The spool brake device is equipped with a brake unit, a detector, and a controller. The controller controls the braking force by the brake unit based on the rotational speed of the spool detected by the detector. When the rotational speed is less than the predetermined rotational speed, the controller controls the braking force by the brake unit in the regular braking mode. In the regular braking mode, the controller changes the braking force by the brake unit according to the rotational speed. On the other hand, when the rotational speed is equal to or higher than the predetermined rotational speed, the controller controls the braking force by the brake unit in the emergency braking mode, during the period of predetermined time. In the emergency braking mode, the controller makes the braking force by the brake unit larger than the braking force in the regular braking mode.本發明的課題在於防止拋投時之漁線纏結並防止斷線。捲軸制動裝置4具備制動部41、檢測部42、及控制部43。控制部43基於檢測部42所檢測之捲軸之旋轉速度，控制制動部41之制動力。控制部43於旋轉速度未達特定之旋轉速度時，以通常制動力模式控制制動部41之制動力。控制部43於通常制動力模式中，根據旋轉速度改變制動部41之制動力。另一方面，控制部43於旋轉速度為特定之旋轉速度以上時，在特定時間內以緊急制動力模式控制制動部41之制動力。控制部43於緊急制動力模式中，使制動部41之制動力大於通常制動力模式下之制動力。
