[0004] [Patent Document 1] JP 2010-83397 A [Patent Document 2] Patent No. 6120012 Summary of the Invention [Problem to be solved by the invention]

[0005] The problem to be solved by the present invention will be described with reference to Figs. 9 to 11. Fig. 9 is a diagram for explaining the problem to be solved by the present invention, showing a side view of a vehicle (automobile). Figs. 10 and 11 are perspective views for explaining a vehicle window glass according to the prior art. As shown in Fig. 9, a door panel 105 of a vehicle 100 is provided with a side glass 106 and a front bench glass 101. The front bench glass 101 is a fixed window having a substantially triangular shape, and is fixed to the front of the door panel 105. The front bench glass 101 is sometimes called a front corner glass.

[0006] 10, a front bench glass 101 (vehicle window glass) includes a glass plate 110 and a resin molding 111 provided on the peripheral edge of the glass plate 110. The front bench glass 101 is attached to a door panel 105 via the resin molding 111. At this time, a molding lower portion 113 of the resin molding 111 that is disposed on the lower side of the vehicle window glass 101 is disposed inside the door panel 105.

[0007] When the front bench glass 101 is attached to the door panel 105, a gap may be formed at the attachment point between the front bench glass 101 and the door panel 105. In particular, when a gap is formed in the front portion 118 of the front bench glass 101, wind will enter through this gap during driving. As shown in FIG. 10, this entering wind passes through the lower part 113 of the molding below the front bench glass 101 and enters the inside of the door panel 105. When wind enters the inside of the door panel 105 in this way, there is a problem in that abnormal noise is generated due to the entering wind.

[0008] In the prior art, to solve such problems, a damping member 115 for damping the flow of wind is provided on a lower part 113 of the molding below the front bench glass 101, as shown in Fig. 11. For example, an EPDM sealer (sponge) or the like is used for the damping member 115. However, when the damping member 115 is provided in this way, there is a problem that the cost increases because of the material cost of the damping member 115 and the labor required to attach the damping member 115 to the lower part 113 of the molding.

[0009] In view of the above problems, an object of the present invention is to provide a vehicle window glass that can, at low cost, suppress the generation of abnormal noise caused by wind that has entered the gap that occurs at the attachment point between a resin-framed glass plate and a door panel. [Means for solving the problem]

[0010] A vehicle window glass according to one aspect of the present invention is a vehicle window glass used as a fixed window of a vehicle, and comprises a glass plate and a resin molding provided on the peripheral edge of the glass plate, wherein a lower part of the molding arranged on the underside of the vehicle window glass is configured to be positioned inside the door panel when the vehicle window glass is attached to the door panel, and a plate-shaped member protruding to the outside of the vehicle is provided on the lower part of the molding.

[0012] In the vehicle window glass described above, a plurality of the plate-shaped members may be provided in the cavity.

[0013] In the above-mentioned vehicle window glass, the rigidity of the plate-shaped member located furthest forward in the fore-and-aft direction of the vehicle among the plurality of plate-shaped members may be higher than the rigidity of the plate-shaped member located rearward of the forward-most plate-shaped member.

[0014] In the above vehicle window glass, the plate-shaped member may have a thickness of 0.5 mm or more and 8 mm or less.

[0015] In the above-mentioned vehicle window glass, when the vehicle window glass is attached to the door panel, the lower part of the molding may be attached to the door panel via a belt molding attached to the door panel, and the plate-like member may be configured to be spaced apart from a vertical lower end of the belt molding inside the door panel.

[0016] In the above-mentioned vehicle window glass, when the vehicle window glass is attached to the door panel, the lower part of the molding may be attached to the door panel via a belt molding attached to the door panel, and the plate-like member may be configured to abut against a vertical lower end of the belt molding inside the door panel.

