DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel for fishing which prevents accumulation of twist in a fishing line winding operation and also reduces damage to the fishing line.

[0002]

2. Description of the Related Art As is well known in the art, a spinning reel for fishing uses a semi-annular bail at the tip of a pair of support arms provided on a rotor and a fishing line discharge position side via a pair of support members. Line rollers for reversing each are mounted on the position side, and a line roller for guiding the fishing line to the spool is rotatably supported by one of the support members.

When the bail is tilted to the fishing line winding position and the rotor is rotated in the fishing line winding direction by operating the handle, the fishing line is wound on a spool that traverses back and forth in conjunction with the rotation of the rotor. When the bail is tilted toward the fishing line discharge position and the device is thrown, the fishing line wound around the spool is fed out in a spiral shape.

Conventionally, in this type of spinning reel for fishing, the position of the line roller relative to the fishing rod guide is limited by the structure in which the line is guided to the spool by a line roller mounted on a rotor that rotates around the spool. The line path in the fishing line guide of the line roller is not stable due to the change, the change in the winding diameter of the fishing line wound on the spool, and the change in the position of the spool that traverses in the front-rear direction. It is known that with the winding of the fishing line, the fishing line moves in the axial direction of the line roller, and the fishing line is twisted.

If the twists accumulate in the fishing line, there is a risk that the yarn will become entangled during the fishing operation, and that a long-term use may cause a problem such as a break in the line. Therefore, in order to solve such a problem, FIGS.
As shown in FIG. 11 , a fishing spinning reel provided with guide circumferential grooves 5, 7 on the outer peripheral surface of the fishing line guide portions 1a, 3a of the line rollers 1, 3 is disclosed in Japanese Utility Model Laid-Open No. 6-46767 and a utility model. Each is disclosed in Japanese Patent No. 3207798.

According to these spinning reels for fishing, the guide circumferential grooves 5 and 7 regulate the unnecessary movement of the fishing line in the axial direction (the direction of the arrow in each drawing) to stabilize the line. Therefore, it becomes possible to reduce the twist of the yarn as compared with the related art.

[0007]

However, in each of the prior arts described above, the guide circumferential grooves 5 for guiding the fishing line to the spool are provided.
Small contact area of the seventh aspect of the, Thus also partly due to the actual winding tension variation of in the fishing line at the time of operation, fishing line joined by local deformation and squeezing in sliding resistance between the side surface, the fishing line However, there is a problem that the service life is shortened due to damage.

The present invention has been devised in view of the above-mentioned circumstances, and a spinning reel for fishing which prevents accumulation of line twist during a winding operation of a fishing line and also reduces damage to the fishing line. The purpose is to provide.

[0009]

In order to achieve the above object, the invention according to claim 1 comprises a line roller provided with a fishing line guide portion on a support member mounted on a support arm of a rotor which rotates in conjunction with a handle. at a rotatably supported fish spinning reel fishing Te, on one side of the fishing line guide portion of the line roller, the guide portion for restricting the movement of the line roller axis direction in the fishing line during winding operation, the line The other side of the roller

It is provided in the form of a plane, and countersunk at the corner of the guide.
From the counterbore, the line guide portion of the line roller,
It is characterized in that the rotor is sequentially formed to have a large diameter in the rotation direction of winding the fishing line .

[0010]

(Action) According to the spinning reel for fishing according to the first aspect, when the bail is reversed to the fishing line winding position and the rotor is rotated in the fishing line winding direction by operating the handle as in the prior art, The fishing line is wound around the spool via the roller. At this time, since the line roller rotates together with the rotor around the spool, a change in the position of the line roller with respect to the fishing rod guide, a change in the diameter of the fishing line wound on the spool, and a traverse motion in the front-rear direction. the influence of changes in the position of the spool, the fishing line is tends to move in the axial direction of the line roller, the fishing line contact surface of the guide portion Ru stabilize the yarn path to regulate the movement of the line roller axis direction of the fishing line . So
The outer diameter of the guide section is smaller than that of the other side of the line roller.

