[0008] (First embodiment) Hereinafter, a glass panel edge holding member according to a first embodiment will be described with reference to the drawings.

[0009] As shown in FIGS. 1 and 2, a glazing channel (hereinafter referred to as a "glazing channel") 100 holds a glass panel 10 of a fitting 1 such as a sliding window.

[0010] The fitting 1 is installed in an opening W of a building. The fitting 1 has a four-sided frame body 11 and two shoji screens 12, 12. The two shoji screens 12, 12 are slidably housed within the frame body 11.

[0011] In the following description, the horizontal direction connecting the outdoor side and the indoor side will be referred to as the indoor-outdoor direction, and the horizontal direction perpendicular to the indoor-outdoor direction will be referred to as the width direction.

[0012] The shoji screen 12 has a frame 13 and a glass panel 10. The frame 13 is formed in a four-sided frame shape. The frame 13 has an upper frame 14, a lower frame 15, and a pair of vertical frames 16, 16. The upper frame 14 and the lower frame 15 extend in the width direction. The vertical frames 16 extend in the up-down direction. Each vertical frame 16 connects the widthwise end of the upper frame 14 and the widthwise end of the lower frame 15.

[0013] The glass panel 10 is mounted in a glass groove 17 formed in the frame 13 via a glass channel 100. Below, we will explain the configuration in which the glass channel 100 attached to the lower end of the glass panel 10 is mounted in the glass groove 17 formed in the lower frame 15. The glass channel 100 attached to the upper end of the glass panel 10 is configured upside down, and the glass channel 100 attached to the end of the glass panel 10 in the width direction is configured rotated 90 degrees, so explanation will be omitted.

[0014] As shown in Figure 3, the bottom frame 15 has a metal frame portion 150 made of metal and a resin frame portion 156 made of resin. The resin frame portion 156 is engaged with the indoor side of the metal frame portion 150. The metal frame portion 150 has a glass groove bottom wall portion 151, an outdoor-side glass groove side wall portion 152, and an indoor-side glass groove side wall portion 153. The bottom frame 15 corresponds to the frame-shaped member in the claims.

[0015] The glass groove bottom wall portion 151 is disposed along the indoor-outdoor direction. The glass groove bottom wall portion 151 corresponds to the bottom of the glass groove 17.

[0016] The outdoor-side glass groove side wall portion 152 extends upward from the outdoor-side end of the glass groove bottom wall portion 151. At the top of the inner surface 152a of the outdoor-side glass groove side wall portion 152 facing the indoor side, a step portion 152b is formed on the underside of the wall portion extending indoors.

[0017] The indoor-side glass groove side wall portion 153 extends upward from the indoor-side end of the glass groove bottom wall portion 151. At the upper part of the inner surface 153a of the indoor-side glass groove side wall portion 153 facing the outdoor side, a step portion 153b is formed on the underside of the wall portion extending to the outdoor side.

[0018] The upper surface 151u of the glass groove bottom wall portion 151, the inner surface 152a of the outdoor-side glass groove side wall portion 152, and the inner surface 153a of the indoor-side glass groove side wall portion 153 form the inner surface of the glass groove 17.

[0019] The glass channel 100 is attached to the outer peripheral edge of the glass panel 10. The glass channel 100 has a substantially U-shaped cross section that opens upward.

[0020] The glass channel 100 has a base portion 21 and a pair of side wall portions 26. The glass channel 100 has a shape that is symmetrical about the center in the groove width direction T1. The following description will be based on the state in which the glass panel 10 is attached to the glass channel 100 and mounted on the lower frame 15. The base portion 21 is arranged along the edge surface 10a of the glass panel 10. The base portion 21 abuts against the edge surface 10a of the glass panel 10.

[0021] The side wall portion 26 extends upward along the plate surface 10b of the glass panel 10 from the end of the base portion 21 facing the indoor / outdoor direction.

[0022] The side wall portion 26 has a first side wall portion 27 and a second side wall portion 28. The first side wall portion 27 extends upward from the indoor / outdoor end of the base portion 21. The lower end of the second side wall portion 28 is connected to the upper end of the first side wall portion 27. The second side wall portion 28 extends upward from the upper end of the first side wall portion 27.