[0017] In the above-mentioned vehicle window glass, when the vehicle window glass is attached to the door panel, the lower part of the molding may be attached to the door panel via a belt molding, and a plate-shaped member located most forward in the fore-and-aft direction of the vehicle may be configured to be separated from a vertical lower end of the belt molding inside the door panel, and a plate-shaped member located rearward of the foremost plate-shaped member in the fore-and-aft direction of the vehicle may be configured to abut against a vertical lower end of the belt molding inside the door panel.

[0018] In the above-mentioned vehicle window glass, the surface pressure when the plate-shaped member abuts against the lower end of the belt molding in the vertical direction is 1 to 10 (N / 100 mm 2 ) may also be used.

[0019] In the above vehicle window glass, the plate-shaped member may have an angle of 0 degrees or more and 45 degrees or less with respect to the vertical direction.

[0020] In the above-mentioned vehicle window glass, the resin molding and the plate-like member may be an integrally molded product.

[0021] In the above-mentioned vehicle window glass, the glass plate, the resin molding, and the plate-like member may be an integrally molded product. Effect of the Invention

[0022] The present invention can provide a vehicle window glass that can reduce, at low cost, the generation of abnormal noise caused by wind entering a gap that occurs at the attachment location between a resin-framed glass plate and a door panel. [Brief description of the drawings]

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view for explaining a vehicle window glass according to an embodiment. As shown in Fig. 1, a vehicle window glass 1 according to the present embodiment includes a glass plate 10 and a resin molding 11 provided on the periphery of the glass plate 10. Such a resin-framed glass plate is also called MAW (Module Assy Window: registered trademark). The vehicle window glass 1 according to the present embodiment is a vehicle window glass used for a fixed window of a vehicle, and is suitably used for fixed windows such as a front bench glass or a rear quarter glass of an automobile, for example.

[0025] In the vehicle window glass 1 shown in FIG. 1, the glass plate 10 is formed in a substantially triangular shape in a plan view. However, the shape of the glass plate 10 is not limited to a substantially triangular shape, and may be a substantially rectangular shape, etc. The glass plate 10 may be inorganic glass or organic glass. As the inorganic glass, for example, soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, quartz glass, etc. are used without any particular limitation. Among these, soda-lime glass is particularly preferable from the viewpoint of manufacturing cost and formability. The forming method of the glass plate 10 is not particularly limited. For example, in the case of inorganic glass, a glass plate formed by a float method or the like is preferable.

[0026] When the glass plate 10 is inorganic glass, the glass plate 10 may be either untempered glass or tempered glass. Untempered glass is obtained by forming molten glass into a plate shape and slowly cooling it. Tempered glass is obtained by forming a compressive stress layer on the surface of untempered glass, and may be either air-cooled tempered glass or chemically tempered glass.

[0027] When the tempered glass is physically tempered glass (for example, air-cooled tempered glass), the glass surface may be strengthened by generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the inside of the glass by an operation other than slow cooling, such as rapidly cooling a glass plate uniformly heated in bending from a temperature near the softening point. When the tempered glass is chemically tempered glass, the glass surface may be strengthened by generating a compressive stress on the glass surface by an ion exchange method or the like after bending. In addition, glass that absorbs ultraviolet rays or infrared rays may be used as the glass plate 10. The glass plate 10 is preferably transparent, but may be a glass plate that is colored to the extent that transparency is not impaired.

[0028] The glass sheet 10 may have a curved shape such that the outer side of the vehicle is convex when the glass sheet 10 is attached to the vehicle. The glass sheet 10 may have a single curved shape bent in only one direction, or may have a complex curved shape bent in two directions (for example, a predetermined direction and a direction perpendicular to the predetermined direction). Gravity forming, press forming, roller forming, or the like is used for bending the glass sheet 10. When the glass sheet 10 is bent to a predetermined curvature, the radius of curvature of the glass sheet 10 may be 1000 to 100000 mm.

[0029] The glass plate 10 may be a single glass plate, or may be, for example, laminated glass in which two or more glass plates are bonded together via an interlayer film. As the interlayer film of the laminated glass, for example, a known thermoplastic resin film such as polyvinyl butyral (PVB) or ethylene vinyl acetate copolymer (EVA) is used. The interlayer film of the laminated glass may be transparent or may be a colored interlayer film. The interlayer film may be two or more layers.

