Description

  The present invention relates to a moving window for a vehicle including a window frame for a window plate that is slidable on the vehicle and a long guide strip that is mounted along the window frame and guides the sliding movement of the window plate. The present invention relates to a plate guide device.

  In general, the window frame provided on the door of the vehicle is inclined in accordance with the inclination of the front and rear pillars, and the front and rear window frame portions extending in a direction parallel to the vertical movement (sliding movement) direction of the window plate. It is composed of an inclined window frame part and an upper window frame part extending in a horizontal direction corresponding to the roof, and a long guide strip (glass run channel) is mounted along the inner peripheral edge of the window frame. This guide strip guides the window plate to move up and down.

  By the way, in the part mounted on the inclined window frame portion of the guide strip, when the window plate is closed and the upper end surface of the window plate hits the guide strip, the guide strip extends along the inclined window frame portion. Therefore, the guide strip may move obliquely upward and be displaced. Further, in the portion of the guide strip that is attached to the front window frame portion or the rear window frame portion, when the window plate moves up and down, the guide strip is caused by the frictional force generated between the window plate and the guide strip. The piece may move in the up-and-down movement direction of the window plate and be displaced.

As a countermeasure against such a positional deviation of the guide strip, as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-106825), in the portion of the base portion of the guide strip that comes into contact with the window frame, There is one in which an anti-slip member having a friction coefficient with respect to the window frame larger than that of the base portion is provided integrally.
JP 2004-106825 A (second page, etc.)

  However, as in the above-mentioned Patent Document 1, the configuration in which the slip prevention member having a large friction coefficient is simply provided at the base of the guide strip cannot sufficiently prevent the guide strip from being displaced with respect to the window frame. . In particular, when a lubricant such as an aqueous silicone resin solution is applied to the window frame or the guide strip for the purpose of improving the mounting workability when the guide strip is mounted on the window frame, the friction of the guide strip against the window frame. There is a problem that the effect of preventing the displacement of the guide strip relative to the window frame is further reduced due to the smaller coefficient.

  The present invention has been made in view of such circumstances, and the object of the present invention is therefore to provide a moving window plate guide device for a vehicle that can improve the effect of preventing the displacement of the guide strip relative to the window frame. Is to provide.

According to a first aspect of the present invention, there is provided a window frame made of a hard material having a substantially groove-shaped groove portion formed on the inner peripheral side for a window plate that is slidable on a vehicle, and along the groove-shaped portion of the window frame. A moving window plate guide device for a vehicle, comprising a long guide strip made of an elastic polymer material and mounted to guide the sliding movement of the window plate, wherein the window frame groove A misalignment preventing portion having at least one of a convex portion and a concave portion for preventing misalignment of the guide strip is provided on the inner surface of the guide portion, and the guide is provided along the groove-shaped portion of the window frame. When the strip is mounted, the misalignment prevention portion bites into the guide strip at the contact portion between the guide strip and the misalignment prevention portion, or the guide strip is uneven in the misalignment prevention portion. The guide strip is prevented from moving with respect to the window frame by being deformed according to the shape. Is configured so that, the displacement prevention portion, which has a substantially ribbon-like member having at least one of projections or recesses to be formed by securing to the inner surface of the groove portion of the window frame is there. Specifically, as described in claim 2 , the misalignment prevention portion is formed by fixing a substantially ribbon-shaped metal plate partially cut and raised to the inner surface of the groove portion of the window frame. It is good to do so. In this way, it is possible to provide a misregistration prevention portion in which a convex portion or a concave portion is formed by partial raising and punching (notch or through hole) applied to a substantially ribbon-shaped metal plate.

Further, as described in claim 3, the misregistration preventing portion may be formed by fixing a substantially ribbon-like net-like member to the inner surface of the groove-like portion of the window frame. If it does in this way, the position shift prevention part in which the convex part and the recessed part were formed with the substantially ribbon-shaped net-like member can be provided.

On the other hand, as in claim 4 , the guide strip may be provided with a soft portion made of a material softer than the main body portion of the guide strip at least in a portion in contact with the displacement prevention portion. . In this way, at the contact portion between the guide strip and the misalignment prevention portion, the misalignment prevention portion bites into the soft portion of the guide strip, or the soft portion of the guide strip becomes the uneven shape of the misalignment prevention portion. Therefore, the amount of biting in the misalignment prevention part and the deformation amount of the guide strip (soft part) must be sufficiently increased to make the contact part between the guide strip (soft part) and the misalignment prevention part stronger. Can be brought into a mechanically held state, and the effect of preventing the displacement of the guide strip relative to the window frame can be further improved.
In this case, as in claim 5 , the soft portion of the guide strip is preferably formed of any one material of foamed rubber, foamed resin, soft rubber, and soft thermoplastic elastomer.

