Description

Automotive window glass bracket

The present invention relates to an automobile glass bracket, a glass module, a door structure, and an automobile window glass fixing method.

Conventionally, window glass that does not move up and down, such as a windshield and a rear window, has been fixed to the vehicle body using an adhesive (for example, Patent Document 1). Specifically, an adhesive is applied to the entire periphery of the window glass and fixed to the window frame portion of the vehicle body. Thereafter, a waterproof member such as a glass run is attached between the window glass and the window frame. On the other hand, a window glass that moves up and down, such as a side glass, is fixed to a lifting mechanism such as a window regulator device using a screw (for example, Patent Document 2). Specifically, first, the window glass is inserted from above between the inner plate and the outer plate of the door structure, and screwed to the lifting mechanism disposed inside the door structure. And after raising a window glass and fitting a window glass in the guide groove of a window frame part, a waterproofing member is attached to the clearance gap between a window glass and a window frame part.

No. 07-015768 JP-A-10-169306

By the way, when the side glass is not raised and lowered, the raising and lowering mechanism becomes unnecessary, so that the price can be reduced and the fuel consumption can be reduced by reducing the weight. Therefore, in recent years, a vehicle type in which the side glass does not move up and down has been studied. On the other hand, since the side glass which raises / lowers may be desired, it is possible to make the door structure which a side glass does not raise / lower as a standard specification, and to make the raising / lowering mechanism of a side glass optional. In this case, even if it is the same vehicle type, the vehicle which has a raising / lowering mechanism and the vehicle which does not have are mixed.

When the window glass is not raised and lowered, the window glass is fixed using an adhesive as in Patent Document 1, while the window glass is fixed to the lifting mechanism as in Patent Document 2 to raise and lower the window glass. However, this is not desirable from the viewpoint of sharing parts. For example, even when the window glass is not raised or lowered, the window glass is accommodated in the door structure in the same manner as when the window glass is raised and lowered, instead of applying the adhesive to the entire periphery of the window glass and fixing it to the window frame. After that, it is desirable to attach it by sliding it upward and fixing it to the window frame.

By the way, when referring to the accuracy of the position where the side glass is attached, the accuracy of the vertical position is not a big problem when the side glass is moved up and down. This is because even after the side glass is attached, the side glass can be moved by operating the elevating mechanism, so that the accuracy in the vertical direction of the initial position is not a big problem.

On the other hand, glass that does not have an elevating mechanism cannot be changed in position once it is attached, so the accuracy of the attachment position is required. However, from the viewpoint of the common use of the components described above, even if the lifting mechanism is not provided, if the same mounting method as that used is employed, the positional accuracy cannot be secured, which is a problem.

The present invention was made to solve the above problems, and when fixing the window glass to the door structure so as not to be raised or lowered, the bracket, the glass module, which can improve the accuracy of the mounting position of the window glass, It aims at providing the fixing method of a door structure and a window glass for motor vehicles.

A first bracket according to the present invention is a bracket used for fixing a window glass for an automobile to a door body of a vehicle body by a fixture so as not to be lifted and lowered, and is connected to the bracket body and the bracket body. A supporting portion that supports the glass; and at least one engaging portion that is attached to the bracket main body, engages with an engaged portion provided in the door main body, and positions the window glass, The bracket body is configured to be fixed to the door body by a fixture.

According to this configuration, since the engaging part is provided in the bracket body, after the window glass is supported by the support part, if the engaging part of the bracket body is engaged with the engaged part of the door structure, The window glass can be positioned on the door body. Thereafter, the bracket main body or the support portion can be fixed to the door main body by a fixing tool. Therefore, even when the window glass is fixed to the door body so that it cannot be moved up and down, the window glass can be fixed after being positioned with respect to the door body. Position accuracy can be improved.

