Description

Technical Field

[0001] This invention relates to a glass run installed in the door frame of a vehicle door, such as an automobile. Background Technology

[0002] Improving the quietness of vehicles such as automobiles enhances passenger comfort, thus increasing attention on improving product competitiveness. Furthermore, electric vehicles, which are expected to rapidly become widespread in the future, lack the engines currently used in cars. Therefore, the main noises remaining after the engine noise is eliminated—road noise and wind noise—become more pronounced. Consequently, the necessity for technologies to reduce these noises has increased to an unprecedented level.

[0003] The sound of wind breaking is the sound produced by the wind coming into contact with the vehicle while it is in motion, which travels through the vehicle body and into the vehicle interior. It is known that the door glass, which is closest to the ears of the occupants in the vehicle interior, plays the most important role in this path. Countermeasures such as increasing the thickness of the door glass and setting up soundproof glass have been implemented, but the increase in weight and cost has created obstacles.

[0004] However, in addition to the door glass, the glass groove, which serves as a seal between the door glass and the door frame, can also reduce noise, especially in the high-frequency domain of 1 kHz or higher, and research has been conducted to increase this noise reduction effect.

[0005] As a technique for reducing noise caused by wind noise, the inventors of this invention focused on a scheme to reduce vibration by effectively dispersing the vibration energy of the door glass to the components that come into contact with the door glass through a so-called resistance matching method, and achieved noise reduction in Patent Document 1.

[0006] based on Figure 8 The technology of Patent Document 1 will be described. The glass slide 10 is formed in the shape of a tunnel (the cross section is approximately “ko” shaped) with the bottom wall 20, the outer side wall 30 and the inner side wall 40 as the basic framework.

[0007] On the inner side of the outer sidewall 30, a thick wall portion 31 is formed that protrudes inward and slides in contact with the door glass 4, and has a higher hardness than the outer sidewall 30. In addition, a plurality of convex ribs 32 are formed continuously and parallel in the longitudinal direction on the inner surface of the thick wall portion 31.

[0008] The door glass 4 is brought into sliding contact with the thick-walled portion 31 formed on the outer sidewall 30 of the vehicle, making the hardness of the thick-walled portion 31 higher than that of the outer sidewall 30. This reduces the rigidity difference between the door glass 4 and the thick-walled portion 31, and through resistance matching, the vibration of the door glass 4 can be effectively dispersed to the thick-walled portion 31. As a result, noise caused by wind noise can be reduced.

[0009] In addition, multiple convex ribs 32 are formed continuously and parallel in the length direction on the inner surface of the thick-walled portion 31, thereby preventing dust, dirt, foreign objects, etc. from getting stuck in the thick-walled portion 31 when the door glass 4 is raised or lowered, thus preventing the associated abnormal noise.

[0010] Patent Document 1: Japanese Patent Application No. 2021-140940

[0011] However, in Patent Document 1, a convex rib 32 is formed to prevent dust, foreign objects, etc. from getting stuck inside the thick-walled part of the vehicle. Therefore, the contact between the door glass 4 and the thick-walled part 31 of the glass groove 10 is not a surface contact, but a line contact (point contact in cross-section). As a result, the effect of increased rigidity based on the thick-walled part cannot be fully utilized, and the noise reduction effect caused by wind noise is insufficient. Summary of the Invention

[0012] To solve the above problems, the present invention, technical solution 1, is a glass slide channel, which uses a bottom wall, an outer side wall, and an inner side wall as a basic frame. The basic frame is installed in the door frame groove formed in the door frame to guide the raising and lowering of the door glass. The feature is that a thick wall portion is formed on the inner side of the outer side wall. The thick wall portion protrudes into the inner side of the vehicle and slides in contact with the door glass. The hardness is higher than that of the outer side wall. When the thickness of the thick wall portion is set as t1 and the sum of the thicknesses of the thick wall portion and the outer side wall is set as T, t1 is greater than or equal to 0.4T and less than or equal to 1.0T.