According to a sixth aspect of the present invention, the soft portion of the guide strip is preferably made of a material having a higher coefficient of friction with respect to the inner surface of the groove-shaped portion of the window frame than the main body of the guide strip. If it does in this way, the frictional force which arises between a guide strip (soft part) and a window frame can be enlarged, and the position shift prevention effect of a guide strip with respect to a window frame can be improved further.

In addition, as in claim 7 , the main body portion and the soft portion of the guide strip are preferably integrated by heat fusion. If it does in this way, the main-body part and soft part of a guide strip can be firmly integrated by heat sealing | fusion.

  Hereinafter, the best mode for carrying out the present invention will be described using six Examples 1 to 6.

  The window frame 12 includes a front window frame portion 15 and a rear window frame portion 16 that extend in a direction substantially parallel to the moving direction of the window plate 14 and an upper window frame portion 17 that faces the upper end surface of the window plate 14. The upper window frame portion 17 is formed with an inclined portion 17a inclined corresponding to the inclination of the front pillar and a horizontal portion 17b extending substantially in the horizontal direction corresponding to the roof.

As the hard material forming the window frame 12, for example, a metal strip material such as a cold rolled steel plate (SPCC of JIS G3141) is used. Each of the front window frame portion 15 and the rear window frame portion 16 is a single straight line cut after being bent by a cold roll forming method so that the metal strip material has a predetermined cross-sectional shape (see FIG. 2). The straight window frame is bent in a predetermined direction (vehicle width direction) to bend, or is bent before the cutting following the bending process. In addition, the upper window frame portion 17 is formed by bending one straight window frame body in a predetermined direction (vertical direction and width direction of the vehicle) by a bending process using a bending process, thereby bending the inclined portion 17a and the horizontal portion 17b. It is integrally formed. And while the front side part of the upper side window frame part 17 and the upper end part of the front side window frame part 15 are joined by welding etc., the rear end part of the upper side window frame part 17 and the upper end part of the rear side window frame part 16 are connected.

As shown in FIG.

  As the elastic polymer material for forming the guide strip 13, for example, rubber, thermoplastic elastomer or the like is used. The front guide strip 19, the rear guide strip 20, and the upper guide strip 21 are each formed in a straight line during molding by extrusion molding or the like. Moreover, the front side corner part 22 and the rear side corner part 23 are formed in the shape bent according to the shape of the corner part of the window frame 12 by injection molding etc., respectively.

  In the state where the front end portion of the upper guide strip portion 21 and the upper end portion of the front guide strip portion 19 are set to intersect at a predetermined angle in the injection mold for molding the front corner portion 22, By injecting the elastic polymer material to form the front corner portion 22, the upper guide strip portion 21 and the front guide strip portion 19 are joined via the front corner portion 22. On the other hand, in the state where the rear end portion of the upper guide strip portion 21 and the upper end portion of the rear guide strip portion 20 are set to intersect at a predetermined angle in the injection mold for molding the rear corner portion 23, the injection is performed. By injecting an elastic polymer material into the mold and forming the rear corner portion 23, the upper guide strip portion 21 and the rear guide strip portion 20 are joined via the rear corner portion 23. .

Next, the specific structure of each window frame part 15-17 of the window frame 12 is demonstrated. The window frame portions 15 to 17 have substantially the same configuration and will be described with reference to a common drawing (FIG. 2).
As shown in FIG. 2, each window frame part 15-17 of the window frame 12 is a substantially groove | channel for mounting | wearing the guide strip 13 with an inner peripheral side by the bending process of metal strip materials, such as a cold rolled steel plate, for example. A groove-shaped portion 24 having a shape is formed along the longitudinal direction, and a door seal material holding portion 25 for holding a door seal material (not shown) on the outer peripheral side is formed along the longitudinal direction. A portion in which a plurality of metal strip members are folded at a substantially central portion in the width direction is fixed by spot welding or the like at a predetermined interval in the longitudinal direction.

