The drag mechanism includes a friction disk, a cover member, a brake disk, and a drag adjusting mechanism. The friction disk is in a storage space of a first flange portion of a spool and has an engaging recess formed in an external circumferential surface. The cover member has a cylindrical portion that fits into an internal circumferential surface of the storage space,an engaging protrusion on a distal end surface of the cylindrical portion to engage with the engaging recess, and a protruding portion that mate closely with an end face of the first flange portion. The cover member is fixed to the first flange portion and covers the storage space from the outside. The brake disk is arranged in the storage space facing opposite the friction disk and constructed not to rotate in a line reel-out direction. The cam mechanism is designed to move the friction disk and the spool together along an axial direction of the spool with respect to the brake disk such that the friction disk is pressed against the brake disk.對於牽引機構,即使形成容易將收納空間密封的形狀也可以將摩擦碟片止轉。牽引機構(6),是具備:兩摩擦碟片(21)、及蓋構件(26)、及制動碟片(22)、及牽引調整機構。摩擦碟片,是配置於捲筒(4)的第1凸緣部(9b)的收納空間,在外周面具有卡合凹部(21a)。蓋構件(26),是具有:嵌合在收納空間的內周面的圓筒部(26a),設在圓筒部的前端面並卡合於卡合凹部的卡合突起(26e)及可密合地設在第1凸緣部的端面的突出部,且被固定於第1凸緣部將收納空間從外方覆蓋。制動碟片,是在收納空間與摩擦碟片相面對配置,朝線吐出方向不可旋轉。凸輪機構,是將摩擦碟片與捲筒一起對於制動碟片朝捲筒軸方向相對移動並將摩擦碟片及制動碟片壓接。6...牽引機構21...摩擦碟片21a...卡合凹部21b...外側面22...制動碟片23...環狀溝24...裝設部24b...連結溝24c...止轉部24d...限制面24e...裝設溝25...碟片部25a...卡合孔26...蓋構件26a...圓筒部26b...底部26c...通過孔26d...外周面26e...卡合突起26f...突出部26g...螺絲通過孔26h...前端27...止脫構件29...密封構件29a...唇緣57...轉動軸61...小齒輪61a...齒61b...支撐部61c...貫通孔64...單向離合器66...棘輪滾輪66a...棘輪齒66b...卡合突起67...掣子67a...支撐孔67b...轉動支撐部67c...爪部67d...狹縫68...彈簧構件68a...裝設部68b...臂部69...支撐板69a...裝設溝69b...連結孔
