Description

  The present invention relates to a glass run mounting structure.

  Generally, a glass run is provided at the periphery of the glass opening of an automobile. The glass run is composed of an extrusion molded part formed in a substantially straight shape (long shape) and a mold forming part that connects the extruded parts with a predetermined angle, for example, a glass opening. It consists of a front vertical side part, an upper side part, and a rear vertical side part along the shape. Further, when viewed from the cross-sectional direction, the glass run is formed from a substantially U-shaped main body portion including a base portion and a pair of side wall portions extending from the base portion in the inner peripheral direction of the glass opening, and from substantially leading ends of the both side wall portions. A pair of seal lips extending inward of the main body. In the glass run, the main body is attached to the inner periphery of the sash provided along the glass opening, and the inside and outside of the door glass are sealed by the pair of seal lips.

  As materials constituting the glass run, ethylene-α-olefin non-conjugated diene copolymer (EPDM), olefin-based thermoplastic elastomer (TPO), and the like are known.

  In recent years, many of the sashes have an opposing surface that faces the base portion and gradually extends from the vehicle interior portion toward the vehicle exterior portion toward the outer peripheral side of the glass opening. With respect to such a sash, the main body is attached such that the inner and outer surfaces of the base portion are parallel to the opposing surface of the sash. For this reason, like the opposing surface of the sash, the inner surface of the base portion is an inclined surface that is gradually inclined toward the outer peripheral side of the glass opening portion from the vehicle interior portion toward the vehicle exterior portion.

  However, the end face of the door glass is generally in an arc shape with different curvature radii depending on the part, and the curvature radius at the top is larger than the curvature radius at the skirt (corner). That is, as described above, when the inner surface of the base portion is an inclined surface that is gradually inclined toward the outer peripheral side of the glass opening portion from the vehicle inner side portion toward the vehicle outer side portion, Of the end face of the door glass, the skirt part comes into contact. In this case, compared with the case where the top portion of the end surface of the door glass contacts the base portion, the contact area becomes small, and a large stress may be locally applied. As a result, the base portion may be worn at a fast pace.

In order to suppress such wear of the base portion, as shown in FIG. 5, a tape (PE tape) 55 made of polyethylene resin or the like harder than the base portion 54 is formed on the inner surface of the base portion 54 that is in sliding contact with the door glass DG. Is used to improve the durability of the glass run 51 (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-71649

  However, when the PE tape 55 is attached to the inner surface of the base portion 54 as described above, although the wear resistance is improved, there is a possibility that the rigidity is improved together and the flexibility is lowered. is there. On the other hand, it is conceivable to make the PE tape 55 thin, but in this case, there is a possibility that a predetermined durability cannot be ensured.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a glass run mounting structure capable of improving durability while ensuring flexibility.

  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 the means to respond | correspond as needed are added.

Means 1. A glass run having a base portion and a main body portion having a substantially U-shaped cross section consisting of a base portion and a pair of side wall portions extending from the base portion, and a pair of seal lips extending inward from the substantially leading ends of the both side wall portions;
A sash provided along the glass opening of the vehicle,
A glass run mounting structure in which the main body is attached to the inner periphery of the sash,
At least in the part corresponding to the vertical side of the door glass,
The facing surface of the sash that faces the base portion gradually extends toward the outer peripheral side of the glass opening from the vehicle inner portion toward the vehicle outer portion,
In the attached state of the main body, the outer surface of the base is substantially parallel to the opposing surface of the sash,
The inner surface of the contact portion, which is a portion set so as to be in sliding contact with the end surface of the door glass, of the base portion corresponding to the vertical side portion of the door glass is attached to the main body portion. The glass run mounting structure according to claim 1, wherein the glass run mounting structure is configured as a vertical surface that is perpendicular or substantially perpendicular to the inner and outer surfaces of the door glass.

  According to the first aspect, the inner surface of the contact portion that is set so as to be in sliding contact with the end surface of the door glass among the inner surface of the base portion is vertical (substantially perpendicular) to the inner and outer surfaces of the door glass. It has become. As a result, the door glass comes into contact with the inner surface of the base portion at a substantially right angle. For this reason, a top part will contact a base part among the end surfaces of a door glass. That is, the contact area of the end portion of the door glass having a smaller radius of curvature than the top portion of the end face of the door glass comes into contact with the base portion, thereby preventing a risk that a large stress acts locally. Can do. Accordingly, it is possible to suppress the fear that the base portion is worn at a fast pace, and it is possible to improve durability.

