  • Patent number: 7721986
    Abstract: A fishing spinning reel of the invention includes a spool wound with a fish line, a rotor rotatable through a pinion gear brought in mesh with a drive gear rotated by a winding operation of a handle, a switch mechanism including a switch lever capable of operating to switch a restricting state of restricting rotation of the spool and a free state of making the spool free, and a return mechanism for returning the switch mechanism brought into the spool free state to the restricting state by the winding operation of the handle. The return mechanism includes a connecting gear brought in mesh with a gear driven by the drive gear, and a kick member rotatably supported centering on the connecting gear, and a center of a mesh portion of the gear and the connecting gear is arranged on a side of the drive gear relative to an axis center of the pinion gear.

  • Patent number: 7631829
    Abstract: A fishing reel according to the invention has a magnetic braking device which includes an electrically conductive body supported so as to move in an axial direction with respect to a spool shaft, on one side of a spool, a magnet which is provided on a reel body and arranged so as to be opposed to the electrically conductive body in a radial direction, and centrifugal collars which move in the radial direction along with rotation of the spool, and allow the electrically conductive body to enter into and retreat from a magnetic field of the magnet, by an engaging action with the spool thereby to increase and decrease a magnetic braking force to be exerted on the spool. The fishing reel is characterized by further including an axial movement holding mechanism for holding the magnet so as to move in the axial direction.

  • Publication number: 20090166458
    Abstract: A fishing spinning reel includes a bail support member having a line guide portion which is supported in such a manner as to rotate reversibly between a line winding position and a line releasing position on an arm portion of a rotor linked with a handle provided on a reel main body in such a manner as to rotate as a result of the handle being operated to turn, and a switching lever which can be switched between an anti-reverse state in which the rotor is prevented from rotating backwards and a rotation enabling state in which the rotor is enabled to rotate forwards and backwards. The bail support member is restricted from reversing from the line winding position to the line releasing position when the switching lever is in the rotation enabling state.
