PROBLEM TO BE SOLVED: To provide a fishing rod capable of raising resistive force to bending and improving fish up force, by mounting a simple structure on a part on the butt side of a rod body on the smaller-diameter side.SOLUTION: An outer peripheral surface 2A on the butt side of a second rod 2 is brought into pressure contact with an inner peripheral surface 3A on the tip side of a third rod 3, to set the second rod 2 and the third rod 3 in an elongated state. A core material 5 is mounted on an inner space of the end on the butt side of the second rod 2, and the core material 5 is formed into such a shape that the part on the butt side thereof can be held on the inner peripheral surface of the end on the butt side of the second rod 2, and the tip part of the core material 5 is formed into a tapered shape.COPYRIGHT: (C)2009,JPO&INPIT【課題】 小径側竿体の元側部分に簡単な構造物を装着することによって、前記した曲げに対する対抗力を高め、釣上げ力の向上を図ることのできる釣り竿を提供する。【解決手段】 二番竿2の元側外周面2Aを三番竿3の先側内周面3Aに圧接して、二番竿2と三番竿3とを伸長状態に設定する。二番竿2の元側端部の内部空間に芯材5を装着し、芯材5を、その元側部分が二番竿2の元側端部の内周面に保持可能な形状に形成するとともに芯材5の先側部分が先細り状態となる形状に形成してある。【選択図】 図2
