Description

Technical Field

[0001] The present invention relates to a glass run channel for an automobile door which is arranged on a window frame of an automobile door. Background Art

[0002] As a door provided at the side of a vehicle, there is a door having a window frame for holding the periphery of a window glass, and a glass run channel for sealing a gap between the window frame and the window glass (see, for example, Patent Documents 1 and 2).

[0003] The glass run channel of Patent Document 1 includes a glass run channel main body extending in the vehicle front-rear direction along the upper side of the window frame. A molding made of a metal plate such as stainless steel or aluminum is provided on the vehicle outer side of the glass run channel main body.

[0009] Patent Document 2: Japanese Patent Publication No. 2022-111983 Summary of the invention

[0010] Technical problem to be solved by the invention

[0011] When the molding is made of, for example, a stainless steel plate as in Patent Document 1, there are problems in that the molding is heavy and the cost of the molding is high, which in turn increases the weight and cost of the glass run channel for an automobile door.

[0012] Patent Document 1 discloses a structure in which a resin component and a molding are formed integrally. This structure has the following problems: not only is the weight high, but the number of components increases, which further increases the cost. In addition, it takes a lot of time and effort to attach the resin component to the molding.

[0013] On the other hand, when a decorative strip is provided on the vehicle outer side of the glass run channel body as in Patent Document 2, the glass run channel body and the decorative strip cannot be separated. Therefore, when extruding a glass run channel body having a complex shape and high difficulty, if poor forming occurs on the glass run channel body, even if there is no problem with the decorative strip itself, the glass run channel must be discarded together with the decorative strip, which is not economical. Alternatively, when the type of the decorative strip is to be changed from a metallic tone to, for example, black, a glass run channel including a glass run channel body and having a new decorative strip must be produced. As described above, the extrusion molding of the glass run channel body is difficult. Therefore, it is not desirable to extrude the glass run channel body together with the decorative strip every time the type of the decorative strip is changed.

[0014] The present disclosure is made to solve the above technical problems, and its purpose is to provide a glass run channel for automobile doors which is light in weight, has a small number of parts, and can reduce costs.

[0015] Technical solutions for solving technical problems

[0016] In order to achieve the above-mentioned object, in a first aspect of the present disclosure, a glass run channel for an automobile door is provided as a premise, which is mounted on a window frame of an automobile door from the vehicle outer side and seals the window frame and the window glass. The glass run channel for an automobile door includes a glass run channel main body and a molding, wherein the glass run channel main body is mounted on a glass run channel mounting plate portion, wherein the glass run channel mounting plate portion extends from the upper portion of the window frame toward the vehicle outer side, wherein the molding is mounted on the vehicle outer side of the glass run channel main body and extends in the vehicle front-rear direction, wherein the molding includes a molding main body and a decorative strip, wherein the molding main body is a resin main body formed by extrusion, and wherein the decorative strip is co-extruded on the vehicle outer side of the molding main body.

[0017] According to this structure, for example, when the decorative strip is metallic, a molding having a metallic color on the vehicle exterior can be obtained without providing a stainless steel plate or an aluminum plate. When it is desired to change to black, the decorative strip of the molding, which is relatively easy to extrusion-form, can be changed to black, and the glass run channel main body can continue to be used. In addition, the resin and the decorative strip constituting the molding main body are lighter than the stainless steel plate or aluminum plate used as the material of the conventional metal molding, and the decorative strip is thinner than the stainless steel plate or aluminum plate, so the weight of the molding can be reduced. In addition, since the decorative strip is co-extruded when the molding main body is extruded, the molding main body and the decorative strip are one component when the molding is just manufactured, and the number of components does not increase.

[0018] In the second aspect of the present disclosure, the glass run channel body may be curved in an upward convex manner. In this case, an upper protrusion and a lower protrusion are formed at the upper end and the lower end of the molding body, respectively, the upper protrusion and the lower protrusion protrude toward the vehicle interior and extend in the vehicle front-rear direction, and the wall thickness of the lower protrusion can be set to be thicker than the wall thickness of the upper protrusion.