[0023] The glass channel 100 is molded by two-color molding. The base portion 21 and the first side wall portion 27 are molded from a first resin. The second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283 (described later) are molded from a second resin. The hardness of the first resin is higher than that of the second resin. For example, the hardness of the first resin is about 100°, and the hardness of the second resin is about 70°. More specifically, the hardness of the first resin is 90 to 100°, and the hardness of the second resin is 60 to 80°. For example, the first resin is hard polyvinyl chloride, and the second resin is soft polyvinyl chloride.

[0024] In the following description, the direction toward the center of the groove width along the indoor / outdoor direction of the glass groove 17 is referred to as the inside of the groove width direction T1, and the opposite side is referred to as the outside of the groove width direction T1.

[0025] The surface of the first side wall portion 27 facing outward in the groove width direction T1 is referred to as an outer surface 27a. A recess 271 recessed inward in the groove width direction T1 is formed on the outer surface 27a at the middle in the vertical direction of the first side wall portion 27.

[0026] An outer fin portion 272 extending outward in the groove width direction T1 is provided on the outer surface 27a of the first side wall portion 27. The outer fin portion 272 is connected to the lower portion of the recess 271. The outer fin portion 272 is inclined outward with respect to the vertical plane so as to gradually extend outward in the groove width direction T1 as it extends upward. The tip of the outer fin portion 272 provided on the outdoor-side first side wall portion 27 is engaged with the step portion 152b of the outdoor-side glass groove side wall portion 152 of the bottom frame 15. The tip of the outer fin portion 272 provided on the indoor-side first side wall portion 27 is engaged with the step portion 153b of the indoor-side glass groove side wall portion 153 of the bottom frame 15. The outer fin portion 272 is capable of being accommodated inside the recess 271 when it elastically deforms inward in the groove width direction T1.

[0027] The position where the tip of the outer fin portion 272 is engaged with the steps 152b, 153b corresponds to the first position in the claims. The position where the outer fin portion 272 is housed inside the recess 271 corresponds to the second position in the claims.

[0028] An upwardly extending upwardly facing wall portion 152c is provided above the step portion 152b of the outdoor-side glass channel side wall portion 152. An upwardly extending wall portion 153c is provided above the step portion 153b of the indoor-side glass channel side wall portion 153. An upper portion 274 of the first side wall portion 27 extends upward. The upper portion 274 of the outdoor-side first side wall portion 27 abuts against the upwardly facing wall portion 152c of the outdoor-side glass channel side wall portion 152. The upper portion 274 of the indoor-side first side wall portion 27 abuts against the upwardly facing wall portion 153c of the indoor-side glass channel side wall portion 153.

[0029] The surface of the first side wall portion 27 facing inward in the groove width direction T1 is referred to as the inner surface 27b. A first inner fin portion 275 extending inward in the groove width direction T1 is provided on the inner surface 27b of the first side wall portion 27. A base end portion 275a of the first inner fin portion 275 is inclined inward with respect to the vertical plane so as to gradually face inward in the groove width direction T1 as it extends downward. A tip end portion 275b on the tip side of the base end portion 275a of the first inner fin portion 275 faces vertically downward and is pressed against the plate surface 10b of the glass panel 10. The tip end portion 275b of the first inner fin portion 275 that is pressed against the plate surface 10b of the glass panel 10 is located lower, closer to the base end of the side wall portion 26, than the locations where the outer fin portion 272 engages with the step portions 152b, 153b.

[0030] The surface of the second side wall portion 28 facing outward in the groove width direction T1 is referred to as the outer surface 28a. The outer surface 28a of the second side wall portion 28 is provided with a locking protrusion 281 that protrudes outward in the groove width direction T1. The outdoor-side second side wall portion 28 is locked to the upper end of the upward wall portion 152c of the bottom frame 15. The indoor-side second side wall portion 28 is locked to the upper end of the resin frame portion 156 that is locked to the upper end of the upward wall portion 153c of the bottom frame 15.

