Description

  The present invention relates to a glass run mounting structure.

  Generally, a glass run is provided along the inner periphery of a door frame of an automobile. When viewed from the cross-sectional direction, the glass run includes a base portion and a vehicle body side wall portion extending from the base portion and a vehicle body side wall portion and a vehicle outer side wall portion. It has a car outer seal lip. In the glass run, the main body is attached to an attachment portion (for example, a channel portion) provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass are sandwiched between both seal lips. Sealed.

  In recent years, a glass run is composed of an extrusion molding part formed in a substantially linear shape and a mold forming part that connects the extrusion molding parts at a predetermined angle, for example, along the shape of a door frame. The front vertical side, the upper side, and the rear vertical side. That is, the mold forming part is provided corresponding to the corner part (see, for example, Patent Document 1).

  In addition, there is a technique in which a long run formed by extrusion is partially cut out and a corner shape is formed by bending the portion, and then a glass run is attached (for example, see Patent Document 2).

JP-A-6-219160 JP 2002-274187 A

  However, when the glass run is composed of the extrusion-molded portion and the mold-molded portion as in Patent Document 1, the connection line between the extrusion-molded portion and the mold-molded portion appears in the appearance, resulting in this. The appearance quality may be degraded. In addition, the composition material may be different between the extrusion molding part and the molding part, and the color and gloss of the surface are greatly different, and this difference in color and gloss leads to a decrease in appearance quality. There is a risk that. Furthermore, a step is likely to be formed at the boundary portion (connecting portion) between the extrusion-molded portion and the mold-molded portion, and the sealing performance may be deteriorated. In addition, since molding is required separately from extrusion molding, the manufacturing cost and manufacturing man-hour are increased accordingly.

  Further, even when a corner shape is formed by providing a notch (slit) partially as in Patent Document 2, processing for forming the corner shape is required. For this reason, the manufacturing cost and the manufacturing man-hour are increased accordingly.

  By the way, when the door glass is opened / closed (lifted / lowered), there is a concern that the opening / closing stress of the door glass acts on the glass run and the glass run is displaced in the longitudinal direction. In order to dispel such concerns, in general, in a glass run composed of an extrusion-molded portion and a mold-molded portion, for the purpose of preventing slippage, the mold-molded portion is locked in a hole or recess formed in the mounting portion. The protrusion is partially provided.

  However, when the entire length of the glass run in the longitudinal direction of the glass run is formed by an extrusion-molded body as in the above-mentioned Patent Document 2, it is extruded with the same cross-sectional shape. The part cannot be provided partially. That is, when it is intended to partially provide the protrusion for preventing the deviation, a step of partially providing the protrusion by mold forming after the extrusion molding is required. For this reason, a reduction in production efficiency is caused, and there is a possibility that the significance of configuring the entire longitudinal direction with the extrusion-molded body is diminished.

  The present invention has been made in view of the above circumstances, and an object thereof is to prevent the displacement movement caused by the stress at the time of opening and closing the door glass while improving the appearance quality and suppressing the decrease in the manufacturing efficiency. It is to provide a glass run mounting structure that can be used.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A body portion attached to a mounting portion provided along the inner periphery of the vehicle door frame, and having a substantially U-shaped cross section comprising a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion; A vehicle inner side seal lip and a vehicle outer side seal lip extending inward of the main body from the front ends of the vehicle inner side wall and the vehicle outer side wall,
Glass in which the entire longitudinal direction composed of the upper side corresponding to the upper edge of the door glass and the front vertical side and the rear vertical side corresponding to the front edge and rear edge of the door glass is constituted by an extruded product. In the mounting structure of the run,
At least one of the front vertical side portion and the rear vertical side portion is provided with an engaging portion formed by being partially cut away at a portion attached below the belt line,
The attachment portion is provided with an engaged portion that engages with the engagement portion in a glass run attached state,
A vehicle interior design lip extending from the substantial tip of the vehicle interior side wall portion to the vehicle interior side, and a vehicle exterior design lip extending from the substantial tip of the vehicle exterior side wall portion to the vehicle exterior side,
The glass run mounting structure, wherein the engaging portion is formed on at least one of the vehicle interior design lip and the vehicle exterior design lip.