[0013] In the present invention of technical solution 1, a thick-walled portion is formed on the inner side of the outer sidewall of the vehicle. This thick-walled portion protrudes inward and slides in contact with the door glass, and its hardness is higher than that of the outer sidewall. When the thickness of the thick-walled portion is t1 and the sum of the thicknesses of the thick-walled portion and the outer sidewall is T, t1 is greater than or equal to 0.4T and less than or equal to 1.0T. Therefore, by forming a thicker thick-walled portion, the rigidity of the glass slide can be increased. Even when a convex rib is formed on the inner side of the thick-walled portion, the effect of the thick-walled portion can be fully utilized, and the noise reduction effect caused by wind noise can be increased. When t1 is less than 0.4T, the rigidity of the outer sidewall of the glass slide, including the thick-walled portion, is not sufficiently increased, and the effect of the thick-walled portion is difficult to fully utilize.

[0014] Furthermore, when t1 is less than 1.0T, the thick-walled portion can be formed as a single block, and can be divided into a portion that slides in contact with the door glass and a portion inside the outer sidewall of the vehicle. Examples of division within the outer sidewall include being embedded inside the outer sidewall, being exposed on the outer sidewall, and both of the above.

[0015] Here, "the rigidity of the glass slide" is represented by the increase in the amount of displacement of the glass slide relative to the pressing part when the glass is pressed by the door window. Therefore, "the increase in the rigidity of the glass slide" in the relationship between displacement and reaction force refers to the increase in its slope (gradient).

[0016] Technical Solution 2 of the present invention is a glass slide, which has a bottom wall, an outer side wall and an inner side wall as the basic frame. The basic frame is installed in the door frame groove formed in the door frame to guide the raising and lowering of the door glass. The feature is that a thick wall portion is formed on the inner side of the outer side wall. The thick wall portion protrudes into the inner side of the vehicle and slides in contact with the door glass. The hardness is higher than that of the outer side wall. An insert is embedded on the outer side of the thick wall portion of the outer side wall.

[0017] In the present invention of technical solution 2, a thick wall portion is formed on the inner side of the outer sidewall of the glass slide. The thick wall portion protrudes into the inner side of the vehicle and slides in contact with the door glass. Moreover, the hardness is higher than that of the outer sidewall. An insert is embedded in the outer side of the thick wall portion of the outer sidewall. Therefore, the rigidity of the glass slide can be increased by using the outer sidewall of the vehicle with the embedded thick wall portion and the insert. Even when a convex rib is formed on the inner side of the thick wall portion, the effect of the thick wall portion can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0018] The present invention in technical solution 3 is based on the invention in technical solution 2, wherein the insert is a metal plate, a conductor frame, or a conductor core.

[0019] In the present invention of technical solution 3, the insert is a metal plate, a lead frame, or a lead core material. Therefore, during the molding of the glass slide, a relatively thin plate shape can be embedded in the outer sidewall of the vehicle through co-extrusion molding. As a result, the rigidity of the glass slide can be increased, the effect of the thick-walled portion can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0020] Here, a conductor frame refers to a thin sheet material that is formed by bending a thin conductor, which serves as the core material, into a serrated shape within a certain width and holding the core material in the length direction by multiple filaments.

[0021] Technical Solution 4 of the present invention is a glass slide, which has a bottom wall, an outer side wall and an inner side wall as a basic frame. The basic frame is installed in the door frame groove formed in the door frame to guide the raising and lowering of the door glass. The feature is that a thick wall portion is formed on the inner side of the outer side wall, which protrudes inward and slides in contact with the door glass. A semi-rigid material portion is formed on the part of the outer side wall that connects with the thick wall portion. The hardness of the semi-rigid material portion is less than that of the thick wall portion but greater than that of the outer side wall except for the semi-rigid material portion.

