A fishing reel capable of casting a fishing line in a forward direction includes a reel body, a rotor, a one-way clutch and a case member. The rotor is rotatable relative to the reel body about an axis of rotation and has an internal space. The one-way clutch is configured to transmit power in only one direction. The case member is disposed in the internal space of the rotor and houses the one-way clutch, and has a flange portion projecting in a radially outward direction and a fixing portion disposed behind the flange portion in a position overlapping a part of the flange portion, as viewed from an axial direction, and being fixed to the reel body.本發明之釣具用捲線器之課題在於使收容單向離合器之殼體構件之徑向之尺寸小型化，並利用殼體構件抑制水分向單向離合器浸入。紡車式捲線器100具有捲線器本體2、轉子4、單向離合器10、及殼體構件20。轉子4能以旋轉軸心O為中心而相對於捲線器本體2旋轉，且具有內部空間4d。單向離合器10僅單向傳遞動力。殼體構件20設於轉子4之內部空間4d內，可收容單向離合器10。殼體構件20具有向徑向外側突出之凸緣部24、及設於較凸緣部24更靠後方且當自軸向觀察時與凸緣部24之一部分重疊的位置並被固定於捲線器本體2之固定部25。