  According to the means 1, the entire longitudinal direction of the glass run is constituted by the extruded product. Therefore, unlike the case where a glass run is formed by connecting a plurality of molded bodies including an extrusion molded body by molding, a situation in which a connection line appears on the appearance can be avoided. Further, it is possible to avoid a situation in which a difference in color / gloss occurs in the longitudinal direction (circumferential direction) of the glass run. As a result, the appearance quality is improved. Further, it is possible to avoid the possibility that a step due to connection is formed in the longitudinal direction of the glass run, and in this sense, the sealing performance is improved. Further, the manufacturing cost and the number of manufacturing steps can be reduced by the amount that does not require molding.

  Furthermore, since the corner portion is formed by being bent continuously without being provided with slits or notches, the manufacturing cost and the number of man-hours required for forming the corner portions such as notches are not required. Can be reduced.

  Further, when the engaging portion formed in the glass run is engaged with the engaged portion provided in the mounting portion, the displacement of the glass run in the longitudinal direction is restricted. Accordingly, it is possible to prevent a situation in which the glass run is displaced in the longitudinal direction when the door glass is opened and closed (lifted). Furthermore, the engaging portion and the engaged portion are provided below the belt line, that is, in a portion that is located in the door panel and does not appear in appearance. Therefore, it is possible to avoid a situation in which the appearance quality is deteriorated due to the visual recognition of the engaging portion and the engaged portion. In addition, for example, a separate molding step after extrusion, etc., as in the case where a protrusion for preventing displacement that is locked to a hole or a recess formed in the attachment portion is partially provided on the extrusion molded body, etc. Since it is not necessary to carry out the above, it is possible to suppress a decrease in manufacturing efficiency.

  Further, the engaging portion is notched in the design lip. For this reason, for example, it is possible to prevent a situation in which the function as a glass run (such as a decrease in sealing performance) is caused due to the formation of the engaging portion on the main body or the seal lip. Further, the notch work can be performed relatively easily. In addition, it is good also as forming the engaging part by notching a part of the said protruding part after extrusion forming by forming the protruding part protruding outward from a main-body part in the case of extrusion molding. Even in this case, the engaging portion can be formed without impairing the functions of the main body portion and the seal lip.

Mean 2. For the lower part of the mounting part below the belt line, a channel member having a substantially U-shaped cross section that fits the main body part inside, and a connecting part that connects the channel member and the door main body,
The vehicle that is press-contacted to the outer surface of the channel member by forming the connecting portion along the outer surface of the channel member toward the inner peripheral side of the glass opening that is opened and closed by the door glass. The glass run mounting structure according to claim 1, wherein the engaged portion that engages with the engaging portion formed on at least one of the inner design lip and the vehicle exterior design lip is formed.

  According to the means 2, the engaged portion can be formed relatively easily by partially changing the shape of the connecting portion for fixing the channel member to the door body. Therefore, it is possible to suppress a situation in which the production efficiency is reduced due to the formation of the engaged portion.

  In addition, regarding the portion above the belt line in the mounting portion, it has a channelless structure in which a channel member having a substantially U-shaped cross section is not mounted between the inner panel and the outer panel constituting the door frame, A glass run is good also as fitting between the front-end | tip parts of an inner panel and an outer panel. In this case, the cost can be reduced by the amount that the channel member need not be provided in the region above the belt line.

Means 3. For the lower part of the mounting part below the belt line, a channel member having a substantially U-shaped cross section that fits the main body part inside, and a connecting part that connects the channel member and the door main body,
By bending a part of the channel member, the channel member engages with the engagement portion formed on at least one of the vehicle interior design lip and the vehicle exterior design lip pressed against the outer surface of the channel member. The glass run mounting structure according to means 1, wherein the engaged portion is formed.

  According to the means 3, the engaged portion can be formed relatively easily by partially changing the shape of the channel member. Therefore, it is possible to suppress a situation in which the production efficiency is reduced due to the formation of the engaged portion.

Means 4. At the boundary part between the base part and the vehicle inner side wall part, and at the boundary part between the base part and the vehicle outer side wall part, a deformed connecting part thinner than other parts of the main body part is provided,
By attaching the glass run to the corner portion of the mounting portion, the deformation connecting portion of the glass run corresponding to the corner portion is inclined and deformed toward the inner peripheral side of the glass opening portion, and the base portion is made of glass. 4. The glass run mounting structure according to any one of means 1 to 3, wherein the glass run is displaced toward the inner periphery of the opening.

