Abstract: A dual-bearing reel spool brake device configured to brake a spool being rotatably mounted to a reel unit by centrifugal force is provided. The dual-bearing reel spool break device includes a rotary member, a brake shoe, and a brake drum. The rotary member is configured to be rotated in conjunction with at least rotation of the spool in a fishing-line releasing direction. The brake shoe is elastically engaged with the rotary member, wherein the brake shoe is pivotable and detachable with the rotary member. The brake drum is disposed radially inwards or radially outwards of the brake shoe, wherein the brake drum has a peripheral surface contactable with the brake shoe.

Abstract: A spinning reel includes a spool shaft movable in a front-rear direction with respect to a reel body, a spool connected to the spool shaft and configured to have a fishing line wound therearound, a pinion gear supported by the reel body so as to be rotatable, a reciprocating mechanism configured to move the spool shaft in reciprocating fashion in the front-rear direction, and an intermediate gear disposed between the pinion gear and the reciprocating mechanism, the intermediate gear reducing rotation of the pinion gear, and transmitting rotation to the reciprocating mechanism. A value obtained by dividing a stroke distance of the spool shaft by a winding pitch of the fishing line and a module (M) of the intermediate gear is greater than or equal to 60, the module (M) being a diameter of a pitch circle relative to a number of teeth of the intermediate gear.

Abstract: A reel braking adjustment device includes a tensile force-related information acquisition unit and a braking parameter correction unit. The tensile force-related information acquisition unit is configured to acquire tensile force-related information. The tensile force-related information is information that is related to tensile force acting on a fishing line and detected during a fishing line discharge period in which the fishing line is released from a dual-bearing reel configured to brake rotation of a spool based on a braking parameter. The braking parameter correction unit is configured to correct braking parameters based on temporal changes in the tensile force-related information acquired by the tensile force-related information acquisition unit.

Abstract: A spool of a dual-bearing reel includes a bobbin trunk, first and second flange portions and cylindrical portions. The first flange portion extends outwardly from the first end of the bobbin trunk and the second flange portion extends outwardly from the second end of the bobbin trunk. The first and second flanges do not have through-holes penetrating therethrough in an axial direction. The cylindrical portions extend outwardly from distal end portions of the flange portions. The first and second flange portions have a first tapered portion and a second tapered portion, respectively, each of the first and tapered portions becoming thinner in a radially outward direction. An average width between the first and tapered portions is less than or equal to 60% of an outer diameter of the cylindrical portion.

Abstract: A dual-bearing reel includes a cover and a dial disc including an engagement groove having a first radius centered on the central shaft, and capable of adjusting a braking force of the spool is formed. A projection is fixed to a first side plate, and engages the engagement groove when the cover covers the first side plate. A guide groove is formed on the dial disc, which extends in a direction that is different from that of the arc of the engagement groove and is in communication with the engagement groove, and through which the projection is capable of passing and being detached from the dial disc. The projection is configured to be detached from the dial disc through the guide groove when the intersection point between the engagement groove and the guide groove is aligned with the projection and when the cover covers the first side plate.

Abstract: A fishing reel forwardly releases a fishing line and includes a reel unit, a spool, a spool brake, an electric component, and a voltage booster circuit. The spool is rotatably supported by the reel unit. The spool brake generates an electric power upon a rotation of the spool, and applies a brake force to brake the spool using the electric power when the spool is rotated. The electric component operates using the electric power generated by the spool brake. The voltage booster circuit increases a voltage supplied to the electric component.

Abstract: A spool brake device for a dual-bearing reel, the spool brake device includes a spool brake, a rotation detector, and a spool controller. The spool brake can electrically brake a spool during a releasing of a fishing line by applying a braking force to the spool. The rotation detector can electrically detect a rotation of the spool. The spool controller can determine whether a terminal tackle has landed on water based on an output from the rotation detector after a starting of a casting, and can control the spool brake such that the braking force is maintained at a magnitude when a determination that the terminal tackle has landed on water, the magnitude equal to a magnitude of the braking force at a point of time the determination is made that the terminal tackle has landed on water.

Abstract: A spool brake device for a fishing reel includes an electric spool brake, a rotation detector, and a controller. The rotation detector detects a rotation of the spool. The controller calculates a rotational velocity of the spool based on the rotation of the spool, determines whether the fishing reel is in a casting state based on the rotational velocity, controls the spool brake to brake the spool upon a determination that the fishing reel is in the casting state, and controls the spool brake to not brake the spool upon a determination that the fishing reel is not in the casting state.

Abstract: A clutch mechanism includes a clutch portion and a pinion gear. The pinion gear has an engaging part and a gear part. The engaging part is located on a first end as a spool-side end of the pinion gear and is capable of being engaged with the clutch portion. The gear part is meshed with the drive gear. The gear part has helical teeth enabling the pinion gear to be urged toward the spool by the drive gear. The engaging part has a bottom and a first wall. The first wall extends from the bottom toward the first end and tilts in the same direction as the helical teeth with respect to the spool shaft such that the pinion gear is urged oppositely to the spool by the clutch portion when the engaging part is engaged with the clutch portion and receives transmission of rotation in a fishing-line releasing direction from the spool.
