りやすい。ノζカルブレーキ方式では重りの正量に合せ
てブレーキ力を設定しなければならない。Conventionally, a centrifugal brake system or a mechanical brake system has been used as a spool rotation braking device for a fishing reel. Centrifugal brakes use centrifugal force when the spool rotates, but since centrifugal force is proportional to the square of the rotational speed, there is insufficient braking force in the range of high rotational speeds. In the high rotational speed range, the brake force tends to be excessive.With the normal brake system, the brake force must be set according to the correct amount of weight.

用としても十分便用できるように改良したものである。In these methods, a strong braking force is generated while the spool is accelerating immediately after casting, but once the peak rotational speed has passed and the spool enters a deceleration state, the braking force during acceleration shortens the flying distance. The trajectory of this weight draws a parabolic trajectory, and when the trajectory passes the apex and enters a falling state, centrifugal brakes and mechanical brakes are used to prevent backlash due to overrun, but as mentioned above, 7. Parts were becoming loose and the brakes were not working properly.7. As a result of various experiments conducted to improve upon these, a contact magnetic fluid movement device was invented in 2010 for preventing backlash of fishing reels by applying magnetic fluid. "Application No. 58-00595] J. However, these also have limitations for use with large casting reels or body thrust reels, and there is room for improvement. The present invention eliminates these drawbacks. In other words, the rotor directly connected to the spool is connected to the spool.
! J-, a face piece is enclosed, a magnetic field generating yoke using a high-performance magnet (rare earth cobalt magnet or ferrite magnet tongue) is placed on the outside, and the magnetic field generated at the jlJl of the yoke is suppressed. 'nl! 6. The 4W D'i blade according to the present invention is installed on the inner wall of the rotor, which is designed to be able to be used.7. J angle K = 5”-/
1'o6), to create a magnetic field gradient, and convert the buoyant force applied in the direction of the smaller magnetic field into braking force, making it sufficiently convenient for use with large reels.

はJIシもイタした制動力として働く。As a result, buoyancy is generated by the heavy viscosity/high specific gravity magnetic fluid placed in the magnetic field, and the resistance wings of the present invention move against this buoyancy from the low magnetic field to the high magnetic field side fm, resulting in a large resistance force (' lI, IJ power) is generated. This braking force is 1. : Even during instantaneous sudden acceleration, even if you pass the top of the 111 trill path and enter a deceleration state, the Fliυ power proportional to the spool + M1 rotation speed acts smoothly, and the spool

比重・粘度を増加させる性質がある。The magnetic fluid used here is a well-known type of feather material with the most advanced technology, and is a liquid material in which fine powder of magnetic particles is uniformly dispersed in a solvent and coated with a surfactant, and the fluid can freely shape. It is attracted to the abrasive pole while changing its value, and its characteristics as a magnetic material are that as the external vf,'3 increases, its magnetization also increases, which increases the specific gravity and viscosity of the liquid.

It increases the effectiveness of the braking action, prevents troubles due to backlash, and realizes an I-'Ey brake. This is fundamentally different.
