Abstract

Spinning-reel oscillation mechanism employing a compact reel body to achieve dense winding of fishing line onto the spool. The spinning reel oscillation mechanism 6 pumps a spool shaft 15, to the forward end of which a spool 4 is mounted, back and forth in cooperation with rotation of a handle assembly 1. The spinning reel oscillation mechanism 6 includes a drive gear 20, a worm 21, a driven gear 23, and a slider 22. The drive gear 20 is fitted non-rotatably on a master gear shaft. The worm 21, superficially into which intersecting helical grooves 21a are formed, is disposed paralleling the spool shaft. The driven gear 23 is provided non-rotatably on the worm. Rotation of the drive gear 20 is transmitted to the driven gear 23. The slider 22 is fitted reciprocatingly in the body of the reel. The slider 22 has an engagement that engages with the helical grooves 21a, and the spool shaft is fitted back-and-forth immovably to the slider 22.
