A drag mechanism is configured to brake rotation of a spool in a fishing-line releasing direction about a handle shaft. The drag mechanism includes a drag regulation member, a drag washer, a handle, a one-way clutch, and a cam. The drag regulation member is configured to regulate drag force, where the drag regulation member includes an operating part and a regulation nut. The regulation nut is axially movably and unitarily rotatably coupled to the operating part. The regulation nut is screwed onto an outer peripheral surface of a tip end of the handle shaft. The drag washer is disposed onto the handle shaft. The handle is disposed between the drag washer and the drag regulation member. The one-way clutch is configured to prevent rotation of the handle shaft in the fishing-line releasing direction. The cam mechanism is configured to increase the drag force.一種牽引機構,可由操作桿及牽引力調整構件調整牽引力,在牽引操作時使牽引力調整構件及操作桿不會朝手把軸方向大移動。牽引機構(29),是具備:牽引力調整構件(3)、及牽引墊圈(37)、及操作桿(2)、及第1單向離合器(34)、及凸輪機構(38)。牽引力調整構件(3),是具有操作部(40)及調整螺帽(41)。操作桿(2),是被配置於牽引墊圈(37)及牽引力調整構件(3)之間,在第1位置及位於第1位置的線捲取方向的第2位置之間可預定角度擺動且可一體旋轉地設在手把軸(30)。第1單向離合器(34),是禁止手把軸(30)的線吐出方向的旋轉。凸輪機構(38),是藉由從操作桿(2)的第1位置朝第2位置的擺動,使藉由牽引力調整構件(3)被調整的牽引力增加預定量。A‧‧‧中心軸2a‧‧‧操作桿臂2c‧‧‧安裝孔3‧‧‧牽引力調整構件7b‧‧‧第2側板8b‧‧‧第2側蓋8c‧‧‧第1轂部29‧‧‧牽引機構30‧‧‧手把軸30a‧‧‧第1切面部30b‧‧‧第2切面部30c‧‧‧公螺紋部30d‧‧‧第3切面部30e‧‧‧母螺紋部30f‧‧‧段差31‧‧‧驅動齒輪33‧‧‧軸承34‧‧‧第1單向離合器35‧‧‧棘輪滾輪36‧‧‧第2單向離合器36a‧‧‧外輪36b‧‧‧內輪36c‧‧‧滾子36d‧‧‧卡合突起37‧‧‧牽引墊圈37a‧‧‧內周面37b‧‧‧卡合凹部38‧‧‧凸輪機構39‧‧‧第1推迫構件40‧‧‧操作部40c‧‧‧螺帽收納部40d‧‧‧銷收納部40e‧‧‧環狀突起41‧‧‧調整螺帽42‧‧‧旋轉支撐構件42a‧‧‧內周面42b‧‧‧鍔部42f‧‧‧先端面43‧‧‧碟形彈簧44‧‧‧定位構件44a‧‧‧內周面44b‧‧‧卡合凹部45a‧‧‧第1墊圈構件45b‧‧‧第2墊圈構件46‧‧‧螺栓構件46a‧‧‧頭部47a‧‧‧第1牽引碟片47b‧‧‧第2牽引碟片60‧‧‧牽引操作發聲機構61‧‧‧打擊銷62‧‧‧捲簧63‧‧‧出聲構件63a‧‧‧出聲凹部63b‧‧‧卡合突起64‧‧‧第1蓋構件64a‧‧‧定位突起65‧‧‧螺栓構件66‧‧‧第2蓋構件68‧‧‧螺栓構件72‧‧‧第1凸輪構件74‧‧‧第2凸輪構件74d‧‧‧收納部76‧‧‧第2推迫構件78‧‧‧推迫銷79‧‧‧捲簧