  According to the means 4, when the glass run is attached to the attachment portion, the base portion is displaced toward the inner peripheral side of the glass opening portion in the corner portion as compared with the other portion (straight portion). As a result, it is possible to smoothly and smoothly bend without forming a slit or the like in a portion corresponding to the corner portion of the glass run. Therefore, a situation in which the cross-sectional shape in the corner portion becomes extremely distorted due to the stress accompanying bending is avoided. As a result, the glass run can be easily and stably attached, and the function of the glass run can be fully exhibited. In addition, for example, in order to smoothly bend the glass run, it is not necessary to form a slit or notch in the body portion or the seal lip at the portion corresponding to the corner portion of the glass run. It is possible to prevent deterioration and deterioration of appearance quality.

(First embodiment; provided as a reference example)
The first embodiment will be described below with reference to the drawings. As shown in FIG. 1, a front door 3 (hereinafter simply referred to as a door) is provided in a door opening 2 of an automobile 1 as a vehicle so as to be opened and closed. The door 3 includes a door glass G that can be raised and lowered, and a glass run 4 that corresponds to the outer peripheral shape of the door glass G.

  As shown in FIG. 2, the glass run 4 extends downward from the upper edge 6, which is a portion corresponding to the upper edge of the door glass G, and the front edge of the upper edge 6, and corresponds to the front edge of the door glass G. A front vertical side portion 7 that is a portion and a rear vertical side portion 8 that extends downward from the rear end portion of the upper side portion 6 and that corresponds to the rear edge portion of the door glass G are provided. The glass run 4 in the present embodiment is made of EPDM (ethylene-propylene-diene copolymer) rubber, and the entire longitudinal direction composed of the front vertical side part 7, the upper side part 6 and the rear vertical side part 8 is formed by extrusion molding. In addition, corner portions C1 and C2 are formed by being continuously bent at two locations without being provided with slits or notches (this point will be described in detail later).

  As shown in FIGS. 3 and 4, the glass run 4 includes a main body 11, a vehicle exterior seal lip 12, and a vehicle interior seal lip 13. The main body 11 includes a base portion 14 fitted into a mounting portion constituted by the outer panel 3A and the inner panel 3B of the door 3, and an outer side wall portion 15 and an inner side wall portion that extend in a direction substantially orthogonal to the base portion 14. 16 and has a substantially U-shaped cross section as a whole. The vehicle outer side seal lip 12 extends from substantially the front end of the vehicle outer side wall portion 15 toward the inner peripheral side of the main body portion 11, and the vehicle inner side seal lip 13 extends from the substantially front end of the vehicle inner side wall portion 16 to the inner peripheral side of the main body portion 11. It extends toward. When the door glass G is closed, the vehicle outer side seal lip 12 is pressed against the outer side surface of the door glass G, and the vehicle inner side seal lip 13 is pressed against the inner side surface of the door glass G. Thereby, the vehicle exterior side and vehicle interior side of the door glass G are each sealed. In addition, an exterior design lip 17 extending from the exterior side wall 15 toward the exterior of the vehicle and an interior design lip 18 extending from the interior side wall 16 toward the interior of the vehicle are provided.

  Moreover, in this embodiment, since the whole longitudinal direction of the glass run 4 is formed as one continuous body only by extrusion molding, about any of the upper side part 6, the front vertical side part 7, and the rear vertical side part 8. Is also provided with a main body 11 and a pair of seal lips 12, 13 and the like, and has a similar cross-sectional shape. However, a channel portion 3C is provided between the outer panel 3A and the inner panel 3B in the lower portion of the front vertical side portion 7 and the rear vertical side portion 8 in the glass run 1, and the glass run is provided in the channel portion 3C. 4 is attached. Although not shown, a metal support portion (stopper) is provided corresponding to the upper portion of the upper side portion 6 so that the base portion 14 of the upper side portion 6 can come into contact with the support portion. Thereby, the stress at the time of the movement on the door glass G can be received.

  Next, a characteristic configuration in the present embodiment will be described.

