A dual-bearing reel (1) includes a reel body (2) that supports a spool so as to be rotatable, and a spool braking mechanism (20). The spool braking mechanism (20) includes an operator (21) and a braking force adjuster (22). The operator (21) is configured to be rotatable and axially immovable with respect to the reel body (2), and has an internal space (S) extending in an axial direction and opening axially outwardly. The braking force adjuster (22) is disposed in the internal space (S) and is configured to be axially movable with respect to the reel body (2) in conjunction with rotation of the operator (21) to adjust a braking force of the spool (4).[課題] 提供一種釣魚用捲線器，其具有能夠使操作構件的軸方向長度短且能夠輕易掌握捲筒的制動力的大小之捲筒制動機構。[解決手段] 雙軸承捲線器(1)，係具備捲線器本體(2)、捲筒制動機構(20)。捲筒制動機構(20)，係具有操作構件(21)、制動力調整構件(22)。操作構件(21)，係構成為對於捲線器本體(2)能夠旋轉且無法於軸方向移動。操作構件(21)，係具有於軸方向延伸且於軸方向外側開口的內部空間(S)。制動力調整構件(22)，係配置於操作構件(21)的內部空間(S)。制動力調整構件(22)，係為了調節捲筒(4)的制動力，構成為能夠連動於操作構件(21)的旋轉而對於捲線器本體(2)於軸方向移動。
