摘要： A spinning reel includes a spool shaft, a handle, a pinion gear, a first intermediate gear, a second intermediate gear, and a reciprocating mechanism. The first intermediate gear is rotatably disposed around a first shaft parallel to the spool shaft. The first intermediate gear includes a first large-diameter gear which meshes with the pinion gear and a first small-diameter gear which integrally rotates with the first large-diameter gear. The second intermediate gear is rotatably disposed around a second shaft parallel to the first shaft. The second intermediate gear includes a second large-diameter gear which meshes with the first small-diameter gear and a second small-diameter gear which integrally rotates with the second large-diameter gear. The reciprocating mechanism includes a driven gear which meshes with the second small-diameter gear and reciprocates the spool shaft in the front-rear direction.

摘要： A spool brake device for a fishing reel includes a velocity detector, a spool controller and a spool brake. The velocity detector is configured to detect a rotational velocity of a spool. The spool controller includes an acceleration generator, an acceleration determiner and a brake time predictor. The accelerator generator is configured to generate time-series data of a rotational acceleration based on the rotational velocity. The acceleration determiner is configured to determine whether the rotational acceleration has satisfied a predetermined condition based on the time-series data of the rotational acceleration. The brake time predictor is configured to set a prediction starting time based on a point of time at which the rotational acceleration has satisfied the predetermined condition and to predict a brake starting time of the spool based on the prediction starting time. The spool brake is configured to start braking the spool at the brake starting time.

摘要： 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.

摘要： A spool brake device is configured to brake a spool capable of winding thereabout a fishing line having a terminal tackle. The spool brake device includes a spool braking part, a spool controlling part, a rotational speed detecting part, and a water landing determining part. The spool braking part is configured to electrically brake the spool in releasing the fishing line. The rotational speed detecting part is configured to detect a rotational speed of the spool. The water landing determining part configured to brake the spool in a predetermined timing after starting of casting with a braking force greater than a predetermined braking force, and to determine whether or not the terminal tackle is in a water landing state in accordance with a detection result of the rotational speed after releasing of braking. The water landing state indicating that the terminal tackle is in water.

摘要： A dual-bearing reel includes a reel body, a spool and a waterproof member. The reel body includes a first side plate and a second side plate. The spool includes a bobbin trunk and a first flange. The bobbin trunk is rotatably disposed between the first side plate and the second side plate. The first flange is provided on a first side plate-side end of the bobbin trunk and has a larger diameter than the bobbin trunk. The waterproof member has an annular shape and is disposed in a first side plate-side position in the reel body. Additionally, the first flange includes a rib having an annular shape. The rib extends axially outward from the first flange and has a smaller diameter than an outermost diameter part of the first flange. The waterproof member is disposed in adjacent opposition to an inner peripheral surface of the rib of the first flange.

摘要： A dual-bearing reel is attachable to a fishing rod and releases a fishing line forward. The dual-bearing reel includes a reel unit, a spool for winding the fishing line, a handle and a level wind mechanism. The spool is rotatably disposed in the reel unit. The handle is rotatably disposed on a lateral part of the reel unit. The level wind mechanism uniformly winds the fishing line onto the spool. The level wind mechanism includes a worm shaft, a guide member and a slide member. The worm shaft includes a helical groove. The guide member is disposed on an outer peripheral side of the worm shaft, and includes an opening and at least one water drain. The opening extends in a lengthwise direction of the worm shaft. The slide member slides along the guide member while engaged with the helical groove.

摘要： The present spool brake device is configured to brake a spool, rotatably mounted to a reel unit, by a centrifugal force. The present spool brake device includes a rotary member, a brake drum and a brake shoe. The rotary member is configured to be rotated in conjunction with a rotation of the spool. The brake drum is disposed in an alignment with the spool along a rotational axis of the spool and is mounted to the reel unit. The brake shoe is contactable to an outer periphery of the brake drum and is pivotably supported by the rotary member, with a center of gravity of the brake shoe being located radially outside the brake drum.
