PROBLEM TO BE SOLVED: To solve problems in a splicing part of a tip part with a buried part in a conventional fishing rod in which a stress concentrates on one point during a fishing operation and a casting operation to cause buckling and breakage, and a sufficient bonding strength cannot be obtained due to a small bonding surface area in the splicing part, and further, the bend of the fishing rod becomes unnatural due to the reinforcing material of the splicing part having a configuration of a cylinder.SOLUTION: In a splicing part of a fishing rod, an insertion part formed as a conical shape and a shaft passing the center of the insertion part of the conical shape are spliced with a tip part having a receptacle with the inside of a hollow structure excavated in the conical shape or a buried part, and a bonding surface area of the splicing part is widened, and thereby stress dispersion and strength are improved. Accordingly, an overall length of the splicing part can be shortened, and thereby the bend of a natural fishing rod can be achieved.COPYRIGHT: (C)2016,JPO&INPIT【課題】従来の釣竿におけるティップ部とベリー部の接合部は、魚釣りの動作や、キャスティング動作時に、応力が一点に集中し、折れや破損の原因となっていた。また、接合部において、接着表面積が小さいため、十分な接着強度が得られず、さらに、接合部の補強材が円筒状をしていたため、釣竿の曲がりが不自然なものになるという問題があった。【解決手段】釣竿の接合部において、円錐状に成型された挿入部と、前記円錐状の挿入部の中心を通る軸と、中空構造の内部が円錐状に掘削された受け口を有するティップ部、もしくは、ベリー部を接合し、接合部の接着表面積を広げ、応力分散と、強度を向上することで、接合部の全長を短くすることが可能となり、自然な釣竿の曲がりを実現する。【選択図】図1
