A dual-bearing reel includes a reel body, a spool and a waterproof member. The reel body includes a first side plate and a second side plate. The spool includes a bobbin trunk and a first flange. The bobbin trunk is rotatably disposed between the first side plate and the second side plate. The first flange is provided on a first side plate-side end of the bobbin trunk and has a larger diameter than the bobbin trunk. The waterproof member has an annular shape and is disposed in a first side plate-side position in the reel body. Additionally, the first flange includes a rib having an annular shape. The rib extends axially outward from the first flange and has a smaller diameter than an outermost diameter part of the first flange. The waterproof member is disposed in adjacent opposition to an inner peripheral surface of the rib of the first flange.本發明之課題係在於提供可藉由簡單的結構抑制水侵入到軸承構件的內部之雙軸承捲線器。 用以解決課題之手段為，本發明之雙軸承捲線器，係具備：捲線器本體(1)、捲筒(2)及防水構件(5)。捲線器本體(1)係具有第1側板(6a)；及與第1側板(6a)在軸方向上隔著間隔配置之第2側板(6b)。捲筒(2)具有：捲線主體部(12)、第1凸緣部(13)、及第2凸緣部(14)。防水構件係配置於捲線器本體的第1側板側。第1凸緣部(13)係具有環狀肋(13b)，其從第1凸緣部(13)朝軸方向外側延伸，並且較第1凸緣部(13)的最外徑部更小徑。防水構件(5)係與第1凸緣部(13)之肋(13b)的內周面相對向且接近地配置。
