ABSTRACT:
A backlash prevention adjustment mechanism for a backlash prevention device includes a first magnet, a second magnet, and a nonmagnetic electroconductive member provided therebetween, being rotatable with a spool shaft, and having an eddy current induced therein by the first and second magnet to provide a braking force for the spool to prevent backlash. A motor is provided to move the first magnet relative to the second magnet to change the level of the eddy current. A lever is also provided to manually move the first magnet with respect to the second magnet. In another aspect, a shielding yoke is provided on the first magnet and is movable therewith to position a slit in the yoke proximate a first magnetism sensor or a second magnetism sensor to detect positions thereof corresponding to maximum and minimum levels of the eddy current.