[0019] That is, the window frame is bent in an upward convex manner along the shape of the roof of the car, and therefore the glass run channel body is also bent in an upward convex manner. Therefore, it is preferable that the molding is also bent in an upward convex manner corresponding to the shape of the glass run channel body. According to this structure, since the wall thickness of the lower protrusion is thicker than that of the upper protrusion, the resin of the lower protrusion shrinks more during the cooling process of the resin after extrusion molding, and thus the molding is naturally bent in an upward convex manner.

[0020] In the third aspect of the present disclosure, the upper portion of the decorative band may also extend to reach the upper surface of the upper protrusion, and the lower portion of the decorative band may also extend to reach the lower surface of the lower protrusion.

[0021] According to this structure, the upper part of the decorative band surrounds the upper surface of the upper protrusion of the molding body, so the upper end of the decorative band is not easily visible from the outside, which is beautiful.

[0022] In a fourth aspect of the present disclosure, an upper protrusion and a lower protrusion may be formed at a portion of the glass run channel body where the molding body is mounted, the upper protrusion protruding upward and extending in the vehicle front-rear direction, and the lower protrusion protruding downward and extending in the vehicle front-rear direction. In this case, an upper fitting portion fitted with the upper protrusion and a lower fitting portion fitted with the lower protrusion are formed on the vehicle interior side of the molding body, and the molding can move relative to the glass run channel body in the vehicle front-rear direction when the upper fitting portion and the lower fitting portion are respectively fitted with the upper protrusion and the lower protrusion.

[0023] According to this structure, when the molding is mounted on the glass run channel body, after the upper fitting portion and the lower fitting portion of the molding are fitted with the upper protrusion portion and the lower protrusion portion of the glass run channel body from their front-rear direction one end portions, the molding is moved relative to the glass run channel body in the vehicle front-rear direction, thereby enabling the molding to be mounted at a desired position. At this time, the molding is curved in an upward convex manner similar to the glass run channel body, so that the force required to move the molding relative to the glass run channel body in the vehicle front-rear direction is small, and mounting can be completed.

[0024] The thickness of the upper fitting portion and the lower fitting portion according to the fifth aspect of the present disclosure may be set to be thinner than the thickness of a portion of the molding body on which the decorative tape is laminated.

[0025] According to this configuration, since the upper fitting portion and the lower fitting portion protruding toward the vehicle interior are thin, when the molding is attached to the glass run channel body, the molding is easily bent along the shape of the glass run channel body, resulting in good mounting workability of the molding.

[0026] The molding main body according to the sixth aspect of the present disclosure can be extruded so that the resin constituting the molding main body does not cover the upper end portion and the lower end portion of the surface of the decorative tape.

[0027] According to this configuration, when the decorative tape and the molding main body are co-extruded, the upper end portion and the lower end portion of the surface of the decorative tape are not covered with resin, so that moldability is good.

[0028] Effects of the Invention

[0029] As described above, since the decorative band is extruded on the vehicle outer side of the molding body, it is possible to provide a glass run channel for an automobile door that is light in weight, has a small number of parts, and can reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is a detailed description of the preferred embodiments of the present invention based on the accompanying drawings. It should be noted that the following description of the preferred embodiments is essentially only an example and is not intended to limit the present invention, its application objects or its use.

[0038] Figure 1 The figure is a side view of a left front door (automobile door) 1 including a left front door glass run channel (automobile door glass run channel) 10 according to an embodiment of the present invention, as viewed from the vehicle exterior (left side). The left front door 1 is arranged on the left front side of an automobile (not shown) and is used to open and close an opening (not shown) formed on the left front side of the automobile. The right front door is symmetrically arranged with the left front door, but is not shown. In addition, the automobile door glass run channel according to the present invention can also be arranged on the left and right rear doors, but is not shown.

[0039] It should be noted that, in the description of this embodiment, the front side of the vehicle is simply referred to as “front”, and the rear side of the vehicle is simply referred to as “rear.” In addition, the vehicle outer side and the vehicle inner side are defined as shown in the respective drawings.

