A present dual-bearing reel spool braking device is configured to apply a braking force to a spool that is rotatably mounted on a reel body with a centrifugal force. The spool braking device includes a rotating member, a brake shoe, a brake drum, and a selective fixing member. The rotating member rotates in conjunction with the rotation of the spool. The brake shoe is supported by a rotating member so as to be pivotal between a braking position where the brakes are applied to the spool with a centrifugal force and a non-braking position where a non-braking rotation of the spool is allowed. The brake drum is configured to come into contact with the brake shoe. The selective fixing member is mounted to the rotating member. The selective fixing member selectively fixes the brake shoe to the non-braking position by selectively engaging with the brake shoe.本發明之目的在於可容易地設定制動靴之能作動狀態與無法作動狀態。本雙軸承捲線器10之捲筒制動裝置25，藉由離心力而制動旋轉自如地安裝於捲線器本體11之捲筒14。本捲筒制動裝置25具備旋轉構件62、制動靴64、制動鼓66、及選擇固定構件67。旋轉構件62與捲筒14之旋轉連動地旋轉。制動靴64可於藉由離心力而制動捲筒14之制動位置、與以非制動而允許捲筒14之旋轉之非制動位置之間移動地受支持於旋轉構件62。制動鼓66可接觸於制動靴64。選擇固定構件67安裝於旋轉構件62。選擇固定構件67藉由選擇性地卡合於制動靴64，而將制動靴64選擇性地固定於非制動位置。