[0031] The surface of the second side wall portion 28 facing inward in the groove width direction T1 is referred to as the inner surface 28b. A seal piece 282 is provided at the upper end of the inner surface 28b of the second side wall portion 28. The seal piece 282 is inclined inward with respect to the vertical plane so as to gradually move inward in the groove width direction T1 as it extends upward. The seal piece 282 is pressed against the plate surface 10b of the glass panel 10.

[0032] A second inner fin portion 283 extending inward in the groove width direction T1 is provided at the lower end of the inner surface 28b of the second side wall portion 28. The second inner fin portion 283 is located higher than the first inner fin portion 275, closer to the tip end in the extension direction of the side wall portion 26. A base end portion 283a of the second inner fin portion 283 is inclined inward with respect to the vertical plane so as to gradually move inward in the groove width direction T1 as it extends downward. A tip end portion 283b on the tip side of the base end portion 283a of the second inner fin portion 283 faces vertically downward and is pressed against the plate surface 10b of the glass panel 10.

[0033] A protrusion 284 that protrudes inward in the groove width direction T1 is provided on the inner surface 28b of the second side wall portion 28. The protrusion 284 is located slightly above the second inner fin portion 283 and closer to the tip end in the extension direction of the side wall portion 26.

[0034] The deformation of the outer fin portion 272 when the glass channel 100 is attached to the sill 15 will be described. As shown in FIG. 4, with the glass channel 100 attached to the glass panel 10, the outer edge of the glass panel 10 is inserted into the glass groove 17 of the sill 15. The outer fin portion 272 provided on the first side wall 27 on the indoor side comes into contact with the upward wall portion 153c of the sill 15, causing the base end to elastically deform and the tip to be displaced so as to point vertically upward and be accommodated inside the recess 271. As shown in FIG. 3, when the tip of the outer fin portion 272 overcomes the upward wall portion 153c, the base end is elastically deformed so that the tip of the outer fin portion 272 faces outward in the groove width direction T1. As the outer fin portion 272 extends upward, it gradually inclines outward with respect to the vertical plane so as to point outward in the groove width direction T1. The tip of the outer fin portion 272 engages with the step portion 152b of the outdoor-side glass groove side wall portion 152 of the lower frame 15. The outer fin portion 272 provided on the outdoor-side first side wall portion 27 also deforms in the same manner as the outer fin portion 272 provided on the indoor-side first side wall portion 27 shown above, and therefore a description thereof will be omitted.

[0035] In the fitting 1, the hardness of the second resin forming the first inner fin portion 275 and the second inner fin portion 283 of the glass channel 100 is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100, the first inner fin portion 275 and the second inner fin portion 283 do not deform and provide resistance, making the insertion easier.

[0036] Because the first inner fin portion 275 of the glass channel 100 is located on the base end side of the first side wall portion 27, when the outer peripheral end portion of the glass panel 10 is inserted into the glass channel 100, the plate surface 10b of the glass panel 10 abuts the first inner fin portion 275 just before the end face 10a of the glass panel 10 approaches the base portion 21 of the glass channel 100. Compared to when the first inner fin portion 275 is located on the tip end side of the second side wall portion 28 or in the vicinity of the second inner fin portion 283, frictional resistance when inserting the outer peripheral end portion 0 of the glass panel 10 into the glass channel 100 is reduced, allowing for smoother insertion.

[0037] The hardness of the first resin forming the base portion 21 of the glass channel 100 is higher than the hardness of the second resin forming the second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283. As a result, the base portion 21 that holds the outer peripheral edge of the glass panel 10 is less likely to deform when inserted into the glass groove 17, making insertion easier.

[0038] The hardness of the first resin forming the first side wall portion 27 of the glass channel 100 is higher than the hardness of the second resin forming the second side wall portion 28, the outer fin portion 272, the first inner fin portion 275, and the second inner fin portion 283. This reduces the frictional resistance when the first side wall portion 27 comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

[0039] When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17 with the glass channel 100 attached to the outer peripheral edge of the glass panel, the outer fin portion 272 of the glass channel 100 comes into contact with the upward wall portions 152c, 153c of the lower frame 15, elastically deforms so as to face vertically upward, and is accommodated inside the recess 271. This makes it easy to insert the outer fin portion 272 into the glass groove 17 without it interfering with the upward wall portions 152c, 153c of the lower frame 15, etc.

