Description

[Technical field]

[0001] The present invention relates to a holder and a vehicle window glass with a holder. [Background technology]

[0002] A vehicle window glass (typically a side glass) attached to a vehicle door can slide up and down using a lifting device arranged inside the door panel. Specifically, the vehicle window glass has a holder that holds the vehicle window glass, is fixed to the lifting device using the holder, and moves up and down by the driving force of the lifting device.

[0004] [Patent Document 1] Patent Publication No. 2022-93828 Summary of the Invention [Problem to be solved by the invention]

[0005] When the holder is made of a resin material, like the holder disclosed in Patent Document 1, the rigidity of the holder is lower than when the holder is made of a metal material. Therefore, in order to increase the rigidity of the holder, it is preferable to make the holder of a metal material.

[0006] However, if the holder is made of a metal material, when the holder is used to hold a vehicle window glass, the highly rigid holder comes into contact with the vehicle window glass, placing a load on the vehicle window glass and causing the vehicle window glass to be damaged.

[0007] The present invention has been made in consideration of the above-mentioned points, and has an object to provide a holder and a vehicle window glass with a holder that can prevent the vehicle window glass from being damaged. [Means for solving the problem]

[0008] A holder according to one embodiment of the present invention is a holder for holding a vehicle window glass, and comprises a main body portion made of a metal material having a bottom, a first side wall portion extending upward from one side of the bottom, and a second side wall portion extending upward from the other side of the bottom, and a buffer portion made of a resin material provided on the inside of the first side wall portion and the second side wall portion, and when the vehicle window glass is placed, the first side wall portion and the second side wall portion of the main body portion are configured to hold the vehicle window glass via the buffer portion.

[0009] A vehicle window glass with a holder according to one aspect of the present invention includes a vehicle window glass and a holder for holding the vehicle window glass. The holder includes a main body made of a metal material including a bottom, a first side wall extending upward from one side of the bottom, and a second side wall extending upward from the other side of the bottom, and a buffer part made of a resin material provided on the inside of the first side wall and the second side wall, and when the vehicle window glass is placed, the first side wall and the second side wall of the main body are configured to be able to hold the vehicle window glass via the buffer part. Effect of the Invention

[0010] According to the present invention, it is possible to provide a holder capable of preventing breakage of a vehicle window glass, and a vehicle window glass with a holder. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a plan view showing an example of a holder-equipped vehicle window glass according to an embodiment. As shown in Fig. 1, the holder-equipped vehicle window glass 1 according to the embodiment includes a vehicle window glass 101 and holders (vehicle window glass holders) 100_1 and 100_2 for holding the vehicle window glass 101. Note that Fig. 1 shows a configuration example in which two holders 100_1 and 100_2 are attached to the vehicle window glass 101, but the number of holders 100 attached to the vehicle window glass 101 may be one or more and can be determined arbitrarily by the user. In addition, in this specification, the holders 100_1 and 100_2 may be collectively referred to as the holder 100.

[0013] In this embodiment, the vehicle window glass 101 may be a single sheet of glass or a laminated glass. In the case of a laminated glass, for example, it can be constructed by sandwiching an intermediate film between two glass sheets. For example, polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) can be used for the intermediate film.

[0014] In this embodiment, a vehicle window glass 101 is held by holders 100_1 and 100_2, and these holders 100_1 and 100_2 are fixed to a lifting device (not shown). The vehicle window glass 101 moves in the vertical direction by the driving force of the lifting device (not shown).

[0015] Next, the holder according to the present embodiment will be described. Fig. 2 is an exploded perspective view showing an example of the holder according to the present embodiment. Fig. 3 is a side view showing an example of the holder according to the present embodiment.