  The groove-shaped portion 24 is formed by a side wall 26 on the vehicle inner side, a side wall 27 on the outer side of the vehicle, and a bottom wall 28 that connects both side walls 26, 27. Locking portions 34 and 35 for locking the guide strip 13 are formed on the front end side of the inner surface of 27. Further, at least the portion of the inner surface of the bottom wall 28 that contacts the guide strip 13 and the portion of the inner surface of each side wall 26 and 27 that contacts the guide strip 13 are displaced. The position shift prevention parts 29-31 for preventing this are provided continuously along the longitudinal direction.

  When the respective window frame portions 15 to 17 of the window frame 12 are molded, the respective misalignment prevention portions 29 to 31 are knurled on the inner surface of the groove-like portion 24 (the inner surface of the bottom wall 28 and the inner surfaces of the side walls 26 and 27). By processing, the inner surface of the groove-shaped portion 24 is plastically deformed, so that the inner surface of the groove-shaped portion 24 (the inner surface of the bottom wall 28 and the inner surfaces of the side walls 26, 27) is substantially V-shaped as shown in FIG. The groove 32 (recess) and the substantially V-shaped protrusion 33 (convex) extending along both sides thereof are formed directly on the inner surface of the groove-shaped portion 24. The height dimension of the ridge 33 of each of the position shift prevention portions 29 to 31 is set to a dimension smaller than the thickness dimension of the contact portion of the guide strip 13. Thereby, when the guide strip 13 is mounted on the groove-shaped portion 24 of the window frame 12, the contact portion between the misalignment preventing portions 29 to 31 provided on the groove-shaped portion 24 of the window frame 12 and the guide strip 13 is used. The protrusions 33 of the misregistration prevention parts 29 to 31 bite into the guide strips 13 or the guide strips 13 are deformed according to the uneven shape of the misregistration prevention parts 29 to 31, thereby The contact portions with the slip prevention portions 29 to 31 are engaged with each other and mechanically held.

  As shown in FIG. 2, the misalignment prevention portion 29 provided on the inner surface of the bottom wall 28 of the groove-like portion 24 includes a concave strip 32 and a convex strip 33 (in FIG. 2, the concave strip 32 and the convex strips 33 on both sides thereof. Is shown in a single line) is formed in a mesh shape extending in a plurality of directions intersecting the longitudinal direction of the window frame 12. Thus, both the longitudinal displacement and the lateral displacement of the guide strip 13 with respect to the window frame 12 are prevented.

  Further, the misregistration preventing portions 30 and 31 provided on the inner surfaces of the side walls 26 and 27 of the groove-shaped portion 24 are formed so that the concave stripes 32 and the convex stripes 33 extend in a direction perpendicular to the longitudinal direction of the window frame 12. Has been. Thereby, the direction (direction orthogonal to the longitudinal direction of the window frame 12) in which the concave stripes 32 and the convex stripes 33 of the misalignment prevention portions 30, 31 provided on the inner surfaces of the side walls 26, 27 of the groove-like portion 24 extend. The direction in which the guide strip 13 is mounted on the window frame 12 is made to substantially coincide with the window frame 12 so that the window strip 12 is not caught when the guide strip 13 is pushed into the window frame 12 and mounted. The longitudinal displacement of the guide strip 13 with respect to the frame 12 is prevented.

  Next, a specific configuration of each guide strip portion 19 to 21 of the guide strip 13 will be described. In addition, since each guide strip part 19-21 is substantially the same structure, it demonstrates using common drawing (FIG. 3).

  As shown in FIG. 3, the guide strip portions 19 to 21 of the guide strip 13 are made of elastic polymer material such as rubber or thermoplastic elastomer mainly composed of EPDM (for example, durometer hardness according to JIS K7215 is HDA 50 to 90). The hollow base portion 36 facing the end face of the window plate 14, the side wall portion 37 on the vehicle interior extending so as to rise from both ends in the width direction of the base portion 36, and the side wall on the vehicle exterior side. A vehicle-side seal lip 39 and a vehicle-side seal lip 40 which are formed in a folded shape so as to protrude from the front end side of each side wall portion 37, 38 toward the substantially central side in the width direction of the base portion 36, respectively. A vehicle-side shielding lip 41 and a vehicle-side shielding lip 42 projecting from the front end side of each side wall 37, 38 toward the opposite side of the seal lips 39, 40, respectively. A locking piece 43 and the engaging piece 44 of the exterior of the inner side projecting toward the root side toward the outside in the width direction of the base portion 36, respectively of each side wall portions 37 and 38 are integrally formed.