[0040] After the glass channel 100 is attached to the glass groove 17 of the lower frame 15, the outer fin portion 272 is engaged with the step portions 152b, 153b of the glass groove 17. This prevents the glass channel 100 from coming off the glass groove 17 of the lower frame 15 together with the glass panel 10.

[0041] The first inner fin portion 275 and the second inner fin portion 283 of the glass channel 100 are pressed against the plate surface 10b of the glass panel 10. As a result, when a force acts on the glass panel 10 in a direction that causes it to come out of the glass channel 100, the first inner fin portion 275 and the second inner fin portion 283 resist the force in the coming out direction, thereby preventing the glass panel 10 from coming out of the glass channel 100.

[0042] When a force acts on the glass panel 10 in a direction that causes it to come out of the glass channel 100, the tip of the second inner fin portion 283 is pulled by the plate surface 10b of the glass panel 10 and tries to turn back in the direction of the coming out. At this time, the second inner fin portion 283 comes into contact with the protrusion 284 and is prevented from turning back. This makes it possible to prevent the glass panel 10 from coming out of the glass channel 100.

[0043] Second Embodiment Next, an edge holding member for a glass panel according to a second embodiment will be described mainly with reference to Fig. 5. In the description of the embodiment and modified examples shown below, the same members as those described above will be given the same reference numerals, and their description will be omitted.

[0044] 5, the side wall portion 26A of the glass channel 100A has a first side wall portion 27A and a second side wall portion 28A. The first side wall portion 27A extends upward from the indoor / outdoor end of the base portion 21. The lower end of the second side wall portion 28A is connected to the upper end of the first side wall portion 27A. The second side wall portion 28A extends upward from the upper end of the first side wall portion 27A.

[0045] An outwardly recessed portion 22 is formed on the inner surface of the corner between the base portion 21 and the first side wall portion 27A. The thickness of the first side wall portion 27A is thinner than the thickness of the base portion 21. The first side wall portion 27A is inclined outward with respect to the vertical plane so as to gradually move outward in the groove width direction T1 as it extends upward.

[0046] The gray channel 100A is molded by two-color molding. The base portion 21, the first side wall portion 27A, and the outer protrusions 276 and inner protrusions 277 described later are molded from a first resin. The second side wall portion 28A and the second inner fin portion 283 described later are molded from a second resin. The hardness of the first resin is higher than the hardness of the second resin. For example, the hardness of the first resin is about 100°, and the hardness of the second resin is about 70°.

[0047] An outer protrusion 276 protruding upward is provided on the outer surface 27a of the first side wall portion 27A at the middle in the vertical direction. When an upward force is applied to the glass panel 10, the outer protrusion 276 comes into contact with the steps 152b, 153b of the glass groove 17 and is locked therein.

[0048] An inner protrusion 277 is provided on the inner surface 27b of the first side wall portion 27A, protruding inward and downward in the groove width direction T1. The inner protrusion 277 is located lower than the outer protrusion 276, closer to the base end of the side wall portion 26. The inner protrusion 277 abuts against the plate surface 10b of the glass panel 10.

[0049] When the glass channel 100A is attached to the outer peripheral edge of the glass panel 10, the distance A1 between the pair of outer protrusions 276 is longer than the distance A2 between the upward wall portions 152c, 153c of the glass groove 17. When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17, the recessed portions 22 formed at the corners between the base portion 21 and the first side wall portions 27A make the pair of first side wall portions 27A more likely to bend inwardly in the groove width direction T1 and narrow. Pressed by the pair of first side wall portions 27A, the upward wall portions 152c, 153c expand outwardly in the groove width direction T1, and the outer surfaces 27a of the first side wall portions 27A slide along the inner surfaces of the upward wall portions 152c, 153c. When the outer protrusions 276 climb over the upward wall portions 152c, 153c, the pair of first side wall portions 27A expand outwardly in the groove width direction T1 and return to their original state.

[0050] In the fitting 1, the hardness of the second resin forming the second inner fin portion 283 of the glass channel 100A is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27A. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100A, the second inner fin portion 283 does not deform and provide resistance, making the insertion easier.

