Abstract
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.

A fishing spinning reel, comprising:
- a rotor rotated by rotational operation of a handle to wind a fishing line around a spool;
- a line roller provided on the rotor and configured to guide the fishing line to the spool;
- and
- a magnetic seal mechanism for sealing a bearing supporting the line roller rotatably,
- wherein the magnetic seal mechanism includes a magnet disposed in parallel with the bearing, and magnetic fluid retained by a magnetic circuit formed between the magnet and an outer ring of the bearing so as to seal a space therebetween, and
- a receiver for receiving scattered portions of the magnetic fluid is disposed within a range where a magnetic force of the magnet can act, along a direction to which the magnetic fluid may fly off due to a centrifugal force produced by rotation of the rotor.
A fishing spinning reel, comprising:
- a rotor rotated by rotational operation of a handle to wind a fishing line around a spool;
- a line roller provided on the rotor and configured to guide the fishing line to the spool;
- a support portion rotatably supporting the line roller via a bearing;
- and
- a magnetic seal mechanism for sealing an interior of the bearing,
- wherein the bearing is held so as to be restricted from moving in an axial direction by an inner periphery of the line roller and a locking portion formed on the support portion, and
- a receiver for receiving scattered portions of the magnetic fluid is disposed within a range where a magnetic force of a magnet of the magnetic seal mechanism can act so as to cover the magnetic seal mechanism from a radial outside thereof, the scattered portion being scattered due to a centrifugal force produced by rotation of the rotor.