  In addition, since the door glass comes into contact with the inner surface of the base portion at a substantially right angle, when the door glass comes into contact with the base portion, the door glass is guided to the inner surface of the base portion to cause a displacement movement. Such a fear can be avoided. Therefore, it is possible to suppress the possibility that the sliding performance is deteriorated due to the door glass being extremely brought close to the seal lip, and the base portion is worn at a fast pace.

  Furthermore, according to this means, since durability can be improved without hardening the base, flexibility as a glass run can be ensured. Therefore, the possibility that the rigidity of the glass run becomes unnecessarily high and the workability of attaching the glass run is reduced can be suppressed.

  In addition, you may mix | blend the sliding component for improving slidability with the material which comprises a contact part, and may form a coating film (for example, urethane coating film etc.) at least on the inner surface of a contact part. Further, not only the base portion of the portion corresponding to the vertical side portion of the door glass but also the base portion of the portion corresponding to the upper side portion, the inner surface of the contact portion may be a vertical surface perpendicular to the inner and outer surfaces of the door glass.

The glass run mounting structure according to claim 1, wherein the glass run mounting structure is provided.

  According to the means 2, in the general portion of the inner surface of the base portion, the inner and outer surfaces are configured to be substantially parallel. For this reason, for example, by making the entire inner surface of the base portion a vertical surface perpendicular to the inner and outer surfaces of the door glass, the outer portion of the base portion becomes too thick, or the inner portion of the vehicle is The possibility of becoming too thin can be prevented. Therefore, durability can be improved while ensuring flexibility.

  According to the means 3, the shift movement of the door glass to the vehicle inner side can be restricted. Accordingly, it is possible to prevent deterioration of slidability and prevention of rattling of the door glass. Further, in the case where a sliding layer for improving the slidability is formed on the inner surface of the base portion, the movement of the door glass to the vehicle inner side is restricted by the vehicle inner side guide portion. Of these, it is no longer necessary to form a sliding layer at a position inside the vehicle relative to the vehicle inside guide portion. Therefore, the usage amount of the material constituting the sliding layer can be suppressed, and an increase in cost can be suppressed.

  Note that, at the boundary portion between the general portion and the contact portion, the stepped portion may be formed such that the general portion is located closer to the inner peripheral side of the glass opening than the contact portion. When adopting such a configuration, the movement of the door glass can be restricted by the stepped portion. That is, in this case, the step portion constitutes the vehicle interior guide portion. Further, the vehicle inner side guide portion (step portion) may not be provided at an angle close to the vertical, and may be configured by a relatively gentle tapered surface.

  Means 4. The vehicle inner side guide portion protrudes from the vehicle inner end edge of the vertical surface toward the inner peripheral side of the glass opening, and in the attached state of the main body portion, the front end portion thereof is the side wall on the vehicle inner side.

  According to the means 4, even if the vehicle inner side guide portion is subjected to stress from the door glass by causing the front end portion of the vehicle inner side guide portion to substantially contact with the side wall portion on the vehicle inner side, the vehicle Deformation of the inner guide portion is restricted. Therefore, the rigidity of the vehicle inner side guide portion can be increased, and the effect of the means 3 can be achieved more reliably. In addition, since the rigidity of the vehicle inner side guide portion is enhanced by the front end portion of the vehicle inner side guide portion being substantially in contact with the side wall portion on the vehicle inner side, the vehicle inner side guide portion is made from the door glass even if it is not so thick. Can sufficiently withstand the stress. For this reason, the rigidity of the vehicle inner side guide part can be enhanced while ensuring the flexibility as a glass run.

  Means 5. The glass run mounting structure according to means 3 or 4, wherein the vehicle interior guide portion is constituted by a sliding layer made of a material harder than a material constituting the base portion.

  According to the means 5, the sliding resistance of the vehicle inner side guide part can be suppressed by the vehicle inner side guide part being made of a sliding layer made of a material harder than the base part. In raising and lowering the door, it is possible to suppress the possibility that the slidability deteriorates due to the door glass coming into contact with the vehicle inner side guide portion. Further, the rigidity of the vehicle inner side guide portion can be increased, and the effect of the means 3 can be achieved more reliably.

  Means 6. 6. The glass run mounting structure according to any one of means 1 to 5, wherein a vehicle outer side guide portion for restricting movement of the door glass to the vehicle outer side is provided on an inner surface of the base portion.

  According to the means 6, the shift movement of the door glass to the outside of the vehicle can be restricted. Accordingly, it is possible to prevent deterioration of slidability and prevention of rattling of the door glass.