The second bracket according to the present invention has an inner plate and an outer plate, and has a space in which the window glass can be accommodated between the inner plate and the outer plate, and the window glass can be raised or lowered. A bracket for fixing a window glass to the door structure by a fixture so as not to be raised or lowered with respect to a door body that can be selected to be attached to the bracket body, and is connected to the bracket body and the bracket body. And a support portion that is attached to the bracket body, engages with an engaged portion provided on an inner plate of the door body, and positions the window glass. The bracket body or the support portion is configured to be fixed to the door body by a tool.

The third bracket according to the present invention is a bracket used for fixing an automotive window glass to a door body of a vehicle body by a fixture, and is connected to the bracket body and the bracket body, and the window glass And a support portion that is attached to the bracket main body, engages with an engaged portion provided on the door main body, and positions the window glass. The bracket body or the support portion is configured to be fixed to the door body by a tool. The third bracket is not intended for a door body in which a window glass is raised and lowered and for a window glass that is not raised or lowered, and is intended for a door body having a structure in which the window glass is not raised or lowered.

Each bracket may further include a fixing portion to which the fixing tool can be attached. Thereby, for example, after the bracket is positioned with respect to the door structure by the engaging portion, the bracket can be fixed to the door body by attaching the fixing tool to the fixing portion.

In this case, for example, the fixing portion may have a female screw, and the fixing tool may have a male screw that is screwed into the female screw. That is, the bracket can be fixed to the door main body by screwing the male screw of the fixture into the female screw of the fixing portion via the door main body.

In each bracket, the engaging portion engaged with the door main body can be configured to be fixed to the door main body by the fixing tool. Thereby, for example, after engaging the engaging portion with the door body and positioning the bracket, the bracket can be fixed to the door body by attaching the fixing tool to the engaging portion. Therefore, in this aspect, a fixing portion for attaching the fixing tool is not necessary.

In this case, for example, the engaging portion may have a male screw, and the fixture may have a female screw that is screwed into the male screw. That is, the bracket can be fixed to the door main body by attaching the male screw of the engaging portion to the door main body and screwing the female screw of the fixture to the male screw.

In any one of the brackets described above, the engagement portion can be disposed above the support portion in a state in which the bracket body is fixed to the door body by the fixture.

This configuration has the following advantages. The door main body, which can be selected to attach the window glass so that it can be raised or lowered, has a space formed so that the elevating mechanism can be attached to the inside of the door main body. In order to attach the window glass, the window glass is once stored in this space, and then lifted to fit the window glass into the window frame portion. Therefore, even when no lifting mechanism is provided, a similar attachment procedure is required from the viewpoint of component commonality. Therefore, even when the elevating mechanism is not provided, after the window glass is once accommodated in the door body, the bracket is fixed to the door body while being raised and fitted into the window frame portion. At this time, the bracket is often positioned visually from above the door body. Therefore, as described above, if the engaging portion is disposed above the support portion, the engaging portion can be easily seen and can be easily engaged with the engaged portion.

In any one of the brackets, the engaging portion is configured to engage with the engaged portion while moving in the first direction, and with the movement of the engaging portion in the first direction. The bracket body may be configured to rise with respect to the door body.

If comprised in this way, it can raise a window glass with attachment to the door main part of a bracket, for example, can make the upper edge of a window glass stick to the slot where the window glass of a door main body fits. it can.

There are various modes for such a mechanism. For example, the engaging portion is formed by a protrusion, the engaged portion is formed by a recess that engages with the protrusion, and the inner wall of the recess is The lower surface of the protrusion that contacts the lower portion may have an inclined surface that is inclined upward as it goes to the tip side of the protrusion along the first direction.

The glass module according to the present invention includes one or more brackets described in any one of the above and one vehicle window glass supported by the support portion.

The door structure according to the present invention includes one or more brackets according to any one of the above,

In the door structure, a functional film is formed on one surface of the vehicle window glass by a flow coat method, and the functional film is fixed to the door body by the fixture. The upper edge of the formed window glass can be accommodated inside the window frame or covered with a waterproof member.

