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 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 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.

Abstract: A dual-bearing reel spool braking device is configured to brake a spool that is rotatably mounted on a reel body by centrifugal force. The dual-bearing reel spool includes at least one brake shoe, a rotating member and a brake drum. The brake shoe is arranged to apply a braking force to the spool. The rotating member is configured to rotate in conjunction with the spool. The rotating member includes a pivot shaft portion and a fixing portion. The pivot shaft portion pivotally supports the brake shoe and that movably supports the brake shoe in an axial direction of the pivot shaft portion. The fixing portion engages the brake shoe and non-pivotally fixes the brake shoe. The brake drum is arranged to selectively contact the brake shoe.

Abstract: A spinning reel has a reel body, a spool shaft, a spool, a spool ring, and a drag knob. The spool ring is disposed on the external radial portion of a front flange of the spool. The drag knob is disposed in front of the spool shaft. As seen from the outside of the spool ring in the radial direction, an angle formed by a tangent line, which passes through a contact point between an external radial portion and a spherical boundary and which is tangent to the spherical boundary, and a straight line, which is orthogonal to the spool shaft and which passes through the contact point, is less than or equal to degrees. The drag knob is disposed inside the spherical boundary.

Abstract: A collar member is used for a spinning reel. The spinning reel has a reel body, a spool shaft that moves in a front-back direction with respect to the reel body, a pinion gear that rotates around the spool shaft, a rotor nut that rotates integrally with the pinion gear, and a bearing that is disposed between the spool shaft and the rotor nut in a radial direction and rotatably supports the rotor nut. The collar member is disposed between the spool shaft and the bearing in the radial direction. The collar member is formed by a resin material that has a linear expansion coefficient of 10×10-6 (1/°C) or more and 50×10-6 (1/°C) or less.

Abstract: A dual-bearing reel includes a reel body, a drive shaft, a roller clutch, and a prevention member. The reel body includes a boss portion. The drive shaft extends through the boss portion and is rotatably supported in the reel body. The roller clutch includes an outer race non-rotatably mounted in the boss portion, an inner race connected to the drive shaft so as to be integrally rotatable, and a rolling element disposed between the outer race and the inner race. The roller clutch prevents rotation of the drive shaft in one direction. The prevention member is mounted on the outer perimeter of the boss portion to prevent radially outward expansion of the boss portion.