  Mean 7 The vehicle outer side guide portion protrudes from the vehicle outer edge of the vertical surface toward the inner peripheral side of the glass opening, and in the attached state of the main body portion, the front end portion thereof is the side wall on the vehicle outer side. The glass run mounting structure according to claim 6, wherein the glass run is substantially in contact with the portion.

  According to the means 7, even if the vehicle outer side guide portion is subjected to stress from the door glass by causing the distal end portion of the vehicle outer side guide portion to be substantially in contact with the side wall portion on the vehicle outer side, the vehicle Deformation of the outer guide portion is restricted. Therefore, the rigidity of the vehicle outer side guide portion can be increased, and the effect of the means 6 can be achieved more reliably.

  Further, in general, the door glass is brought closer to the outside of the sash by flash surface formation, and therefore, it is often impossible to secure a space for providing the outside guide portion outside the vertical plane. . In this respect, according to this means, the vehicle outer guide portion is made thinner by increasing the rigidity of the vehicle outer guide portion by bringing the distal end portion of the vehicle outer guide portion into a substantially abutting state with the side wall portion on the vehicle outer side. You can plan. Therefore, even if there is only a relatively small space, it is possible to provide a vehicle outer side guide portion that can sufficiently withstand the stress from the door glass.

  Means 8. The glass run mounting structure according to any one of means 1 to 7, wherein a sliding member that suppresses an increase in sliding resistance when the door glass is raised and lowered is provided on the inner surface of the base portion. .

  According to the means 8, slidability can be improved. In addition, as a sliding member which suppresses the increase in the sliding resistance at the time of raising / lowering of door glass, the tape material, urethane coating layer, etc. made from a polyethylene resin are mentioned, for example. In addition, when the vehicle inner side guide portion and the vehicle outer side guide portion described in the above means 3 and 6 are provided, the sliding movement of the door glass to the general portion is restricted. There is no need to provide a member. Therefore, it is good also as "the sliding member which suppresses the increase in the sliding resistance at the time of raising / lowering of door glass is provided at least in the said vertical surface among the inner surfaces of the said base part."

  Hereinafter, an embodiment will be described with reference to the drawings. FIG. 1 is a schematic front view showing a schematic configuration of a door. 2 is a cross-sectional view taken along the line JJ of FIG. 1 showing the configuration of the glass run.

  A glass run is attached corresponding to the outer periphery of the glass opening of the automobile door. More specifically, as shown in FIG. 1, the door DF is provided with a sash DS so as to follow the outer peripheral shape of the door DF, and the glass opening through which the door glass is moved up and down by the sash DS. Part W is partitioned. And the glass run 1 is attached to the inner periphery of the sash DS.

  First, a schematic configuration of the glass run 1 will be described. As shown in FIG. 1, the glass run 1 includes an extrusion molding portion 2 corresponding to the upper side portion in the longitudinal direction, extrusion molding portions 3 and 4 corresponding to the front and rear vertical side portions, and two extrusion molding portions 2 and 2. A distinction is made between mold forming parts 5 and 6 (parts with a dotted pattern in FIG. 1) connecting the end parts of 3 and 2 and 4. Each extrusion molding part 2-4 is formed in the shape of a straight line (long shape) with the extrusion molding machine which is not illustrated. The mold forming parts 5 and 6 are connected and molded by a mold apparatus (not shown) so that the two extruded parts 2, 3 and 2, 4 are connected to each other at a predetermined angle. The glass run 1 is composed of an ethylene-α-olefin non-conjugated diene copolymer (EPDM).

  As shown in FIG. 2, the extrusion molding portion 3 includes a main body portion 11 and a pair of seal lips 12 and 13. The main body 11 includes a base portion 14 fitted into the sash DS, a vehicle outer side wall portion 15 and a vehicle inner side wall portion 16 extending from the base portion 14. When the door glass DG is opened and closed, the end surface of the door glass DG is in sliding contact with the inner surface of the base portion 14. Further, the seal lips 12 and 13 extend from substantially the front ends of the side wall portions 15 and 16 toward the inside of the main body 11 (in the direction of the base portion 14), respectively. In the closed state of the glass opening W, the outer surface of the seal lip 12 (the surface on the inner peripheral side of the glass opening W) is pressed against the outer surface of the door glass DG, and the outer surface of the seal lip 13 is made of the door glass DG. It is pressed against the inner surface. Thereby, the vehicle exterior side and vehicle interior side of the door glass DG are each sealed. Further, in the present embodiment, the vehicle exterior design lip 17 that extends outward (vehicle exterior) from the vehicle exterior side wall 15 and the vehicle interior design lip that extends outward (vehicle interior) from the vehicle interior side wall 16. 18 is formed.