[0022] In the present invention, technical solution 4, a thick-walled portion is formed on the inner side of the outer sidewall of the vehicle. This thick-walled portion protrudes inward and slides in contact with the door glass. A semi-rigid material portion is formed on the portion of the outer sidewall that connects to the thick-walled portion. The hardness of the semi-rigid material portion is less than that of the thick-walled portion but greater than that of the rest of the outer sidewall. Therefore, the rigidity of the outer sidewall with the thick-walled portion is increased. As a result, the rigidity of the glass slide is increased, so even when a convex rib is formed on the inner side of the thick-walled portion, the effect of the thick-walled portion can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0023] The effects of the invention

[0024] A thick-walled portion is formed on the inner side of the outer sidewall of the glass slide. This thick-walled portion protrudes inward and slides in contact with the door glass. Its hardness is higher than that of the outer sidewall of the vehicle. When the thickness of the thick-walled portion is set as t1 and the sum of the thicknesses of the thick-walled portion and the outer sidewall of the vehicle is set as T, t1 is greater than or equal to 0.4T and less than or equal to 1.0T. Therefore, forming a thicker thick-walled portion can increase the rigidity of the glass slide. Even when a convex rib is formed on the inner side of the thick-walled portion, the effect of the thick-walled portion can be fully utilized, which can increase the reduction effect of noise caused by wind noise.

[0025] In addition, a thick wall portion is formed on the inner side of the outer sidewall of the vehicle. This thick wall portion protrudes inward and slides in contact with the door glass. It is harder than the outer sidewall of the vehicle. An insert is embedded on the outer side of the thick wall portion of the outer sidewall. Therefore, the rigidity of the glass slide can be increased by using the outer sidewall with the thick wall portion and the insert. Even when there are convex ribs formed on the inner side of the thick wall portion, the effect of the thick wall portion can be fully utilized, which can increase the noise reduction effect caused by wind noise.

[0026] Furthermore, a thick-walled section is formed on the inner side of the outer sidewall of the vehicle. This thick-walled section protrudes inward and slides in contact with the door glass. A semi-rigid material section, made of a semi-rigid material, is formed at the portion of the outer sidewall that connects to the thick-walled section. The hardness of the semi-rigid material section is less than that of the thick-walled section but greater than that of the rest of the outer sidewall. This increases the rigidity of the outer sidewall where the thick-walled section is formed. As a result, the rigidity of the glass slide is increased, so even when convex ribs are formed on the inner side of the thick-walled section, the effect of the thick-walled section can be fully utilized, increasing the reduction of noise caused by wind noise.

[0035] In the following description, parts that are identical to those in the background art are described with the same names and the same reference numerals. Based on Figures 1 to 3 The first embodiment of the present invention will be described. Figure 1This is a front view of the left front door 1 of a car, viewed from the outside. A door frame 3 is mounted on the upper part of the door body 2 that constitutes the front door 1. A window opening is formed by the door frame 3 and the upper edge of the door body 2. A glass slide 10 is installed on the inner periphery of the window opening and inside the door body 2 to guide the raising and lowering of the door glass 4. Furthermore, this invention can be applied not only to the left front door 1, but also to the right front door and the left and right rear doors. Additionally, it can be applied to sliding doors with raised and lowered windows.

[0036] Figure 2 This is a simplified front view of the glass slide 10 viewed from the outside of the vehicle. The glass slide 10 is composed of the following components: a first extrusion molding section 11, corresponding to the horizontal frame of the door frame 3; a second extrusion molding section 12, corresponding to the vertical frame of the front side of the front door 1; and a third extrusion molding section 13, corresponding to the vertical frame of the rear side. The front end of the first extrusion molding section 11 is connected to the upper end of the second extrusion molding section 12 via a first molding section 14. Furthermore, the rear end of the first extrusion molding section 11 is connected to the upper end of the third extrusion molding section 13 via a second molding section 15.

