Abstract
A magnetic brake mechanism 22 is disclosed which brakes the rotation of a spool 15 on a double-bearing fishing reel. The brake mechanism 22 includes a flange portion 15a on the end of spool 15, two sets of three magnets 56, and a magnet positioning means 58. The magnetic positioning means 58 variably positions the magnets 56 between a first position, in which the magnets 56 are generally parallel to the surface of the flange portion 15a, and a second position in which the magnets 56 are generally perpendicular thereto. The rotation of the flange portion 15a causes the rotation of the magnetic flux from the magnets 56 to generate an eddy current. As a result, force is applied to the flange portion 15a in the direction opposite its rotation and brakes the rotation of spool 15.
