Description

[Detailed description of the invention]

[0001]

The present invention relates to a screw shaft which rotates in association with a spool, an engaging piece which engages in a spiral groove of the screw shaft, and is reciprocally movable in the left and right direction integrally with the engaging piece. Also, the present invention relates to an improvement in a level wind mechanism of a dual bearing reel including a thread guide member having a thread guide portion formed therein and guide members arranged in a posture parallel to a screw shaft to guide the thread guide member.

[0002]

2. Description of the Related Art Conventionally, there is a level wind mechanism L constructed as described above, as shown in FIG. 6. In this conventional example, a line guide portion 31B through which a fishing line 27 passes through the upper end of a line guide member 31 is shown. In addition, a hole 31A through which the rod-shaped guide body 25 is inserted is formed in the middle part, and an opening through which the screw shaft 21 is inserted is formed in the lower end part.

[0003]

Here, the level wind mechanism constructed as described above will be considered. In this type of level wind mechanism, as shown in FIG. 6, a hole 31A of the guide body 25 is inserted. By forming the shape slightly larger than the diameter of the guide body 25, the distance between the screw shaft 21 provided on the reel body and the guide body 25, and the distance between each of the openings formed in the guide member 31 so that the guide shaft is inserted therethrough. Even if there is some error in the distance, it is possible to assemble the reel, and to eliminate the stiffness during operation. However, in this way, the shape of the hole 31A is
5 has a good surface as described above, but on the other hand, it not only causes rattling between the hole 31A and the guide body 25, but also disturbs the posture of the thread guide member 31 during operation. There is room for improvement because abnormal noise may be generated due to vibration during winding. In addition, if the posture of the line guide member is disturbed, the winding position of the fishing line with respect to the spool is disturbed, and the contact between the fishing lines wound on the spool at the time of feeding the fishing line may increase the feeding resistance of the fishing line, In addition, abnormal noise is generated at the time of operation, which leads to discomfort during actual fishing. The purpose of the present invention is to enable easy assembly even if there is an error in the level wind mechanism, and to prevent rattling and noise during operation without impairing the conventional good surface that does not generate undulations during operation. The point is to construct a level wind mechanism that does not generate rationally.

[0004]

According to a feature of the present invention, the yarn guide member is guided by a first member holding the engaging piece and the guide body, and a yarn guide portion is formed. A first member and a second member.
A coupling mechanism that couples the member and a relative movement in a direction perpendicular to the axis of the screw shaft while allowing relative movement in the axis direction, and connecting the second member and the guide body. The function and the effect are as follows.

[0005]

When the above-mentioned feature is constituted as shown in FIGS. 1 and 2, for example, the screw 2 is attached to the first member 24 at the time of assembling the reel.
1 and the guide member 25 through the second member 26, even if there is some error in the distance between the guide member 25 and the screw shaft 21, the first member 24 and the second member 2
This error is absorbed by the relative movement of the screw shaft with the shaft 6 in a direction perpendicular to the axis of the screw shaft, and the force from the engaging piece 23 that engages with the spiral groove 21A of the screw shaft 21 during operation. Is transmitted to the second member 26 via the first member 24 and the connecting mechanism J, and the second member 26 and the first member 24 are connected to the screw shaft 21.
Are reciprocated in the lateral direction along the guide body 25 in a state in which they cannot move relative to each other in the axial center direction. Therefore,
In response to the operation of the engagement piece 23, the first member 2 is moved in the axial direction of the screw shaft.
When the member 4 moves, the second member 26 also moves integrally in the axial direction of the screw shaft, so that rattling or the like occurs in the axial direction of the screw shaft between the first member 24 and the second member 26. Hateful. Further, since the hole 26A of the second member 26 and the guide body 25 are closely fitted, there is no disturbance in the position of the thread guide 26B during operation, and no vibration is generated.
In addition, since the force is applied only in the lateral direction (in the direction along the axis X of the screw shaft 21) in the coupling mechanism J, the posture of the first member 24 is not affected. In other words, in the present invention, the yarn guide member is composed of two members that are relatively movable, and the relative movement direction is determined only in a direction perpendicular to the axis of the screw shaft, and the yarn guide member is connected so as not to be relatively movable in the axis direction of the screw shaft. The second member 2 can easily absorb the error and stably by the guide body 25.
6 guides the fishing line 2 without vibration or the like.
7 can also be wound at a predetermined position on the spool 3.

[0006]

Therefore, even if the center of the screw between the guide member and the screw shaft is installed with an error, the thread guide member can be easily assembled, and the screw shaft between the first member and the second member can be easily assembled. The relative movement in the direction perpendicular to the axis suppresses stiffness during operation, and the first member and the second member are connected to the relative movement operation in the axis direction of the screw shaft, so that rattling during operation,
The level wind mechanism, which allows smooth winding of the fishing line without generating abnormal noise, was rationally configured.
