The present invention randomly adjusts the rotational force of the spool by converting and adjusting the interval between the magnet holder with permanent magnet and the steel plate installed in the reel spool according to the adjustment of the adjustment holder installed in one side cover plate of the bait cating reel. The brake device of the bait casting reel for controlling, in particular, facilitates the conversion and adjustment of the magnetic force control distance between the permanent magnet of the magnet holder and the spool iron, and the braking position of the primary adjusted magnet holder can be stably maintained. It relates to a brake unit of a bait casting reel.

The bait casting reel that is generally used requires a braking device to adjust the throwing distance of the fishing line by applying a proper resistance to the fishing line released while the spool is free to rotate.

In this braking system, when the spool is rotated more than a certain speed as the fishing line is released, the centrifugal brake is operated to stop the rotation of the spool, and the brake is directly braked by the rotation of the spool by a tension adjusting nut installed at one side of the spool shaft. Mechanical braking devices such as those having been applied are known.

However, the centrifugal brake device described above is subject to a sudden braking force when the centrifugal brake is operated, and thus not only can the fishing line be thrown away, but also the backlash that occurs when the spool in the rotating state suddenly stops. Due to the difficulty of tangling the fishing line, the braking device by the late tension adjusting nut can easily wear or damage the contact part by the frictional force caused by the direct contact between each member, so that the braking function required for long-term use can be sufficiently exerted. There was a defect such as becoming impossible.

On the other hand, recently, a braking device using a permanent magnet has been proposed and used to solve the difficulties and defects of the mechanical braking device. For example, an adjustment holder exposed through one side cover plate of a bait casting reel. A magnet holder equipped with a permanent magnet inside the spring is elastically installed with a spring, and the inner surface of the adjusting holder and the inclined surface formed to face each other on the outer surface of the magnet holder are in contact with each other. By increasing or decreasing the braking gap between the permanent magnet of the ulder and the steel plate installed on one side of the spool, it is possible to increase or decrease the strength of the magnetic force applied to the steel plate of the spool, or use a separate knob Rotate the holder and the inclined surface formed on the magnet holder protrudes from the inner surface of one side cover plate. The like to be in contact with the inclined contact projections would allow one to adjust the braking distance between the permanent magnet and the spool-side iron plate of the magnet holder is known.

However, in the conventional magnetic braking device having such a structure, since the inclined surface of the magnet holder is required to have a separate spring or adjusting knob gear for intimate contact with the inclined contact portion of the adjusting holder, an increase in required parts and As a result of the cumbersome assembly process, not only the manufacturing cost is increased and the productivity is lowered, but also the magnetic contactor and the adjusting holder or the plate contact protrusions of the side cover are inclined to face each other. There was a problem with the coupling such that the position of the magnetic holder adjusted by the elasticity of the spring to elastically install the magnetic holder or the shock or vibration applied from the outside is easily changed.

Therefore, the main object of the present invention is to provide a brake apparatus of a bait casting reel that does not have the above problems and problems.

Another object of the present invention is that two separate magnet holders operated according to the rotation of the adjustment holder are moved in the radial direction of the adjustment holder, and the permanent magnets of the magnet holder are adjacent to or spaced apart from the cylindrical peripheral wall of the steel plate installed in the spool. This makes it possible to easily adjust and adjust the braking distance between the spool plate of the magnet holder without using a separate spring or the like, and to bait to more reliably and stably maintain the adjustment position of the moved magnet holder. A brake device for a casting reel is provided.

In order to achieve the above object, the brake device of the bait casting reel according to the present invention is configured as follows.

On the inner surface of the adjustment holder exposed through one side cover plate of the bait casting reel main body, an adjustment groove which is eccentric toward the center thereof is formed to face each other, and an operation protrusion fitted to each adjustment groove is formed inside the adjustment holder. Each of them is provided with a fan-shaped magnet holder which can be moved along the radial direction of the adjustment holder by the forward and reverse rotation of the adjustment holder.

Inside the respective magnet holders are provided with a magnet holder support that is fixed between the inner surface of the side cover plate and the outer surface of one side support frame of the reel unit, each guide projection protruding on both sides of the outer surface of the magnet holder support Inserted in the guide groove formed on the inner surface of the magnet holder is assembled so that both the magnet holder can be guided in the radial direction of the spool along the guide projection, several permanent magnets fixed to the outer surface of the bent support portion of each magnet holder It penetrates to the spool side through the through holes formed in the both sides of this magnet holder support.

An iron plate having a cylindrical main wall is fixedly installed on one side of the spool installed inside the magnet holder support, and permanent magnets of the respective magnet holders are disposed at predetermined distances on both sides of the inner circumferential wall of the cylindrical main wall.

The reel brake device according to the present invention configured as described above is moved to the magnet holder with the rotational force according to the rotation adjustment of the adjustment holder, so that the permanent magnet of the magnet holder adjusts the braking distance between the spool side iron plates, and the eccentric adjustment of the adjustment holder. The operation protrusions of the two magnet holders separated into the grooves are inserted into each other, and the guide protrusions of the magnet holder supports are inserted into the guide grooves of the magnet holders to guide the rotational force of the adjustment holders or the spools. Since the required braking distance can be adjusted by changing the linear movement of the magnet holder moving in the radial direction, the gap between the magnet holder and the spool steel plate can be easily adjusted without using a separate spring or adjusting knob gear. Can be converted and adjusted, especially the adjustment position of the primary-adjusted magnet holder does not change arbitrarily. It can be maintained.

Eccentric adjustment grooves 11 and 11 in which the operating projections 21 and 21 of the magnet holders 20 and 20 are close to the center C of the adjustment holder 10 as shown in FIG. 4A. The arcuate support portions 20b and 20b of the magnet holders 20 and 20, and the permanent magnets 22 and 22 installed therein, are located at one end 11a or 11a of FIG. As shown in the drawing, the steel plates installed in the respective permanent magnets 22 and 22 and the spool 2 are in close proximity to the inner edges of the through holes 33 and 33 of the magnet support holder 30. A constant distance D is maintained between the inner surfaces of the cylindrical circumferential wall portion 41 of 40 as shown in FIGS. 3 and 5a, respectively.

Therefore, when the fishing line is released in this state, each permanent magnet 22 provided in the magnet holders 20 and 20 in the cylindrical circumferential wall portion 41 of the iron plate 40 rotated together with the spool 2.
