Abstract

Simple configuration in a low-gear-ratio type oscillating mechanism for realizing at high transmission efficiency improved lay in the line windings. Spinning reel oscillating mechanism (6), a mechanism that reciprocates the spool (12) in cooperation with rotation of handle (1), is furnished with gear piece (21) and slider (22). The gear piece rotates cooperatively with handle rotation, and is a component on whose one lateral face first and second cam portions (21a), (21b) are formed rim-wise. The slider is attached, immovably in the spool axial direction, at its tip to the rearward end of a spool shaft 20 for the spool, and has: a first cam engager (22a) that extends in a direction intersecting the spool shaft and engages with the first cam, and a second cam engager (22b) that extends in the same direction as the first cam engager and engages with the second cam; and is for reciprocating in the spool axial direction by engagement with either the two cams or the two cam engagers.

Claims20

Dependent claims

A spinning-reel oscillating mechanism for oscillating the spinning reel spool axially in cooperation with handle rotation, the spinning-reel oscillating mechanism comprising:

a rotary member for rotating around an axis approximately parallel to the handle rotational axis, in cooperation with rotation of the handle, said rotary member having;
a first cam provided on said rotary member, and
a second cam, provided on said rotary member, whose diametric position differs at least partially from that of said first cam;
and
a slider member attached, immovably at least in the spool axial direction, rear-endwise to a spool shaft on the fore end of which is the spool, and fitted in the reel body free to shift in the spool axial direction, said slider member having
a through-hole formed thereon,
a first cam engager provided in said through-hole of said slider member, extending in a direction intersecting the spool axis, for engaging said first cam, and
a second cam engager provided in said through-hole of said slider member, extending in the same direction as said first cam engager, for engaging said first cam;
said slider member being oscillated in the spool axial direction by engagement on at least the part of either said first cam and said first cam engager, or of said second cam and said second cam engager.

A spinning reel, comprising:

a reel unit having a handle;
a rotor supported free to rotate on a front of said reel unit;
a spool disposed on a front of said rotor, such that fishing line is wound onto said rotor, said spool being axially movable in cooperation with rotation of said handle;
and
an oscillating mechanism for oscillating said spool axially in cooperation with rotation of said handle, said oscillating mechanism having
a rotary member for rotating around an axis approximately parallel to the handle rotational axis, in cooperation with rotation of the handle, said rotary member having;
a first cam provided on said rotary member, and
a second cam, provided on said rotary member, whose diametric position differs at least partially from that of said first cam;
and
a slider member attached, immovably at least in the spool axial direction, rear-endwise to a spool shaft on the fore end of which is the spool, and fitted in the reel body free to shift in the spool axial direction, said slider member having
a through-hole formed thereon,
a first cam engager provided in said through-hole of said slider member, extending in a direction intersecting the spool axis, for engaging said first cam, and
a second cam engager provided in said through-hole of said slider member, extending in the same direction as said first cam engager, for engaging said first cam;
said slider member being oscillated in the spool axial direction by engagement on at least the part of either said first cam and said first cam engager, or of said second cam and said second cam engager.
