PROBLEM TO BE SOLVED: To prevent deformation even in the case of an axial rectangular cross-section coiled spring, in a drag knob and a fishing reel.SOLUTION: A drag knob includes: an operation member 67 that is rotatably provided in a reel body 2 a coiled spring 73 that is expanded/contracted in a rotary shaft direction of the operation member 67 by rotation of the operation member 67 a retainer member 66 that imparts a drag force to a spool 4 by receiving an urging force brought about by the coiled spring 73 and a sliding member 63 that is arranged between the coiled spring 73 and the retainer member 66 in the rotary shaft direction and that is lower in friction coefficient than the retainer member 66.COPYRIGHT: (C)2014,JPO&INPIT【課題】ドラグつまみ及び釣り用リールにおいて、軸方向の断面が矩形状のコイルバネであっても変形を防ぐ。【解決手段】リール本体2に回転可能に設けられる操作部材67と、操作部材67の回転によって、操作部材67の回転軸方向に伸縮するコイルバネ73と、コイルバネ73による付勢力を受けてスプール4にドラグ力を付与する受け部材66と、回転軸方向においてコイルバネ73と受け部材66との間に配置され、受け部材66より摩擦係数が小さい摺動部材63と、を備える。【選択図】図5
