A spinning fishing reel includes a housing, a line spool reciprocatingly moveable relative to the housing, a rotor rotatable relative to the line spool, a gear disc rotatably mounted inside the housing, and a handle assembly. The gear disc includes a shaft tube, and an internal thread portion and a stop portion both provided at an inner wall of the shaft tube. The handle assembly includes a handle and a drive shaft having a first end pivotally connected with the handle. The drive shaft has an external thread portion engaged with the internal thread portion of the gear disc in a way that the drive shaft is penetrated through an opening of the housing and inserted into the shaft tube of the gear disc, and a second end of the drive shaft is abutted against the stop portion of the gear disc.

A handle operation assist device includes a handle angular velocity measuring unit, an error calculator and a notification unit. The handle angular velocity measuring unit is configured to measure a handle angular velocity based on an output of a sensor configured to detect an angular velocity corresponding to rotation of a fishing reel handle. The error calculator is configured to calculate an error in the handle angular velocity with respect to a reference angular velocity. The notification unit is configured to carry out notification regarding the error.

I provide a braking device attachable to a body frame having one bearing member that pivotally supports a spool and an operation means for rotating the spool, including another bearing member that pivotally supports the spool; a spool brake; a control board that controls the braking force of the spool brake; a battery that supplies power to the control board; and a cover member that covers the battery and the board.

A dual-bearing reel includes a reel body, a spool shaft, a first elastic member, a first shaft bearing, a pinion gear, a pressing member, and a second elastic member. The first elastic member is mounted on the outer circumferential surface of the spool shaft. The first shaft bearing includes an inner race that has an inner circumferential surface that contacts the first elastic member, and an outer race. The pressing member is pressed by the pinion gear in a first direction and approaches a first end when the pinion gear is in the decoupled position. The second elastic member is disposed between the pressing member and the outer race of the first shaft bearing, and the pressing member is pressed by the pinion gear when the pinion gear is in the decoupled position, thereby pressing the outer race of the first shaft bearing in the first direction.

A fishing reel includes a reel body, a first shaft member, a second shaft member, a rolling element, and an outer member. The first shaft member is rotatably supported by the reel body. The second shaft member is connected to an end of the first shaft member in an axial direction of the first shaft member. The second shaft member rotates integrally with the first shaft member. The rolling element contacts the second shaft member in a radial direction away from an axial center of the first shaft member. The outer member is disposed outside the rolling element in the radial direction. The outer member rotates integrally with the second shaft member only in one direction along a circumferential direction around the axial center of the first shaft member.

A dual-bearing reel includes a reel body, a spool rotatably held between side plates, and a brake unit configured to brake the spool. The brake unit includes a cover portion, a first regulator and a second regulator. The cover portion has a first circumferential part and a second circumferential part, and is mounted to the reel body. The first regulator and the second regulator are covered with the cover portion. The first circumferential part has a first opening exposing at least a part of the first regulator therethrough, whereas the second circumferential part has a second opening exposing at least a part of the second regulator therethrough. The reel body has a first restriction part covering the first opening.

One object is to provide a fishing reel including a magnetic fluid sealed bearing wherein foreign substances are shut out from the magnetic fluid seal to prevent degradation of the magnetic fluid (degradation of the magnetic sealing function). In accordance with one aspect, the fishing reel of the present invention includes a magnetic fluid sealed bearing rotatably supporting a drive shaft (pinion). Protection walls are disposed opposite to each other on or near the sides of the bearing body so as to shut out foreign substances from the bearing body of the magnetic fluid sealed bearing.

A support structure for a fishing reel includes a first portion, a second portion, a first shaft bearing and a second shaft bearing arranged side by side in the axial direction along an axis between the outer circumferential surface of the first portion and the inner circumferential surface of the second portion, a spacer disposed between an inner race of the first shaft bearing and an inner race of the second shaft bearing, and a regulating member configured to restrict movement an outer race of the first shaft bearing or an outer race of the second shaft bearing, in a direction in which one of the outer race of the first shaft bearing or the outer race of the second shaft bearing is separated from the other of the outer race of the first shaft bearing or the outer race of the second shaft bearing.

Provided is a magnetic fluid sealed bearing with which torque can be reduced without impairing a water and dust proof effect. A magnetic fluid sealed bearing according to the present disclosure includes a magnetic fluid retained by a ring-shaped magnet in an opening between an inner ring and an outer ring to seal a plurality of rolling members. The magnet is magnetized such that their magnetic poles point to an axial direction. The bearing further includes a ring-shaped outer polar plate and a ring-shaped inner polar plate sandwiching the ring-shaped magnet therebetween, one side of the polar plates being fixed to one of the inner ring and the outer ring, and the other side of the polar plates facing a clearance.
