Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotor, and more particularly to a spinning reel rotor rotatably mounted on a reel body for guiding a fishing line to a spool.

[0002]

2. Description of the Related Art Generally, a spinning reel has a reel body having a handle, a spool which is attached to the reel body so as to be movable back and forth, and has a fishing line wound around its outer circumference, and a spool which is rotatably supported by the reel body and has the fishing line wound around the spool. And a rotor. The rotation of the handle is
Normally, it is transmitted to the rotor via a face gear and a pinion gear that meshes with the face gear.

The rotor has a cylindrical portion that is non-rotatably mounted on a pinion gear that is rotatably supported by a reel body, and first and second rotor arms that are arranged to face each other on the outer peripheral surface of the rear portion of the cylindrical portion. A bail arm that is swingably attached to the tips of both rotor arms is provided. Both rotor arms are integrally formed with the cylindrical portion, and extend outward in the radial direction from the cylindrical portion in a trapezoidal shape while smoothly reducing the width, and then bend at about 90 degrees and extend forward.

[0004]

In the conventional rotor, the two rotor arms are both bent from the cylindrical portion and extend forward. Therefore, when a load from the fishing line acts on the rotor arm, stress concentration is likely to occur at the bent portion. In order to maintain high strength so as not to damage the rotor arm even if stress concentration occurs at the bent portion, it is necessary to increase the thickness of that portion. As a result, the mass of the rotor is increased, and it is difficult to reduce the weight of the rotor.

An object of the present invention is to reduce the weight of a rotor and to maintain its high strength.

The two arm portions are formed smoothly and continuously with the first and second connecting portions, and extend forward with a space from the cylindrical portion. In this case, since the cylindrical portion and the connecting portion and the connecting portion and the both arm portions are smoothly and continuously formed, stress is less likely to be concentrated at these continuous portions, and the strength can be maintained higher.

A spinning reel rotor according to a third aspect of the present invention is the rotor according to the first or second aspect of the present invention.
The two arm portions are respectively outward from the first and second connecting portions.
It curves forward and extends forward. In this case, two
While the rotor arm of the
It is formed to extend in one direction. For this reason, the bent part
Disappears and stress concentration does not occur in that part, so
Force is averaged out without increasing the thickness of the rotor arm
High strength can be maintained. Therefore, reduce the weight of the rotor
The strength can be maintained higher while aiming.

A rotor for a spinning reel according to a fourth aspect of the present invention is the rotor according to any one of the first to third aspects,

The outer peripheral surface of is also formed in an arc shape centered on the axis of the spool shaft 15.

In the thus constructed rotor 3, since the rotor arms 31 and 32 are formed so as to be convexly curved outward, there is no bent portion, and stress concentration does not occur at that portion. Therefore, the stress is averaged and the strength can be maintained high without increasing the thickness of the rotor arm.
Therefore, the strength of the rotor 3 can be kept high while the weight of the rotor 3 can be reduced. Moreover, the cylindrical portion 30 and both connecting portions 31a, 32
a and both connection parts 31a, 32a and both arm parts 31b, 3
Since 2b and 2b are formed smoothly and continuously, stress is less likely to be concentrated even in their continuous portions, and the strength can be maintained higher. Further, the second rotor arm 3
Since the two distal end portions are gathered and the base end portions are separated from each other in the circumferential direction to be bifurcated, the weight can be further reduced. Also,
Since the base end portions of both rotor arms 31 and 32 expand in the circumferential direction, the rigidity of the rotor arms in the circumferential direction also increases, and the strength can be maintained higher.

A bail 43 formed by bending a wire into a substantially U-shape is fixed between the tip of the fixed shaft cover 47 and the second bail support member 42. These first and second bail support members 40, 42, line roller 41, bail 4
The bail arm 44 that guides the fishing line to the spool 4 is constituted by 3 and the fixed shaft cover 47. Bale arm 4
4 is swingable between the yarn guiding posture shown in FIG. 3 and the yarn releasing posture reversed from the posture.

A cover 45 is mounted on the outer peripheral side of the first bail support member 40, and the bail arm 44 is returned to the inside of the cover 45 from the yarn releasing posture to the yarn guiding posture in association with the rotation of the rotor 3. At the same time, a bail reversing mechanism 46 that holds the state in both postures is arranged. Inside the cylindrical portion 30 of the rotor 3, a reverse rotation preventing mechanism 50 for inhibiting / releasing reverse rotation of the rotor 3 is arranged. The reverse rotation preventing mechanism 50 has a roller type one-way clutch 51 in which the inner ring rotates freely, and a switching mechanism 52 for switching the one-way clutch 51 between an operating state (reverse rotation prohibiting state) and a non-operating state (reverse rotation permitting state). There is.

The spool 4 is arranged between the first rotor arm 31 and the second rotor arm 32 of the rotor 3, and is attached to the tip of the spool shaft 15 via the drag mechanism 60. The spool 4 has a bobbin trunk 4a around which fishing line is wound, a skirt 4b integrally formed at the rear of the bobbin trunk 4a, and a flange plate 4c fixed to the front end of the bobbin trunk 4a. ing. Bobbin trunk 4a
Is a straight cylindrical member, the outer peripheral surface of which is parallel to the spool shaft 15. Bobbin trunk 4
The a is rotatably mounted on the spool shaft 15 by two bearings 56 and 57. The flange plate 4c is fixed to the bobbin trunk 4a by a spool ring collar 55 screwed to the inner peripheral surface of the bobbin trunk 4a.

[Reel Operation and Operation] At the time of casting, the bail arm 44 is reversed to the line releasing posture with the handle 1 mounted at the left position shown in FIG. As a result, the first bail support member 40 and the second bail support member 42 swing. In this state, cast the fishing rod while hooking the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously due to the weight of the tackle. In this state, when the handle 1 is rotated with the left hand in the line winding direction, the rotor driving mechanism 5 rotates the rotor 3 in the line winding direction, the bail arm 44 is returned to the line guiding posture by the bale reversing mechanism 46, and the fishing line is spooled. It is wrapped around 4.

When the handle 1 is rotated in the line winding direction, the rotor 3 is rotated in the line winding direction via the face gear 11 and the pinion gear 12, and the fishing line guided by the bail arm 44 is wound around the outer periphery of the spool 4. In such a case, the fishing line is slackened and the bail support members 40, 4
Even if the rotor arms 31 and 32 are entangled with one of the two, the rigidity of both rotor arms 31 and 32 is maintained high, so that both rotor arms 31 and 32 are less likely to be damaged. Moreover, since both rotor arms 31 and 32 are made lightweight, the handle 1 can be rotated with a light force.

[Other Embodiments] In the above-described embodiment, the second rotor arm 32 is composed of a bifurcated arm portion, but the first rotor arm 31 is also a bifurcated arm portion like the second rotor arm 32. You may comprise.
In this case, the bail reversing mechanism 46 is connected to the first rotor arm 31.
It may be provided separately without being provided inside. This improves the rotational balance of the rotor.
