact with the vertical wall portion 6d.
An outer lip portion 11a (seal portion) capable of coming into contact with the closed window glass 5 from the outside is formed on the outer side and the front end (wind opening inner end) of the groove forming portion 11. The distal end portion of the outer lip portion 11 a is bent rearward at a position behind the support portion 8, and the inner portion thereof is in contact with the outer surface of the window glass 5.

As shown in FIG. 2, the fixing portion 12 is configured to be continuous with the inner front end portion of the groove forming portion 11 at a position ahead of the outer lip portion 11a.
A core metal 14 having a substantially U-shaped cross section having an elastic force for sandwiching the support portion 8 is embedded in the fixed portion 12, and the support portion 8 is sandwiched via a plurality of convex portions 12 a, thereby allowing the glass run. 10 is fixed to the rear frame portion 3c.

  An inner lip portion 12b is formed at the front end portion of the fixed portion 12 so as to be able to contact the closed window glass 5 from the inside. The front end portion of the inner lip portion 12b is curved rearward, and the outer portion thereof is in contact with the inner surface of the window glass 5 at a position facing the front end portion of the outer lip portion 11a. As described above, as shown in FIG. 2, the fixing portion 12 for fixing the glass run 10 is disposed at a predetermined distance L away from the abutting portion between the outer lip portion 11a and the window glass 5, and thus traveling. When a force F1 in the outer orthogonal direction acts on the window glass 5 due to negative pressure or the like, a force F2 in the inner orthogonal direction, which is a reaction force of the force F1, is generated through the groove forming portion 11, and the groove forming portion 11 A counterclockwise moment M about the fixed portion 12 is generated. Due to this moment M, the groove forming portion 11 is deformed to be bent in the counterclockwise direction, and the contact force between the outer lip portion 11a and the window glass 5 is increased.

  The extension portion 13 is configured to cover the outer surface of the side wall portion 6c in a close contact manner from the outer portion of the groove forming portion 11 and to extend rearward along the outer surface. As a result, when a gap is generated between the groove forming portion 11 and the vertical wall portion 6d due to the deformation of the groove forming portion 11 in the counterclockwise direction, the extending portion 13 extending rearward is a deformation of the groove forming portion 11. Following this, it moves forward and covers the gap from the outside to shield it from the outside.

Next, functions and effects of the vehicle wind seal structure according to the reference technology will be described.
According to the wind seal structure of this vehicle, when traveling at high speed, a moment M in the counterclockwise direction around the fixed portion 12 is generated in the groove forming portion 11 using the traveling negative pressure, and the groove forming portion is generated. 11 increases the abutting force of the outer lip portion 11a in contact with the window glass 5 due to the counterclockwise deformation in the counterclockwise direction, so that both the sealing performance in the vehicle interior and the guide performance of the window glass 5 can be achieved. The gap generated between the groove forming portion 11 and the vertical wall portion 6d of the outer panel 6 due to the directional moment M is shielded by the extension portion 13, so that the appearance can be prevented from being deteriorated and the merchantability can be improved. .

Since the outer lip portion 11a is configured as the glass run 10 in which the groove forming portion 11, the fixing portion 12, and the extension portion 13 are integrally formed, the single glass run 10 is directly attached to the door sash 3 without increasing the number of parts. Can be installed.
Since the outer lip portion 11a continuously extends along the extending direction of the rear frame portion 3c, the mounting rigidity of the fixing portion 12 with respect to the support portion 8 and the shielding effect by the extending portion 13 are determined in the extending direction of the rear frame portion 3c. It can be obtained stably without interruption.

  Since the vertical wall portion 6d of the outer panel 6 of the door sash 3 is configured to form an obtuse angle with the side wall portion 6c, even if the door sash 3 is a press door integrally formed with the main body portion 2, And the sealing property of the wind glass 5 can be made compatible. That is, since the press door is formed by press molding, it is difficult to form the vertical wall portion 6d and the side wall portion 6c of the outer panel 6 of the door sash 3 at a steep angle. In the case of such an outer panel structure, when a traveling negative pressure is applied to the window glass 5 during high-speed traveling, the edge of the glass run 10 is likely to be displaced to the outside of the door sash 3, and sealing performance during further high-speed traveling is achieved. Improvement needs are high. Therefore, in the press door in which it is difficult to form the vertical wall portion 6d and the side wall portion 6c of the outer panel 6 at a steep angle, it is possible to satisfy the need for improving the sealing performance at the time of high speed traveling by the above configuration.

Next, a vehicle wind seal structure according to the first embodiment will be described with reference to FIGS. Only the configuration different from the above-described reference technique will be described, and the same members as those in the reference technique are denoted by the same reference numerals and description thereof will be omitted.
In the reference technique, the sealing member is constituted by the glass run 10 provided with the extension 13. However, in the first embodiment, the sealing member is made of a rubber glass run 20 and a synthetic resin decoration higher in rigidity than the glass run 20. The garnish 30 is used.