This configuration has the following advantages. When the functional liquid is applied by the flow coating method, the film thickness of the functional film is the thickest in the vicinity of the upper edge of the window glass, and the thickness rapidly decreases below this, but becomes substantially constant. Therefore, there is a possibility that distortion of an image passing through the window glass may occur in a portion where the thickness changes abruptly. Therefore, as described above, if the upper edge of the window glass on which the functional film is formed is housed inside the window frame portion or covered with a waterproof member, the film thickness of the functional film changes abruptly. It is possible to prevent the region from being exposed to the outside. Thereby, it is possible to prevent image distortion.

A first method for fixing an automotive window glass according to the present invention is a method of fixing an automotive window glass to a door structure of a vehicle body with a fixture, wherein the automotive window glass is any one of the above-described ones. A step of fixing the bracket body to the door structure by engaging the engaging portion with the engaged portion; and a step of fixing the bracket main body to the door. And fixing to the main body with the fixing tool.

Moreover, the 2nd fixing method of the window glass for motor vehicles which concerns on this invention has an inner plate and an outer plate, has a space which can accommodate a window glass between the said inner plate and an outer plate, A method of fixing a window glass to the door body by a fixture so that the window glass cannot be lifted or lowered with respect to a door body that can be selected to be liftable or non-liftable. The bracket is positioned with respect to the door body by fixing the bracket to the support portion of any one of the brackets and engaging the engagement portion with the engaged portion formed on the inner plate. And a step of fixing the bracket body to the door body by the fixing tool.

In the fixing method, the support portion includes a base portion that supports a lower end surface of the automotive window glass, and a first sandwiching portion and a second sandwiching portion that extend upward from the base portion and sandwich the automotive window glass. And the first clamping part is fixed to the bracket body,
The second sandwiching portion is disposed to face the first sandwiching portion through a gap in which the automotive window glass is accommodated, and fixes the automotive window glass to the support portion of the bracket. In the step, an adhesive is injected between the first sandwiching portion and the second sandwiching portion, the automobile window glass is inserted between the first sandwiching portion and the second sandwiching portion, and the second sandwiching portion By visually confirming that the adhesive has protruded from the upper end of the vehicle, it is possible to confirm the completion of fixing the window glass for automobiles.

Here, when the height of the second sandwiching portion from the base portion is lower than the height of the first sandwiching portion from the base portion, the protruding amount of the adhesive is visually recognized while reducing the amount of the adhesive protruding. can do.

According to the present invention, when the window glass is fixed to the door structure so as not to move up and down, the accuracy of the window glass mounting position can be improved. Therefore, it can attach to a door structure in the same procedure as the case where the window glass for motor vehicles is attached so that raising / lowering is possible. As a result, it is possible to select whether the door structure is attached so that the window glass can be raised or lowered, and parts related to the attachment of the window glass can be made common.

In addition, after the door structure as described above is assembled, the gap between the window glass 4 and the side frame 31 and the upper frame 32, that is, the guide grooves of the side frame 31 and the upper frame 32, such as rain may enter. A glass run (not shown) for preventing or soundproofing is attached, and a weather strip (not shown) is attached to the gap between the window glass 4 and the inner plate 12 and the outer plate 11.

<2. Window glass>
Next, the window glass 4 will be described. As the window glass 4, a known glass plate used for automobiles can be used, and it can be formed of heat ray absorbing glass, general clear glass, green glass, or UV green glass. However, such a window glass needs to realize visible light transmittance in accordance with the safety standards of the country where the automobile is used. For example, the solar radiation absorptivity and visible light transmittance can be adjusted to satisfy safety standards. Below, an example of a composition of clear glass and an example of a heat ray absorption glass composition are shown.

(Clear glass)
SiO ₂ : 70 to 73% by mass
Al ₂ O ₃ : 0.6 to 2.4% by mass
CaO: 7 to 12% by mass
MgO: 1.0 to 4.5% by mass
R ₂ O: 13 to 15% by mass (R is an alkali metal)
Total iron oxide converted to Fe ₂ O ₃ (T-Fe ₂ O ₃ ): 0.08 to 0.14% by mass

(Heat ray absorbing glass)
The composition of the heat-absorbing glass, for example, based on the composition of the clear glass, the proportion of the total iron oxide in terms of _{_{Fe 2 O 3 (T-Fe}} 2 O 3) and 0.4 to 1.3 wt%, CeO The ratio of ₂ is 0 to 2% by mass, the ratio of TiO ₂ is 0 to 0.5% by mass, and the glass skeleton components (mainly SiO ₂ and Al ₂ O ₃ ) are T-Fe ₂ O ₃ , CeO. _The composition can be reduced by an increase of ₂ and TiO ₂ .

