The fishing tackle reel of the present invention simplifies the structure of the opening sealed by the magnetic sealing mechanism without increasing the number of parts, thereby facilitating processing.The fishing tackle reel of the present invention is provided with a reel main body 1, a pinion 3 and a magnetic body 7 rotatably supported by the reel main body 1, and the pinion 3 protrudes from the opening to partially accommodate the pinion 3 relative to the reel The cover member 6 to which the main body 1 is fixed, and a magnetic sealing mechanism that seals between the cover member 6 and the pinion 3 at the opening of the cover member 6. The magnetic sealing mechanism includes a magnet 8, a magnetic plate 9a arranged on the side of the cover member 6 of the magnet 8 and a magnetic plate 9b arranged on the side of the magnet 8 opposite to the cover member 6, and held by the magnetic body 7 and The magnetic fluid 10 in the gap between the plate 9a and the magnetic plate 9b. Moreover, the outer diameter of the inner surface of the magnet structure including the magnetic plate 9a, the magnet 8 and the magnetic plate 9b, which is in contact with the end surface around the opening of the cover member 6, is larger than the outer diameter of the outer surface of the magnet structure .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。