[0040] (Door structure)

[0041] like Figure 1 As shown, the left front door 1 has a door body 2 and a window frame 3, wherein the door body 2 constitutes the approximate lower half of the left front door 1, and the window frame 3 constitutes the approximate upper half of the left front door 1. The front end of the door body 2 is mounted on a pillar of the vehicle body via a hinge having a rotating shaft extending in the up-down direction, but it is not shown in the figure. The door body 2 is composed of an inner plate (not shown) and an outer plate 2a, and the inner plate and the outer plate 2a are made of steel plates, etc. The interior of the door body 2 can accommodate a window glass 4 that performs a lifting action and a lifting device (not shown) for lifting the window glass 4.

[0042] The window frame 3 functions as a frame (sash) for holding the peripheral edge of the window glass 4, and extends to form a window opening 7. The window glass 4 opens and closes the window opening 7 formed by the window frame 3. Figure 2 As shown, the window frame 3 of this embodiment is constructed by combining an outer panel 5 and an inner panel 6 formed by press-forming steel plates or the like.

[0043] like Figure 1As shown, the window frame 3 is composed of a frame upper edge portion 3a and a frame rear edge portion 3b. The frame upper edge portion 3a extends from the front portion of the upper edge of the door body 2 to the rear side and is bent in a convex manner. The frame rear edge portion 3b extends upward from the rear portion of the upper edge of the door body 2. The upper end portion of the frame rear edge portion 3b is connected to the rear end portion of the frame upper edge portion 3a to form the window frame 3.

[0044] It should be noted that the shape of the window frame 3 is not limited to the shape shown in the figure, and can also be a shape that is bent upward as a whole, and the position of the bent portion, the inclination angle of the frame upper edge portion 3a, and the curvature can be arbitrarily set in a manner corresponding to the shape of the roof of the vehicle body. In addition, a frame front edge portion (not shown) extending in the up-down direction can also be set at the front of the window frame 3. In addition, a door mirror mounting portion 3d for mounting a door mirror (not shown) is provided at the front of the window frame 3, but it can be set as needed.

[0045] like Figure 2 As shown, a glass run channel mounting plate portion 8 extending toward the vehicle outer side is formed on the frame upper side portion 3a of the window frame 3. The glass run channel mounting plate portion 8 is curved in a convex manner upward and is formed by the vehicle outer side portions of the outer panel 5 and the inner panel 6.

[0046] That is, the vehicle outer side portion of the outer panel 5 extends substantially horizontally and continuously in the front-rear direction. The vehicle outer side portion of the inner panel 6 also extends substantially horizontally and continuously in the front-rear direction. The glass run channel mounting plate portion 8 is formed by overlapping the lower surface of the vehicle outer side portion of the inner panel 6 on the upper surface of the vehicle outer side portion of the outer panel 5. It should be noted that the glass run channel mounting plate portion 8 can be formed by either the outer panel 5 or the inner panel 6 in addition to being formed by both the outer panel 5 and the inner panel 6.

[0047] (Structure of glass run channel for automobile doors)

[0048] The left front door glass run channel 10 is formed to cover at least the vehicle outer side of the window frame 3. The details will be described later. The left front door glass run channel 10 is mounted on the frame upper side 3a of the window frame 3 from the vehicle outer side, and functions as a sealant that seals the gap between the window frame 3 and the window glass 4. The left front door glass run channel 10 is formed to also cover the glass run channel mounting plate portion 8 that is the vehicle outer side portion of the window frame 3.

[0049] like Figure 1As shown in FIG. 1 , the left front door glass run channel 10 includes a glass run channel upper edge 11, a glass run channel front side vertical edge 12, and a glass run channel rear side vertical edge 13. The glass run channel upper edge 11, the glass run channel front side vertical edge 12, and the glass run channel rear side vertical edge 13 are formed as one body. The glass run channel upper edge 11 extends in the front-rear direction along the frame upper edge 3a as the upper part of the window frame 3, and the glass run channel upper edge 11 is bent in a convex manner upward along the frame upper edge 3a when the glass run channel is mounted on the glass run channel mounting plate 8.

