があるため、さらに、手数が懸かる等の問題があった。Conventional Technology In order to give a steering wheel pad a luxurious feel, it is preferable to cover the surface with a skin made of real leather or synthetic leather. As a result, it was a manual process, which was time-consuming and had the disadvantage that it was difficult to imprint the fine patterns formed on the surface of the molded product into the skin. Furthermore, in order to treat the ends of the skin, it is necessary to fold the skin to the back side of the molded product and adhere it, resulting in further problems such as a time-consuming process.

きるようにするものである。Purpose of the Invention The present invention makes it possible to attach the skin by insert molding and bring it into close contact not only to the surface of the molded product but also to the outer periphery of the back surface at the same time as molding, thereby making it extremely easy to make the skin fit tightly, and also simplifying the terminal treatment. This makes it possible to create detailed patterns on the epidermis.

部分４ａを裁断除去する。In the first embodiment shown in FIG. 3, a core insert 3 is attached to a movable mold 5, and a skin 4 is further attached to the front side of the core insert 3. The skin 4 is set to be radially larger than the surface that forms the pad surface of the cavity formed by clamping the movable mold 5 and the fixed mold 6, and the movable mold Insert insert 7 into the four parts of 5,
The insert 7 presses the skin 4 along the outer periphery of the core insert 3. Thereafter, the movable mold 5 and the fixed mold 6 are clamped, and vinyl chloride resin 11 is injected into the cavity 8 through the gate 12. The gate in this case uses a submarine date. The resin 11 is filled between the core insert 3 and the skin 4, and the skin 4 is filled with the injection pressure of the resin 11.
is suppressed to fixed type 6. Therefore, the concavo-convex pattern (not shown) formed on the fixed mold 6 is formed on the skin 4, and the pad main body 9, which is made of a resin molded product, is closely attached from the surface and side surfaces to the outer peripheral portion of the back side. After the injection molding, it is taken out from the mold, the insert 7 is removed, and the unnecessary end portion 4a of the skin 4 is cut and removed.
