Japanese Patent Laid-Open No. 7-246045

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

  An object of the present invention is to maintain a high strength while reducing the weight of a rotor.

A spinning reel rotor according to a first aspect of the present invention is a rotor that is rotatably mounted on a reel body and guides fishing line to a spool, and includes a cylindrical portion, first and second rotor arms, and a bale arm. Yes. The cylindrical portion is rotatably mounted on the reel body.

The first and second arm portions each having a tapered shape in which the width, which is the length along the rotation direction of the rotor, becomes narrower as it extends. The bale arm is swingably attached to the tips of both rotor arms. In addition, the outer portion of the second arm portion does not extend in the direction along the rotation plane of the rotor from the outer portion of the second connection portion , and gradually separates from the cylindrical portion as it extends forward and bends in the middle. There is no part .

  The rotor of this spinning reel is formed in a tapered shape in which the two rotor arms extend forward while projecting outwardly from the cylindrical portion, and the width, which is the length along the rotation direction of the rotor, becomes narrower as it extends. ing. For this reason, since there is no bent portion and stress concentration does not occur at that portion, the stress is averaged and the strength can be maintained high without increasing the thickness of the rotor arm. Therefore, the strength can be maintained high while reducing the weight of the rotor.

  A spinning reel rotor according to a second aspect of the present invention is the rotor according to the first aspect, wherein the first and second connection portions are formed smoothly and continuously in the circumferential direction with the cylindrical portion, and the first and second arm portions. Is formed smoothly and continuously with the first and second connecting portions, and extends forward with a spacing from the cylindrical portion. In this case, since the cylindrical portion and the connecting portion, and the connecting portion and both arm portions are formed smoothly and continuously, the stress is less likely to be concentrated in these continuous portions, and the strength can be maintained higher.

A spinning reel rotor according to a third aspect of the present invention is a rotor that is rotatably mounted on a reel body and guides fishing line to a spool, and includes a cylindrical portion, first and second rotor arms, and a bale arm. Yes. The cylindrical portion is rotatably mounted on the reel body. The first and second rotor arms are arranged opposite to each other on the outer peripheral surface of the rear portion of the cylindrical portion, and the first and second connection portions formed smoothly and continuously in the circumferential direction with the cylindrical portion. First and second arm portions having tapered shapes that are formed smoothly and continuously with the cylindrical portion, extend forward and spaced apart from the cylindrical portion, and become narrower in width along the rotational direction of the rotor as it extends. Have each separately. The bale arm is swingably attached to the tips of both rotor arms. In addition, the outer portion of the second arm portion does not extend in the direction along the rotation plane of the rotor from the outer portion of the second connection portion , and gradually separates from the cylindrical portion as it extends forward and bends in the middle. There is no part .

  In the spinning reel rotor, the first and second rotor arms are formed such that the cylindrical portion and the two connecting portions are smoothly and continuously formed in the circumferential direction, and the two connecting portions and the two arm portions are smoothly separated from each other. Since they are formed continuously, the stress concentration between them is reduced, the stress is averaged, and the strength can be maintained high without increasing the thickness of the rotor arm. Therefore, the strength can be maintained high while reducing the weight of the rotor.

  A spinning reel rotor according to a fourth aspect of the present invention is the rotor according to any one of the first to third aspects, wherein at least one of the first and second connecting portions is disposed in the cylindrical portion at a circumferential interval on the rear outer peripheral surface. Of the first arm part and the second arm part, the arm part that is continuous with the two leg parts gathers together at the tip part to support the bail arm in a swingable manner. In this case, since at least one of the two rotor arms has a structure in which the distal end portion is gathered and the proximal end portion is separated in the circumferential direction and divided into two forks, the weight can be further reduced. Moreover, since the base end portion expands in the circumferential direction, the rigidity of the rotor arm in the circumferential direction is increased, and the strength can be maintained higher.

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 yarn 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, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then released vigorously due to the weight of the device. In this state, for example, when the handle 1 is rotated in the line winding direction with the left hand, the rotor 3 is rotated in the line winding direction by the rotor drive mechanism 5 and the bail arm 44 is returned to the line guiding posture by the bail reversing mechanism 46. 4 is wound around.

  When the handle 1 is rotated in the line winding direction, the rotor 3 rotates 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, even if the fishing line is loosened and accidentally entangled with one of the bail support members 40, 42, the rigidity of the rotor arms 31, 32 is maintained high, so that the rotor arms 31, 32 are not easily damaged. In addition, since both the rotor arms 31 and 32 are reduced in weight, when the handle 1 is rotated, it can be rotated with a light force.

[Other Embodiments]
In the above-described embodiment, the second rotor arm 32 is configured by a bifurcated arm portion. However, the first rotor arm 31 may also be configured by a bifurcated arm portion in the same manner as the second rotor arm 32. In this case, the bale reversing mechanism 46 may be provided separately without being provided inside the first rotor arm 31. This improves the rotational balance of the rotor.