[0016] As shown in FIG. 2, the holder 100 according to the present embodiment includes a main body 10 and a buffer section 20. The main body 10 includes a bottom 11, a first side wall 12 extending from one side (negative side in the y-axis direction) of the bottom 11 toward the upper side (positive side in the z-axis direction), and a second side wall 13 extending from the other side (positive side in the y-axis direction) of the bottom 11 toward the upper side (positive side in the z-axis direction). That is, the main body 10 has a groove 14 having a substantially U-shaped cross section as viewed from the x-axis direction. The main body 10 is made of a metal material. By making the main body 10 of a metal material, the rigidity of the holder 100 can be increased. The main body 10 may be made by assembling a plurality of parts (for example, the bottom 11, the first side wall 12, and the second side wall 13). The main body 10 may also be integrally formed by casting or the like. The metal material constituting the main body 10 may be, for example, stainless steel, aluminum, iron, or the like. The bottom 11 extends to the negative z-axis direction, and the plate-like portion of the bottom 11 on the negative z-axis direction side is fixed to a lifting device (not shown). Note that the approximate U-shape in this specification may have an arc-shaped or linear bottom, and may have a corner at the boundary between the bottom and the side wall.

[0017] 2 and 3, the buffer section 20 is provided on the inside of the first side wall section 12 and the second side wall section 13 of the main body section 10. Specifically, the buffer section 20 is provided so as to follow the bottom section 11, the first side wall section 12 and the second side wall section 13 of the main body section 10. In other words, the buffer section 20 includes a bottom section 21, a first side wall section 22 and a second side wall section 23 so as to correspond to the bottom section 11, the first side wall section 12 and the second side wall section 13 of the main body section 10, respectively, and has a groove having a substantially U-shaped cross section.

[0018] The buffer section 20 is made of a resin material. Examples of the resin material that can be used include thermoplastic elastomer resins such as ethylene propylene diene rubber (EPDM), silicone rubber, olefin-based thermoplastic elastomer (TPO), ABS resin, polyethylene (PE) resin, and polypropylene (PP) resin. The buffer section 20 can be integrally formed by injection molding using these materials.

[0019] As shown in FIG. 3, the buffer section 20 is attached to the groove 14 of the main body section 10 (i.e., inside the first and second side wall sections 12, 13). At this time, the bottom section 21, the first side wall section 22, and the second side wall section 23 of the buffer section 20 are provided so as to abut against the bottom section 11, the first side wall section 12, and the second side wall section 13 of the main body section 10, respectively. When the vehicle window glass 101 is placed in the holder 100, the first and second side wall sections 12, 13 of the main body section 10 hold the vehicle window glass 101 via the first and second side wall sections 22, 23 of the buffer section 20. In other words, the vehicle window glass 101 is placed so as to be sandwiched in the groove of the buffer section 20. For example, the buffer section 20 may be fixed to the main body section 10 using an adhesive member. Also, the vehicle window glass 101 may be fixed to the buffer section 20 using an adhesive member.

[0020] In this embodiment, the main body 10 is made of a metal material. This increases the rigidity of the holder 100, thereby increasing the force (glass support rigidity) for supporting the vehicle window glass 101. In addition, in this embodiment, the buffer section 20 made of a resin material is attached to the groove 14 of the main body 10. This allows the vehicle window glass 101 to be held appropriately. That is, in this embodiment, the buffer section 20 made of a resin material is provided between the main body 10 made of a metal material and the vehicle window glass 101, so that the stress acting from the main body 10 to the vehicle window glass 101 can be alleviated by the buffer section 20. This prevents the vehicle window glass 101 from being damaged.

[0021] Next, another configuration example of the holder according to the present embodiment will be described.

[0022] FIG. 4 is a perspective view showing another example of the buffer portion provided in the holder according to the present embodiment. FIG. 5 is a side view showing another example of the holder according to the present embodiment. The holder 100a shown in FIG. 5 includes a main body portion 10a and a buffer portion 20a.

[0023] In the configuration examples shown in FIGS. 4 and 5, the buffer portion 20a includes a protruding portion 28 that protrudes from the surface of the buffer portion 20a toward the first and second side wall portions 12 and 13. Specifically, the buffer portion 20a includes a protruding portion 28 that protrudes from the surface on the minus side in the y-axis direction of the first side wall portion 22 toward the first side wall portion 12 of the main body portion 10a. Similarly, the buffer portion 20a includes a protruding portion 28 that protrudes from the surface on the plus side in the y-axis direction of the second side wall portion 23 toward the second side wall portion 13 of the main body portion 10a.