[0050] like Figure 2 As shown, the left front door glass run channel 10 includes a glass run channel main body 20 having a slot 14 into which the glass run channel mounting plate 8 is inserted, and a molding 30, which is mounted on the vehicle outer side of the glass run channel main body 20 and extends in the front-rear direction. The molding 30 is mounted only on the glass run channel main body 20 constituting the glass run channel upper side 11, and is not mounted on the glass run channel front side longitudinal side 12 and the glass run channel rear side longitudinal side 13.

[0051] The glass run channel body 20 includes an upper plate portion 21 extending along the upper surface of the glass run channel mounting plate portion 8, a lower plate portion 22 extending along the lower surface of the glass run channel mounting plate portion 8, and a vehicle outer side plate portion 23 extending in the up-down direction from the vehicle outer side end portion of the upper plate portion 21 to the vehicle outer side end portion of the lower plate portion 22. The upper plate portion 21, the lower plate portion 22, and the vehicle outer side plate portion 23 are integrally formed by extrusion molding.

[0052] A slot 14 is formed between the upper plate 21 and the lower plate 22. The slot 14 opens between the vehicle inner end of the upper plate 21 and the vehicle inner end of the lower plate 22 and extends in the front-rear direction. The bottom of the slot 14 is formed by the vehicle outer plate 23.

[0053] A plurality of upper engaging protrusions 21a protruding downward are formed on the lower surface of the upper plate portion 21 at intervals in the vehicle interior and exterior direction. The lower end of the upper engaging protrusion 21a can be formed to contact the upper surface of the glass run channel mounting plate portion 8. The flip-up portion 8a abuts and engages with the upper engaging protrusion 21a located on the vehicle interior side from the vehicle exterior side, and the flip-up portion 8a protrudes upward from the upper surface of the glass run channel mounting plate portion 8. Therefore, the left front door glass run channel 10 is not easily detached from the glass run channel mounting plate portion 8. In addition, a plurality of lower engaging protrusions 22a protruding upward are formed on the upper surface of the lower plate portion 22 at intervals in the vehicle interior and exterior direction.

[0054] An upper sealing lip 24 is provided on the upper portion of the vehicle outer side of the glass run channel body 20 so as to protrude upward, and the upper sealing lip 24 is bent toward the vehicle outer side by contacting with the vehicle body 100. The base end of the upper sealing lip 24 is fixed to the vehicle outer side portion of the upper surface of the upper plate portion 21 and is formed integrally therewith.

[0055] An inner seal lip 25 is provided on the upper portion of the glass run channel body 20 on the vehicle inner side so as to protrude upward. The inner seal lip 25 is bent toward the vehicle outer side by contacting the vehicle body 100. The base end of the inner seal lip 25 is fixed to the vehicle inner side portion of the upper surface of the upper plate portion 21 and is formed integrally therewith.

[0056] In addition, an inner seal portion 26 is formed to protrude downward at the vehicle inner end portion of the upper plate portion 21. The inner seal portion 26 is fixed to and integrally formed with the vehicle inner end portion of the upper plate portion 21. The lower end portion of the inner seal portion 26 contacts the upper surface of the glass run channel mounting plate portion 8.

[0057] A lower seal portion 27 is provided at the lower portion of the glass run channel body 20 on the vehicle outer side so as to protrude downward. The base end of the lower seal portion 27 is fixed to the vehicle outer side portion of the lower surface of the lower plate portion 22 and is formed integrally therewith. The lower portion of the lower seal portion 27 is bent toward the vehicle inner side. The lower portion of the lower seal portion 27 contacts the vehicle outer side surface of the window glass 4 in the closed state.