  Furthermore, the outer surface of the base portion 36, the outer surfaces of the side wall portions 37 and 38, and the tip portions of the locking pieces 43 and 44 (that is, the portions that come into contact with the misalignment prevention portions 29 to 31 of the window frame 12) are respectively provided. Soft material layers 45 to 49 (soft portions) are formed. The soft material layers 45 to 49 are softer than the main body portion (base portion 36, side wall portions 37, 38, etc.) of the guide strip 13 (for example, durometer hardness according to JIS K7215 is HDA 10 to 45) and the window frame 12 The friction coefficient with respect to the inner surface of the groove-shaped portion 24 is made of a material larger than that of the main body portion of the guide strip 13. The soft material layers 45 to 49 may be made of a material that is softer and has higher adhesion to the inner surface of the groove-like portion 24 of the window frame 12 than the main body portion of the guide strip 13.

  The soft material layers 45 to 49 are contact portions between the position shift prevention portions 29 to 31 of the window frame 12 and the guide strip 13, and the convex strips 33 of the position shift prevention portions 29 to 31 are the soft material of the guide strip 13. While serving to increase the amount of deformation when the amount of biting into the layers 45 to 49 and the soft material layers 45 to 49 of the guide strip 13 are deformed according to the concavo-convex shape of the misalignment prevention portions 29 to 31, It plays a role of increasing the frictional force generated between the window frame 12 and the guide strip 13.

  As a soft material having a large friction coefficient that forms the soft material layers 45 to 49, for example, foamed rubber or foamed resin is used, and as a soft and highly adhesive material that forms the soft material layers 45 to 49, For example, soft rubber or soft thermoplastic elastomer is used.

  Further, low friction material layers 50 to 52 (low friction portions) are formed on the inner surface of the base portion 36 and the surfaces of the seal lips 39 and 40 (that is, portions in contact with the window plate 14). The low friction material layers 50 to 52 are formed of a material whose friction coefficient with respect to the window plate 14 is smaller than that of the main body (base portion 36 or the like) of the guide strip 13, and the guide strip 13 is moved when the window plate 14 moves. And plays a role of reducing the frictional force (sliding resistance) generated between the window plate 14 and the window plate 14.

  Examples of the material having a low friction coefficient for forming the low friction material layers 50 to 52 include slip materials such as PP (polypropylene), high molecular weight PE (polyethylene) or ultrahigh molecular weight PE, silicone, PA (polyamide), fluorine, and the like. A thermoplastic elastomer containing at least one is used. When the base portion 36 and the seal lips 39, 40 are made of rubber, a urethane resin paint or the like is applied to the inner surface of the base portion 36 or the surfaces of the seal lips 39, 40, or melted with vulcanized rubber. The low friction material layers 50 to 52 may be formed by integrating a thermoplastic elastomer that can be worn into a tape shape.

  Further, adhesion preventing layers 53 and 54 for preventing the seal lips 39 and 40 from adhering to the sidewall portions 37 and 38 are formed on the inner surfaces of the sidewall portions 37 and 38, and the adhesion preventing layers 53 and 54 are formed. Is formed of the same material as the low friction material layers 50 to 52. Note that the adhesion preventing layers 53 and 54 may be formed on the back surfaces of the seal lips 39 and 40. In addition, the seal lips 39 and 40 adhere to the side walls 37 and 38 by roughening at least one of the inner surfaces of the side walls 37 and 38 and the back surfaces of the seal lips 39 and 40 (to form an uneven shape). This may be prevented.

  The soft material layers 45 to 49, the low friction material layers 50 to 52, and the adhesion preventing layers 53 and 54 are firmly fused and integrated with the main body portion of the guide strip 13 by coextrusion molding.