  In the present embodiment, the base portion and the side wall portions are not directly connected, and the space between the base portion 14 and the vehicle outer side wall portion 15 and between the base portion 14 and the vehicle inner side wall portion 16 are not. These are connected by the deformation connecting portion 21. The deformable connecting portion 21 is thinner than the base portion 14 and the side wall portions 15 and 16 and has a substantially J-shaped cross section so as to have a predetermined length in the width direction. And under this structure, both corner parts C1, C2 of the glass run 4 are continuously bent without being provided with slits or notches. Here, as shown in FIG. 5, the deformed connecting portion 21 includes a fold portion (fold point BP in a cross-sectional view) in the vicinity of the end portion on the vehicle outer side wall portion 15 and the vehicle inner side wall portion 16 side, In both the corner portions C1 and C2, the deformation connecting portion 21 is deformed by bending at the folding portion (folding point BP). Thereby, in both corner part C1, C2, the base part 14 will be smoothly located in the inner peripheral side (lower side of a figure). That is, in both corner portions C1 and C2, the base portion 14 is located on the inner peripheral side compared to the other general portions, and the positioning is performed smoothly so that the cross-sectional shape is distorted. It is bent without becoming.

  Further, in the present embodiment, the guide lips 22, 23 that extend from the base portion 14 toward the side wall portions 15, 16 on the inner peripheral surface of the base portion 14, and whose tips are substantially in contact with the side wall portions 15, 16. Is provided.

  Further, water intrusion prevention lips 24 and 25 that can come into contact with the channel portion 3C are provided on the outer peripheral surface of the base portion 14. In this embodiment, the water intrusion prevention lips 24 and 25 form a pair, and the water intrusion prevention lip 24 on the vehicle outer side wall portion 15 side has a tip extending toward the vehicle outer side to prevent water intrusion on the vehicle inner side wall portion 16 side. The tip of the lip 25 extends toward the inside of the vehicle.

  In addition, in the present embodiment, the main body 11 including the guide lips 22 and 23 and the intrusion prevention lips 24 and 25 has a symmetrical shape with the center in the width direction as the center.

  According to the present embodiment configured as described above, the entire longitudinal direction of the glass run 4 composed of the upper side portion 6, the front vertical side portion 7, the rear vertical side portion 8, and both corner portions C1 and C2 is extruded. Therefore, unlike the case where the glass run is formed by connecting by mold forming, it is possible to avoid a situation in which the connection line appears on the appearance. In addition, it is possible to avoid a situation in which a difference in color / gloss partially occurs in the longitudinal direction (circumferential direction) of the glass run 4. As a result, the appearance quality can be improved. Further, it is possible to avoid the possibility that a step due to connection is formed in the longitudinal direction of the glass run 4, and in this sense, the sealing performance can be improved. Of course, it is possible to reduce the manufacturing cost and the number of manufacturing steps because the molding is not required.

  Furthermore, since the corner portions C1 and C2 are formed by being bent without being provided with slits or notches, the manufacturing cost and the number of man-hours for manufacturing the corner portions such as notches are not required. Can be reduced.

  On the other hand, since processing such as notches is not performed, there is a concern that the cross-sectional shape due to bending may be distorted. However, in the present embodiment, in the corner portions C1 and C2, other general portions are used. Compared to the portion, the base portion 14 is bent by being located on the inner peripheral side. More specifically, the section between the base portion 14 and the vehicle outer side wall portion 15 and between the base portion 14 and the vehicle inner side wall portion 16 is thin and has a substantially J-shaped cross section so as to have a predetermined length in the width direction. They are connected by a deformation connecting portion 21 having a shape. And in both corner part C1, C2, the deformation | transformation connection part 21 deform | transforms by bend | folding in the bending part (folding point BP) of the deformation | transformation connection part 21, Thereby, the base part 14 is smoothly inner peripheral side. To position. As a result, it is possible to smoothly bend without forming a notch or the like, and a situation in which the cross-sectional shape of the corner portions C1 and C2 becomes extremely distorted due to the stress accompanying the bending is avoided ( For example, even if the curvature radius is 60 mm, it can be bent without causing special irregular deformation). As a result, the glass run 4 can be easily and stably attached, and the function of the glass run 4 can be sufficiently exhibited.

