PROBLEM TO BE SOLVED: To enable a cost to be reduced by facilitating assembly, and to increase attachment strength.SOLUTION: A knob 30 of a fishing reel comprises a core material 31 that is rotatably supported via a support shaft, and a cylindrical holding member 35 that is formed of an elastically deformable material and that is externally fitted to the core material 31. The core material 31 is provided with a deformation imparting part that abuts on an inner surface 35a of the holding member 35 to swelling-deform an outer shape of the holding member 35 in a direction orthogonal to the axial direction of the support shaft 20.COPYRIGHT: (C)2015,JPO&INPIT【課題】組み立てが簡単でコストを低減することができ、しかも、取付強度を高める。【解決手段】魚釣用リールのツマミ30は、支軸を介して回転自在に支持される芯材31と、弾性変形可能な材料で形成され、芯材31に外嵌される筒状の把持部材35と、を備えた魚釣用リールのツマミ30であって、芯材31には、把持部材35の内面35aに当接して支軸20の軸線方向と直交する方向に把持部材35の外形状を膨出変形させる、変形付与部が設けられている構成とした。【選択図】図2