[0058] A lower seal portion 28 is provided at the lower portion of the glass run channel body 20 on the vehicle interior side so as to protrude downward. The base end portion of the lower seal portion 28 is fixed to the end surface of the lower plate portion 22 on the vehicle interior side and is formed integrally therewith. The lower portion of the lower seal portion 28 is bent toward the vehicle interior side. The lower portion of the lower seal portion 28 is in contact with the outer panel 5 of the window frame 3. In addition, the lower seal portion 28 is also in contact with the vehicle interior side surface of the window glass 4 in the closed state.

[0059] An intermediate sealing lip 29 is provided between the base end of the lower side sealing portion 27 and the base end of the lower side sealing portion 28 on the lower surface of the lower plate portion 22. The base end of the intermediate sealing lip 29 is fixed to the middle portion of the lower surface of the lower plate portion 22 in the vehicle interior and exterior direction and is formed integrally. The intermediate sealing lip 29 is formed to extend obliquely downward toward the vehicle exterior and to contact the upper end of the window glass 4 in the closed state.

[0060] As materials constituting the upper seal lip 24, the inner seal lip 25, the inner seal portion 26, the lower seal portion 27, the lower seal portion 28, and the intermediate seal lip 29, for example, a rubber mainly composed of various polymers such as EPDM (ethylene propylene diene monomer rubber), or a material having elasticity such as various TPEs (thermoplastic elastomers) such as TPO (olefin thermoplastic elastomer) and TPS (styrene thermoplastic elastomer) can be used. The rubber or TPE may be a foamed material or a solid material.

[0061] The upper seal lip 24 , the inner seal lip 25 , the inner seal portion 26 , the lower seal portion 27 , the lower seal portion 28 , and the middle seal lip 29 constitute the glass run channel body 20 together with the upper plate portion 21 , the lower plate portion 22 , and the outer side plate portion 23 .

[0062] The vehicle outer side plate portion 23 of the glass run channel body 20 is a portion to which the molding body of the molding 30 is mounted. A protrusion 23a is formed on the vehicle outer side surface of the vehicle outer side plate portion 23. The protrusion 23a protrudes toward the vehicle outer side and extends in the front-rear direction. An upper protrusion 23b protrudes upward and extends in the front-rear direction, and a lower protrusion 23c protrudes downward and extends in the front-rear direction are formed at the top end of the protrusion 23a.

[0063] like Figure 1 As shown, the molding 30 is a component used as part of the vehicle design. Figure 3 As shown in the enlarged cross-sectional view of the center molding 30, the molding 30 includes a molding body 31 made of resin and a decorative band 32. The molding body 31 is formed in a plate shape extending in the front-rear direction and also in the up-down direction. Figure 2 As shown, the upper end of the molding body 31 is located above the upper end of the vehicle outer side plate 23 of the glass run channel body 20, and the lower end of the molding body 31 is located below the lower end of the vehicle outer side plate 23 of the glass run channel body 20. The dimension of the molding body 31 in the vertical direction is set to be longer than the dimension of the vehicle outer side plate 23 of the glass run channel body 20 in the vertical direction.

[0064] The molding body 31 is made of the same hard resin material as the resin material constituting the upper plate portion 21 of the glass run channel body 20, and is obtained by extrusion molding using an extrusion molding machine (not shown). Since the molding body 31 is obtained by extrusion molding, the molding body 31 has the same cross-sectional shape from one end in the longitudinal direction to the other end in the longitudinal direction.

[0065] An upper fitting portion 31a and a lower fitting portion 31b are formed on the inner side surface of the molding body 31. The upper fitting portion 31a is fitted with the upper protrusion 23b of the glass run channel body 20, and the lower fitting portion 31b is fitted with the lower protrusion 23c. The wall thickness of the upper fitting portion 31a and the lower fitting portion 31b is set to be thicker than the wall thickness T1 (such as the wall thickness T2 of the portion of the molding body 31 on which the decorative tape 32 is laminated (the portion extending in the vertical direction)). Figure 3 shown) thin.