  Moreover, since the extrusion molding part 3 is the structure which presses and seals the seal lips 12 and 13 extended to the inner side of the main-body part 11 from the substantially front-end | tip of the both-side wall parts 15 and 16 to the door glass DG, The width is larger than the thickness of the door glass DG. Further, the projecting length of the seal lip 13 inside the vehicle is longer than that of the seal lip 12 outside the vehicle. As a result, the door glass DG is brought closer to the vehicle exterior side of the sash DS in the closed state, and a flash surface is achieved. The extrusion molding parts 2 and 4 and the mold molding parts 5 and 6 also include a main body part 11 and a pair of seal lips 12 and 13.

  Note that, in the sash DS, the facing surface 20 facing the base portion 14 of the glass run 1 gradually extends toward the outer peripheral side of the glass opening W from the vehicle inner portion toward the vehicle outer portion. And the main-body part 11 is attached to sash DS so that the outer surface (surface by the side of sash DS) of the base part 14 may be substantially parallel to the opposing surface 20 of sash DS. Thereby, stabilization of the attachment state of the main-body part 11 is achieved.

  Moreover, the end surface of the door glass DG has a substantially arc shape with different curvature radii depending on the part, and the curvature radius at the top is larger than the curvature radius at the bottom (near the boundary with the flat inner and outer surfaces of the door glass DG). Is also getting bigger. In addition, you may employ | adopt the structure which made the end surface of the door glass DG the flat surface, and made the R process only in the corner part.

  Now, in this embodiment, the base part 14 of the extrusion molding part 3 opposes the contact part 21 which is a site | part set so as to slidably contact with the end surface of the door glass DG, and the end surface of the door glass DG. The general portion 22 is a portion that is not set (a portion that is not set so as to be in sliding contact with the door glass DG). As described above, since the door glass DG is brought closer to the vehicle exterior side of the sash DS by the flash surface formation, the contact portion 21 is closer to the center portion of the base portion 14 in the width direction of the base portion 14. Is also slightly biased toward the outside of the vehicle.

  In the general portion 22, the inner surface and the outer surface of the base portion 14 are substantially parallel. That is, the inner surface of the general portion 22 is substantially parallel to the opposing surface 20 of the sash DS in the attached state of the main body portion 11, and the glass opening W is directed from the vehicle inner side portion to the vehicle outer side portion. It becomes the inclined surface which inclines toward the outer peripheral side. In other words, the inner surface of the general portion 22 intersects the normal direction (the vertical direction in FIG. 2) of the inner and outer surfaces of the door glass DG.

  On the other hand, the inner surface of the contact portion 21 is configured as a vertical surface 23 that is substantially perpendicular to the inner and outer surfaces of the door glass DG when the main body portion 11 is attached. That is, the door glass DG is in sliding contact with the inner surface (vertical surface 23) of the base portion 14 at a substantially right angle.

  Further, in the present embodiment, the step portion 25 is formed along the boundary portion between the contact portion 21 and the general portion 22 so that the general portion 22 is positioned on the inner peripheral side of the glass opening W with respect to the contact portion 21. Has been. In the present embodiment, the step portion 25 constitutes a vehicle inner side guide portion. In addition, in the front-rear width direction (left-right direction in FIG. 2) of the door glass DG, the height difference of the step portion 25 is substantially the same as the protruding length of the end surface (substantially arcuate portion) of the door glass DG. . Note that the stepped portion 25 does not have to be formed at an angle close to vertical, and may be formed by a relatively gentle tapered surface.

  In the present embodiment, in the width direction of the base portion 14, the length of the contact portion 21 is 2/3 or less of the length of the inner surface of the base portion 14. Further, a urethane coating film (not shown) as a sliding member is formed on the inner surface of the base portion 14 to improve the slidability. In addition, the extrusion molding part 4 which comprises a back vertical side part is also provided with the contact part 21 which has the vertical surface 23 in the base part 14 similarly to the extrusion molding part 3. FIG.

