A spool of a spinning reel includes a support member, a spool body, a drag mechanism, a first sealing member, and a second sealing member. The support member is detachably connected to a spool shaft. The spool body includes a housing recess that is frontally open and rotatably attached to the support member. The drag mechanism decelerates the spool body and includes a front friction portion that has a press washer with an inner peripheral surface opposed to an outer peripheral surface of a front portion of the support member. The press washer contacts a drag regulation member. The housing recess accommodates the friction portion. The first sealing member seals a gap created between the inner peripheral surface of the press washer and the outer peripheral surface of the support member. The second sealing member seals the gap created between the outer peripheral surface of the press washer and the housing recess.無關於捲筒的裝卸,可以防止液體滲入牽引墊圈。紡車式捲線器的捲筒4,是具備:支撐構件25、及捲筒本體7、及牽引機構8、及第1密封構件59、及第2密封構件60。支撐構件,是可裝設於捲筒軸。捲筒本體,是具有朝前方圓形開口的第1收納凹部,可旋轉自如地裝設於支撐構件。牽引機構,是具有與支撐構件的前部外周面相面對配置的內周面且包含與牽引調整構件接觸的按壓墊圈,具有被收納於第1收納凹部的前摩擦部,制動捲筒本體。第1密封構件,是密封按壓墊圈內周面及支撐構件的外周面的間隙。第2密封構件,是密封按壓墊圈的外周面及第1收納凹部的間隙。
