A dual-bearing reel spool braking device for applying a braking force to a spool rotatably mounted on a reel body, the dual-bearing reel spool braking device includes a brake drum, a rotating member, and a brake shoe. The brake drum is configured to be non-rotatably attached to the reel body. The rotating member is configured to rotate in conjunction with the rotation of the spool. The brake shoe is detachably attached to the rotating member and configured to contact the brake drum. The rotating member comprises a main body section, a swinging shaft section indisposed on the main body section and swingably supporting the brake shoe, and a main body section configured to guide the brake shoe when mounting the brake shoe to the swinging shaft section.本發明之目的在於提供一種可將制動蹄片恰當地組裝於旋轉構件之捲軸制動裝置。本捲軸制動裝置25包括制動鼓66、旋轉構件62及制動蹄片64。制動鼓66係無法旋轉地安裝於捲線器本體11上。旋轉構件62係與捲軸14之旋轉聯動地旋轉。制動蹄片64係可裝卸地安裝於旋轉構件62。制動蹄片64係利用由旋轉構件62之旋轉產生之離心力進行擺動，且可與制動鼓66接觸。此處，旋轉構件62包括：本體部63a、擺動軸部63c、及安裝導引部63e、63f。擺動軸部63c係支持制動蹄片64使之可擺動。於相對於擺動軸部63c安裝制動蹄片64之情形時，安裝導引部63e、63f引導制動蹄片64。
