Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double-bearing reel, and more particularly to a double-bearing reel in which a spool shaft having a spool in the reel body is supported so as to be freely rotatable via a pair of bearings.

Generally, a double-bearing reel has a clutch, and when the clutch is engaged, the rotation of the handle shaft is transmitted to the spool shaft to wind the fishing line onto the spool, and when the clutch is disengaged, the spool shaft rotates freely. The casting operation is similar to casting a fishing line.

By the way, during casting, the fishing line wound around the spool is pulled out by the weight of the device attached to the tip of the fishing line, but the free rotation of the spool becomes faster than the pulling out speed of the fishing line, resulting in what is called backlash. This causes the fishing line to become tangled or get caught between the spool and the reel body, and for this reason, a brake is generally provided.

Further, as the brake, a centrifugal brake using a brake shoe is generally used. According to this centrifugal brake, the brake shoe is brought into sliding contact with the brake drum to perform braking, so that the friction of the brake shoe is reduced. There was a problem that the braking force changed due to various reasons.

However, in order to solve the above problems, a magnetic brake equipped with a magnet and an electric conductor is used, and one of the magnet and the electric conductor in this magnetic brake is made to rotate together with the spool, and the other is attached to the reel body. fixed, one rotation rotates the magnetic flux to generate an eddy current, and according to Fleming's left-hand rule, a force is applied to the rotating member in the opposite direction to the rotational direction of the spool, so as to brake the spool, and , the fixed side member is movable with respect to the reel body,
A double-bearing reel has been proposed in which the relative position of the magnet and the electrical conductor is adjusted by operating an adjustment body provided axially outward of the spool.

Since there are no contact parts with this method, it is possible to solve the problem of the braking force changing due to wear of the braking member, and the braking force can be adjusted by operating the adjustment body, and the braking force is controlled by the number of revolutions of the spool. However, even if the braking force is adjusted by operating the adjustment body, it is not possible to adjust the rate of change in the braking force with respect to the spool rotation speed, and therefore the braking force cannot be adjusted in proportion to the change in the spool rotation speed. Therefore, the braking force cannot be adjusted. That is, for example, if the braking force that is pre-adjusted before casting is set to be larger than the spool rotational speed at which buck crash occurs, buck crash will be less likely to occur;
At the beginning of casting, an even greater braking force acts on the spool, which shortens the throwing distance of the fishing line, and the braking force is set to the minimum value for the spool rotation speed at the beginning of casting. This allows you to throw the fishing line longer, but on the other hand,
There was a problem in which bumps were likely to occur.

The present invention was invented in view of the above-mentioned problems.The purpose of the present invention is to be able to adjust the braking force to suit the angler's preference before casting, to extend the casting distance of the fishing line, and to make it easy to use during casting. The object of the present invention is to provide a double-bearing reel that can reliably prevent backlash by performing certain operations.

That is, the basic idea of the present invention is to be able to adjust the braking force, which increases or decreases in accordance with the rotational speed of the spool. The double-bearing reel is equipped with a magnetic brake, and is provided with an adjustment body for adjusting the braking force of the brake, and a hand that grips the fishing rod to which the reel body is attached is connected to the adjustment body from the adjustment body. The device is characterized by providing an operating body that extends to a position where it can be operated and has an operating section at its tip.
