A dual-bearing reel capable of reeling in and reeling out a fishing line includes a reel body, a spool, a spool shaft, an operating member, and an oscillating mechanism. The spool is rotatably supported by the reel body. The spool shaft supports the spool. The operating member is movably provided on the reel body and moves to perform an adjustment operation on a braking force that acts on the spool. The oscillating mechanism causes the fishing line to oscillate in the axial direction in synchronization with a rotation of the spool.本發明之課題係在於當不斷送出釣線時,容易獲得穩定的落下速度。 用以解決課題之手段為,雙軸承捲線器(100)係可進行釣線之捲取及不斷送出,具備有捲線器本體(2)、捲筒(3)、捲筒軸(10)、操作構件(30)及往復移動機構(40)。捲筒(3)係可自由旋轉地裝設在捲線器本體(2)。捲筒軸(10)係支承捲筒(3)。操作構件(30)係可移動地設在捲線器本體(2),藉由移動,調整操作作用於捲筒(3)之制動力。往復移動機構(40)係與捲筒(3)的旋轉同步,使釣線朝軸方向往復移動。