[0024] Further, as shown in FIG. 5, the main body portion 10a includes recesses 16 on the inner side surfaces of the first and second side wall portions 12 and 13. In the configuration examples shown in FIGS. 4 and 5, the protruding portion 28 of the buffer portion 20a fits into the recesses 16 of the first and second side wall portions 12 and 13, so that the buffer portion 20a is positioned on the main body portion 10a.

[0025] In the configuration examples shown in FIGS. 4 and 5, the buffer portion 20a includes a first contact portion 27 that contacts the outer side surface (the side surface on the plus side in the x-axis direction) of the main body portion 10a at one end side (the plus side in the x-axis direction) in the direction in which the groove 14 of the main body portion 10a extends. Similarly, the buffer portion 20a includes a second contact portion (not shown in FIG. 5) that contacts the outer side surface (the side surface on the minus side in the x-axis direction) of the main body portion 10a at the other end side (the minus side in the x-axis direction) in the direction in which the groove 14 of the main body portion 10a extends. By providing the first and second contact portions 27 on the buffer portion 20a in this way, the displacement of the buffer portion 20a in the x-axis direction with respect to the main body portion 10a can be restricted.

[0026] Note that FIGS. 4 and 5 show a configuration example including the first and second contact portions 27 and the protruding portion 28. However, in the present embodiment, a configuration including the first and second contact portions 27 or the protruding portion 28 may be employed. That is, the first and second contact portions 27 may be omitted, or the protruding portion 28 may be omitted.

[0027] 6 to 8 are an exploded perspective view, a perspective view, and a side view, respectively, showing another example of the holder according to the present embodiment. The holder 100b shown in FIGS. 6 to 8 includes a main body 10b and a buffer 20b. In the configuration example shown in FIGS. 6 to 8, fitting portions 17 are provided on the outer side surfaces of the first and second side walls 12, 13 of the main body 10b. The buffer 20b includes a member 33 that covers the substantially U-shaped top surface of the main body 10b, and an outer member 34 that extends from the member 33 to the negative side in the z-axis direction. A protrusion 30 is provided on the end of the outer member 34 on the negative side in the z-axis direction.

[0028] The protrusion 30 on the first side wall 22 side of the buffer part 20b and the protrusion 30 on the second side wall part 23 side are each configured to fit into the fitting parts 17 of the first and second side wall parts 12, 13. By configuring the protrusion 30 of the buffer part 20b to fit into the fitting parts 17 of the first and second side wall parts 12, 13 in this manner, the buffer part 20b can be fixed to the main body part 10b.

[0029] 6 to 8, the buffer section 20b includes a member 33 that covers the substantially U-shaped top surface of the main body section 10b. This makes it possible to prevent the vehicle window glass 101 from coming into direct contact with the main body section 10b made of a metal material when the vehicle window glass 101 is attached to the holder 100b. In other words, the member 33 that covers the substantially U-shaped top surface of the main body section 10b serves as a buffer material. Also, in other configuration examples, the member 33 that covers the substantially U-shaped top surface of the main body section may be provided.

[0030] 6 to 8, the outer member 34 of the buffer part 20b is configured to cover the outer side surfaces of the first and second side wall parts 12, 13 of the main body part 10b. Therefore, the outer member 34 of the buffer part 20b can be used to protect the first and second side wall parts 12, 13 of the main body part 10b, and therefore corrosion of the first and second side wall parts 12, 13 can be suppressed.

[0031] 6 to 8, similarly to the configuration examples shown in Figures 4 and 5, the buffer part 20b includes the first and second contact parts 27. This makes it possible to limit the displacement of the buffer part 20b in the x-axis direction relative to the main body part 10b.