  As shown in FIGS. 4 to 6, the window frame 12 and the guide strip 13 configured as described above have a bottom wall 28 of the groove portion 24 of the window frame 12 when the window frame 12 is attached to the door 11. The inner surface is inclined so as to form an obtuse angle with respect to the plate surface of the window plate 14. Further, when the guide strip 13 is mounted along the groove-shaped portion 24 of the window frame 12, the guide strip 13 is respectively connected to the locking portion 34 on the vehicle inner side and the locking portion 35 on the vehicle outer side of the window frame 12. The guide strip 13 is prevented from coming off and held in the groove-like portion 24 of the window frame 12 by locking the locking piece 43 inside the vehicle and the locking piece 44 outside the vehicle. Further, the seal lip 39 on the vehicle interior side and the seal lip 40 on the vehicle exterior side of the guide strip 13 are in contact with the surface of the window plate 14, respectively, so that the window plate 14 is held and the window frame 12 and the window plate 14 It is designed to seal the gap.

  In the first embodiment, since the misalignment preventing portions 29 to 31 are provided on the inner surface of the groove-shaped portion 24 of the window frame 12 (the inner surface of the bottom wall 28 and the inner surfaces of the side walls 26 and 27), When the guide strip 13 is mounted on the groove-shaped portion 24, as shown in FIG. 7, at the contact portion between the position-shift preventing portions 29-31 of the groove-shaped portion 24 of the window frame 12 and the guide strip 13, The protruding strips 33 of the slip prevention portions 29 to 31 bite into the guide strip 13 or the guide strip 13 is deformed according to the concavo-convex shape of the misalignment prevention portions 29 to 31, thereby preventing the guide strip 13 and the positional shift. The contact portions with the portions 29 to 31 can be engaged with each other and mechanically held. Thereby, even when the lubricant is applied to the window frame 12 or the guide strip 13 before the guide strip 13 is mounted, the guide strip 13 is moved relative to the window frame 12 by the up-and-down movement of the window plate 14. It is possible to prevent the displacement of the guide strip 13 with respect to the window frame 12 effectively.

  As shown in FIGS. 4 and 5, in the upper window frame portion 17 of the window frame 12, the upper end surface of the window plate 14 is attached to the seal lips 39 and 40 of the guide strip 13 as the window plate 14 moves upward. When the seal lips 39 and 40 are pressed against each other, the seal lips 39 and 40 are elastically deformed in a direction away from each other. Further, as shown in FIG. 6, in the rear window frame portion 16 (or the front window frame portion 15) of the window frame 12, the side end surface of the window plate 14 moves along the guide strip 13 as the window plate 14 moves up and down. When the seal lips 39, 40 are pressed against the seal lips 39, 40, the seal lips 39, 40 are elastically deformed in directions away from each other. At that time, the low friction material layers 51 and 52 formed on the surfaces of the seal lips 39 and 40 reduce the frictional force (sliding resistance) generated between the window plate 14 and the seal lips 39 and 40, respectively. Each seal lip 39, 40 can be elastically deformed smoothly without being caught.

  When the side wall portions 37 and 38 of the guide strip 13 are strongly pressed against the side walls 26 and 27 of the window frame 12 by the elastic force of the seal lips 39 and 40 elastically deformed in this manner, The amount of biting when the protrusions 33 of the misalignment prevention portions 30 and 31 provided on the side walls 26 and 27 bite into the soft material layers 46 and 47 formed on the side wall portions 37 and 38 of the guide strip 13 and the guide strip The amount of deformation when the soft material layers 46 and 47 formed on the respective side wall portions 37 and 38 of the 13 are deformed according to the concavo-convex shape of the misalignment preventing portions 30 and 31 provided on the respective side walls 26 and 27 of the window frame 12 is reduced. growing. For this reason, the contact portions between the side wall portions 37 and 38 of the guide strip 13 and the side walls 26 and 27 of the window frame 12 can be more firmly engaged and mechanically held, and the window frame It is possible to increase the effect of preventing misalignment by the misalignment preventing portions 30 and 31 provided on the respective side walls 26 and 27 of the twelve. In addition, if a misalignment prevention portion is provided in a portion of the window frame 12 where the soft material layers 48 and 49 are in contact, the misalignment prevention effect can be further enhanced.

  Moreover, in the first embodiment, the concave stripes 32 and the convex stripes 33 of the misalignment prevention portions 30 and 31 provided on the side walls 26 and 27 of the window frame 12 extend in a direction orthogonal to the longitudinal direction of the window frame 12. The guide strip 13 is pushed in and attached to the window frame 12 in the direction in which the concave stripes 32 and the convex stripes 33 of the misalignment prevention portions 30 and 31 extend (the direction perpendicular to the longitudinal direction of the window frame 12). It is possible to prevent the displacement of the guide strip 13 in the longitudinal direction with respect to the window frame 12 without impairing the mounting workability when the guide strip 13 is mounted on the window frame 12 by substantially matching the direction.