[0030] When the glass plate 10 is a laminated glass, the thickness of the glass located on the outside and the thickness of the glass located on the inside when the glass plate 10 is attached to a vehicle may be the same or different. When the glass plate 10 is attached to a vehicle, the thickness of the glass located on the outside is preferably 1.0 mm or more and 3.0 mm or less. When the thickness of the glass plate located on the outside is 1.0 mm or more, the strength such as flying stone resistance performance is sufficient, and when it is 3.0 mm or less, the mass of the laminated glass does not become too large, which is preferable in terms of fuel efficiency of the vehicle. The thickness of the glass plate located on the inside is preferably 0.3 mm or more and 2.3 mm or less. When the thickness of the glass plate located on the inside of the vehicle is 0.3 mm or more, the handling property is good, and when it is 2.3 mm or less, the mass does not become too large. If the thickness of the glass located on the outside and the thickness of the glass located on the inside are each 1.8 mm or less, it is preferable that the glass plate 10 can be both lightweight and soundproof. In addition, when the thickness of the glass located on the inside is 1.0 mm or less, the glass located on the inside may be chemically strengthened glass. When the glass located on the inside is chemically strengthened glass, it is preferable that the compressive stress value of the glass surface is 300 MPa or more, and the depth of the compressive stress layer is 2 μm or more.

[0031] When the glass plate 10 is a single glass plate, the glass plate 10 is preferably air-cooled tempered glass, and in this case, the thickness of the glass plate 10 is preferably 1.0 mm or more and 5.0 mm or less.

[0032] Furthermore, when the glass plate 10 is made of organic glass, examples of the material for the organic glass include transparent resins such as polycarbonate and acrylic resins (for example, polymethyl methacrylate).

[0033] The glass plate 10 may have a shielding layer on the periphery of the surface on the vehicle interior side. The shielding layer is formed, for example, by applying a ceramic color paste containing a fusible glass frit containing a black pigment and then firing it. This can prevent the adhesive applied to the glass plate 10 from being deteriorated by ultraviolet rays. Note that various appropriate films may be formed on the main surface of the glass plate 10 from the viewpoint of improving weather resistance and functionality such as hydrophilicity and water repellency.

[0034] As an example, the resin molding 11 is provided so as to surround the periphery of the glass plate 10. Examples of materials for the molding 11 include synthetic resins such as polyvinyl chloride (PVC) and thermoplastic elastomer (TPE). The molding 11 may be provided around the periphery of the glass plate 10 by mounting the glass plate 10 in a mold having a cavity corresponding to the shape of the molding 11 and injecting the above-mentioned synthetic resin (molten synthetic resin) into the cavity. Alternatively, the resin molding 11 formed separately from the glass plate 10 may be fitted to the outer periphery of the glass plate 10.

[0035] It should be noted that the shape of the vehicle window glass 1 shown in FIG. 1 is just one example, and in this embodiment, the vehicle window glass may have a shape other than that shown in FIG.

[0036] Fig. 2 is a cross-sectional view for explaining a vehicle window glass according to the present embodiment. The cross-sectional view shown in Fig. 2 corresponds to a cross-sectional view of the vehicle window glass 1 taken along the line II-II in Fig. 1, and is a cross-sectional view seen from the front side of the vehicle. The cross-sectional view shown in Fig. 2 shows a state in which the vehicle window glass 1 is attached to a door panel 40.

[0037] 2, the molding lower portion 13 of the molding 11, which is disposed under the vehicle window glass 1, is disposed inside the door panel 40 when the vehicle window glass 1 is attached to the door panel 40. At this time, the molding lower portion 13 is attached to the door panel 40 via a belt molding 45 that is attached to the door panel 40.

