Description

[Detailed Description of the Invention] In a spinning reel for long distance casting, the fishing line winding body of the spool is tapered, and the fishing line is wound around the spool in a twill pattern so that the winding angle of the fishing line becomes large. The current situation is to reduce the resistance when releasing the fishing line as much as possible.

However, in this conventional method, the fishing line slides toward the small diameter side of the spool, that is, the front side, due to the taper of the spool, and the fishing line is biased toward the front side, causing slack, which increases the resistance when releasing the fishing line. , this tendency becomes even more pronounced when the taper of the spool is increased.

The present invention has been made to improve these deficiencies.In a spinning reel in which a spool shaft is reciprocated by a traverse cam groove and an engager that engages with the traverse cam groove, the pitch of the traverse cam groove is gradually increased toward the rear. The gist is what was formed.

An embodiment of the present invention will be described with reference to the drawings. A shaft cylinder 4 having a rotor 3 having a bail arm 3' fixed to its tip is rotatably supported in the front part of a housing 2 having a reel mounting leg 1. A pinion 5 integrally formed at the base end of the shaft tube 4 is a drive gear 7 of the handle shaft tube 6 rotatably supported by a bearing on the housing 2.
At the same time, an engaging shaft 9 of a handle 8 is inserted into and engaged with the polygonal hole 6' of the handle shaft cylinder 6 so as to be convertible left and right.

Further, a spool shaft 11 having a spool 10 at its tip is fitted into the shaft cylinder 4, and the spool shaft 11 has a spool 10 at its tip.
The fishing line winding body of No. 0 is formed in a tapered shape with a small diameter at the front side and a large diameter at the rear side, while the lower part of the housing 2 has a rotating cam groove 12 parallel to the spool shaft 11 and a traverse cam groove 12. A shaft 13 is supported, and a pinion 14 provided at the tip of the rotating shaft 13 meshes with the pinion 8, and the traverse cam groove 12 is formed such that its pitch gradually increases toward the rear.

A bridge body 15 that fits into the rotating shaft 13 is fixed to the end of the spool shaft 11, and an engaging element 16 that engages with the traverse cam groove 12 is held in the bridge body 15. It is formed so as to slide back and forth on the spool shaft 11 by rotating. In the figure, 17 is a screw for fixing the engagement shaft 9, and 18 is a dustproof cap.

Since the embodiment of the present invention is configured as described above, when the handle shaft cylinder 6 is rotated by the handle 8, the rotor 3 is rotated via the drive gear 7 and the pinion 5, and the pinion 5 further rotates the small gear 14. The rotating shaft 13 is rotated through the traverse cam groove 1.
2 causes the spool shaft 11 to reciprocate and slide by the engaging element 16 that engages with the engaging element 16.

However, in this case, the pitch of the traverse cam groove 12 is formed to gradually increase from the front to the rear, so the fishing line is wound around the spool 10 in a twilled manner, and the front part is coarse and the fishing line becomes denser towards the rear part. It is wrapped in a tapered shape that gradually increases the amount of wrapping.

Note that the above embodiment exemplifies a case in which the traverse cam groove is provided on a rotating shaft separate from the spool shaft to reduce the size of the casing. The spool shaft can also be reciprocated by being provided on the shaft and rotating the engaging element, and the fishing line winding body of the spool does not necessarily need to be tapered and may be a spool of the same diameter.

In the present invention, the pitch of the traverse cam groove for reciprocating the spool is formed so that it gradually increases toward the rear end, so that the amount of fishing line wound around the spool winding body gradually increases from the front side to the rear side. By winding the fishing line in a tapered shape, the resistance when releasing the fishing line can be reduced, making it easier to cast the fishing line over long distances.This eliminates the drawbacks of conventional spools where only the body around which the fishing line is wound is formed into a tapered shape. It has an excellent feature that can prevent.