The thickness of the window glass 4 according to the present embodiment is not particularly limited, but is preferably 2.4 to 3.8 mm, more preferably 2.6 to 3.4 mm from the viewpoint of weight reduction. The thickness is particularly preferably 2.7 to 3.2 mm.

<3. Application of functional liquid to window glass>

A functional film is applied to the surface of the window glass 4. A functional film is a film formed from a functional liquid. The functional liquid is a liquid to which a functional material for giving a predetermined function to the glass plate 4 is added. As the functional liquid, for example, an ultraviolet cut coating liquid, an infrared (IR) cut coating liquid, an anti-fogging coating liquid, a water repellent coating liquid, an antifouling coating liquid, and a low one for giving the glass plate 4 a function of cutting ultraviolet rays. A reflective coating solution, an electromagnetic shielding coating solution, a colored coating solution, or the like is used. Of these, the water-repellent coating solution is applied to the surface of the window glass 4 on the vehicle outer side, and the others are applied to the vehicle inner surface.

The functional liquid as described above can be applied to the window glass by various methods. For example, it can be applied by a flow coating method. Hereinafter, regarding the flow coating method, a case where a functional liquid is applied to a rectangular window glass as shown in FIG. 3 will be described.

The window glass 4 in FIG. 3 has a first side 41 extending in the vertical direction on the right side, and has a second side 42 extending in the vertical direction as a left side facing the first side 41. Yes. And it has the upper side 43 extended in a substantially horizontal direction as a side which connects the upper ends of the 1st side edge 41 and the 2nd side edge 42. The first side 41, the second side 42, and the upper side 43 are accommodated in the guide groove of the window frame portion 3 described above.

<3.1 Functional liquid application device>
Next, a coating apparatus for applying a functional liquid to a glass plate will be described with reference to FIG. FIG. 4 is a side view schematically showing the coating apparatus.

The coating device 6 includes an injection unit 61 that injects a functional liquid, a robot arm 62 that moves while supporting the injection unit 61, and a blower unit (not shown) that blows air to the glass plate 4.

The injection unit 61 includes a nozzle 611 facing the direction of the glass plate 4 and a base 612 that supports the nozzle 611. The base 612 has a tube member 64 formed of rubber or the like that supplies a functional liquid. It is connected. The tube member 64 supplies the functional liquid delivered from a pump (not shown) that delivers the functional liquid to the injection unit 61. The nozzle 611 and the tube member 64 communicate with each other through the base 612, and the functional liquid supplied by the tube member 64 is ejected from the nozzle 611.

The robot arm 62 supports the injection unit 61 and can be moved three-dimensionally in the vertical and horizontal directions. Further, the blower unit is a unit that is configured by, for example, one or a plurality of fans and blows air to a portion where the functional liquid is injected.

<3.2 Application method of functional liquid>
Subsequently, a functional liquid coating method using the coating apparatus 6 will be described. First, the glass plate 4 to be applied with the functional liquid is placed, for example, in a standing state, and the first surface 401 on which the functional liquid is applied is disposed toward the nozzle 611. At this time, the second surface 402 of the glass plate 4 is inclined at an angle D from the vertical direction. Here, L in FIG. 3 indicates a locus of the functional liquid ejected from the nozzle 611, that is, a coating line. In the following process, the functional liquid is applied from the nozzle 611 to the glass plate 4 along the coating line L.

