PROBLEM TO BE SOLVED: To prevent fluid from flowing into the inside of a drag knob even if water pressure acts on a sealing member.SOLUTION: The drag knob 61 includes a knob part 63, a first sealing member 64 and a second sealing member 65. The knob part has a first member 66, a second member 67 installed so as to be freely turnable relative to the first member, screwing in a spool shaft, and having a protrusion part 75b cylindrically protruded to the first member so as to cover a flange part, and a connecting member 74 for connecting the first member and the second member so as to be unmovable in the axial direction and freely rotatable, and regulates the drag power. The first sealing member is arranged between the spool and the first member, and seals the clearance between the spool and the first member. The second sealing member is arranged between the first sealing member and the second member, has a cylindrical contact part 64a capable of contacting with the outer periphery of the protrusion part of the second member, and seals the clearance of the first member and the second member.COPYRIGHT: (C)2009,JPO&INPIT【課題】シール部材に水圧が作用しても、ドラグつまみの内部への液体の流入を防止できるようにする。【解決手段】ドラグつまみ61は、つまみ部63と、第1シール部材64と、第2シール部材65と、を備えている。つまみ部は、第1部材66、第1部材と相対回動自在に設けられスプール軸に螺合するとともに、鍔部を覆うように第1部材に向けて筒状に突出する突出部75bを有する第2部材67、及び第1部材と第2部材とを軸方向移動不能かつ回転自在に連結する連結部材74を有し、ドラグ力を調整するためのものである。第1シール部材は、スプールと第1部材との間に配置され、スプールと第1部材との隙間をシールする部。第2シール部材は、第1シール部材と第2部材との間に配置され、第2部材の突出部の外周面に接触可能な筒状の接触部64aを有し、第1部材と第2部材との隙間をシールする。【選択図】図9
