PROBLEM TO BE SOLVED: To provide a bottom plug fitting structure of a fishing rod in which it is prevented that a bottom plug is accidentally removed and missed, an outer peripheral surface part of a root rod where the bottom plug is attached is protected, and gripping performance is improved when the root rod is gripped.SOLUTION: An intermediate fitting body 2 is bonded to a root rod 1 by means of capping. A bottom plug 3 is screwed into the inside of a rod bottom end part 1A of the root rod 1 that is inserted into the space of the intermediate fitting body 2. The root rod 1 is attached to the intermediate fitting body 2 in a state in which a rod bottom side end of the bottom plug 3 is positioned on the side closer to a rod tip than to the rod bottom end of the intermediate fitting body 2. An engagement ridge 2B is erected on an outer peripheral surface of the intermediate fitting body 2, and a grip part 4 where an engagement recess 4D for engaging with the engagement ridge 2B is formed is engaged with the intermediate fitting body 2, with the grip part 4 being attached for rotation in a circumferential direction relative to the intermediate fitting body 2.COPYRIGHT: (C)2015,JPO&INPIT【課題】 不測に尻栓が外れて紛失することを防止できるとともに、元竿の尻栓を装着した外周面部の保護と、元竿を握った場合に、グリップ性能を高める釣り竿の尻栓取付構造を提供する。【解決手段】 元竿1に中間取付体2を外嵌する状態で固着する。中間取付体2の内部空間に嵌入された元竿1の竿尻端部1Aの内側に尻栓3を螺着する。元竿1を中間取付体2に対して、尻栓3の竿尻側端が中間取付体2の竿尻端より竿先側に位置する状態に装着する。中間取付体2の外周面に係合用突条体2Bを立設し、その係合用突条体2Bに係合する係合凹部4Dを形成した握り部4を中間取付体2に係合させて、中間取付体2に対して握り部4を周方向に回転自在に装着してある。【選択図】 図2