First, the robot arm 62 is driven, and the nozzle 611 of the ejection unit 61 is moved to a position where the functional liquid hits the application start region Ra when the functional liquid is ejected. When the functional liquid is ejected from the nozzle 611 to the application start region Ra, the nozzle 611 is moved upward. As a result, the functional liquid is applied along the first side 41. When the application position reaches the region Rb near the upper end of the first side 41, the nozzle 611 is moved in the horizontal direction. That is, the nozzle 611 is moved along the upper side 43. At this time, the functional liquid ejected along the upper side 43 flows down, whereby the functional liquid is applied onto the first surface 401 below the upper side 43. Therefore, it is possible to make the functional liquid go around even in a portion where the functional liquid is not directly injected, and the amount of the functional liquid used to apply the functional liquid to the glass plate 4 can be reduced.

When the nozzle 611 reaches the region Rc that is the end of the upper side 43, the nozzle 611 is moved downward and the functional liquid is applied along the second side side 42. Thus, when the application position of the functional liquid reaches the region Rd that is near the lower end of the second side edge 42, the injection of the functional liquid from the nozzle 611 is stopped. When applying such a functional liquid, air is blown onto the glass surface 401 by the blower unit, thereby drying the functional film formed on the glass surface 401.

By the way, it is confirmed that when the functional liquid is applied by the flow coating method as described above, the thickness of the functional film changes according to the distance from the application line L of the functional liquid along the upper side 43 of the glass plate 4. It was done. FIG. 5 is a graph showing an example thereof, and shows an example in which the glass plate 4 is supported at three types of angles D.

According to the figure, the film thickness of the functional film is the thickest in the vicinity of the coating line L (region Mb) on the upper side 43 at any angle, and the film thickness rapidly decreases when going downward. More specifically, the film thickness is large in the region within 0.5 to 1 mm downward from the coating line L, and when it is below this, the film thickness decreases rapidly, but the film thickness is substantially constant. This is because although the functional liquid flows downward due to gravity, the functional liquid remains in the vicinity of the upper side 43 due to the surface tension of the functional liquid and then solidifies. In such a place where the film thickness changes abruptly, when the image is viewed through the glass plate 4, the image may appear distorted.

Therefore, it is necessary to adjust the position of the coating line L on the upper side 43 of the glass plate 4 so that such a thick region is accommodated in the guide groove of the window frame portion 3 or covered with the glass run. is there.

<4. Bracket>
Next, the bracket 7 will be described with reference to FIGS. 6 and 7. 6 is a perspective view of the bracket, and FIG. 7 is a side view of FIG. As shown in FIGS. 6 and 7, the bracket 7 includes a bracket body 71 having a rectangular shape when viewed from the front, and a support portion 72 for the window glass 4 attached to the bracket body 71. The bracket body 71 is formed in a plate shape, and one surface forms an inner surface 711 that contacts the inner plate 12, and the other surface forms an outer surface 712 that faces the outer plate 11. A through hole 713 that passes between the inner side surface 711 and the outer side surface 712 is formed at the center of the upper portion of the bracket main body 71, and a screw that will be described later is screwed into the inner wall surface of the through hole 713. An internal thread is formed. Further, a protrusion 73 protruding from the inner surface 711 is formed on the side surface of the bracket main body 71 and engages with the engagement hole 51 formed in the inner plate 12 of the door structure described above.

Further, the support portion 72 is integrally attached to the lower end portion of the outer side surface 712 of the bracket body 71, and is formed in a U-shape in side view having a groove 720 extending in the vertical direction. More specifically, the support portion 72 includes a base portion 721 that supports the lower end portion of the window glass, and plate-like first and second holding

portions

722 and 2 that extend upward from the base portion 721 and sandwich the window glass 4. 723, and the first clamping portion 722 is integrally fixed to the bracket body 71. The support portion 72 is formed in a U-shape as a whole by the base portion 721 and the first and second holding

portions

722 and 723. Moreover, the groove | channel 720 formed between both the clamping

parts

722 and 723 is extended along the outer surface 712 of the bracket main body 71, and the lower end part of the window glass 4 mentioned above is engage | inserted. The lower end of the groove 720 is positioned below the through hole 713 and the protrusion 73. As shown in FIG. 7, a gap 75 is formed between the groove 720 and the outer surface 712 of the bracket body 71 in the thickness direction of the bracket body 71.