[0032] Fig. 9 is a cross-sectional view showing another example of the holder according to the present embodiment. A holder 100c shown in Fig. 9 includes a main body portion 10c and a buffer portion 20c.

[0033] In the configuration example shown in FIG. 9, the first and second side wall portions 22, 23 of the buffer portion 20c each have a hollow portion 31 therein. By providing the hollow portion 31 inside the first and second side wall portions 22, 23 in this way, when the holder 100c holds the vehicle window glass 101, for example, the variation in the plate thickness of the vehicle window glass 101 can be absorbed. That is, by providing the hollow portion 31 inside the first and second side wall portions 22, 23, the amount of displacement of the first and second side wall portions 22, 23 in the y-axis direction can be increased. Therefore, even if there is variation in the plate thickness of the held vehicle window glass 101, the first and second side wall portions 22, 23 are displaced in the y-axis direction, and this variation can be absorbed. In addition, since the amount of displacement of the first and second side wall portions 22, 23 in the y-axis direction can be increased, the stress acting on the vehicle window glass 101 can be further alleviated. Furthermore, the holder 100c can properly hold the vehicle window glass 101 by means of an elastic force generated by the displacement of the first and second side wall portions 22, 23 in the y-axis direction.

[0034] Also, in the configuration example shown in FIG. 9, a curved portion 29 having a predetermined radius of curvature is provided at the plus-side ends of the first and second side wall portions 22 and 23 of the buffer portion 20c in the z-axis direction. When the curved portion 29 is provided in this way, when attaching the vehicle window glass 101 to the holder 100c, it is possible to suppress interference between the holder 100c and the vehicle window glass 101. Therefore, the vehicle window glass 101 can be smoothly attached to the holder 100c. The other configurations are the same as those shown in FIGS. 6 to 8. Also, in other configuration examples, the curved portion 29 may be provided. Note that the curved portion 29 is formed, for example, by chamfering the plus-side ends of the first and second side wall portions 22 and 23 of the buffer portion 20c in the z-axis direction.

[0035] FIG. 10 is a cross-sectional view showing another example of the holder according to the present embodiment. FIG. 11 is a cross-sectional view showing a state in which a vehicle window glass is attached to the holder shown in FIG. 10. The holder 100d shown in FIG. 10 includes a main body portion 10d and a buffer portion 20d.

[0036] In the configuration example shown in FIG. 10, the first and second side wall portions 12 and 13 of the main body portion 10d each include a portion 18 where the inner walls of the first and second side wall portions 12 and 13 are cut away. When the portions 18 where the inner walls of the first and second side wall portions 12 and 13 are cut away are provided in this way, when attaching the buffer portion 20d to the main body portion 10d, gaps are formed between the first and second side wall portions 12 and 13 of the main body portion 10d and the first and second side wall portions 22 and 23 of the buffer portion 20d, respectively.

[0037] As shown in FIG. 11, when the vehicle window glass 101 is disposed on the holder 100d, the first and second side wall portions 22 and 23 of the buffer portion 20d are displaced toward the portion 18 where the inner wall is cut away. That is, by the first and second side wall portions 22 and 23 spreading in the y-axis direction, variations in the plate thickness of the vehicle window glass 101 can be absorbed. Also, since the displacement amount of the first and second side wall portions 22 and 23 in the y-axis direction can be increased, the stress acting on the vehicle window glass 101 can be further relaxed. The other configurations are the same as those shown in FIGS. 6 to 8.

[0038] 12 and 13 are cross-sectional views showing other examples of the buffer section included in the holder according to the present embodiment. Fig. 12 and Fig. 13 show enlarged cross-sectional views of the second side wall section 23 of the buffer section 20. The cross-sectional shape of the first side wall section 22 of the buffer section 20 also has a similar configuration to the second side wall section 23.