  In particular, in the present embodiment, since the main body portion 11 has a symmetrical shape with the center in the width direction as the center, the base portion 14 is inclined when the base portion 14 is positioned on the inner peripheral side at both corner portions C1 and C2. The situation is unlikely to occur, and the base portion 14 can be smoothly positioned on the inner peripheral side while maintaining the angular relationship of the base portion 14 with respect to the side wall portions 15 and 16. As a result, it becomes easier to avoid a situation in which the cross-sectional shape becomes distorted in the corner portions C1 and C2.

  In the present embodiment, guide lips 22 and 23 are provided on the inner peripheral surface of the base portion 14. For this reason, when the base portion 14 is located on the inner peripheral side at the corner portions C1 and C2, as shown in FIG. 5, the guide lips 22 and 23 are guided by the side wall portions 15 and 16 (sometimes on both sides). The base portion 14 can be smoothly positioned on the inner peripheral side (while sliding along the wall surface). As a result, it is easier to avoid a situation in which the cross-sectional shape becomes distorted in the corner portions C1 and C2. In particular, the above effect can be further ensured by the symmetrical shape as in the present embodiment.

  Furthermore, since the water intrusion prevention lips 24 and 25 are provided on the outer peripheral surface of the base portion 14, it is possible to prevent a situation in which water enters the inside through the channel portion C3. In particular, the water intrusion prevention lips 24 and 25 are paired as described above and have a symmetrical shape as a whole. For this reason, not only can the water intrusion be prevented more reliably, but also a problem due to a mounting error can be prevented.

(Second Embodiment)
Hereinafter, a second embodiment will be described with reference to the drawings. FIG. 6 is a schematic front view showing a schematic configuration of the door. 7 is a cross-sectional view taken along line XX of FIG. 6 showing the upper side of the glass run. FIG. 8 is a cross-sectional view taken along line YY of FIG. 6 showing the glass run at the corner. FIG. 9 is a cross-sectional view taken along the line ZZ of FIG. 6 showing the rear vertical side portion of the glass run.

  As shown in FIG. 6, a front door 101 (hereinafter simply referred to as a door) that can be opened and closed at an opening for a car door corresponds to a door glass G that can be raised and lowered and an outer peripheral shape of the door glass G. And a glass run 105 that seals between the outer periphery of the door glass G and the door frame 102 when the door glass G rises and the glass opening W is closed. And are provided. The door 101 is provided with a glass weather strip (belt line molding 109) along the belt line.

  The glass run 105 extends downward from a front end portion of the upper side portion 106, which is a portion corresponding to the upper edge portion of the door glass G, and a front vertical side portion which is a portion corresponding to the front edge portion of the door glass G. 107 and a rear vertical side portion 108 that extends downward from the rear end portion of the upper side portion 106 and is a portion corresponding to the rear edge portion of the door glass G. The glass run 105 in this embodiment is made of EPDM (ethylene-propylene-diene copolymer) rubber, and the entire longitudinal direction composed of the front vertical side portion 107, the upper side portion 106, and the rear vertical side portion 108 is formed by extrusion molding. Yes. And the said glass run 105 is attached to the inner side of the attaching part 104 formed along the inner periphery of the door frame 102. FIG.

  As shown in FIG. 7, the upper side portion 106 of the glass run 105 includes a main body portion 111, a vehicle outer side seal lip 112, and a vehicle inner side seal lip 113. The main body portion 111 includes a base portion 114 fitted into the mounting portion 104, a vehicle outer side wall portion 115 and a vehicle inner side wall portion 116 extending in a direction substantially orthogonal to the base portion 114, and has a substantially U-shaped cross section as a whole. I am doing. The vehicle outer side seal lip 112 extends from substantially the front end of the vehicle outer side wall portion 115 toward the inside of the main body 111, and the vehicle inner side seal lip 113 extends from the substantially front end of the vehicle inner side wall portion 116 to the inside of the main body 111. It extends. When the door glass G is closed, the vehicle outer side seal lip 112 is pressed against the outer side surface of the door glass G, and the vehicle inner side seal lip 113 is pressed against the inner side surface of the door glass G. Thereby, the vehicle exterior side and vehicle interior side of the door glass G are each sealed. Further, an exterior design lip 117 that extends from the exterior side wall 115 toward the exterior of the vehicle and an interior design lip 118 that extends from the interior side wall 116 toward the interior of the vehicle are provided.