[0038] Specifically, as shown in Fig. 2, the door panel 40 includes an outer panel 41, an inner panel 42, a door trim 43, and a belt molding 45. The lower end of the molding 11 (the lower end of the molding lower part 13) of the vehicle window glass 1 is disposed so as to abut against the upper surface of the inner panel 42. Also, the side surface of the molding lower part 13 on the vehicle interior side is disposed so as to abut against the door trim 43. The outer panel 41 is disposed on the outside of the vehicle, and the belt molding 45 is disposed between the molding lower part 13 and the outer panel 41.

[0039] As described above, when the vehicle window glass 1 (front bench glass) is attached to the door panel 40, a gap may be formed at the attachment point between the vehicle window glass 1 and the door panel 40 (see reference numeral 118 in FIG. 9). When a gap (see reference numeral 118 in FIG. 9) is formed at the attachment point between the vehicle window glass 1 and the door panel 40, wind will enter through this gap while the vehicle is traveling. This intruding wind passes through the lower molding 13 of the vehicle window glass 1 and enters the inside of the door panel 40. When wind enters the inside of the door panel 40 in this way, there is a problem in that abnormal noise is generated due to the intruding wind.

[0040] In this embodiment, the lower molding portion 13 disposed inside the door panel 40 is provided with a plate-like member 21 protruding toward the outside of the vehicle so as to attenuate or block wind (indicated by an arrow in FIG. 1) entering the inside of the door panel 40 during driving. That is, as shown in FIG. 2, the plate-like member 21 attenuates or blocks wind entering a cavity between the lower molding portion 13 disposed inside the door panel 40 and the outer panel 41, which is the outer door panel. In this embodiment, since the plate-like member 21 is provided in this manner, wind entering the inside of the door panel 40 can be attenuated or blocked, and abnormal noise can be suppressed. For example, the plate-like member 21 may be provided so as to be approximately perpendicular to the direction of the entering wind, that is, the front-rear direction of the vehicle (the traveling direction of the vehicle). In addition, the plate-like member 21 may be angled so as to follow the trajectory when the lower molding portion 13 is inserted inside the door panel 40. In this case, the plate-like member 21 may be rotated by a predetermined angle around a rotation axis in the height direction of the vehicle.

[0041] As shown in FIG. 2, the plate-like member 21 may be configured to be spaced apart from the vertical lower end 46 of the belt molding 45. The plate-like member 21 may also be configured to abut against the vertical lower end 46 of the belt molding. When the plate-like member 21 is configured to abut against the vertical lower end 46 of the belt molding, it is possible to more reliably attenuate or block wind that has entered the interior of the door panel 40. For example, the surface pressure when the plate-like member 21 abuts against the vertical lower end 46 of the belt molding 45 is 1 to 10 (N / 100 mm 2 ), preferably 3 to 5 (N / 100 mm 2 When the plate-like member 21 comes into contact with the lower end 46 of the belt molding 45, the plate-like member 21 may be curved in order to adjust the surface pressure with the lower end 46 of the belt molding 45.

[0042] The plate-like member 21 can be formed using a resin. For example, the plate-like member 21 may be an integrally molded product integrally molded with the resin molding 11. That is, the molding 11 including the plate-like member 21 can be formed by integrally molding the glass plate 10 and the resin molding 11 by injection molding using a mold having a shape corresponding to the plate-like member 21. Also, for example, the glass plate 10 and the plate-like member 21 may be disposed between an upper mold and a lower mold of a mold, and a molten resin material may be filled in a cavity space formed by the upper mold and the lower mold, and the resin material may be solidified to form a vehicle window glass 1 including the plate-like member 21. That is, the vehicle window glass 1 may be an integrally molded product composed of the glass plate 10, the resin molding 11, and the plate-like member 12. Also, for example, the vehicle window glass 1 may be a two-color molded product in which the resin molding 11 is integrally molded by injection molding, and then a resin different from the resin molding 11 is injection molded to form the plate-like member 21. The same applies to the manufacturing methods of the vehicle window glasses 1a and 1b described below.

