Abstract

A braking device of a double bearing reel according to one embodiment of the present disclosure brakes a spool rotatably mounted on a reel body, the braking device provided with a braked unit attached to the spool, a braking unit that applies a braking force to the braked unit, an output shaft that adjusts the braking force of the braking unit according to a rotational angle, a motor capable of driving the output shaft in forward and backward directions, a reduction mechanism that transmits power while decelerating from the motor to the output shaft, a control unit that controls the motor, and a power supply that supplies electric power to the motor, the braking device provided with a watertight case that houses the motor, the reduction mechanism, the control unit, and the power supply in a watertight manner, and a waterproof unit for waterproofing on the output shaft.

First claim

What is claimed is:

1. A braking device of a double bearing reel that brakes a spool rotatably mounted on a reel body of the double bearing reel, the braking device comprising:
a braked unit attached to the spool;
a braking unit that applies a braking force to the braked unit;
an output shaft that adjusts the braking force of the braking unit according to a rotational angle;
a motor capable of driving the output shaft in forward and backward directions;
a reduction mechanism that transmits power while decelerating from the motor to the output shaft;
a control unit that controls the motor; and
a power supply that supplies electric power to the motor,
the braking device of the double bearing reel provided with:
a watertight case that houses the motor, the reduction mechanism, the control unit, and the power supply in a watertight manner; and
a waterproof unit for waterproofing on the output shaft.

2. The braking device according to claim 1 , wherein the braked unit is a conductor, and the braking unit is a magnetic circuit formed of a permanent magnet, and the output shaft changes a magnetic field to the conductor by moving at least a part of the magnetic circuit.

3. The braking device according to claim 1 , wherein the braked unit is a frictional member, the braking unit is a frictional braking unit that transmits a contact force to the frictional member, and the output shaft changes a contact force according to rotation.

4. The braking device according to claim 1 , wherein the watertight case further houses at least any one of a rotation detection unit that detects rotation of the spool, a position detection unit that detects a position of a reduction gear of the reduction mechanism, or a clutch state detection unit that detects a state of a clutch of the fishing reel.

5. A fishing reel comprising:
the braking device according to claim 1 .
