A dual-bearing reel is attachable to a fishing rod and releases a fishing line forward. The dual-bearing reel includes a reel unit, a spool for winding the fishing line, a handle and a level wind mechanism. The spool is rotatably disposed in the reel unit. The handle is rotatably disposed on a lateral part of the reel unit. The level wind mechanism uniformly winds the fishing line onto the spool. The level wind mechanism includes a worm shaft, a guide member and a slide member. The worm shaft includes a helical groove. The guide member is disposed on an outer peripheral side of the worm shaft, and includes an opening and at least one water drain. The opening extends in a lengthwise direction of the worm shaft. The slide member slides along the guide member while engaged with the helical groove.防止水從均勻捲線機構朝捲線器本體內部滲入。雙軸承捲線器(100),是具備:捲線器本體(1)、及捲線用的捲筒(2)、及操作桿(3)、及均勻捲線機構(5)。捲線用的捲筒(2),是可旋轉地被設於捲線器本體(1)。操作桿(3),是可旋轉地被設於捲線器本體(1)的側部。均勻捲線機構(5),是具有:設有螺旋狀溝(17a)的蝸桿軸(17)、及導引構件(18)、及導引軸(19)、及滑動構件(20)。導引構件(18),是被配置於蝸桿軸(17)的外周側且具有:朝蝸桿軸(17)的長度方向延伸的開口部(18a)、及至少1個排水孔(18b)。滑動構件(20),是卡合於螺旋狀溝(17a),沿著導引構件(18)及導引軸(19)滑動。2‧‧‧捲筒6‧‧‧框架6a‧‧‧第1側板6b‧‧‧第2側板6c‧‧‧連結部6d‧‧‧裝設部6e‧‧‧開口9‧‧‧捲筒軸15‧‧‧第2齒輪17‧‧‧蝸桿軸17a‧‧‧螺旋狀溝18‧‧‧導引構件18a‧‧‧開口部18b‧‧‧排水孔19‧‧‧導引軸20‧‧‧滑動構件21‧‧‧第1貫通孔22‧‧‧第2貫通孔23‧‧‧卡合構件