[0051] A first side wall portion 27A, which is a portion on the base end side of the side wall portion 26A of the glass channel 100A, is provided with a hard inner protrusion 277. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100A, the inner protrusion 277 guides the plate surface 10b of the glass panel 10, making the insertion easier.

[0052] The hardness of the first resin forming the base portion 21 of the glass channel 100A is higher than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. As a result, the base portion 21 that holds the outer peripheral edge of the glass panel 10 is less likely to deform when inserted into the glass groove 17, making it easier to insert.

[0053] The hardness of the first resin forming the first side wall portion 27A of the glass channel 100A is higher than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. This reduces the frictional resistance when the first side wall portion 27A comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

[0054] The rigidity of the first side wall portion 27A is increased by the hard inner protrusions 277 of the glass channel 100A. As a result, the first side wall portion 27A that holds the outer peripheral edge of the glass panel 10 is less likely to deform when inserted into the glass groove 17, making insertion easier.

[0055] When an upward force is applied to the glass panel 10, the outer protrusion 276 of the glass channel 100A comes into contact with and is locked against the steps 152b, 153b of the glass groove 17. As a result, when an upward force is applied to the glass panel 10 in the direction of removing it from the glass channel 100A, the outer protrusion 276 comes into contact with and is locked against the steps 152b, 153b of the glass groove 17, preventing the glass panel 10 from moving upward any further, thereby preventing the glass channel 100A from coming off the glass groove 17 of the lower frame 15 together with the glass panel 10.

[0056] The inner protrusions 277 of the glass channel 100A are formed of a first resin having high hardness, which makes contact with the plate surface 10b of the glass panel 10 to securely hold the glass panel 10 and prevents the glass panel 10 from coming off the glass channel 100A.

[0057] An outwardly recessed recess 22 is formed on the inner surface of the corner between the base 21 and the first side wall 27A of the glass channel 100A. The thickness of the first side wall 27A is thinner than the thickness of the base 21. As a result, after the glass panel 10 is inserted into the glass groove 17 of the lower frame 15, the first side wall 27A of the glass channel 100A spreads outward in the groove width direction T1, and the outer protrusion 276 can reliably spread to a position where it can be engaged with the steps 152b, 153b of the glass groove 17.

[0058] (Variation 1) Next, the edge holding member for a glass panel according to Modification 1 will be described mainly with reference to FIG.

[0059] 6, an inner protrusion 278 that protrudes inward in the groove width direction T1 is provided on the inner surface 27b of the first side wall portion 27B of the glass channel 100B. The inner protrusion 278 is located lower than the outer protrusion 276, closer to the base end of the side wall portion 26. The inner protrusion 278 abuts against the plate surface 10b of the glass panel 10.

[0060] When the glass channel 100B is attached to the outer peripheral edge of the glass panel 10, the distance A1 between the pair of outer protrusions 276 is longer than the distance A2 between the upward wall portions 152c, 153c of the glass groove 17. When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17, the recessed portions 22 formed at the corners between the base portion 21 and the first side wall portions 27B make the pair of first side wall portions 27B more likely to bend inwardly in the groove width direction T1 and narrow. When the outer surfaces 27a of the first side wall portions 27B slide over the inner surfaces of the upward wall portions 152c, 153c and the outer protrusions 276 climb over the upward wall portions 152c, 153c, the pair of first side wall portions 27B expand outwardly in the groove width direction T1 and return to their original state.

[0061] In the fitting 1, the hardness of the second resin forming the second inner fin portion 283 of the glass channel 100B is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27B. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100B, the second inner fin portion 283 does not deform and provide resistance, making the insertion easier.

[0062] A first side wall portion 27B, which is a portion on the base end side of the side wall portion 26A of the glass channel 100B, is provided with a hard inner protrusion 278. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100B, the inner protrusion 278 guides the plate surface 10b of the glass panel 10, making the insertion easier.

[0063] The hardness of the first resin forming the base portion 21 of the glass channel 100B is higher than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. As a result, the base portion 21 that holds the outer peripheral edge of the glass panel 10 is less likely to deform when inserted into the glass groove 17, making it easier to insert.