[0037] Figure 3 (a) is related to Figure 1 The sectional view corresponding to line XX. Figure 3 (b) is related to Figure 1 The cross-sectional view corresponding to the YY line. The glass slide 10 is formed in a tunnel shape (the cross-section is approximately "ko" shaped) with the bottom wall 20, the outer side wall 30, and the inner side wall 40 as the basic framework. The bottom wall 20 is connected to the outer side wall 30 and the inner side wall 40 through the grooves 21 on the outer and inner sides of the vehicle, so that it can be unfolded in a free state.

[0038] (Bottom wall 20)

[0039] The bottom wall 20 is formed in an approximately plate-like shape, and a plurality of bottom wall recesses 22 are continuously and parallelly formed in the longitudinal direction on the inner surface of the bottom wall 20 (on the four sides of the door glass). Additionally, in Figure 3 In (a), a bottom wall sealing lip 23 is formed on the outer surface of the bottom wall 20. The bottom wall sealing lip 23 abuts against the tunnel-shaped (cross-section approximately “ko”-shaped) door frame groove 5 formed in the door frame 3, sealing the bottom wall 20 and the door frame groove 5.

[0040] (Outside of the vehicle)

[0041] exist Figure 3In (a), on the outer side of the vehicle outer sidewall 30, near the connection with the bottom wall 20 and in the direction of the front end of the vehicle outer sidewall 30, a first vehicle outer retaining lip 33 and a second vehicle outer retaining lip 34 are formed to engage with the door frame groove 5, and the door frame groove 5 formed by the first vehicle outer retaining lip 33 and the second vehicle outer retaining lip 34 are used to retain the curved door frame groove 5.

[0042] A covering lip 36 is formed on the front end 39 of the outer sidewall 30, on the side opposite to the bottom wall 20 in the direction of the door glass 4. The covering lip 36 abuts against the outer side surface of the door glass 4, suppressing the intrusion of rainwater and dust into the thick wall portion 31 and preventing the deterioration of the thick wall portion 31, which will be described later. In addition, it improves the sealing performance relative to the door glass 4.

[0043] A locking portion 35 is formed at the base of the cover lip 36 facing outwards, which fixes the end of the pillar trim 6 and seals the gap between the pillar trim 6 and the surface of the door glass 4.

[0044] exist Figure 3 In (b), a protrusion 55 is formed on the outer side of the middle portion of the outer sidewall 30. Additionally, an outer sealing lip 38 is formed on the outer sidewall 30, extending from the front end 39 of the outer sidewall towards the inner and outer sides of the vehicle and towards the bottom wall 20. The inner side of the sealing lip 38 slides in contact with the door glass 4. The outer sealing lip 38 does not abut against the thick-walled portion 31 described later.

[0045] Figure 3 (a) and Figure 3 (b) The outer side of the protrusion 55 of the outer sidewall 30 of the vehicle is in contact with the door frame groove 5. The rigidity of the outer sidewall 30 of the vehicle, which is clamped between the door glass 4 and the door frame groove 5, can be increased by the surface contact.

[0046] (Inside the vehicle)

[0047] exist Figure 3 In (a), an inner sealing lip 41 is formed on the outer side of the inner sidewall 40. The inner sealing lip 41 extends outward from the front end 47 of the inner sidewall and the bottom wall 20 towards the outer side and towards the bottom wall 20. The outer side of the lip 41 slides in contact with the door glass 4. The inner sealing lip 41 is designed such that when the door glass 4 slides in contact with the thick wall portion 31 of the outer sidewall 30 and the inner sealing lip 41, the reaction force on the door glass 4 from the outer side and the inner side is greater than that on the outer side, and the pressing force of the door glass 4 towards the thick wall portion 31 is increased.

[0048] On the outer side of the inner sidewall 40 of the vehicle and on the side closer to the bottom wall 20 than the inner sealing lip 41, a secondary lip 42 is formed in the opposite direction to the inner sealing lip 41. The front end of the secondary lip 42 abuts against the inner side of the inner sealing lip 41, and the secondary lip 42 assists the inner sealing lip 41 in pressing the inner side of the door glass 4 toward the outer side of the vehicle.

