Abstract
Disclosed is a fishline guide for a fishing rod wherein an intermediate-layer ring made of a thermoplastic synthetic resin incorporating reinforcing fibers is formed integrally between an inner ring made of a hard, abrasion-resistant material, such as metal or ceramics, and a metallic outer ring. Inclined supporting parts and installing parts are continuously formed integrally on the lower side of the intermediate-layer ring on both sides in such a manner that the inclined supporting parts and installing parts partially encompass the outer ring in a secure manner. Also disclosed is a method of producing a fishline for a fishing rod wherein an inner ring of a hard, abrasion-resistant material such as metal or ceramics and a metallic outer ring are concentrically disposed inside molding tools constituted by a pair of opposing upper and lower dies allowing the inner ring and outer ring to be disposed concentrically thereon and having a groove for forming an inclined supporting part and a groove for forming an installing part communicating therewith, and opposing upper and lower slide dies which are respectively fitted into each groove. After a thermoplastic synthetic resin in which reinforcing fibers are mixed is injection-molded from the joint region of the upper and lower slide dies into the space formed inside the molding tools, the forming tools are split so as to form an integral fishline guide.