The material for forming the bracket 7 is not particularly limited, but can be formed of a resin material such as plastic.

<5. Window glass fixing method>
Then, the method to fix the window glass 4 mentioned above to a door structure is demonstrated. First, as shown in FIG. 8, brackets 7 are respectively attached to two positions on the lower edge of the window glass 4 described above. That is, the lower end edge of the window glass 4 is fitted into the groove 720 of the support portion 72 of the bracket 7 and fixed with an adhesive such as urethane adhesive. A glass module is formed by the window glass 4 and the bracket 7 assembled in this manner.

Next, the window glass 4 to which the bracket 7 is attached is fitted into the door structure. First, the window glass 4 is fitted into the space 13 between the inner plate 12 and the outer plate 11 and inserted below the space 13. As described above, since the upper end of the inner plate 12 is disposed slightly below the upper end of the outer plate 11, the window glass 4 is inserted into the space 13 using this gap. Then, when the window glass is inserted into the space 13 until the vicinity of the upper end of the window glass 4 is located in the vicinity of the upper edge 111 of the outer plate 11, subsequently, both sides of the window glass 4 are placed in the space 13. The

run channels

38 and 39 are engaged with each other. And the window glass 4 is pushed up so that the both

sides

41 and 42 of the window glass 4 may follow each

run channel

As described above, according to the present embodiment, since the projection 73 is provided on the bracket body 71, the projection 73 of the bracket body 71 is engaged with the door body 1 after the window glass 4 is supported by the support 72. If it engages with the joint hole 51, the positioning of the window glass 4 to the door body 1 can be performed. Thereafter, the bracket body 71 can be fixed to the door body 1 with screws. Therefore, even when the window glass 4 is fixed to the door body 1 so as not to be lifted and lowered, the window glass 4 can be fixed after being positioned with respect to the door body 1. In particular, the positional accuracy in the vertical direction can be improved.

<5. Modification>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. Note that the following modifications can be combined as appropriate.

<5.1>
The bracket can be variously changed. For example, the number of protrusions 73 is not limited to one, and a plurality of protrusions 73 may be provided. Moreover, although the protrusion 73 of the said embodiment is comprised so that it may insert in the engagement hole 52 formed in the inner board 12 of a door structure, for example, it opens to the upper end part of the inner board 12 upwards. It is also possible to form a notch 55 to be formed and to hook a protrusion with respect to the notch 55. In this case, it is preferable to form a locking piece facing downward at the tip of the protrusion so that the protrusion does not come off, and to form an L shape as a whole.

Here, FIG. 9 shows another example of the bracket according to the present invention. As shown in the figure, the bracket 9 is different from the bracket 7 according to the above embodiment in the form of the protrusion 73, and the bracket body, the support part and the like are the same form. On both sides of the bracket body 91 of the bracket 9, protrusions 93 having an L shape in side view are provided. Each protrusion 93 is engaged with a notch 55 formed at the upper end of the inner plate 12. With such a bracket 9, the protrusion 93 can be engaged with the notch 55 in the upper end portion of the inner plate 12 from above, so that the bracket 9 can be easily attached. Further, since the bracket 9 is engaged with the inner plate 12 at two points, the bracket 9 can be prevented from rotating with respect to the inner plate 12.

<5.2>
Further, when the glass module is fixed to the door structure, if the bracket 7 is configured as shown in FIG. 10, the upper edge of the window glass 4 can be securely adhered to the glass run. FIG. 10 is a front view (a) and a side view (b) showing another example of the bracket. As shown in the figure, the bracket 7 is different from the bracket shown in the above embodiment in the configuration of the protrusion 73. Specifically, a convex guide portion 731 along the direction in which the protrusion 73 extends is formed on the lower surface of the protrusion 73. An inclined surface 731 a is formed on the lower surface of the guide portion 731. The inclined surface 731 a is inclined upward toward the tip of the protrusion 73.

