[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool for winding a fishing line at a front portion of a reel body, a rotor rotating by a winding driving force, and a line formed on an arm formed on the outer periphery of the rotor. The present invention relates to a spinning reel which forms a guide portion and winds a fishing line guided by the line guide portion at the time of rotation of a rotor around a spool. The present invention relates to a spinning reel for reciprocating the fishing line and winding a fishing line on a spool on average.

[0002]

2. Description of the Related Art As a spinning reel configured as described above, there is a spinning reel disclosed in Japanese Utility Model Laid-Open Publication No. 3-99959. In this conventional example, a helical shaft having a posture parallel to a spool shaft and a helical shaft A mechanism comprising an engaging piece engaged with the spiral groove is disposed outside the reel body at a position close to the spool shaft (inside the rotor), and a driving force from this mechanism is supported at both ends of the bail. , And the yarn guide section.

[0003]

In the above-mentioned conventional example,
A mechanism for operating the thread guide in the front-rear direction is arranged outside the reel body, so that the reel body has a good surface that can be downsized. Since a mechanism to operate is arranged,
The size of the rotor in the front-rear direction, especially the distance between the reel body and the spool, is increased, and an operating space for a member for transmitting power from the mechanism for reciprocating the yarn guide to the yarn guide is required inside the rotor. Therefore, the size of the entire rotor cannot be reduced, and improvement is desired.

Further, in this configuration, the size of the member for transmitting the driving force from the above-described mechanism to the yarn guiding portion (the size in the radial direction around the rotation axis of the rotor) becomes large.
When the tension acting on the fishing line is large, the position of the line guide is not determined due to the elastic deformation of the member, causing a deviation in the winding position of the line with respect to the spool. Is also conceivable.

For the purpose of solving this inconvenience, a structure in which only the yarn guide portion is operated back and forth can be considered. However, since the yarn guide is formed at a position relatively separated from the rotation axis of the rotor, this structure is employed. Is adopted, it often leads to a dynamic imbalance of the rotor, and furthermore, in such a configuration in which the line guide is operated back and forth, the weight of the line guide is displaced back and forth during the winding operation of the fishing line. As a result, it is conceivable that the balance state is lost and the rotor is vibrated to deteriorate the operability, and there is room for improvement.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a spinning reel that can be reduced in size and that can be smoothly wound up without generating vibration when the rotor rotates.

[0007]

As described at the beginning, a feature of the present invention is that a spool for winding a fishing line and a rotor rotating by a winding driving force are arranged at a front portion of a reel body. And a spinning reel configured to form a line guide on an arm formed on the outer periphery of the rotor and wind a fishing line guided by the line guide during rotation of the rotor around a spool. A reciprocating mechanism for reciprocating the thread guide in the direction along the axis of the spool in conjunction with the outer periphery of the rotor, and the weight of the spool in the axial direction associated with the reciprocation of the thread guide; There is provided a balance means for canceling the deviation to suppress the generation of the moment when the rotor rotates, and its operation and effect are as follows.

[0008]

According to the above feature, since the reciprocating mechanism is provided on the outer periphery of the rotor, even if the reciprocating mechanism is relatively large, this mechanism is arranged at a position where interference with the spool is avoided and the spool is reeled. It can be arranged at a position close to the main body side, and there is no need to arrange the operation area of the member that links the reciprocating mechanism and the yarn guide at a position where it interferes with the spool. In this case, the balance means and the weight of the yarn guide are offset corresponding to the yarn guide, thereby suppressing the generation of moment.
That is, in the present invention, compared with the conventional example, the spool can be brought closer to the reel body side to reduce the size of the entire reel, and the rotor can be vibrated regardless of the position of the thread guide. Does not occur.

According to the second aspect, since the rotation of the rotor is balanced by the balance structure, the generation of the moment is suppressed. As a result, the vibration at the time of winding the fishing line is further reduced together with the suppression of the moment during the rotation of the rotor by the balance means. It will suppress it. That is, since the balance of the rotor and the balance of the system of the yarn guide portion can be obtained independently, a highly accurate balance state can be realized.

Further, as an example of the equilibrium structure according to claim 2,
5 and 10, the virtual planes S and T perpendicular to the axis X are assumed at two positions in the direction of the axis X of the rotor 4, and a pair of arms 4
In order to cancel the moment at the point P _{S where} the resultant moment of the rotor components except A and 4A acts, the shaft center X
A pair of arms 4A, 4A are arranged so that a moment acts on a point Q _S opposite to the point P _S with respect to the point P _S, and the rotor configuration including the weight of the pair of arms 4 A, 4 A with respect to the virtual plane T In order to offset the moment at the point _{PT where} the resultant moment of the member acts, the point P
To moment acts on _T and opposing point Q _T, by providing the balancer 34, a virtual plane S, the result of balanced in T each occurrence moments during rotation of the rotor is suppressed.

According to the third aspect, the bail, the driven member, and the like are integrally reciprocated in conjunction with the reciprocating operation of the yarn guide, so that the weight of the yarn guide can be reduced without forming a drive system for performing the reciprocating operation. Is offset by the weight of the driven member, and the moment when the rotor rotates can be reduced.

[0012] That is, when mentioned the arrangement of Figure 11 as an example of the balancing means of the third aspect, in order to offset the moment in P _U that acts moments veil 3, the point P across the axial X to act moment in Q _U that faces the _U, the yarn guide section a, the swing arm 8 of this side, the driven member 7, by disposing the oscillating arm 8 in this side, during the rotation of the bail system The generation of a moment is suppressed.

According to the fourth aspect, at the time of winding the fishing line, the balancer reciprocates along the arm opposite to the line guide, so that the weight of the line guide is offset by the weight of the balancer to rotate the rotor. The moment at the time can be reduced, and, for example, the member connected to the yarn guide portion via the bail can be balanced without adopting a configuration such as being movable along the arm portion on this side. Become.

According to the fifth aspect, at the time of winding the fishing line, the balance can be arranged at the most appropriate position, and the weight of the line guide portion and the like is offset by the operation of the balancer to reduce the moment when the rotor rotates, thereby achieving the balance. Can be taken.

[0015]

Therefore, the whole reel can be further downsized by reducing the size of the rotor without impairing the favorable aspect of downsizing the reel body, and even if the rotor is rotated at a high speed during winding of the fishing line. Thus, a spinning reel capable of smoothly winding without vibration was rationally configured.

In particular, when the reciprocating system and the rotor are independently balanced, vibration is less likely to be generated when the fishing line is wound (claim 2), and the member is opposed to the line guide portion via the bail. When the reciprocating operation is performed, the balance state appears without a special drive system (claim 3). When the balance means is constituted by a member that supports the end of the bail at a position facing the yarn guide portion, The balance state appears without using a special balancer (claim 4),
In the case where the balance means is formed at an appropriate portion of the rotor, the balance state appears by canceling out the weight of the member reciprocating with the balancer at the optimum position (claim 5).
