| 发明名称 | Fishing reel | ||
| 摘要 | Various embodiments provide a fishing reel having a light-weight, compact and easy-to-assemble magnetic seal mechanism which allows greater freedom in material selection of the rotating member. A fishing reel according to one embodiment comprises a rotating body rotatably supported via a ball bearing and a magnetic seal mechanism for sealing the ball bearing. In one aspect, the magnetic seal mechanism comprises a magnet disposed in parallel with either a magnetic inner or outer ring of the ball bearing, and magnetic fluid disposed between the magnet and said inner or outer ring, magnetic fluid being retained by a magnetic circuit formed therebetween to seal space defined between the magnet and said inner or outer ring. | ||

| 主权项 | 1. A fishing reel comprising: a rotating body rotatably supported via a ball bearing and a magnetic seal mechanism for sealing the ball bearing, the magnetic seal mechanism comprising: a circular nonmagnetic supporting body; a magnet disposed in parallel with either a magnetic inner or outer ring of the ball bearing; and magnetic fluid disposed between the magnet and said inner or outer ring, the magnetic fluid being retained by a magnetic circuit formed there between to seal a space defined between the magnet and said inner or outer ring, wherein the magnet is fixed to an outer surface of the nonmagnetic supporting body. | ||
