Sinking defects were likely to occur and it was difficult to ensure the appearance quality. FIG. 6 is a partial cross-sectional view of a window glass in which a molding part and glass are integrated, obtained by conventional injection molding. F is an appearance defect called a sink mark, which is a phenomenon caused by the difference in the amount of resin shrinkage in thick-walled and uneven-walled parts of the product. The present invention solves the above problems, does not cause sink marks, and
To provide a method for manufacturing a window glass with molding in which the window glass and molding are integrated, which can reduce the weight and achieve freedom in design.

A window with a molding, characterized in that a glass portion and a molding portion are formed by injecting a resin into a cavity, and after molding, gas is injected into the molding portion in a molten state to make the molding portion hollow. This is a method of manufacturing glass.

形成されている。Embodiments Examples of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a front view of a product of an automobile quarter window 1 located at the rear of an automobile, which consists of a transparent glass part 2 and a painted molding part 3. Figure 2 shows
FIG. 1 is a cross-sectional view of an injection mold 10 for molding a quarter window 1, which is composed of a fixed mold 4 and a movable mold 5. The fixed mold 4 and the movable mold 5 are closed, and the molten transparent polycarbonate resin is injection molded into the cavity 6. Cavity 6
It is formed from a plate-shaped cavity glass portion 62 and a cavity molding portion 61 located at the periphery of the glass and having a tongue-shaped cross section.