[0064] The hardness of the first resin forming the first side wall portion 27B of the glass channel 100B is higher than the hardness of the second resin forming the second side wall portion 28A and the second inner fin portion 283. This reduces the frictional resistance when the first side wall portion 27A comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

[0065] The rigidity of the first side wall portion 27B is increased by the hard inner protrusions 278 of the glass channel 100B. As a result, when the glass panel 10 is inserted into the glass groove 17, the first side wall portion 27B that holds the outer peripheral edge of the glass panel 10 is less likely to deform, making the insertion easier.

[0066] The inner protrusions 278 of the glass channel 100B are formed of a first resin having high hardness, which makes contact with the plate surface 10b of the glass panel 10 to securely hold the glass panel 10 and prevents the glass panel 10 from coming off the glass channel 100B.

[0067] (Variation 2) Next, a glass panel edge holding member according to Modification 2 will be described mainly with reference to FIG.

[0068] 7, the side wall 26C of the glass channel 100C has a first side wall 27C and a second side wall 28C. The first side wall 27C is provided with an outer protrusion 276. The second side wall 28C is provided with a locking protrusion 281, a seal piece 282, a second inner fin 283, a protrusion 284, and a third inner fin 285.

[0069] The third inner fin portion 285 is provided at the lower end of the inner surface 28b of the second side wall portion 28. The third inner fin portion 285 is located below the second inner fin portion 283. The third inner fin portion 285 is formed from a second resin having low hardness. A base end portion 285a of the third inner fin portion 285 is inclined inward with respect to the vertical plane so as to gradually move inward in the groove width direction T1 as it extends downward. A tip end portion 285b on the tip side of the base end portion 253a of the third inner fin portion 285 faces vertically downward and is pressed against the plate surface 10b of the glass panel 10.

[0070] When the glass channel 100C is attached to the outer peripheral edge of the glass panel 10, the distance A1 between the pair of outer protrusions 276 is longer than the distance A2 between the upward wall portions 152c, 153c of the glass groove 17. When the outer peripheral edge of the glass panel 10 is inserted into the glass groove 17, the recessed portions 22 formed at the corners between the base portion 21 and the first side wall portions 27C make the pair of first side wall portions 27C more likely to bend inwardly in the groove width direction T1 and narrow. When the outer surfaces 27a of the first side wall portions 27c slide over the inner surfaces of the upward wall portions 152c, 153c and the outer protrusions 276 climb over the upward wall portions 152c, 153c, the pair of first side wall portions 27C expand outwardly in the groove width direction T1 and return to their original state.

[0071] In the fitting 1, the hardness of the second resin forming the second inner fin portion 283 and the third inner fin portion 285 of the glass channel 100C is lower than the hardness of the first resin forming the base portion 21 and the first side wall portion 27C. As a result, when the outer peripheral edge of the glass panel 10 is inserted into the glass channel 100C, the second inner fin portion 283 and the third inner fin portion 285 do not deform and provide resistance, making the insertion easier.

[0072] The hardness of the first resin forming the base portion 21 of the glass channel 100C is higher than the hardness of the second resin forming the second side wall portion 28C, the second inner fin portion 283, and the third inner fin portion 285. As a result, the base portion 21 that holds the outer peripheral edge of the glass panel 10 is less likely to deform when inserted into the glass groove 17, making it easier to insert.

[0073] The hardness of the first resin forming the first side wall portion 27C of the glass channel 100C is higher than the hardness of the second resin forming the second side wall portion 28C, the second inner fin portion 283, and the third inner fin portion 285. This reduces the frictional resistance when the first side wall portion 27C comes into contact with the upward wall portions 152c, 153c of the glass channel 17 during insertion into the glass channel 17, allowing for smooth insertion.

[0074] The first inner fin portion 275 and the third inner fin portion 285 of the glass channel 100C are pressed against the plate surface 10b of the glass panel 10. As a result, when a force acts on the glass panel 10 in a direction that causes it to come out of the glass channel 100C, the first inner fin portion 275 and the third inner fin portion 285 resist the force in the coming out direction, thereby preventing the glass panel 10 from coming out of the glass channel 100C.