[0049] On the inner side of the vehicle interior sidewall 40, near the connection with the bottom wall 20 and in the direction of the front end of the inner sidewall 40, a first inner side retaining lip 43 and a second inner side retaining lip 44 are formed to engage with the curved portion of the door frame groove 5 having a curved portion. Furthermore, an abutting lip 45 is formed between the first inner side retaining lip 43 and the second inner side retaining lip 44. The inner sidewall 40 is held in the curved door frame groove 5 by the first inner side retaining lip 43, the second inner side retaining lip 44, and the abutting lip 45.

[0050] A cover lip 46 is formed at the front end 47 of the inner side wall 40 facing the inner side of the vehicle. The cover lip 46 abuts against the door frame groove 5 to prevent the intrusion of rainwater, dust and noise and to improve the sealing performance relative to the door frame groove 5.

[0051] On the other hand, Figure 3 In (b), a first inner-side retaining lip 43 and a second inner-side retaining lip 44 are formed on the inner side of the inner side wall 40, which engage with the curved portion of the door frame groove 5. In addition, a covering lip 46 is formed on the front end 47 of the inner side wall 40 facing the inner side. The inner side wall 40 is held in the curved door frame groove 5 by the second inner-side retaining lip 44 and the covering lip 46.

[0052] (Thick-walled section 31)

[0053] like Figure 3 (a) and Figure 3 As shown in (b), a thick wall portion 31 is formed on the inner side of the outer sidewall 30 of the vehicle, protruding inward and slidingly contacting the door glass 4, and having a higher hardness than the outer sidewall 30. By making the door glass 4 slide in contact with the thick wall portion 31 formed on the outer sidewall 30, the hardness of the thick wall portion 31 is higher than that of the outer sidewall 30, thereby reducing the rigidity difference between the door glass 4 and the thick wall portion 31. Through resistance matching, the vibration of the door glass 4 can be effectively dispersed to the thick wall portion 31, thus reducing noise caused by wind noise.

[0054] Multiple convex ribs 32 are formed continuously and parallel along the length of the inner surface of the thick-walled portion 31. The ribs 32 prevent dust, dirt, foreign objects, etc. from getting stuck in the thick-walled portion 31 when the door glass 4 is raised or lowered, and prevent the generation of abnormal noises associated with it.

[0055] This first embodiment and Figure 8 Compared to the thick-walled portion 31, the thick-walled portion 31 is formed to be thicker. In this first embodiment, when the thickness of the thick-walled portion 31 is set to t1 and the sum of the thicknesses of the thick-walled portion 31 and the outer sidewall 30 of the vehicle is set to T, t1 is set to 0.7T.

[0056] By forming a thicker wall portion 31, the rigidity of the glass slide 10 can be increased. Even when a convex rib 32 is formed on the inner side of the thick wall portion 31, the effect of the thick wall portion 31 can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0057] Furthermore, from the viewpoint of increasing the rigidity of the outer sidewall 30 of the glass slide 10, it is preferable that the thickness t1 of the thick-walled portion 31 is greater than or equal to 0.4T. Alternatively, when the thickness t1 of the thick-walled portion 31 is less than 1.0T, the thick-walled portion 31 can be formed as a single block, with the thick-walled portion 31 divided into a portion that slides in contact with the door glass 4 and a portion formed within the outer sidewall 30. The case where the thick-walled portion 31 is divided and formed within the outer sidewall 30 can be, for example, embedded inside the outer sidewall 30, exposed on the outer side of the outer sidewall 30, or a combination of both.