[0043] In this embodiment, since the plate-like member 21 is provided on the resin molding 11 in this manner, the plate-like member 21 can be formed at low cost. In particular, when the resin molding 11 and the plate-like member 21 are formed as an integrally molded product, the plate-like member 21 can be formed at low cost. Therefore, the invention according to this embodiment can provide a vehicle window glass that can suppress, at low cost, the generation of abnormal noise caused by wind entering a gap that occurs at the attachment location between the resin-framed glass plate and the door panel.

[0044] FIG. 3 is a perspective view for explaining a vehicle window glass according to this embodiment. As shown in FIG. 3, in this embodiment, a plurality of plate-like members 21-25 may be provided on the lower part 13 of the molding arranged on the lower side of the vehicle window glass 1a. The plurality of plate-like members 21-25 are provided so as to be aligned from the upstream side (the front side in the longitudinal direction of the vehicle) to the downstream side (the rear side in the longitudinal direction of the vehicle) of the wind that enters during driving. In this way, when a plurality of plate-like members 21-25 are provided, the wind that enters the inside of the door panel 40 can be more reliably attenuated or blocked, and the generation of abnormal noise can be more effectively suppressed. The thickness of the plate-like members 21-25 may be 0.5 mm or more and 8.0 mm or less.

[0045] In this case, among the multiple plate-like members 21-25, the rigidity of the plate-like member 21 located on the most upstream side of the wind that invades during traveling may be made higher than the rigidity of the plate-like members 22-25 located downstream of the plate-like member 21 located on the most upstream side. In other words, the rigidity of the plate-like member 21 located on the most forward side in the front-rear direction of the vehicle may be made higher than the rigidity of the plate-like members 22-25 located behind the plate-like member 21 in the front-rear direction of the vehicle. In this configuration, the strongest wind can be received by the plate-like member 21 with the strongest rigidity, and then the weaker wind can be attenuated or blocked by the second and subsequent plate-like members 22-25.

[0046] For example, by making the thickness of plate-shaped member 21 thicker than the thicknesses of plate-shaped members 22 to 25, the rigidity of plate-shaped member 21 can be made higher than the rigidity of plate-shaped members 22 to 25. For example, the thickness of plate-shaped member 21 may be 3.0 mm or more and 8.0 mm or less, and the thickness of plate-shaped members 22 to 25 may be 0.5 mm or more and 5.0 mm or less.

[0047] Further, the material constituting the plate-like member 21 may be a material having higher rigidity than the material constituting the plate-like members 22 to 25. In this case, for example, the glass sheet 10, the plate-like member 21 having high rigidity, and the plate-like members 22 to 25 having lower rigidity than the plate-like member 21 are arranged between the upper and lower dies of a molding die. Then, a molten resin material is filled into a cavity space formed by the upper and lower dies, and the resin material is solidified. This makes it possible to integrally mold the resin molding 11 including the plate-like member 21 having high rigidity and the plate-like members 22 to 25 having low rigidity. That is, the vehicle window glass 1a may be an integrally molded product in which the glass sheet 10, the resin molding 11, the plate-like member 21 having high rigidity, and the plate-like members 22 to 25 having low rigidity are integrally molded. The vehicle window glass 1a may be a two-color molded product in which the resin molding 11 is integrally molded on the glass plate 10 by injection molding, and then the plate-like member 21 with high rigidity and the plate-like members 22 to 25 with low rigidity are molded.

[0048] In addition, in the vehicle window glass 1a shown in FIG. 3, the plate-like member 21 located on the most upstream side (the most forward in the front-rear direction of the vehicle) may be configured to be separated from the lower end 46 of the belt molding 45 in the vertical direction (see FIG. 2). In addition, the plate-like members 22 to 25 located on the downstream side (rear of the plate-like member 21 located on the most forward in the front-rear direction of the vehicle) may be configured to abut against the lower end 46 of the belt molding 45 in the vertical direction (see FIG. 4). When the plate-like members 22 to 25 abut against the lower end 46 of the belt molding, the plate-like members 22 to 25 may be curved to adjust the surface pressure with the lower end 46 of the belt molding 45. Note that, although FIG. 4 illustrates a case where the plate-like member 22 and the belt molding 45 abut against each other, the same applies to the other plate-like members 23 to 25.