  In the present embodiment, since the entire longitudinal direction of the glass run 105 is formed as a single continuous body only by extrusion molding, any of the upper side portion 106, the front vertical side portion 107, and the rear vertical side portion 108 is used. The main body portion 111 and the pair of seal lips 112 and 113 are basically provided with the same cross-sectional shape.

  However, the mounting portion 104 is located above the belt line (belt line molding 109) and provided along the outer periphery of the glass opening W (hereinafter referred to as a sash portion DS), and more than the belt line. The cross-sectional shape is different from a portion (hereinafter referred to as a channel portion DC) that is located below and is provided in the door panel 103.

  As shown in FIGS. 7 and 8, the sash portion DS is formed by bending the ends of the outer panel 102 </ b> A and the inner panel 102 </ b> B constituting the door frame 102 to the inner peripheral side (lower side in FIG. 7) of the glass opening W. It is configured. In other words, the outer panel 102A is sandwiched between the vehicle exterior design lip 117 and the vehicle exterior side wall 115, and the inner panel 102B is sandwiched between the vehicle interior design lip 118 and the vehicle interior sidewall 116, so that the main body 111 is connected to the outer panel 102A and the inner panel 102A. The glass run 105 is attached to the sash portion DS by being fitted between the panel 102B.

  On the other hand, as shown in FIG. 9 and the like, the channel portion DC extends in the vertical direction along the longitudinal sides of the door glass G and has a substantially U-shaped cross section, and a predetermined portion of the channel member 103A. And a connecting portion 103B that connects the inner panel 102B. Then, the side wall portion of the channel member 103A is sandwiched between the vehicle exterior design lip 117 and the vehicle exterior side wall portion 115 and between the vehicle interior design lip 118 and the vehicle interior side wall portion 116. The glass run 105 is attached to the channel part DC by fitting the main body part 111 inside. Note that the connecting portion 103B is provided at two locations above and below the channel member 103A.

  As described above, with respect to the portion above the belt line (sash portion DS) in the mounting portion 104, a configuration in which no channel member is interposed between the outer panel 102A and the inner panel 102B (channel-less structure) reduces costs. In addition, weight reduction is achieved.

  In addition, the inner surface of the base portion 114 and the door glass sliding surfaces of the seal lips 112 and 113 are subjected to surface treatment so as to improve the sliding property of the door glass G. As the surface treatment, for example, a polyethylene (PE) tape or the like is attached to the inner side surface of the base 114 to form a sliding layer, or a coating film (for example, urethane coating) is applied to the surfaces of the seal lips 112 and 113. For example, it may be formed or planted on the surfaces of the seal lips 112 and 113.

  In the present embodiment, the deformation connecting portion 121 is formed at the boundary portion between the base portion 114 and the vehicle outer side wall portion 115 and at the boundary portion between the base portion 114 and the vehicle inner side wall portion 116. The deformation connecting portion 121 is thinner than the other portions (the base portion 114 and the side wall portions 115 and 116) of the main body portion 111. Further, the pair of left and right deformation connecting portions 121 extend obliquely in a direction approaching each other from the vehicle outer side wall portion 115 and the vehicle inner side wall portion 116 toward the outer peripheral side of the glass opening W (upward in FIGS. 7 and 8). Each tip is bent toward the inner peripheral side of the glass opening W (inside the main body 111), and has a substantially J-shaped cross section as a whole.

  When the glass run 105 is bent in accordance with the shape of the corner portion when the glass run 105 is attached to the attachment portion 104 (sash portion DS), as shown in FIG. Deforms to tilt inward. Thus, the base 114 is smoothly displaced from the position indicated by the two-dot chain line in FIG. 8 to the inner peripheral side (lower side in FIG. 8) of the glass opening W until the position indicated by the solid line in FIG. That is, in the corner portion, the base portion 114 is positioned on the inner peripheral side of the glass opening W compared to other portions (straight portions), and the positioning is performed smoothly, so that the cross-sectional shape It is bent without becoming distorted.