[0066] The upper fitting portion 31a is bent downward after protruding toward the vehicle interior, so as to surround the upper protrusion 23b from above and the vehicle interior. The lower fitting portion 31b is bent upward after protruding toward the vehicle interior, so as to surround the lower protrusion 23c from below and the vehicle interior. The protrusion 23a of the glass run channel body 20 is arranged between the lower end of the upper fitting portion 31a and the upper end of the lower fitting portion 31b. In a state where the upper fitting portion 31a and the lower fitting portion 31b are respectively fitted with the upper protrusion 23b and the lower protrusion 23c, the molding 30 can move relative to the glass run channel body 20 in the front-rear direction.

[0067] An upper protrusion 31c and a lower protrusion 31d are formed at the upper end and the lower end of the molding body 31, respectively. The upper protrusion 31c and the lower protrusion 31d both protrude toward the vehicle interior and extend in the front-rear direction. The upper protrusion 31c is inclined so as to be located downward as it goes toward the vehicle interior. The thickness T2 of the lower protrusion 31d is set thicker than the thickness T3 of the upper protrusion 31c. In addition, when the thickness T2 of the lower protrusion 31d is compared with the thickness T1 of the portion of the molding body 31 extending in the vertical direction, the thickness T2 of the lower protrusion 31d is thicker.

[0068] As described above, the window frame 3 is curved in an upward convex manner along the shape of the roof of the automobile, and therefore, the glass run channel body 20 in a state of being mounted on the window frame 3 is also curved in an upward convex manner. Therefore, it is preferable that the molding 30 is also curved in an upward convex manner corresponding to the shape of the glass run channel body 20. In this embodiment, since the wall thickness of the lower protrusion 31d is thicker than that of the upper protrusion 31c, the resin of the lower protrusion 31d contracts more during the cooling process of the resin after extrusion molding, and thus the molding 30 naturally swells as shown in FIG. Figure 4 In addition, as shown in FIG. Figure 5 As shown, the molding 30 is gently curved in a convex manner toward the vehicle outer side. The curved shape toward the vehicle outer side is also adopted to match the shape of the glass run channel main body 20 in the state of being mounted on the vehicle window frame 3.

[0069] The curved shape of the molding 30 in a side view can be changed according to at least one of the thickness of the upper protrusion 31c and the thickness of the lower protrusion 31d. The molding 30 is more curved when the thickness of the upper protrusion 31c is thinner, the thickness of the lower protrusion 31d is thicker, and the difference between the thickness of the upper protrusion 31c and the thickness of the lower protrusion 31d is larger. On the contrary, the molding 30 is more gently curved when the difference between the thickness of the upper protrusion 31c and the thickness of the lower protrusion 31d is smaller.

[0070] The decorative band 32 is co-extruded on the vehicle outer side of the molding body 31. That is, the decorative band 32 is extruded at the same time as the resin material constituting the molding body 31 is extruded from a die head (not shown) by an extrusion molding machine, so that the decorative band 32 and the resin material constituting the molding body 31 are integrally formed to form the molding body 31 having the decorative band 32. The decorative band 32 is a decorative band of a metallic color having a metallic luster on the surface. The metallic color refers to, for example, a stainless steel color, an aluminum color, a copper color, etc., but is not limited to these, as long as it has various metallic lusters. As another embodiment, for example, a black decorative band may be used. Such a decorative band 32 has been known in the past, and for example, a decorative band 32 having a metal plating layer and a protective layer as a surface layer and a base material layer as a back layer can be used. In this case, the back layer is made of a material having adhesiveness with the resin material constituting the molding body 31. The thickness of the decorative band 32 is much thinner than the stainless steel plate or aluminum plate conventionally used for moldings, and the weight is light.

[0071] The upper portion of the decorative tape 32 extends to reach the upper surface of the upper protrusion 31c of the molding body 31. Therefore, the upper surface of the upper protrusion 31c is covered by the upper portion of the decorative tape 32. The top end of the upper contact portion 40 of the glass run channel body 20 contacts the upper portion of the decorative tape 32 from above. As a result, the upper end of the decorative tape 32 is covered by the upper contact portion 40, so that it cannot be seen from the outside, which is beautiful.

