[Problem] To provide a dual-bearing reel capable of reliably functioning a mounting and dismounting mechanism in a restricted position. [Technical content] The dual-bearing reel (1) is provided with a reel body (3) and a mounting and dismounting mechanism (11). The attaching and detaching mechanism (11) includes a first side cover (15), a supporting member (31), and a locking member (33). The support member (31) is provided on the first side plate (21). The lock member (33) is configured to be swingable with respect to the support member (31). The attaching and detaching mechanism (11) uses the supporting member (31) and the locking member (33) to permit or restrict the rotation of the first side cover (15) with respect to the first side plate (21). Here, when the first side cover (15) is rotated and operated when the lock member (33) is arranged at the restricted position, the engaging portion (40) restricts the locking from the restricted position to the permitted position The swinging manner of the member (33) will be pushed by the engaging portion (35).[課題]提供一種可以將裝卸機構在限制位置中確實地功能的雙軸承捲線器。[技術內容]雙軸承捲線器(1)，是具備：捲線器本體(3)、及裝卸機構(11)。裝卸機構(11)，是具有：第1側蓋(15)、及支撐構件(31)、及鎖定構件(33)。支撐構件(31)，是被設於第1側板(21)。鎖定構件(33)，是對於支撐構件(31)可擺動地構成。裝卸機構(11)，是使用支撐構件(31)及鎖定構件(33)，許可或是限制第1側蓋(15)對於第1側板(21)的轉動。在此，在鎖定構件(33)被配置於限制位置的狀態中，第1側蓋(15)被轉動操作的情況時，卡合部(40)，是以限制從限制位置朝許可位置的鎖定構件(33)的擺動的方式，將被卡合部(35)推壓。