[0039] As shown in the left diagrams of Fig. 12 and Fig. 13, in this embodiment, the buffer section 20 may have uneven shapes 38, 39 on the surface on the side that comes into contact with the vehicle window glass 101. In the configuration example shown in Fig. 12, the cross-sectional shape of the convex portions and concave portions that make up the uneven shape 38 is triangular. In addition, in the configuration example shown in Fig. 13, the cross-sectional shape of the convex portions and concave portions that make up the uneven shape 39 is semicircular. Note that in this embodiment, the cross-sectional shape of the uneven shape may be a shape other than the shapes shown in Figs. 12 and 13.

[0040] When the vehicle window glass 101 is attached to the holder having the uneven shapes 38, 39, the uneven shapes 38, 39 of the second side wall portion 23 are compressed and flattened, as shown in the right diagrams of Figures 12 and 13. In this way, when the uneven shapes 38, 39 are formed on the surface of the buffer part 20, the uneven shapes 38, 39 are crushed when the vehicle window glass 101 is pressed in, so that the stress generated in the vehicle window glass 101 can be alleviated.

[0041] At this time, the volume of the convex portions of the uneven shapes 38, 39 of the buffer section 20 may be configured to be smaller than the volume of the concave portions. With this configuration, the vehicle window glass 101 can be easily press-fitted into the holder. That is, when the vehicle window glass 101 is press-fitted into the holder, the convex portions of the uneven shapes 38, 39 are crushed and a part of the member of the convex portions moves to the concave portions, but by making the volume of the convex portions smaller than the volume of the concave portions, it is possible to make it easier for a part of the member of the convex portions to move to the concave portions. Therefore, it is possible to reduce the resistance when the vehicle window glass 101 is press-fitted into the holder, and it is possible to make it easier for the vehicle window glass 101 to be press-fitted into the holder.

[0042] Fig. 14 is a perspective view showing another example of the buffer part provided in the holder according to the present embodiment. Fig. 15 is a perspective view showing the buffer part shown in Fig. 14 attached to a vehicle window glass. Fig. 16 is a perspective view showing the holder according to the present embodiment attached to a vehicle window glass.

[0043] In this embodiment, a buffer section 20e having a shape as shown in Fig. 14 may be used. That is, the buffer section 20e has a bottom section 21, a first side wall section 22, and a second side wall section 23, and is configured so that the space between the bottom section 21 and the first side wall section 22 and the space between the bottom section 21 and the second side wall section 23 can be folded. The buffer section 20e is made of a resin material. An adhesive member 52 is provided on the surface of the first side wall section 22, and an adhesive member 53 is provided on the surface of the second side wall section 23. As the adhesive members 52 and 53, for example, double-sided tape is used.

[0044] As shown in FIG. 15, when attaching the buffer portion 20e to the vehicle window glass 101, the portion between the bottom 21 and the first side wall portion 22, and the portion between the bottom 21 and the second side wall portion 23 of the buffer portion 20e are bent in a valley fold, and the buffer portion 20e is attached to the vehicle window glass 101 using adhesive members 52, 53.

[0045] Thereafter, the main body portion 10e is attached to the vehicle window glass 101 to which the buffer portion 20e has been attached, as shown in Fig. 16. For example, the main body portion 10e and the buffer portion 20e may be bonded together using an adhesive member.

[0046] Fig. 17 is an exploded perspective view showing another example of the holder according to the present embodiment. Fig. 18 is a perspective view showing another example of the holder according to the present embodiment. Fig. 19 is a cross-sectional view taken along line XIX-XIX in Fig. 18. Fig. 20 is a plan view showing another example of the holder according to the present embodiment.

[0047] As shown in FIG. 17, the holder 100f according to this embodiment includes a main body 10f and a buffer 20f. In the configuration example shown in FIGS. 17 to 20, the buffer 20f includes a first buffer member 41 provided at one end (positive side in the x-axis direction) of the main body 10f in the direction in which the groove 14 extends, and a second buffer member 42 provided at the other end (negative side in the x-axis direction). The first buffer member 41 and the second buffer member 42 have a substantially U-shaped cross section as viewed from the x-axis direction. Specifically, the first buffer member 41 and the second buffer member 42 each include a bottom portion extending in the y-axis direction, and two side walls (corresponding to the first side wall portion 22 and the second side wall portion 23 shown in FIG. 2) extending from both sides of the bottom portion in the y-axis direction to the positive side in the z-axis direction.

