In the spinning fishing Lille, the structure of the opening sealed by the magnetic seal mechanism is simplified without increasing the number of parts, and the processing is facilitated.Solution: the Lille body 1, the pinion gear 3 rotatably supported on the Lille main body 1 and the magnetic body 7, and a cover member 6 partially receiving the pinion gear 3 projecting from the opening portion of the pinion gear 3, fixed to the Lille body 1, and an opening portion of the lid member 6 with the lid member 6 A magnetic seal mechanism for sealing between pinion gears 3 is provided.The magnetic seal mechanism includes a magnet 8, a magnetic plate 9A sandwiching the magnet 8 and disposed on the lid member 6 side of the magnet 8, a magnetic plate 9b disposed opposite to the cover member 6 of the magnet 8, and a magnetic fluid 10 held in the gap between the magnetic plate 9a and the magnetic plate 9a and the magnetic plate 9b.The outer diameter of the inner surface of the magnet member formed of 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 lid member 6, is larger than the outer diameter of the outer surface of the magnet structure.Diagram【課題】魚釣用スピニングリールにおいて、部品数を増加させることなく、磁気シール機構でシールされる開口部の構造を単純にし、加工を容易にする。【解決手段】リール本体１と、リール本体１に回転可能に支持されるピニオンギア３および磁性体７と、開口部からピニオンギア３を突出させてピニオンギア３を部分的に収容し、リール本体１に対して固定される蓋部材６と、蓋部材６の開口部で蓋部材６とピニオンギア３の間をシールする磁気シール機構と、を備える。磁気シール機構は、磁石８、磁石８を挟持し磁石８の蓋部材６側に配置される磁性板９ａおよび磁石８の蓋部材６とは反対側に配置される磁性板９ｂ、ならびに、磁性体７と磁性板９ａおよび磁性板９ｂとの隙間に保持される磁性流体１０、を含む。そして、磁性板９ａ、磁石８および磁性板９ｂからなる磁石構成体の、蓋部材６の開口部周囲の端面に接する内部側の面の外径は、磁石構成体の外部側の面の外径より大きい。【選択図】図２