[0049] That is, the rigidity of the plate member 21 located on the most upstream side is higher than the rigidity of the other plate members 22 to 25. Therefore, when the plate member 21 having high rigidity comes into contact with the lower end 46 of the belt molding 45, there is a possibility that the belt molding 45 will be deformed. For this reason, it is preferable to configure the plate member 21 located on the most upstream side so as to be separated from the lower end 46 of the belt molding 45.

[0050] On the other hand, since the rigidity of the downstream plate-like members 22-25 is lower than that of the plate-like member 21, even if the plate-like members 22-25 having low rigidity abut against the lower end 46 of the belt molding 45, the belt molding 45 can be prevented from being significantly deformed. When the plate-like members 22-25 are configured to abut against the lower end 46 of the belt molding 45, the gap between the plate-like members 22-25 and the belt molding 45 can be reduced, and the wind that has entered the inside of the door panel 40 can be more reliably attenuated or blocked. That is, the plate-like member 21 having high rigidity functions as a plate-like member for reducing the amount of wind (for attenuation), and the plate-like members 22-25 having low rigidity function as plate-like members for reducing the sound heading toward the inside of the vehicle (for sealing).

[0051] For example, the surface pressure when the plate-like members 22 to 25 come into contact with the lower end 46 of the belt molding 45 in the vertical direction is 1 to 10 (N / 100 mm 2 ), preferably 3 to 5 (N / 100 mm 2). The thickness of the plate-like members 21 to 25 (i.e., the thickness in the front-rear direction of the vehicle) is 0.5 mm to 8 mm, and preferably 1 mm to 3 mm. In this case, the thickness of the plate-like member 21 may be made thicker than the thicknesses of the plate-like members 22 to 25, so that the rigidity of the plate-like member 21 is higher than the rigidity of the plate-like members 22 to 25.

[0052] FIG. 5 is a perspective view for explaining a vehicle window glass according to this embodiment. In the configuration shown in FIG. 5, a plurality of plate-shaped members 31-35 are provided on a molding lower portion 13 disposed on the lower side of a vehicle window glass 1b. In addition, in the vehicle window glass 1b shown in FIG. 5, each of the plate-shaped members 31-35 is configured to have an angle of 0 degrees or more and 45 degrees or less with respect to the vertical direction so that when wind entering during driving collides with the plate-shaped members 31-35, the colliding wind is directed toward the lower side of the vehicle (see the arrow in FIG. 5). With this configuration, the entering wind can be actively guided toward the lower side of the vehicle, and abnormal noise can be effectively suppressed from being transmitted to passengers inside the vehicle. The other configurations of the plate-shaped members 31-35 are the same as those of the plate-shaped members 21-25 shown in FIG. 3.

[0053] 3 and 5 show configuration examples in which five plate-like members 21 to 25 and 31 to 35 are provided, respectively. However, in this embodiment, the number of plate-like members provided on the vehicle window glass is not limited to five and can be determined arbitrarily.

[0054] Next, other configuration examples of the vehicle window glass according to this embodiment will be further described. Figures 6 to 8 are perspective views and cross-sectional views for explaining other configuration examples of the vehicle window glass according to this embodiment. Figures 1 to 5 explain configuration examples in which the vehicle window glass 1 is attached to the door panel 40 via the belt molding 45, but Figures 6 to 8 explain configuration examples in which the vehicle window glass is attached to the door panel 40 without using the belt molding 45.

[0055] The vehicle window glass 2 shown in Fig. 6 comprises a glass plate 10 and a resin molding 51 provided on the peripheral edge of the glass plate 10. A lower molding portion 53 of the molding 51 that is disposed below the vehicle window glass 2 is provided with plate-like members 61, 62. Further, an extension portion 55 extending from the lower molding portion 53 to the vehicle exterior side is provided on the vehicle exterior side of the lower molding portion 53 of the vehicle window glass 2. The extension portion 55 is formed integrally with the resin molding 51.