[0058] here, Figure 3 (b) is as follows: the thick-walled portion 31 is formed as a single block, and the thickness t1 of the thick-walled portion 31 is set to t1 = 0.7T. On the other hand, Figure 3 (a) is as follows: the thick-walled portion 31 is divided into a portion that slides in contact with the door glass 4 and a portion exposed on the outer sidewall 30 of the vehicle. The thickness of the thick-walled portion 31 on the door glass 4 side is set as t2, and the thickness of the thick-walled portion 31 exposed on the outer sidewall is set as t3. The total thickness of these thicknesses is the thickness t1 of the thick-walled portion 31, i.e., t1 = t2 + t3, and is set as t1 = 0.7T. Furthermore, in Figure 3 In (a), it is plotted as t2<t3, but it can also be t2≥t3.

[0059] In this embodiment, the glass groove 10, except for the thick-walled portion 31, uses an olefinic thermoplastic elastomer (TPO) with an IRHD (International Rubber Hardness) of 80±5, while the thick-walled portion 31 uses TPO with an IRHD of 100±5, and is manufactured by extrusion molding (co-extrusion molding). Furthermore, in... Figure 3 In the case where the thick-walled portion 31 is formed by the division shown in (a), the thick-walled portion 31 on the outer side of the vehicle (the portion t3) does not contact the door glass 4, so a TPO of 85 to 105 can be used in the IRHD, which can be different from the thick-walled portion 31 on the inner side of the vehicle (the portion t2).

[0060] Furthermore, in embodiments of the present invention, the material constituting the glass slide 10 may be formed from rubber, thermoplastic elastomers, soft synthetic resins, etc., in addition to olefin-based thermoplastic elastomers (TPO). From the viewpoints of weather resistance, recyclability, and cost, EPDM (ethylene propylene diene monomer rubber) is preferred in the case of rubber, and dynamically crosslinked thermoplastic elastomers (TPV) are preferred as thermoplastic elastomers.

[0061] Next, based on Figure 4 (a) and Figure 4 (b) A second embodiment of the present invention will be described. In this second embodiment, the difference from the first embodiment described above is that, in this second embodiment, the thickness of the thick-walled portion 31 is... Figure 8 The same applies, but an insert 51 is embedded in the outer sidewall 30 of the outer sidewall of the thick-walled portion 31.

[0062] In this second embodiment, a cold-rolled steel sheet (SPCC) with a thickness of 0.5 mm is used. Furthermore, when embedded in the outer sidewall 30 of the glass channel 10, its thickness is preferably 0.5 mm to 1.0 mm. The material is not limited to SPCC and can also be other metal materials such as aluminum or stainless steel. Furthermore, regarding the metal sheet, a perforated metal mesh or a stamped metal part can also be used. The insert 51 is extruded together with the glass channel 10 (co-extrusion molding).

[0063] The metal plate insert 51 is embedded in the outer sidewall 30 of the vehicle outside the thick wall portion 31, which can increase the rigidity of the glass slide 10. Even when a convex rib 32 is formed on the inner side of the thick wall portion 31, the effect of the thick wall portion 31 can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0064] Next, based on Figure 5 (a) and Figure 5 (b) A third embodiment of the present invention will be described. The third embodiment is a variation of the second embodiment described above, in which a wire carrier 52 is embedded. As described above, a wire carrier is a sheet material formed by bending a thin wire, which serves as the core material, into a serrated shape within a certain width and holding it in the length direction by multiple threads, thereby forming a long strip-shaped sheet. In this third embodiment, an iron core material with a diameter of 0.5 mm is used as the core material. In addition, PET (polyethylene terephthalate) is used as a non-thermally fusible thread to hold the core material and suppress stretching in the length direction.

[0065] Furthermore, the core material is not limited to iron and can be other metals, and the diameter of the core material is not limited to 0.5 mm. However, from the viewpoint of increasing the rigidity of the outer sidewall 30 of the glass slide 10, a diameter of 0.5 mm to 1.0 mm is preferred.

[0066] Furthermore, the filaments that hold the core material and suppress stretching in the length direction are not limited to PET as non-thermal-melting filaments. For example, in the case of using EPDM rubber for the glass chute 10, thermally melted filaments that melt in a vulcanizing furnace can be used.

