  • Patent number: 9668466
    Abstract: Disclosed is an apparatus for attaching and detaching a cover of a bait casting reel piezoelectric drive circuit. The apparatus includes a reel main body which is formed with an opening portion on one side, and inside which a spool is rotatably installed; a reel cover which supports the rotation of the spool, and opens and closes the opening portion by horizontally moving from one side of the reel main body so that the spool is separated from the reel main body; and a holder which connects the reel main body with the reel cover, projects from the reel main body to guide an opening and closing path of the reel cover when the opening portion is opened, and is coupled with the reel cover by a magnetic body internally provided to fix a separation position of the reel cover.

  • Patent number: 8899505
    Abstract: Disclosed is a fishing reel. A brake dial is provided in the side of an outer cover outside of a spool cover. An externally controllable brake device is provided between the brake dial and the spool cover such that the brake device is operated according to adjustment of the brake dial. A brush-type brake unit is fixed to the externally controllable brake device in the side of an inner surface of the spool cover so as to control the rotary force of the spool while laterally moving in response to actuation of the externally controllable brake device.

  • Patent number: 8695910
    Abstract: A fishing reel has an externally controllable brake system including a brake dial provided on a left side cover outside a spool cover. The brake system is provided between the brake dial and the spool cover so as to externally control a rotary force of a spool. The brake system includes a rotary section rotating together with a rotary motion of the brake dial, and a brake housing provided close to the rotary section so as to laterally slide in response of the rotation of the rotary section, wherein an inner ring is fixed to the brake housing on an inner surface of the spool cover so as to stop the rotary motion of the spool while being guided along the brake housing.
