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.

Spool brake device

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 rotational speed of the spool detected by the detector. When the rotational speed is less than the predetermined rotational speed, 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. On the other hand, when the rotational speed is equal to or higher than the predetermined rotational speed, the controller controls the braking force by the brake unit in the emergency braking mode, during the period of predetermined time. In the emergency braking mode, the controller makes the braking force by the brake unit larger than the braking force in the regular braking mode.

A spool for a dual-bearing reel includes a bobbin trunk having a tubular shape, a pair of flanges and a plurality of first through holes. Each flange is provided on opposite ends of the bobbin trunk, each flange having a circular shape and a larger diameter than the bobbin trunk. The first through holes are provided in at least one flange of the pair of flanges and are circumferentially disposed at intervals about the at least one flange. The first through holes open in a radial position located at a distance away from an outer peripheral surface of the bobbin trunk, the distance being less than or equal to a second distance from the outer peripheral surface of the bobbin trunk, the second distance being 60% of a distance from the outer peripheral surface of the bobbin trunk to an outer peripheral surface of the at least one flange.

Spool for dual-bearing reel

A dual-bearing reel includes a reel body and a spool. The reel body includes a spool housing portion having an inward opening. The spool includes a first flange that has a larger diameter than a bobbin trunk. The outer peripheral part of the first flange includes a first and second outer peripheral parts, and a connecting portion. The first outer peripheral part is disposed at a first prescribed distance away from an inner peripheral part of the first spool housing portion. The second outer peripheral part is disposed at a second prescribed distance away from the inner peripheral part and has a smaller diameter than the first outer peripheral part. The diameter of the connecting portion gradually increases from the second outer peripheral part toward the first outer peripheral part and couples the first outer peripheral part and the second outer peripheral part.

Dual-bearing reel

The present dual-bearing reel includes a first reel body, a second reel body, a first bearing member, a second bearing member, a spool, a spool shaft and a first urging member. The first bearing member is attached to the first reel body. The second bearing member is attached to the second reel body. The spool shall has a first protruding part. The first protruding part radially protrudes between the first bearing member and the second bearing member. The spool shaft is supported by the first and second bearing members. The urging member urges the first protruding part and the first bearing member in opposite directions.
