ている。 The above-mentioned backlash prevention device has magnets arranged on both sides of a conductive ring fixed to the spool shaft, and controls the magnetic field by rotating one of the magnets to displace the magnetic pole, thereby adjusting the braking force of the spool. Utility Model Application No. 57-31175 is known as having such a structure.

難であつて、制動力が急激に変化する難点を有し
ている。 Furthermore, although the above-mentioned magnet is formed to be rotated by an adjustment lever, etc., according to the conventional backlash prevention device, due to its mechanism, the rotation angle of the magnet is large relative to the rotation angle of the adjustment lever, and the interlocking operation by gears is difficult. By doing this, the rotatable magnet ring rotates in proportion to the rotational angular velocity of the adjustment lever, making it difficult to finely adjust the magnetic field control and causing sudden changes in braking force. It has its drawbacks.

るバツクラツシユ防止装置を得たものである。 Therefore, as a result of studies in view of the above-mentioned conventional difficulties, the present invention has been developed by making the ratio of the rotation radius of the magnet ring rotated by the cam groove of the adjustment lever smaller than the rotation radius of the movable magnet ring on the adjustment lever side. In particular, by being configured to adjust the rotation, the rotation angle of the magnet ring with respect to the rotation angle of the adjustment lever can be made small, and the magnetic poles of the outer magnet ring and the inner magnet ring can be changed from S pole to S pole or S pole to N pole. The object of the present invention is to provide a backlash prevention device which is capable of moving quickly at both ends where the two ends meet, and slowly at an intermediate point, thereby making it possible to finely adjust magnetic field control.