[0067] The wire frame 52 is embedded in the outer sidewall 30 of the vehicle outside the thick wall portion 31, which can increase the rigidity of the glass slide 10. Even when a convex rib 32 is formed on the inner side of the thick wall portion 31, the effect of the thick wall portion 31 can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0068] Next, based on Figure 6 (a) and Figure 6 (b) A fourth embodiment of the present invention will be described. The fourth embodiment is a variation of the second embodiment, in which five conductor cores 53 are embedded. Five iron cores with a diameter of 0.5 mm are used as the cores. However, the conductor cores 53 are not limited to iron cores and may be other metals, nor are their diameters limited to 0.5 mm. However, from the viewpoint of increasing the rigidity of the outer sidewall 30 of the glass slide 10, the diameter of the conductor cores 53 is preferably 0.5 mm to 1.0 mm. Furthermore, the number of embedded conductors is not limited to five, but from the viewpoint of increasing rigidity, it is preferable to embed more conductors.

[0069] By embedding the conductor core 53 in the outer sidewall 30 of the thick-walled portion 31, the rigidity of the outer sidewall 30 of the glass slide 10 can be increased. Even when a convex rib 32 is formed on the inner side of the thick-walled portion 31, the effect of the thick-walled portion 31 can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0070] Next, based on Figure 7 (a) and Figure 7 (b) A fifth embodiment of the present invention will be described. In the fifth embodiment, a semi-rigid material portion 54, made of a semi-rigid material, is formed on the outer sidewall 30 of the vehicle, at the portion connected to the thick-wall portion 31. The hardness of the semi-rigid material portion 54 is less than that of the thick-wall portion 31 but greater than that of the rest of the outer sidewall 30. The semi-rigid material portion 54 is formed to penetrate the outer sidewall 30 and to contact the door frame groove portion 5.

[0071] In this embodiment, the thick-walled portion 31 uses TPO with an IRHD (International Rubber Hardness) of 100±5, the portion forming the semi-rigid material portion 54 in the outer sidewall 30 uses TPO with an IRHD of 90±5, and the other portions of the glass groove 10 use olefin thermoplastic elastomer (TPO) with an IRHD of 80±5, and are manufactured by extrusion molding.

[0072] On the outer sidewall 30 of the vehicle, a semi-rigid material portion 54 made of semi-rigid material is formed at the part connected to the thick wall portion 31. Therefore, the rigidity of the glass slide 10 can be increased. Even when a convex rib 32 is formed on the inner side of the thick wall portion 31, the effect of the thick wall portion 31 can be fully utilized, and the noise reduction effect caused by wind noise can be increased.

[0073] When implementing this invention, it is not limited to the above-described embodiments. Various modifications can be made as long as they do not depart from the purpose of this invention.

[0074] For example, in the first to fifth embodiments described above, in order to increase the rigidity of the outer sidewall 30 of the vehicle where the thick-walled portion 31 is formed, inserts or the like are mainly embedded in the outer side of the thick-walled portion 31, thereby thickening the thick-walled portion 31 or forming a semi-rigid material portion 54. However, it can be configured and formed not only on the outer side of the vehicle connected to the thick-walled portion 31, but also over a wide area of ​​the outer sidewall 30. In this case, considering the assemblability of the glass groove 10 with respect to the door frame groove 5 of the door frame 3, the above-mentioned component can be configured and formed in an area other than the groove 21 on the outer side of the vehicle, which is the connection between the bottom wall 20 and the outer sidewall 30.

[0075] For example, the above Figure 3 (b) Figure 4 (b) Figure 5 (b) Figure 6 (b) and Figure 7 (b) The glass chute 10 of the embodiment can be applied to Figure 2 The first extrusion molding section 11.

[0076] In the first to fifth embodiments described above, the case in which a plurality of convex ribs 32 are formed on the inner surface of the thick-walled portion 31 has been described, but it can also be applied to thick-walled portions in which convex ribs 32 are not formed.