  As shown in FIG. 5, in the upper window frame portion 17 of the window frame 12, when the window plate 14 rises to the closed position (uppermost position), the upper end surface of the window plate 14 is the hollow base of the guide strip 13. Since the hollow base portion 36 abuts against the portion 36 and elastically deforms, the impact sound when the window plate 14 abuts against the base portion 36 of the guide strip 13 and stops can be reduced.

  In this way, when the upper end surface of the window plate 14 abuts against the base portion 36 of the guide strip 13 and the base portion 36 of the guide strip 13 is strongly pressed against the bottom wall 28 of the window frame 12, the bottom wall of the window frame 12. 28, the amount of biting when the protrusion 33 of the misalignment prevention portion 29 provided in 28 bites into the soft material layer 45 formed on the base portion 36 of the guide strip 13, and the soft material formed on the base portion 36 of the guide strip 13. The amount of deformation when the layer 45 is deformed according to the uneven shape of the misalignment prevention portion 29 provided on the bottom wall 28 of the window frame 12 increases. For this reason, the contact portion between the base portion 36 of the guide strip 13 and the bottom wall 28 of the window frame 12 can be more firmly engaged and mechanically held, and the bottom wall 28 of the window frame 12 can be held. The effect of preventing misregistration by the misregistration preventing unit 29 provided in the above is enhanced.

  Moreover, in the first embodiment, the concave stripes 32 and the convex stripes 33 of the misalignment prevention portion 29 provided on the bottom wall 28 of the window frame 12 are formed in a net shape extending in a plurality of directions intersecting the longitudinal direction of the window frame 12. Both the positional deviation in the longitudinal direction and the positional deviation in the width direction of the guide strip 13 with respect to the window frame 12 can be prevented.

  In the inclined portion 17 a (see FIG. 1) of the upper window frame portion 17 of the window frame 12, when the window plate 14 is closed and the upper end surface of the window plate 14 hits the base portion 36 of the guide strip 13, the guide strip. The piece 13 is pressed obliquely upward along the inclined portion 17 a of the upper window frame portion 17, but provided on the misalignment prevention portion 29 provided on the bottom wall 28 of the window frame 12 and the side walls 26, 27 of the window frame 12. Due to the misalignment preventing effect of the misalignment preventing portions 30 and 31, the guide strip 13 can be prevented from being displaced in the longitudinal direction along the inclined portion 17 a of the upper window frame portion 17.

  Further, as shown in FIG. 5, in the window frame structure in which the inner surface of the bottom wall 28 of the window frame 12 is inclined so as to form an obtuse angle with respect to the plate surface of the window plate 14, the upper end surface of the window plate 14 is the guide strip 13. The guide strip 13 is pressed in an oblique direction (width direction) along the inner surface of the inclined bottom wall 28 of the window frame 12 when it hits the base portion 36 of the window frame 12, but provided on the bottom wall 28 of the window frame 12. Due to the position shift prevention effect of the position shift prevention unit 29, the guide strip 12 can be prevented from being shifted in the oblique direction along the inner surface of the inclined bottom wall 28.

  As shown in FIG. 6, generally, in the rear window frame portion 16 (or the front window frame portion 15) of the window frame 12, the side end surface of the window plate 14 slightly contacts the base portion 36 of the guide strip 13. Designed to keep position. However, in an actual vehicle, the window plate 14 is moved up and down with the side end surface of the window plate 14 being in strong contact with the base portion 36 of the guide strip 13 due to manufacturing variations and assembly errors of parts and the window plate lifting mechanism. The side end surface of the window plate 14 may come into strong contact with the base portion 36 of the guide strip 13 during the movement or up-and-down movement of the window plate 14, and at this time, the base portion of the window plate 14 and the guide strip 13. A force that moves the guide strip 13 in the up-and-down movement direction of the window plate 14 is generated by the frictional force generated between the window frame 14 and the misalignment prevention portion 29 provided on the bottom wall 28 of the window frame 12 and the window frame 12. Due to the misalignment prevention effect of the misalignment prevention portions 30 and 31 provided on the side walls 26 and 27, the guide strip 12 can be prevented from being misaligned in the up-and-down movement direction of the window plate 14.
