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 pumps a spool shaft , to the forward end of which a spool is mounted, back and forth in cooperation with rotation of a handle assembly . The spinning reel oscillation mechanism includes a drive gear , a worm , a driven gear , and a slider . The drive gear is fitted non-rotatably on a master gear shaft. The worm , superficially into which intersecting helical grooves are formed, is disposed paralleling the spool shaft. The driven gear is provided non-rotatably on the worm. Rotation of the drive gear is transmitted to the driven gear . The slider is fitted reciprocatingly in the body of the reel. The slider has an engagement that engages with the helical grooves , and the spool shaft is fitted back-and-forth immovably to the slider