  As described in detail above, in the present embodiment, the inner surface of the contact portion 21 set so as to be in sliding contact with the end surface of the door glass DG among the inner surface of the base portion 14 is the inner and outer surfaces of the door glass DG. On the other hand, the vertical surface 23 is substantially vertical. As a result, the door glass DG is in sliding contact with the inner surface of the base portion 14 at a substantially right angle. Therefore, for example, the inner surface of the contact portion 21 is an inclined surface that is gradually inclined toward the outer peripheral side of the glass opening W from the inner side of the vehicle toward the outer side of the vehicle. It is possible to suppress the risk of slipping on the outside of the vehicle and causing the vehicle to slip on the inner surface of the vehicle. Therefore, the sliding performance is deteriorated due to the door glass DG being brought to the seal lip 12 on the outside of the vehicle, or the outer periphery of the glass opening W when the surface of the base portion 14 is in sliding contact with the door glass. It is possible to suppress the fear that the base portion 14 is worn at a fast pace due to receiving stress toward the outside of the vehicle as well as stress toward the direction.

  Further, since the door glass DG abuts at an almost right angle to the inner surface of the base portion 14, the top portion of the end surface of the door glass DG comes into contact with the base portion 14. Therefore, compared with the case where the skirt portion of the end surface of the door glass DG is in contact with the base portion 14, the contact area can be increased, and a large stress may be locally applied to the base portion 14. Can be suppressed. For this reason, the possibility that the base portion 14 is worn at a fast pace can be suppressed, and as a result, durability can be improved.

  Furthermore, according to this embodiment, since durability can be improved without hardening the base part 14, the flexibility as a glass run can be ensured. Therefore, the possibility that the rigidity of the glass run 1 becomes excessively high and the workability of attaching the glass run 1 is lowered can be suppressed.

  Further, according to the present embodiment, the inner surface of the general portion 22 among the inner surfaces of the base portion 14 is substantially parallel to the facing surface 20 of the sash DS when the main body portion 11 is attached. For this reason, for example, by making the entire inner surface of the base portion 14 a vertical surface perpendicular to the inner and outer surfaces of the door glass DG, the vehicle outer portion of the base portion 14 becomes too thick, or the base portion It is possible to prevent a fear that the inner part of the vehicle 14 becomes too thin. Accordingly, durability can be improved while ensuring flexibility as a glass run.

  In addition, a step portion 25 is provided on the inner surface of the base portion 14 along a boundary portion between the contact portion 21 and the general portion 22. Due to the presence of the stepped portion 25, it is possible to prevent the door glass DG in contact with the base portion 14 (vertical surface 23) from shifting to the vehicle interior side. Accordingly, it is possible to prevent deterioration of slidability and prevention of rattling of the door glass DG.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the said embodiment, although the vehicle inside guide part for controlling the movement to the vehicle inside of the door glass DG is comprised by the level | step-difference part 25, it is not limited to such a structure in particular. For example, as shown in FIG. 3, it protrudes toward the inner peripheral side of the glass opening W from the inner edge of the vertical surface 23, and in the attached state of the main body 11, its tip is the inner side wall. The vehicle interior guide portion may be configured by the protruding portion 31 that is substantially in contact with the portion 16.

  When such a configuration is adopted, the protrusion 31 receives stress from the door glass DG because the tip end portion of the protrusion 31 serving as the vehicle inner side guide portion is substantially in contact with the vehicle inner side wall portion 16. Even in this case, the deformation of the protrusion 31 is restricted. Therefore, the rigidity of the protrusion 31 can be increased, and the shift movement of the door glass DG to the vehicle inner side can be more reliably regulated. Furthermore, since the rigidity of the projection 31 is enhanced by the tip end portion of the projection 31 being substantially in contact with the vehicle interior side wall 16, the stress from the door glass DG is not required even if the projection 31 is so thick. Can withstand enough. For this reason, the rigidity of the vehicle inner side guide part can be enhanced while ensuring the flexibility as a glass run.

  In general, the extrusion molding portion 3 is formed by extrusion in a shape in which the pair of side wall portions 15 and 16 are expanded from the base portion 14 into a substantially C-shaped cross section. And the main-body part 11 will be attached to the sash DS in the state which brought the side wall parts 15 and 16 so that it might become substantially parallel. However, in the case of adopting a configuration that increases the rigidity of the vehicle inner side guide portion by configuring the base portion 14 to be thick, including the connecting portion between the base portion 14 and the vehicle inner side wall portion 16, the base portion 14 is used. When the connecting portion between the vehicle and the vehicle interior side wall portion 16 is thick, it may be difficult to bend the vehicle interior side wall portion 16 inward at the connection portion. In this regard, when the above-described configuration is adopted, a gap can be formed between the protrusion 31 and the vehicle interior side wall portion 16, and the connecting portion between the base portion 14 and the vehicle interior side wall portion 16 is made thick. Since it is not necessary, the rigidity of the protrusion 31 can be increased while preventing the above problems. However, in the shape in which the pair of side wall portions 15 and 16 are expanded from the base portion 14 so as to have a substantially C-shaped cross section, the tip end portion of the projection portion 31 is separated from the vehicle interior side wall portion 16, and the main body portion 11 is removed. For the first time at the time of wearing, the tip end portion of the protruding portion 31 is brought into a substantially contact state with the vehicle interior side wall portion 16.

