A line roller includes a cylindrical guide member including a guide surface on an outer perimeter for guiding a fishing line, an axle bearing member rotatably supporting an inner perimeter surface of the guide member, and a support member supporting the axle bearing member. The axle bearing member includes an inner ring supported by the support member, an outer ring integrally rotatable with the guide member, a rolling body disposed between the inner ring and the outer ring, and a grease holding unit holding water-repellent grease between the inner ring and the outer ring.

A line roller for guiding the fishing line onto a spool of a spinning reel for fishing includes a cylindrical guide member including a guide surface for guiding the fishing line on the outer perimeter, an axle bearing member that rotatably supports an inner perimeter surface of the guide member, a support member that supports the axle bearing member, and a grease holding unit that forms a space leading from the axle bearing member to the guide member and that holds a water-repellent grease in the space.

A line roller for guiding a fishing line to a spool of a spinning reel includes a bearing member rotatable about a rotational axis. The line roller also includes a guide member disposed outside the bearing member in a radial direction from the rotational axis. The guide member includes a holding portion and a body. The holding portion is made of a metal or a ceramic. The holding portion is to hold a fishing line. The holding portion extends in a circumferential direction centered about the rotational axis. The body includes a resin, and a guide surface for leading the fishing line to the holding portion.

A spinning reel includes a reel body. The real body includes a lid portion having a fitting recess and a groove. An axle bearing member fits into the fitting recess. The fitting recess includes an inner surface that contacts the axle bearing member and a bottom surface that contacts the axle bearing member. The groove is formed on the inner surface.

In a bearing according to an embodiment, a pair of magnets is arranged such that sides of the magnets opposed to each other with rolling members interposed therebetween have different magnetic polarities from each other. A magnetic fluid sealed bearing according to another embodiment includes a non-magnetic spacer disposed between a magnet of one of magnetic fluid seals and a magnet of the other of the magnetic fluid seals so as to form a magnetic circuit that penetrates outer and inner rings and goes around the rolling members.

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 is configured such that a handle is attachable to and detachable from a reel body. The fishing spinning reel comprises a drive gear shaft that is provided in the reel body, ball bearings that are externally fitted into the drive gear shaft and rotatably support the drive gear shaft, and a handle shaft that is provided in the handle and is screwed into the drive gear shaft. The handle shaft is integrally provided with an abutting portion that abuts on inner rings of the ball bearings by the screwing into the drive gear shaft.

A waterproof spinning fishing reel includes a housing having an accommodation, an opening and an opening edge, a worm located in the accommodation and extending out of the opening, a bushing sleeved onto the worm, a waterproof bearing having a first outer race abutting against the housing, and a first inner race sleeved onto the bushing, a cover having a plate portion mounted to the housing and abutted against the first outer race, a rotor assembly mounted to the worm and provided with an abutment portion abutting against the bushing, an outer seal ring sleeved onto the first outer race and sandwiched between the plate portion and the opening edge, and an inner seal ring sleeved onto the bushing and sandwiched between the abutment portion and the first inner race. This arrangement reduces friction between the rotor assembly and the housing, enhancing smoothness of usage.