[0048] The buffer section 20f further includes a first connecting member 43 that connects the first buffer member 41 and the second buffer member 42 on the side of the first side wall section 12, and a second connecting member 44 that connects the first buffer member 41 and the second buffer member 42 on the side of the second side wall section 13. The gap section 45 is provided in a region sandwiched between the first buffer member 41 and the second buffer member 42.

[0049] 18, the buffer portion 20f is attached to the groove 14 of the main body portion 10f (i.e., inside the first and second side wall portions 12, 13). The first and second buffer members 41, 42 are provided so as to abut against the first and second side wall portions 12, 13 of the main body portion 10f, respectively. When the vehicle window glass 101 is placed in the holder 100f, the first and second side wall portions 12, 13 of the main body portion 10f hold the vehicle window glass 101f via the first and second buffer members 41, 42.

[0050] 17 and 18, the buffer portion 20f is provided with the gap portion 45, which reduces the contact area between the buffer portion 20f and the vehicle window glass 101. This reduces the resistance acting between the buffer portion 20f and the vehicle window glass 101 when the vehicle window glass 101 is press-fitted into the holder 100f, which makes it easier to press the vehicle window glass 101 into the holder 100f.

[0051] In the configuration example shown in Figs. 17 to 20, the adhesive member 80 that bonds the vehicle window glass 101 to the first and second side wall portions 12 and 13 can be filled in the gap 45. In this case, the adhesive member can be sufficiently filled between the vehicle window glass 101 and the holder 100f, so that the vehicle window glass 101 and the holder 100f can be firmly fixed. As shown in Figs. 19 and 20, the gap 45_1 on the first side wall portion 12 side is formed in an area surrounded by the first side wall portion 12, the first buffer member 41, the second buffer member 42, the first connecting member 43, and the vehicle window glass 101. Similarly, the gap 45_2 on the second side wall portion 13 side is formed in an area surrounded by the second side wall portion 13, the first buffer member 41, the second buffer member 42, the second connecting member 44, and the vehicle window glass 101.

[0052] The adhesive member 80 is filled in the gap 45_1 on the first side wall portion 12 side and the gap 45_2 on the second side wall portion 13 side. As a result, the first side wall portion 12 and the vehicle window glass 101 are bonded via the adhesive member 80. Also, the second side wall portion 13 and the vehicle window glass 101 are bonded via the adhesive member 80. Furthermore, in this embodiment, as shown in FIG. 19, the adhesive member 80 can be filled on the bottom surface of the vehicle window glass 101. As a result, the bottom 11 of the main body portion 10f and the bottom surface of the vehicle window glass 101 are bonded via the adhesive member 80. Also, as shown in FIG. 20, when the adhesive member 80 is filled so as to contact the first and second buffer members 41 and 42, the buffer portion 20f is fixed to the vehicle window glass 101. For example, an epoxy-based or urethane-based adhesive is used as the adhesive member 80. In addition, although Figures 19 and 20 show a configuration example in which some voids 45 remain after filling with adhesive material 80, in this embodiment, adhesive material 80 may be filled in such a way that no voids 45 remain.

[0053] 21 to 23 are cross-sectional views showing examples of the configuration of a vehicle window glass held by the holder according to the present embodiment. FIG. 21 to FIG. 23 show examples of the configuration of laminated glass. A vehicle window glass 101a shown in FIG. 21 includes two glass plates 110a, 111a and an intermediate film 112, and the two glass plates 110a, 111a are bonded to each other using the intermediate film 112. In the present embodiment, when the vehicle window glass 101a is placed in a vehicle, the glass plate 110a is the vehicle exterior glass plate, and the glass plate 111a is the vehicle interior glass plate. For example, polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) can be used for the intermediate film 112. The intermediate film 112 may have either a single layer structure or a multiple layer structure.

