ープルが出て外観を悪くする問題があつた。(Prior Art) For example, a door trim attached to the passenger compartment side of an automobile door has a resin-molded base material coated with a skin material to improve decorative properties. The edges of the outer skin covering the base material are bent toward the back surface of the base material, and the edges are treated by gluing, welding, or stapling. However, bonding requires time for the adhesive to dry, and there is a problem that the adhesive may seep outside, and welding means requires a special jig for edges with complex shapes, making it difficult to perform. With this method, there were problems in that the base material would crack, and if the base material was thin, staples would appear on the surface, worsening the appearance.
