A sound generator can be easily attached to a spool, and is excellent in sound generation properties while realizing downsizing and weight reduction. A spool of a fishing spinning reel includes a spool body, a thread formed concentrically with an insertion hole, and a sound generator provided separately from the spool body. The sound generator includes an inner peripheral wall in which the thread screwed into a screwed thread is formed concentrically with the insertion hole, an outer peripheral wall disposed at an interval radially outside of the inner peripheral wall and in which a ratchet groove for sound generation is formed concentrically with the insertion hole, and a bottom wall connecting the inner peripheral wall and the outer peripheral wall. A recess surrounded by the inner peripheral wall, the outer peripheral wall, and the bottom wall is provided.

A line stopper for a fishing reel according to the discloser includes a line stopper member that includes a fishing line catching portion and a support shaft portion, and a supporting member that supports the line stopper member and fits in a through hole formed in a main body of the fishing reel. On one of the fishing line catching portion or the supporting member, a protrusion is provided at a left or right side or both the left and right sides of the support shaft portion in a width direction of the supporting member in a plan view where the fishing line catching portion and the supporting member overlap each other.

A spinning reel includes a reel body, a main shaft, a crank for driving the main shaft to rotate, a tubular worm, a rotor coupled to the tubular worm to rotate therewith, and a speed shift device. The speed shift device includes a shell body configured to rotate with the main shaft, larger-dimension and smaller-dimension output wheels each meshing with the tubular worm, first and second tubular members, and a shifting unit. The shifting unit is configured to transmit rotational force of the shell body to one of the larger-dimension and smaller-dimension output wheels through a corresponding one of the first and second tubular members for driving the tubular worm.

A spool for a spinning reel is mountable on a spool shaft. The spool includes a spool body that rotates with respect to the spool shaft. The spool also includes a drag mechanism between the spool body and the spool shaft to apply a braking force against a rotation of the spool body. The spool further includes a radiator in the spool body and in contact with the drag mechanism. The radiator rotates with respect to one of the spool body or the spool shaft. The radiator does not rotate with respect to the other one of the spool body or the spool shaft.

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 removable reel system includes a frame, a removable frame assembly, and a first spool. The first spool affixed to the frame when the removable frame assembly is coupled to the frame via a locking assembly disposed on the removable frame assembly. The first spool is removable from the frame by disengaging the locking assembly to uncouple the removable frame assembly from the frame. A second spool is attachable to the frame by engaging the locking assembly to couple the removable frame assembly to the frame.

A quick-change spool, includes an exterior, including (i) a spool flange, at a top end of the quick-change spool, (ii) a spool skirt, at a bottom end of the quick-change spool, and (iii) a spool cylinder, between the spool flange and the spool skirt, an interior, including (iv) at least one spool alignment key, on a spool cylinder interior surface, (v) at least one spool torque transfer key, on a spool skirt interior surface, and (vi) at least one spool retention detent, on the spool skirt interior surface. Further, a quick-change spool system, comprises the quick-change spool, and a drag arbor. The quick-change spool and the drag arbor are configured to (a) releasably attached together, through interaction between a spool retention detent and a spool retention recess, and (b) transfer torque between each other when attached together, through interaction between a spool torque transfer key and a spool torque transfer slot.

A fixing structure for line slack prevention to be disposed on a bail support member of a spinning reel for fishing, the fixing structure includes a line slack prevention member having a cylindrical mounting portion to be inserted into a mounting hole on the bail support member and a fin portion extending radially outward from the mounting portion, and an expanding member to be inserted in a through-hole in the mounting portion of the line slack prevention member to fix the mounting portion of the line slack prevention member to the bail support member in an expanded state.
