US 6,484,956 B2 · Spinning-reel reciprocating device

Abstract

A dense-winding capable oscillating mechanism that holds down manufacturing costs and ensures easy manufacturing precision. The spinning reel oscillating mechanism (6), for reciprocating the spool back and forth in cooperation with rotation of the handle attached to the reel unit-to which a fishing-line-guiding rotor is rotatively fitted-includes a pinion gear (12), a stepped gear unit (13) and a shifting mechanism (17). The pinion gear (12) rotates in cooperation with handle rotation. The stepped gear unit (13) includes a larger-diameter gear (19) meshing with the pinion gear (12) and a smaller-diameter gear (20) disposed concentric with the larger-diameter gear (19), for rotating unitarily with the larger-diameter gear (19). The shifting mechanism (17) has a driven gear (16) meshing with the smaller-diameter gear (20) and reciprocates the spool by rotation of the driven gear (16).

Dependent claims

A spinning reel reciprocating device for reciprocating a spool back and forth in cooperation with rotation of a handle furnished on a spinning-reel unit to which a fishing-line-guiding rotor is rotatively fitted, the rotation of the handle being transmitted to the rotor via a pinion gear, the spinning reel reciprocating device comprising:

a main gear for rotating together with the rotation of the handle;
a drive gear for rotating in cooperation with rotation of the handle, said drive gear being disposed on an opposite side from said main gear relative to the pinion gear;
a stepped gear unit including a larger-diameter gear having more teeth than said drive gear and meshing with said drive gear, and a smaller-diameter gear disposed concentric with said larger-diameter gear and rotating unitarily with said larger-diameter gear;
and
shifting means having a driven gear meshing with the smaller-diameter gear and a slider that is disposed facing said driven gear and axially immovably coupled to a spool shaft onto which the spool is attached, said shifting means being for reciprocating the spool by rotation of said driven gear, said driven gear having more teeth than said smaller-diameter gear.
