【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The automobile window glass 12 of the embodiment shown in FIG. 1 is applied to a quarter window, and includes a triangular plate-shaped glass portion 13 and a window frame rubber portion 14 surrounding the outer periphery of the glass portion 13. It is configured.

The window frame rubber portion 14 is molded from polyvinyl chloride, polyvinyl chloride / nitrile rubber polyblend, ethylene propylene rubber, polyurethane or the like by injection or transfer, and the material thereof is limited to rubber. It is not a material but any soft material.

The window frame rubber portion 14 includes a main body 14 a that includes a lip portion 14 b that wraps the peripheral edge of the outer peripheral end surface of the glass portion 13 and is in contact with the peripheral edge of the vehicle body window frame 11 (see FIGS. 2 and 3). And a screw-in expandable rivet body 15 formed on the mounting surface side of the vehicle body window frame 11 side.

A plurality of the rivet bodies 15 are formed on the window frame rubber portion 14 (a total of four over the entire circumference of the window frame rubber portion 14 in the embodiment), each of which is projected toward the vehicle body window frame 11 side of the main body 14a. Is formed so as to project from a flat seating surface 14c.

As shown in FIGS. 2 and 3, mounting holes 11 a are formed on the side of the vehicle body window frame 11 to which the window glass 12 is fixed, at positions corresponding to the respective rivet bodies 15.

Each rivet body 15 is formed in a substantially truncated cone shape, and has a screw hole 15a for screwing the screw 16 from the tip surface to the main body 14a side. Further, on the outer peripheral surface of each rivet body 15, there is formed a projection 15b which is formed continuously or intermittently over the entire circumference. The position of the protrusion 15b is such that the distance h from the seat surface 14a is substantially equal to the thickness t of the vehicle body window frame 11 at the periphery of the mounting hole 11a (see FIGS. 1 and 2).

The projection 15b is for temporary fixing when the ribet body 15 is inserted into the mounting hole 11a of the vehicle body window frame 11, and when the screw 16 is screwed into the screwing hole 15a. If the rivet body 15 expands in diameter and cannot be removed from the mounting hole 11a, the protrusion 15b need not be provided.

The molding of the window frame rubber portion 14 of the embodiment will be described. As shown in FIG. 1, it is composed of two split molds M1 and M2 having a PL surface (divided surface) near the tip of the lip portion 14b. The molding die M0 is used. Each split mold M1 and M2 is provided with a predetermined cavity mold surface (omitted from the reference numeral) for molding the outside of the window frame rubber portion 14 and the inside of the vehicle body window frame 11 side.

Then, the glass part 13 is set on the split mold M2 in the mold open state, and the mold material is clamped to inject the molding material into the cavity (not shown), so that the window frame rubber part 14 can be molded. .

After that, if the mold is opened and released, the automobile window glass 12 of the embodiment can be obtained. Even if the projection 15b is formed on the rivet body 15, the window frame rubber portion 14 is made of a soft material and can be easily released from the mold by strongly pulling it out.

Next, the operation of fixing the window glass 12 of the embodiment to the vehicle body window frame 11 will be described. First, as shown in FIG. 2, each rivet body 15 is inserted into the corresponding mounting hole 11a. Then, the projection 15b is locked to the peripheral edge of the mounting hole 11a, and the window glass 12 is arranged on the vehicle body window frame 11. At this time, a sealant 17 such as butyl rubber is applied to the vehicle body window frame 11 side in advance.

Then, as shown in FIG. 3, the screws 16 are screwed into the screw holes 15 a of the respective rivet bodies 15 to expand the diameter of the respective rivet bodies 15, so that the window glass 12 is fixed to the vehicle body window frame 11. Can be fixed.

As described above, in the window glass 12 of the embodiment, the fixing means for fixing the window frame 11 to the vehicle body window frame 11 is the screw-in expandable rivet body 15 integrally formed with the window frame rubber portion 14, which is the same as the conventional one. In addition, it is not necessary to separately set the bolt 5 when molding the window frame rubber portion 4, and the molding die M0 of the window frame rubber portion 14 has a structure such as a recess for setting the bolt 5 and the surrounding of the bolt 5. Since it is not necessary to adopt the seal structure, the structure of the molding die M0 can be simplified.

Further, in the molding work, it is not necessary to set the bolt 5 as in the conventional case, and the work for removing the burrs attached to the bolt 5 can be omitted, so that the molding work is troublesome. Therefore, the window glass 12 can be easily manufactured.

Further, the fixing means for fixing to the vehicle body window frame 11 is the screw-in expandable rivet body 15, and the removing work after fixing is simply the reverse of the fixing work, by removing the screw 16 from the rivet body 15 and Since it can be performed only by removing the glass 12 from the vehicle body window frame 11, the maintenance and the like are not hindered, and the same effects as those described in the above-mentioned action and effect section of the invention are achieved.
