A frame body) has been adopted, but the number of assembling steps is large, and a window glass having excellent watertightness cannot be obtained.

Therefore, in recent years, a vehicle with a frame body, which is generally called a module assembly window (hereinafter referred to as MAW), is integrally formed with a frame body around the plate body and the plate body is mounted on the vehicle together with the frame body. Windows have become popular.

[0004] In this MAW, for example, after a plate-shaped body is provided in a mold and the mold is clamped, resin is injected into the cavity of the mold to integrally form a frame body in the peripheral portion of the plate-shaped body. When mounting the plate-shaped body on the mold, the mounting member for mounting to the vehicle body is mounted on the mold together with the plate-shaped body so that the mounting member for mounting is mounted on the resin frame body. It was possible to attach it to.

The mounting member for mounting may be directly mounted on the plate-shaped body itself. In this case, the mounting member may be mounted on the plate-shaped body with an adhesive, or the plate-shaped body may be provided with a mounting hole. Methods such as mounting members have been adopted.

[0006]

However, the method of directly attaching the attachment member to the plate-like member with an adhesive or the like has a weak attachment strength, requires much time and cost, and is extremely inefficient in working efficiency. It was
In particular, since the adhesive agent is easily deteriorated by ultraviolet rays, it is necessary to coat the plate-shaped body with black ceramic paint in order to cover the adhesive portion. However, it has a drawback that the effective opening area of the paint is substantially reduced.

Further, when integrally mounting the resin frame body on the peripheral portion of the plate-shaped body, when the mounting member is mounted on the die together with the plate-shaped body and the mounting member is mounted on the frame body, the resin with the mounting member is attached. A special mold for manufacturing the frame-integrated window must be prepared, and there is a drawback that two or more kinds of molds are required depending on the case. Furthermore, in such a case, the shape and size of the mounting member, the degree of freedom of the place where the mounting member is mounted, etc. depend on the type of mold, and it is difficult to flexibly respond to design changes of the mounting member. there were.

The present invention is intended to solve the above-described drawbacks of the prior art, and to provide a novel method of manufacturing a vehicle window with a mounting member, which has not been known in the past. It is a thing.
