The fishing tackle winder of the present invention makes the simple structure of the opening portion by Magnetic sealing mechanisms sealing in the case where not increasing number of parts, to make handling ease.The fishing tackle winder of the present invention has winder ontology 1, the pinion gear 3 for being rotatably supported what winder ontology 1 and magnetic substance 7, keeps pinion gear 3 prominent from opening portion and locally accommodates pinion gear 3 and the opening portion of The lid component 6 and what The lid component 6 that is fixed with respect to what winder ontology 1 is by the Magnetic sealing mechanisms of sealing between The lid component 6 and pinion gear 3. Magnetic sealing mechanisms include magnet 8, clip magnet 8 and configure what magnet 86 side of The lid component magnetic sheet 9a and configuration what magnet 8 with the magnetic sheet 9b of 6 opposite side of The lid component and keep magnetic fluid 10 in the gap of what magnetic substance 7 and magnetic sheet 9a and magnetic sheet 9b. Moreover, the big what magnet of outer diameter that the magnet comprising magnetic sheet 9a, magnet 8 and magnetic sheet 9b constitutes the face for the private side of body to connect with the end face around the opening portion of The lid component 6 constitutes the outer diameter in the face of the outer side of body.本發明之釣具捲線器在不增加零件數量下使得由磁性密封機構密封之開口部之構造簡單化，從而使加工容易。本發明之釣具捲線器具備捲線器本體1、可旋轉地支持於捲線器本體1之小齒輪3及磁性體7、使小齒輪3自開口部突出而局部地收容小齒輪3並相對於捲線器本體1而被固定之蓋構件6、及於蓋構件6之開口部將蓋構件6與小齒輪3之間密封之磁性密封機構。磁性密封機構包含磁鐵8、夾持磁鐵8並配置於磁鐵8之蓋構件6側之磁性板9a及配置於磁鐵8之與蓋構件6相反側之磁性板9b、以及保持於磁性體7與磁性板9a及磁性板9b之間隙內之磁性流體10。而且，包含磁性板9a、磁鐵8及磁性板9b之磁鐵構成體之與蓋構件6之開口部周圍的端面相接之內部側之面之外徑大於磁鐵構成體之外部側之面之外徑。