  Furthermore, on the inner side surface of the base portion 114, guide lips 122, 123 extending from the base portion 114 toward the side wall portions 115, 116 and having tips substantially in contact with the side wall portions 115, 116 are provided. When the base portion 114 is displaced toward the inner peripheral side of the glass opening W at both corner portions, the both guide lips 122 and 123 are guided by the side wall portions 115 and 116. This makes it easier to avoid a situation where the cross-sectional shape becomes distorted at the corner. In the present embodiment, the main body 111 including the deformed connecting portion 121 and the guide lips 122 and 123 has a symmetrical shape with the center in the width direction as the center. For this reason, when the base part 114 is displaced to the inner peripheral side of the glass opening W at the corner part, it is difficult for the base part 114 to be tilted, and the angular relationship of the base part 114 with respect to the side wall parts 115 and 116 is determined. The base 114 can be positioned on the inner peripheral side smoothly while keeping. As a result, it becomes easier to avoid a situation where the cross-sectional shape becomes distorted in the corner portion.

  Now, in this embodiment, the structure which prevents the position shift in the longitudinal direction of the glass run 105 is comprised below the belt line (belt line molding 109). Hereinafter, such a configuration will be described with reference to FIGS. FIG. 10 is a partial perspective view showing the glass run 105 (rear vertical side portion 108) attached to the channel portion DC.

  As shown in FIG. 10, the connecting portion 103B of the channel portion DC includes a back support portion 133 that is fixed to the back surface of the channel member 103A by spot welding, and extends from the back support portion 133 to the inside of the vehicle. On the other hand, a fixing portion 134 fixed by a fixing member such as a bolt or a rivet, and an insertion portion 135 protruding upward from the backrest portion 133 are provided. The insertion part 135 is inserted into a recess (not shown) formed in the door frame 102 above the belt line when the channel part DC is attached to the inner panel 102B. The insertion part 135 regulates the positional deviation in the rotation direction of the channel part DC.

  In the present embodiment, the back support part 133 includes a pair of engagement protrusions 137 extending toward the inner peripheral side of the glass opening W along both side surfaces of the channel member 103A. That is, the back pad 133 and the engaging protrusion 137 are formed in a substantially U-shaped cross section so as to surround the channel member 103A as a whole. Further, the engaging protrusion 137 extends to the inner peripheral side (the lower side in FIG. 9 and the right side in FIG. 10) of the glass opening W from the side wall portion of the channel member 103A, and the side wall of the channel member 103A. It is substantially in contact with the outer surface of the part. Since the fixing portion 134 of the connecting portion 103B is fixed to the inner panel 102B, the connection portion between the connecting portion 103B and the inner panel 102B is not exposed to the outside, and deterioration in appearance quality can be prevented. .

  On the other hand, the rear vertical side portion 108 is provided with an engagement concave portion 127 formed by cutting out the vehicle exterior design lip 117 and the vehicle interior design lip 118 at a portion corresponding to the engagement protrusion 137. Yes. When the glass run 105 (rear vertical side portion 108) is attached to the attachment portion 104 (channel portion DC), the engagement protrusion 137 is engaged with the engagement recess 127. More specifically, the design lips 117 and 118 of the rear vertical side portion 108 fitted into the channel member 103A are positioned outside the inner side surface of the engagement protrusion 137 in the vehicle width direction (left and right direction in FIG. 9). When viewed in the longitudinal direction (vertical direction), at least a part of the design lips 117, 118 overlaps with the engaging protrusion 137. For this reason, even when a displacement stress in the longitudinal direction acts on the glass run 105, the design lips 117 and 118 are engaged with the engagement protrusions 137 at the upper edge portion and the lower edge portion of the engagement recess 127. It abuts and the displacement movement in the longitudinal direction is restricted. In the present embodiment, the engaging recess 127 constitutes an engaging portion, and the engaging protrusion 137 constitutes the engaged portion.

  In this embodiment, when the glass run 105 is attached, there is a gap (for example, about 3 mm in the vertical direction) between the engaging protrusion 137 and the engaging recess 127 to allow manufacturing errors and assembly errors. ) Designed to be formed. Similarly to the rear vertical side portion 108, the front vertical side portion 107 is also provided with an engagement concave portion 127 formed by cutting out a portion corresponding to the engagement protrusion 137 of the connecting portion 103B. Therefore, the engaging recess 127 is engaged with the corresponding engaging protrusion 137.