[0054] The two glass plates 110a, 111a are inorganic glass. Examples of inorganic glass include soda lime glass and aluminosilicate glass. The inorganic glass may be either unstrengthened glass or tempered glass. Unstrengthened glass is made by forming molten glass into a plate shape and slowly cooling it. Tempered glass is made by forming a compressive stress layer on the surface of unstrengthened glass. The tempered glass may be either physically strengthened glass (for example, air-cooled tempered glass) or chemically strengthened glass.

[0055] Although not shown, the two glass sheets 110a, 111a are formed to be convex toward the outside of the vehicle. Gravity forming, press forming, or the like is used for bending the glass sheets. In bending, the uniformly heated glass sheet may be rapidly cooled from a temperature near its softening point, and compressive stress may be generated on the glass surface due to the temperature difference between the glass surface and the inside of the glass, thereby physically strengthening the glass surface. After bending, the glass surface may be chemically strengthened by generating compressive stress on the glass surface by an ion exchange method or the like.

[0056] The thickness of the vehicle window glass 101a is preferably 2.8 mm to 10 mm, and more preferably 3.0 mm to 8.0 mm. When the thickness of the vehicle window glass 101a is 2.8 mm to 10 mm, it is possible to ensure sufficient transmittance as a vehicle window glass and sufficient rigidity. Here, if the vehicle window glass 101a having a thickness of 6.0 mm or less is used as glass for a frameless door, there is a risk that the window glass will bend when the door is opened or closed, for example. In contrast, the vehicle window glass with holder according to the present embodiment has a high glass supporting rigidity of the holder and can suppress bending of the window glass, so it is suitable for glass for a frameless door having a thickness of 6.0 mm or less.

[0057] The thickness of the glass plate 110a is preferably 1.1 mm to 3.6 mm, and more preferably 1.8 mm to 3.0 mm. When the thickness of the glass plate 110a is 1.1 mm to 3.6 mm, the weight of the vehicle window glass can be reduced and sufficient strength can be ensured. The thickness of the glass plate 111a is preferably 0.5 mm to 2.7 mm, and more preferably 0.5 mm to 2.3 mm. When the thickness of the glass plate 111a is 0.5 mm to 2.7 mm, the weight of the vehicle window glass can be reduced and the handleability of the glass plate 111a can be maintained good.

[0058] The thickness of the interlayer 112 is preferably 0.5 mm to 3.0 mm, and more preferably 0.5 mm to 2.8 mm. When the thickness of the interlayer 112 is 0.5 mm to 3.0 mm, it is possible to reduce the weight of the vehicle window glass and ensure sufficient impact resistance.

[0059] The vehicle window glass with holder, which includes the vehicle window glass 101a and a holder for holding the vehicle window glass 101a, is suitable for use as glass for frameless doors because the holder has high glass supporting rigidity, and therefore the window glass is less likely to bend when the door is opened or closed.

[0060] As shown in Fig. 22 and Fig. 23, in this embodiment, the vehicle window glass may have a shape in which the portion held by the holder bulges toward at least one of the first side wall portion 12 and the second side wall portion 13. That is, as in the vehicle window glass 101b shown in Fig. 22, the lower side of the glass plate 110b may be configured to bulge toward the negative side in the y-axis direction and the positive side in the y-axis direction. Also, as in the vehicle window glass 101c shown in Fig. 23, the lower side of one of the two glass plates 110c, 111c, bulges toward the negative side in the y-axis direction. Note that the lower side of the intermediate film 112 may be configured to bulge in the y-axis direction, similar to the lower sides of the glass plates 110b, 111b, and 110c.

[0061] By forming at least one of the two glass plates constituting the vehicle window glass in such a way that it bulges outward, the glass supporting rigidity when the vehicle window glass is held by the holder can be increased.

[0062] Although the present invention has been described above in accordance with the above-described embodiment, the present invention is not limited to the configuration of the above-described embodiment, and naturally includes various modifications, alterations, or combinations that a person skilled in the art could make within the scope of the invention of the claims of the present application.
