A dual-bearing reel includes a cover and a dial disc including an engagement groove having a first radius centered on the central shaft, and capable of adjusting a braking force of the spool is formed. A projection is fixed to a first side plate, and engages the engagement groove when the cover covers the first side plate. A guide groove is formed on the dial disc, which extends in a direction that is different from that of the arc of the engagement groove and is in communication with the engagement groove, and through which the projection is capable of passing and being detached from the dial disc. The projection is configured to be detached from the dial disc through the guide groove when the intersection point between the engagement groove and the guide groove is aligned with the projection and when the cover covers the first side plate.於本發明之雙軸承捲線器中，不需要將旋轉式開閉蓋鎖定之機構之空間。 本發明之雙軸承捲線器具備：蓋16a，其能夠圍繞捲線筒軸20搖動；轉盤式圓盤60，其能夠圍繞自捲線筒軸20隔開之中心軸61旋動地支持於蓋16a且形成有以中心軸61為中心之第1半徑之圓弧狀之卡合槽62，而能夠調節捲線筒之制動力；及突起70，其固定於第1側板15a，且於蓋16a覆蓋第1側板15a之狀態下，卡合於卡合槽62。轉盤式圓盤60上形成有連通於卡合槽62且於與第1半徑之圓弧不同之方向延伸，而可供突起70通過從而自轉盤式圓盤60脫離之引導孔63，於使卡合槽62與引導孔63之交點64與蓋16a覆蓋第1側板15a時之突起70對齊之狀態下，突起70能通過引導孔63而自轉盤式圓盤60脫離。