As shown in FIGS. 3 to 5, the glass run 20 has a first groove forming portion 21, a glass run side fixing portion 22, and the like integrally formed, and a synthetic resin garnish 30 has a second groove forming portion 31 and the like. The garnish side fixing portion 32, the garnish main body portion 33 and the like extending rearward from the outer portion of the second groove forming portion 31 along the outer surface of the side wall portion 6c are integrally formed.
An outer lip portion 21a is provided at the outer front end portion of the first groove forming portion 21 so as to be able to come into contact with the closed window glass 5 from the outside, and an outer lip portion 21a is provided at the outer front end portion of the second groove forming portion 31. A garnish front end 31a that can be pressed from the outside is provided.
The glass run side fixing portion 22 is formed with a plurality of convex portions 22a and an inner lip portion 22b that can contact the closed window glass 5 from the inside at the front end portion thereof.

  The groove forming portion 11 </ b> A of the sealing member includes a first groove forming portion 21 and a second groove forming portion 31 that is disposed close to the outside of the first groove forming portion 21 and can be fitted into the first groove forming portion 21. It consists of and. These first and second groove forming portions 21 and 31 are mounted on the rear frame portion 3c, and when a force in the orthogonal direction acts on the wind glass 5 due to traveling negative pressure or the like, When it is deformed forward by displacement in the width direction and no force acts on the window glass 5, the bottom portion of the second groove forming portion 31 is in close contact with the vertical wall portion 6 d and the bottom portion of the first groove forming portion 21. Closely adheres to the bottom of the second groove forming portion 31.

  The sealing member fixing portion 12 </ b> A includes a garnish side fixing portion 32 fixed to the support portion 8 and a glass run side fixing portion 22 that fixes the garnish side fixing portion 32 to the support portion 8. The garnish side fixing portion 32 is formed so as to be continuous with the inner front end portion of the second groove forming portion 31 at a position in front of the garnish front end portion 31a, and the glass run side fixing portion 22 is positioned at a position in front of the outer lip portion 21a. It is formed to be continuous with the inner front end portion of the one groove forming portion 21. The glass run side fixing | fixed part 22 is clamping the support part 8 and the garnish side fixing | fixed part 32 via several convex part 22a.

  As described above, as shown in FIG. 5, the fixing portion 12A is arranged at a predetermined distance L away from the abutting portion of the outer lip portion 21a and the window glass 5, so that the wind glass 5 is moved to the window glass 5 by a traveling negative pressure or the like. On the other hand, when the force F1 in the outer orthogonal direction is applied, a force F2 in the inner orthogonal direction, which is a reaction force of the force F1, is generated via the first and second groove forming portions 21 and 31 (groove forming portion 11A). The first and second groove forming portions 21 and 31 generate a counterclockwise moment M centering on both the fixing portions 22 and 32 (fixing portion 12A). Due to these moments M, the first and second groove forming portions 21 and 31 are deformed to curve forward in the counterclockwise direction. As a result, the outer lip portion 21a is brought into contact with the window glass 5 with a pressing force obtained by combining the pressing force of the outer lip portion 21a and the pressing force of the garnish front end portion 31a.

  Further, since the garnish 30 is higher in rigidity than the glass run 20, when a traveling negative pressure is applied to the wind glass 5 during high speed traveling, the garnish 30 has a traveling negative pressure compared to the case where only the glass run 20 is provided. The local deformation of the glass run 20 caused by the moment M generated by the is suppressed. Furthermore, since the glass run 20 is formed of a material having a relatively low rigidity, the adhesion between the wind glass 5 and the glass run 20 can be improved, and a sealing property can be secured over the entire area of the glass run 20.

As shown in FIGS. 3 to 5, the garnish main body portion 33 as a design surface has an engaged portion 33 a for supporting the garnish main body portion 33 at the rear end portion so as to be displaceable along the outer surface of the side wall portion 6 c. Are formed, and stepped step portions 33b are formed at the upper end portions, respectively.
The engaged portion 33a is formed to have a substantially J-shaped cross section, and can be engaged with the engaging portion 9 formed by the outer flange portions 6b and 7b in a state where a gap is formed.

The support force for fixing the glass run 20 and the garnish 30 by the support part 8 is set larger than the support force of the glass run 20 and the garnish 30 by the engaging part 9.
Thus, when a gap is generated between the second groove forming portion 31 and the vertical wall portion 6d due to the deformation in the counterclockwise direction by the first and second groove forming portions 21 and 31, the garnish extends backward. The main body portion 33 moves forward following the deformation of the second groove forming portion 31, covers the gap from the outside, and shields it from being visually recognized from the outside.

As shown in FIG. 4, the garnish 30 continuously extends in the vertical direction along the rear frame portion 3 c, and the stepped portion 33 b is configured to be connectable to the garnish 40 at the upper end thereof.
Similar to the garnish 30, the garnish 40 includes a groove forming portion 41, a fixing portion 42, a garnish main body portion 43, and the like. At the rear end portion of the groove forming portion 41, a rectangular cutout portion 44 into which the step portion 33b of the garnish 30 is inserted is formed.
