ABSTRACT:
A fishing rod includes an outer rod section, and an inner rod section inserted into the outer rod section for telescopic movement. The inner rod section is retainable in an extended position and a compressed position relative to the outer rod section. The inner rod section includes a tapered portion extending from an intermediate position to a tip end thereof and tapering toward the tip end, and a straight portion extending from the intermediate position to a rear end. Further, the inner rod section defines an inside wall becoming progressively thicker from the intermediate position to the rear end. The inner rod section is manufactured by using a mandrel having a tapered outer surface tapering from an intermediate position to a forward end, and a straight outer surface from the intermediate position to a rear end thereof. A polypropylene sheet is wound on the mandrel to form an intermediate swell, and then a prepreg is wound on the polypropylene sheet such that an outer surface thereof rearwardly of the intermediate swell extends parallel to the straight outer surface of the mandrel. The resulting product is baked, and thereafter the mandrel and the polypropylene sheet are removed to complete the inner rod section which is fitted in the outer rod section.