Since the counterbore is provided, the counterbore may cause yarn twisting.
Unnecessary rolling of the fishing line is prevented.

According to the second aspect of the present invention, since the line roller is formed to have a large diameter in the direction of the rotation of the rotor for winding the fishing line, the friction between the line roller and the fishing line is large. Strong on the radial side, as a result, due to the action of its shape, the direction opposite to the rotor winding rotation direction,
That is, a twist in the direction opposite to the twist in the throwing occurs in the fishing line and is wound around the spool. The twist of the fishing line thus generated is canceled out by the twist of the fishing line generated at the time of throwing.

2, a pair of support arms 17, 19 are formed integrally with the rotor 15 in the front-rear direction of the reel body 11, as shown in FIG.

Then, at the tips of the support arms 17 and 19,
A pair of bail support members 21 and 23 are reversibly mounted at a fishing line winding position and a fishing line discharge position, and a semi-annular bail 25 is attached between the two bail support members 21 and 23.
A line roller 27 is rotatably supported by one of the bail support members 21. As shown in FIG. 3, the bail support member 21 includes a bail arm 29 that is reversibly attached to the support arm 17 and a line slider 31 having a substantially T-shaped cross section that functions as a mounting portion for the bale 25. The shaft portion 31a is bolted to the bail arm 29. The ball bearing 33 sandwiched between the shaft portion 31a and the bail arm 29
, The line roller 27 is rotatably supported.

As shown in FIGS. 3 and 4, the line roller 27 has a fishing line guide 27a extending from the bail arm 29 side to the line slider 31 side, that is, the rotation direction of the fishing line winding of the rotor 15 (arrow in FIG. 4). (A direction). Further, the fishing line comes into contact with the periphery of the bail arm 29 side of the fishing line guide portion 27a at the time of the winding operation of the fishing line, thereby restricting its movement in the axial direction of the line roller (in the direction of the arrow in FIG. 4). A substantially disk-shaped guide portion 35 for stabilization is provided integrally. The guide portion 35 has a larger diameter than the other side portion 27b of the line roller 27, and has a structure in which a fishing line contact surface 35a with which the fishing line contacts at the time of the winding operation is formed into a flat shape. .

In FIG. 3, reference numerals 29a and 31b denote annular members for covering the guide portion 35 and the other side portion 27b of the line roller 27 and provided on the peripheral edges of the bail arm 29 and the line slider 31, respectively. With the protrusion, the other side portion 27 of the line roller 27 is compared with the guide portion 35 as described above.

As in the prior art, a spool 37 is mounted on the reel body 11 coaxially with the rotor 15. Although not shown, the spool 37 is attached to the end of a spool shaft which is attached to the reel body 11 so as to be able to traverse. It is screwed through a nut. The reel body 11 is provided with a handle 39 for winding the fishing line.
The rotating shaft and the rotor 15 are connected via a gear mechanism including a well-known drive gear and a pinion (not shown).
The spool shaft is traversed in the front-rear direction of the reel body 11 in conjunction with the rotation of the rotor 15 by a conventionally known traverse mechanism including a slider and a traverse cam shaft fixed to the rear end.

Therefore, similar to the conventional spinning reel,

It is possible to increase the diameter of the spool 37 without causing any problems, thereby taking advantage of the increase in the diameter of the spool, such as an increase in the amount of winding and an improvement in the releasability of the fishing line, while preventing line breakage when the fishing line is released. Further, it is possible to further reduce the size and weight of the reel as a whole. In general, a hard material obtained by subjecting various ceramics or copper alloys to hard plating is often used as the material of the line roller. It is formed of such a hard material.

Since the spinning reel 13 according to the present embodiment is configured as described above, when the bale 25 is tilted to the fishing line discharge position and the device is thrown, the fishing line wound around the spool 37 is fed out in a spiral shape, Since the fishing line winding body portion 37b of the spool 37 is formed in a reverse taper, line breakage of the fishing line at the time of releasing the fishing line is prevented.
