Abstract: A method for a dual-bearing reel includes detecting a rotational speed of a spool rotatably mounted to a reel unit, a fishing line to be wound about the spool, controlling a spool brake to brake the spool with a first braking force when a detected tension that acts on the fishing line is equal to a reference tension controlling the spool brake to brake the spool with a braking force obtained by correcting the first braking force based on a second braking force when the detected tension and the reference tension are different from each other, the second braking force positively or negatively correcting the first braking force by increasing or decreasing the first braking force, and performing a decrease processing of decreasing the second braking force with the elapse of time when the second braking force has been determined to fluctuate with a predetermined amplitude or greater.

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 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.

Abstract: The spool brake device is equipped with a brake unit, a detector, and a controller. The controller controls the braking force by the brake unit based on the variation of the rotational speed of the spool detected by the detection unit. When the rotational speed is increasing, the controller controls the braking force by the brake unit in the regular braking mode. In the regular braking mode, the controller changes the braking force by the brake unit according to the rotational speed of the spool. In addition to it, when the rotational speed of the spool stops, the controller is to control the braking force by the brake unit in the first braking mode, during a period of predetermined time. In the first braking mode, the controller makes a braking force by the brake unit that is less than the braking force in the regular braking mode. In addition, after the predetermined time, the controller may make a braking force in a second braking mode by the braking unit that is less than the braking force in the first braking mode.
