A dual-bearing reel spool braking device is configured to brake a spool that is rotatably mounted on a reel body by centrifugal force. The dual-bearing reel spool includes at least one brake shoe, a rotating member and a brake drum. The brake shoe is arranged to apply a braking force to the spool. The rotating member is configured to rotate in conjunction with the spool. The rotating member includes a pivot shaft portion and a fixing portion. The pivot shaft portion pivotally supports the brake shoe and that movably supports the brake shoe in an axial direction of the pivot shaft portion. The fixing portion engages the brake shoe and non-pivotally fixes the brake shoe. The brake drum is arranged to selectively contact the brake shoe.本發明係於制動蹄片擺動之捲筒制動裝置中，可容易地更換制動蹄片。本發明之雙軸承捲線器10之捲筒制動裝置25，係藉由離心力而將旋轉自如地安裝於捲線器本體11之捲筒14制動。該捲筒制動裝置25包含用於制動捲筒14之至少1個制動蹄片64、旋轉構件62、及制動鼓66。旋轉構件62係與捲筒14之旋轉連動地旋轉。旋轉構件62具有擺動軸部63c、及固定部63d。擺動軸部63c係將制動蹄片64可擺動且可於擺動軸方向上移動地支持。固定部63d係卡合於制動蹄片64，且將制動蹄片64無法擺動地固定。制動鼓66之錐面66a可與擺動之制動蹄片64接觸。