[0056] 7 and 8 are cross-sectional views of the vehicle window glass 2 taken along the cutting lines VII-VII and VIII-VIII in Fig. 6, respectively, as viewed from the front side of the vehicle. The cross-sectional views of Fig. 7 and Fig. 8 show a state in which the vehicle window glass 2 is attached to a door panel 40.

[0057] As shown in Figs. 7 and 8, the molding lower part 53 disposed on the lower side of the vehicle window glass 2 is disposed inside the door panel 40 when the vehicle window glass 2 is attached to the door panel 40. Specifically, as shown in Figs. 7 and 8, the door panel 40 includes an outer panel 41, an inner panel 42, and a door trim 43. The lower end of the molding 51 of the vehicle window glass 2 (the lower end of the molding lower part 53) is disposed so as to abut against the upper surface of the inner panel 42. In addition, the side surface of the molding lower part 53 on the vehicle interior side is disposed so as to abut against the door trim 43. The outer panel 41 is disposed on the outside of the vehicle.

[0058] 7 and 8, the extension 55 of the lower molding part 53 is extended toward the vehicle exterior to cover the upper end of the door panel 40 (outer panel 41). With this configuration, the upper end of the door panel 40 can be hidden, improving the design. In addition, the vehicle window glass 2 can be attached to the door panel 40 without using a belt molding, reducing the number of parts.

[0059] 7 and 8, plate-like members 61 and 62 are provided on molding lower portion 53 disposed inside door panel 40. Plate-like members 61 and 62 are formed so as to protrude from molding lower portion 53 toward the vehicle exterior. In the configuration example shown in FIG. 7 and FIG. 8, the ends of plate-like members 61 and 62 on the vehicle exterior side are formed so as to abut against outer panel 41. The vertical length of plate-like member 61 shown in FIG. 7 is configured to be shorter than the vertical length of plate-like member 62 shown in FIG. 8. In other words, the area of ​​plate-like member 61 shown in FIG. 7 is larger than the area of ​​plate-like member 62 shown in FIG. 8.

[0060] 6 shows an example in which large-area plate-shaped members 61 and small-area plate-shaped members 62 are alternately arranged from the front to the rear of the vehicle. However, the arrangement of the plate-shaped members 61, 62 is not limited to this arrangement and may be any arrangement.

[0061] In the configuration examples shown in Figs. 6 to 8, the plate-like members 61, 62 also attenuate or block wind that penetrates into a cavity between the molding lower portion 53 disposed inside the door panel 40 and the outer panel 41, which is the outer door panel. This makes it possible to suppress the generation of abnormal noise caused by wind that penetrates into a gap that occurs at the attachment location between the resin-framed glass sheet and the door panel. Also in this embodiment, since the plate-like members 61, 62 are provided on the resin molding 51, the plate-like members 61, 62 can be formed at low cost. This makes it possible to provide a vehicle window glass that can suppress the generation of abnormal noise caused by wind that penetrates into a gap that occurs at the attachment location between the resin-framed glass sheet and the door panel at low cost.

[0062] 6 to 8, the molding 51 may be provided around the periphery of the glass plate 10 by mounting the glass plate 10 in a mold having a cavity corresponding to the shape of the molding 51 and injecting the above-mentioned synthetic resin (molten synthetic resin) into the cavity. Alternatively, a molding 51 made of resin formed separately from the glass plate 10 may be fitted around the outer periphery of the glass plate 10.

[0063] Other configurations of the vehicle window glass 2 shown in Figs. 6 to 8 are similar to those of the vehicle window glass shown in Figs. 1 to 5, so duplicated explanations will be omitted.

[0064] While 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, and combinations that may be made by a person skilled in the art within the scope of the invention as defined in the claims of the present application.