The glass module to which the bracket 7 is attached is attached to the door structure as shown in FIG. First, as shown to Fig.11 (a), the front-end | tip of the protrusion 73 is hooked in the engagement hole 51 of a door structure. At this time, the upper end portion of the window glass 4 enters the inside of the glass run 320. The glass run 320 is formed of an elastic material such as rubber, and has a base portion 321 extending in a long shape in the paper surface direction of FIG. 11 and a plate-like inner side that extends downward from both sides of the base portion 321 and sandwiches the window glass 4. A portion 322 and an outer portion 323 are provided and are integrally formed. In the initial state of attachment shown in FIG. 11A, a gap S is formed between the upper edge of the window glass 4 and the base 321 of the glass run 320.

Then, when the glass module is pushed into the inner plate 12 side (first direction X) from the state of FIG. 11A, the inclined surface 731 a of the protrusion 73 as the protrusion 73 enters the engagement hole 52. Rides on the inner wall surface of the engagement hole 51, and the bracket 7 is pushed upward as shown in FIG. 11 (b). Along with this, the window glass 4 is also pushed upward, so that the gap S between the upper edge of the window glass 4 and the base 321 of the glass run 320 is filled. That is, the upper edge of the window glass 4 and the base 321 of the glass run 320 are in close contact.

Thus, the window glass 4 and the glass run 320 can be reliably adhered by configuring the bracket 7 to move upward as the bracket 7 is attached to the inner plate 12. For example, when there is no such mechanism, the upper edge of the window glass 4 must be brought into close contact with the glass run 320 when the projection 73 of the bracket 7 is hooked in the engagement hole 51. However, according to the above configuration, strict dimensional accuracy is not necessary. Further, even if the upper edge of the window glass 4 is in close contact with the glass run 320, when the protrusion 73 enters the engagement hole 51, the frictional force between the upper edge of the window glass 4 and the glass run 320 There is also a problem that it is difficult for the protrusion 73 to enter the engagement hole 51. Therefore, according to the above configuration, these problems can be solved.

In addition, the structure for the bracket 7 to move upward as the bracket 7 is attached to the inner plate 12 is not limited to the above. For example, a protrusion is provided on the inner plate 12 instead of the engagement hole, and an engagement hole is provided on the bracket 7 instead of the protrusion. If the inclined surface is formed on the upper surface of the protrusion of the inner plate 12, the window glass 4 can be moved upward.

<5.3>
When attaching the window glass 4 to the bracket 7, there is a method of using an adhesive as described above. However, in order to confirm that the window glass 4 is securely attached, the following method can be used. it can. First, as shown in FIG. 12A, the adhesive 700 is injected into the groove 72 of the support portion 72 of the bracket 7, and the window glass 4 is inserted into the groove 700. As a result, the adhesive 700 is pushed out of the groove 720 by the window glass 4 and protrudes from the upper edges of the sandwiching

portions

722 and 723. At this time, the operator can confirm that the window glass 4 is correctly fitted in the groove 720 by visually recognizing that the adhesive protrudes from the upper edge of the second sandwiching portion 723. For example, if the adhesive 700 does not protrude from the upper edge of the second sandwiching portion 723, there is a possibility that foreign matter is in the groove 720 and the lower edge of the window glass 4 does not reach the base portion 721, or adhesion The amount of agent may be small. Therefore, when the window glass 4 is correctly attached, it is easy to check the attachment of the window glass 4 by adjusting the amount of the adhesive 700 so that the adhesive 700 slightly protrudes from the upper edge of the second sandwiching portion 723. Can be done.

Further, as shown in FIG. 13, the protrusion of the adhesive can be easily visually recognized by making the height of the second sandwiching portion 723 from the base portion 721 lower than the height of the first sandwiching portion 722 from the base portion 721. be able to. Thereby, the amount of the adhesive protruding for visual recognition can be reduced as compared with the example shown in FIG. In this case, it is necessary to determine the height of the second sandwiching portion 723 and the amount of adhesive in consideration of the adhesive strength between the sandwiching

portions

722 and 723 and the window glass 4.