[0072] In addition, the lower portion of the decorative band 32 extends and reaches the lower surface of the lower protrusion 31d. Therefore, the lower surface of the lower protrusion 31d is covered by the lower portion of the decorative band 32. The top end of the lower contact portion 41 of the glass run channel body 20 contacts the lower portion of the decorative band 32 from below. As a result, the lower end of the decorative band 32 is covered by the lower contact portion 41, so it cannot be seen from the outside, which is beautiful.

[0073] The molding body 31 is extruded so that the resin constituting the molding body 31 does not cover the upper end and the lower end of the surface of the decorative tape 32. Specifically, the molding body 31 is extruded so that the upper portion of the decorative tape 32 extends to the upper surface of the upper protrusion 31c, but the resin constituting the molding body 31 does not exist on the surface of the upper portion of the decorative tape 32. In addition, the molding body 31 is extruded so that the lower portion of the decorative tape 32 extends to the lower surface of the lower protrusion 31d, but the resin constituting the molding body 31 does not exist on the surface of the lower portion of the decorative tape 32. In this way, the molding body 31 only needs to be formed so that the entire surface of the decorative tape 32 is exposed from the resin constituting the molding body 31, so the moldability during extrusion molding is good.

[0074] The molding 30 obtained by extrusion molding is in a continuous long strip shape, and its length is longer than the dimension of the glass run channel body 20 in the front-rear direction. When the molding 30 is installed on the glass run channel body 20, the long strip molding 30 is cut to match the length of the glass run channel body 20. Figure 4 and Figure 5 As shown in FIG. 1 , the rear end of the cut molding 30 is open, and the upper protrusion 23b and the lower protrusion 23c of the glass run channel body 20 are respectively inserted into the upper fitting portion 31a and the lower fitting portion 31b from the open portion, and they are fitted together. Then, the molding 30 is installed in the correct position by moving the molding 30 backward relative to the glass run channel body 20. It should be noted that the molding 30 can be installed from the front or from the rear.

[0075] (Effects of the Implementation Methods)

[0076] As described above, according to the present embodiment, the molding 30 attached to the vehicle outer side of the glass run channel body 20 includes the molding body 31, which is a resin body formed by extrusion, and the decorative tape 32, which is co-extruded on the vehicle outer side of the molding body 31. By using the decorative tape 32 of a metallic color, the molding 30 having a metallic color on the vehicle outer side can be obtained without providing a stainless steel plate or an aluminum plate. The resin and the decorative tape 32 constituting the molding body 31 are lighter than the stainless steel plate or aluminum plate used as materials for the conventional metal molding, and the decorative tape 32 is thinner than the stainless steel plate or the aluminum plate, so the weight of the molding 30 is reduced. In addition, since the decorative tape 32 is co-extruded when the molding body 31 is extruded, the molding body 31 and the decorative tape 32 are one component when the molding 30 is just manufactured, and the number of components does not increase. Therefore, it is possible to provide a glass run channel 10 for an automobile door that is lightweight, has a small number of components, and can reduce costs.

[0077] In addition, since the wall thickness of the lower protrusion 31d of the molding body 31 is thicker than that of the upper protrusion 31c, the resin of the lower protrusion 31d shrinks more during the cooling process of the resin after the molding body 31 is extruded. As a result, the molding 30 is naturally curved in an upward convex manner and has a shape extending along the glass run channel body 20. Therefore, when the molding 30 is attached to the glass run channel body 20, the molding 30 can be attached with a small force when the molding 30 is moved relative to the glass run channel body 20 in the front-rear direction in a state where the upper fitting portion 31a and the lower fitting portion 31b of the molding body 31 are respectively fitted with the upper protrusion 23b and the lower protrusion 23c of the glass run channel body 20. In short, the installation workability when the molding 30 is attached to the glass run channel body 20 is improved.

[0078] The above embodiments are merely examples in all aspects and should not be interpreted as limiting. In addition, modifications and changes within the scope of equivalents to the scope of the patent claims are within the scope of the present invention.
