Abstract

PURPOSE:To simply mount a hinge, and enhance the design of a product by covering a mounting part of a metal hinge having a rotatable part with resin except for the hinge and welding or bonding the hinge with its mating member. CONSTITUTION:A plurality of windows 2a are opened to a mounting part 2 of a metal-made hinge and coated with resin 3 and integrated into one piece except for a rotatable hinged portion 1. Then, this hinge is welded to or bonded to a plastic-made box and a cover or a door. This hinge eliminates nates the need to mount with a screw and joins with its mating member in a wide area by eliminating the need for threaded mounting, which prevents the generation of cracks due to stress concentration and enhance the design quality of products as well. It is, therefore possible to enhance mounting efficiency.
