  • Patent number: 4561605
    Abstract: A fishing reel is provided with a spool and a magnetic brake for reducing overrun of the spool. The spool has a frame member which rotatably supports the spool, a cylindrical electric conductor rotatable together with the spool, and a magnet holder having at least one magnet positioned at one side of the holder radially of the conductor and opposite thereto. The holder has a support unit which supports the holder to the frame member so that the magnet can be adjusted radially toward or away from the conductor to thereby adjust the braking of the conductor. The support means includes a control member which controls the holder to move toward the position where the magnet is adjusted.

  • Patent number: 4544111
    Abstract: A magnetic brake fishing reel is provided which includes a reel body rotatably supporting a spool and a drive mechanism supported to the reel body and having a clutch for releasably driving the spool. The magnetic brake has an electric conductor which is rotatable together with the spool. A magnet holder having at least one magnet is disposed opposite to the conductor. An adjustor which moves the magnet has an operating member positioned such that it is hand-operable by an angler gripping a fishing reel rod on which the reel is mounted.

  • Patent number: 4522354
    Abstract: A fishing reel comprises a spool shaft having a spool and which is supported rotatably between a pair of frames so that the spool shaft is driven through a clutch by a drive mechanism having a drag mechanism and which is provided with a clutch operating mechanism which is operated to disengage the clutch to allow the spool to freely rotate. The drive mechanism is provided at a main gear thereof with a stopper gear rotatable together therewith, one of the frames is provided with a stopper engageable with the stopper gear to impede the reverse rotation of spool, and the frame is provided with an operating segment for the stopper, thereby enabling engagement and disengagement of stopper with or from the stopper gear.

  • Patent number: 4434951
    Abstract: A fishing reel which rotatably supports a spool shaft having a spool to a reel body through a pair of bearings and incorporates, into a bearing housing supporting one of the pair of bearings, a magnetic force brake which imparts a rotational resistance against free rotation of the spool shaft, has the bearing at the bearing housing incorporating the brake formed as a metallic bearing comprising a non-magnetic material.

  • Patent number: 4418877
    Abstract: A fishing reel in which a fishing line can be wound on a spool through rotation of a rotary frame having a bail arm by operating a handle and the wound line can be drawn out of the spool for casting by turning over the bail arm, said spool having a first flange at a side with respect to the reel body, a cylindrical extension extending at the first flange toward the reel body, a third flange provided at the end of the cylindrical extension to thereby form a groove for receiving the fishing line, so that the fishing line, if backlash occurs during casting, can be prevented from falling between and being caught by the spool and the rotary frame.