  In addition, it is good also as omitting the level | step-difference part 25 (vehicle inside guide part) which can control the movement to the vehicle inner side of the door glass DG.

  (B) Moreover, you may provide the vehicle outer side guide part which controls the movement to the vehicle outer side of the door glass DG with respect to the inner surface of the base part 14. FIG. In this case, the displacement movement of the door glass DG to the outside of the vehicle can be restricted. As an example, the general portion 22 is also formed on the vehicle exterior side of the contact portion 21, and the general portion 22 is positioned on the inner peripheral side of the glass opening W with respect to the contact portion 21 as in the above embodiment. Thus, a configuration in which a stepped portion as the vehicle outer side guide portion is formed may be mentioned.

  In general, the door glass DG is brought closer to the vehicle exterior side of the sash DS due to flash surface formation, and therefore, a space for providing the vehicle exterior guide portion can hardly be secured on the vehicle exterior side than the vertical surface 23. There are many cases. On the other hand, for example, as shown in FIG. 4, the vertical surface 21 protrudes from the outer edge of the vehicle 21 toward the inner peripheral side of the glass opening W. The projecting portion 33 serving as the vehicle outer side guide portion that is substantially in contact with the vehicle outer side wall portion 15 is provided. In this case, the rigidity of the projecting portion 33 is increased by bringing the tip end portion of the projecting portion 33 (vehicle outer side guide portion) into a substantially abutting state with the vehicle outer side wall portion 15. Thereby, thickness reduction of the protrusion part 33 (vehicle outer side guide part) can be achieved. Therefore, even if there is only a relatively small space, it is possible to provide a vehicle outer side guide portion that can sufficiently withstand the stress from the door glass DG.

  (C) In the above embodiment, a urethane coating film is formed on the inner surface of the base portion 14 as a sliding member that suppresses an increase in sliding resistance when the door glass DG is raised and lowered. It is not limited to. For example, you may comprise a sliding member by sticking the tape (PE tape) which consists of a raw material harder than the base part 14 so that the inner surface of the base part 14 of the extrusion molding part 3 may be covered.

  Even in the case of sticking the PE tape in this way, as described in the above embodiment, the durability of the glass run 1 can be improved by setting the inner surface of the contact portion 21 to the vertical surface 23. The PE tape does not need to be durable, and the PE tape can be made thin. Further, since the movement of the door glass DG to the inside of the vehicle is regulated by the step portion 25, a PE tape is attached to a portion of the base portion 14 that is inside the vehicle (the inner surface of the general portion 22) from the step portion 25. There is no need. Therefore, the usage-amount of the polyethylene resin which comprises PE tape can be suppressed, and the increase in cost can be suppressed.

  Further, for example, a sliding component for improving the slidability may be added to the material constituting the contact portion 21. In this case, in order to improve slidability, the operation | work which forms a coating film separately on the inner surface of the base part 14, or affixes PE tape can also be abbreviate | omitted.

  (D) The step portion 25 (near the boundary portion between the contact portion 21 and the general portion 22) as the vehicle inner side guide portion in the above embodiment is made of a material harder than the material constituting the base portion 14 (for example, polyethylene resin, You may comprise by the sliding layer which consists of TPO etc.). Moreover, when employ | adopting the structure of said (a), you may comprise the projection part 31 by the sliding layer which consists of a material harder than the material which comprises the base part 14. FIG. Thus, since the vehicle inner side guide part is comprised by the sliding layer which consists of a hard material, the sliding resistance of the said vehicle inner side guide part can be suppressed. Therefore, when raising / lowering the door glass DG, this door It is possible to suppress the risk that the slidability deteriorates when the glass DG comes into contact with the vehicle inner side guide portion. Further, the rigidity of the vehicle inner side guide portion can be increased, and the effect of restricting the displacement movement of the door glass DG to the vehicle inner side is more reliably achieved.