  According to the present embodiment configured as described above, the entire longitudinal direction of the glass run 105 including the upper side portion 106, the front vertical side portion 107, and the rear vertical side portion 108 is formed by extrusion molding. Unlike the case where the glass run is configured by connecting the molded part and the molded part in the longitudinal direction, it is possible to avoid a situation in which the connection line appears on the appearance. In addition, it is possible to avoid a situation in which a difference in color / gloss occurs partially in the longitudinal direction (circumferential direction) of the glass run 105. As a result, the appearance quality can be improved. Further, it is possible to avoid the possibility that an unnecessary step due to the connection is formed in the longitudinal direction of the glass run 105, and in this sense, it is possible to improve the sealing performance. Furthermore, the number of man-hours required for manufacturing can be dramatically reduced, and as a result, manufacturing efficiency can be improved.

  Further, the engaging recess 127 formed in the glass run 105 is engaged with the engaging protrusion 137 provided in the channel portion DC (connecting portion 103B), so that the glass run 105 is displaced in the longitudinal direction. Be regulated. Therefore, when the door glass G is opened / closed (lifted / lowered), the glass run 105 can be prevented from being displaced in the longitudinal direction. Further, the engagement recess 127 and the engagement protrusion 137 are provided below the belt line (belt line molding 109), that is, in a portion that is located in the door panel 3 and does not appear in appearance. Therefore, it is possible to avoid a situation in which the appearance quality is deteriorated due to the visual recognition of the engaging recess 127 and the engaging protrusion 137. In addition, for example, a separate molding process is performed after extrusion, as in the case where a protrusion for preventing displacement is partially provided in the hole or recess formed in the mounting part on the extruded body. Since there is no need to do so, it is possible to suppress a decrease in manufacturing efficiency.

  The engaging recess 127 is formed in the design lips 117 and 118. For this reason, for example, it is possible to prevent a situation where the function as a glass run is deteriorated (decrease in sealing performance, etc.) due to the formation of the engaging recess 127 in the main body 111 or the seal lips 112, 113. can do.

  Furthermore, the engagement protrusion 137 that engages with the engagement recess 127 is relatively easy by partially changing the shape of the connecting portion 103B (back support portion 133) for fixing the channel member 103A to the inner panel 102B. Can be formed. Therefore, it is possible to suppress a situation in which the production efficiency is lowered due to the formation of the engaging protrusion 137.

  Further, according to the present embodiment, when the glass run 105 is attached to the attachment portion 104 (sash portion DS), the base portion 114 has the glass opening portion W in the corner portion as compared with other portions. Displaces to the inner circumference side. As a result, it is possible to smoothly and smoothly bend without forming a slit or the like in a portion corresponding to the corner portion of the glass run 105. Therefore, a situation in which the cross-sectional shape in the corner portion becomes extremely distorted due to the stress accompanying bending is avoided. As a result, the glass run 105 can be easily and stably mounted, and the function of the glass run can be fully exhibited. Moreover, according to this embodiment, since it is not necessary to form a slit, a notch, etc. with respect to the main-body part 111 or the seal lips 112 and 113, it is prevented reliably that a sealing performance fall and appearance quality fall are prevented. Can do.

Good. However, if the main body 111 itself (base 114 and both side walls 115 and 116) and the seal lips 112 and 113 are notched, the function as a glass run may be impaired. It is desirable to provide a notch in the other part. For example, at the time of extrusion molding, a protrusion protruding outward from the main body 111 (base 114) is formed, and after the extrusion, the protrusion is partially cut away in the longitudinal direction to engage the recess. It is good also as forming. Further, for example, a protrusion or lip that protrudes outward from the side wall portions 115 and 116, is pressed against the inner surface of the channel member 103A, or is locked to a knob-like portion formed on the inner peripheral side of the channel member 103A. (Slightly larger) may be provided, and an engaging recess may be formed on the protrusion or lip. Even when these configurations are employed, the engagement recess 127 can be formed without impairing the functions of the main body 111 and the seal lips 112 and 113. In addition, when employ | adopting the said structure, the engaging protrusion 137 is good also as forming by bending a part of channel member 103A inside.
