2. Description of the Related Art In general, a spinning reel has a reel body, a rotor rotatably supported by the reel body, and a spool around which a fishing line is wound. The rotor has a pair of arms, and a bale is provided between the two arms so as to be openable and closable between a line winding position and a line releasing position. Further, a line roller for guiding the fishing line wound at the time of winding the line to the outer periphery of the spool is provided at one end of the arm portion.

[0003] In such a spinning reel, an oscillating mechanism is provided to uniformly wind the fishing line guided by the bail and the line roller around the spool in the front-rear direction. The oscillating mechanism has a screw shaft arranged in parallel with the spool shaft to which the spool is fixed, a gear mechanism for rotating the screw shaft, and a slider that engages with the screw shaft. A spiral groove is formed on the outer periphery of the screw shaft, and a part of the slider is engaged with the groove. The slider is fastened to the rear end of the spool shaft by a screw. When the slider reciprocates along the screw shaft, the spool shaft and the spool also reciprocate. Particularly in a large spinning reel, the force acting on the spool shaft is large, and with a single screw, the screw is likely to loosen when the spool shaft is twisted by drag. Therefore, the slider and the spool shaft are fastened by two screws arranged side by side in the axial direction of the spool shaft. In order to avoid interference with the tooth tip of the face gear provided on the handle shaft when the slider moves forward,
Usually, small screws are used.

[0004]

In the conventional oscillating mechanism in which the slider is fastened to the spool shaft by two small screws, the diameter of the head of the small screws is large. , The axial length of the slider becomes longer. For this reason, it is difficult to reduce the size of the reel body.

An object of the present invention is to reduce the length of the slider in the spool axis direction as much as possible when the slider and the spool shaft are fastened with two screws.

[0006]

Placed
This is a screw for fastening the slider to the spool shaft.

In this slider mounting structure, the first screw and the second screw are arranged adjacent to each other such that their heads overlap. For this reason, the distance between the first screw and the second screw can be reduced, and even if the slider and the spool shaft are fastened with two screws, the length of the slider in the spool axis direction is made as short as possible. can do. According to a second aspect of the present invention, there is provided a spinning reel slider mounting structure according to the first aspect, wherein the first screw is a small screw. In this case,
Since the head of the further small screw can be positioned flush with or outside the outer surface of the slider, if a screw other than the further small screw is used as the second screw, the head of one screw can be easily overlapped. it can. Further, since the head of the first screw of the small screw is pressed by the head of the second screw, the screw is less likely to be loosened.

According to a third aspect of the present invention, there is provided a spinning reel slider mounting structure according to the first or second aspect.
The screw is a truss machine screw. In this case, the heads of the two screws can be easily overlapped by using a further small screw for the first screw or disposing the head of the first screw inside the outer surface of the slider. According to a fourth aspect of the present invention, in the slider mounting structure for a spinning reel according to any one of the first to third aspects, the first screw and the second screw are respectively inserted from opposing outer surfaces of the slider. In this case, the heads of the two screws can be overlapped regardless of the type of screw used. Further, if a small screw is used for the two screws, the protrusion of the head from the outer surface of the slider is suppressed, and it is difficult to interfere with the face gear and the like.

BEST MODE FOR CARRYING OUT THE INVENTION

[Overall Structure and Structure of Reel Body] A spinning reel according to an embodiment of the present invention shown in FIGS.
, A rotor 3 rotatably supported at the front of the reel body 2, and a spool 4 disposed at the front of the rotor 3 to wind up fishing line.

The reel body 2 has a body 2a,
At its upper part, an attachment part 2b for attaching the spinning reel to the fishing rod is formed. A rotor drive mechanism 5 for rotating the rotor 3 is provided inside the body 2a.
And an oscillating mechanism 6 for moving the spool 4 in the front-rear direction along the rotation axis X to uniformly wind the fishing line on the spool 4.

The rotor drive mechanism 5 has a face gear 11 that rotates together with a shaft 10 to which the handle 1 is fixed, and a pinion gear 12 that meshes with the face gear 11. The pinion gear 12 is formed in a cylindrical shape, and a front portion 12 a of the pinion gear 12
Extends to the side. And the screw part is formed in the front-end | tip. The pinion gear 12 has an axial middle portion and a rear end portion rotatably supported by the reel body 2 via bearings 13 and 14, respectively.

The oscillating mechanism 6 is a mechanism for moving the spool shaft 20 fixed to the center of the spool 4 in the front-rear direction to move the spool 4 in the same direction. The oscillating mechanism 6 has a screw shaft 21 disposed below the spool shaft 20, a slider 22 that moves in the front-rear direction along the screw shaft 21, and an intermediate gear 23 fixed to a tip of the screw shaft 21. doing. The screw shaft 21 is arranged in parallel with the spool shaft 20, and is rotatably supported by the body 2a. A spiral groove 21a is formed on the outer periphery of the screw shaft 21.

The slider 22 is fixed to the rear end of the spool shaft 20. The intermediate gear 23 is a pinion gear 12.
Are engaged. Here, the number of teeth of each of the pinion gear 12 and the intermediate gear 23 is set such that the rotation speed ratio of the pinion gear 12 to the screw shaft 21 is 1.5 or more, and preferably 1.8 to 2.5. I have. If the rotational speed ratio is less than 1.5, it is not possible to improve the efficiency of winding the fishing line. When the rotation speed ratio is 1.8 or more, the efficiency is remarkably improved.
3 becomes too large, and it is difficult to reduce the size of the reel body 2.

[Structure of Slider] The slider 22 is shown in FIG.
7, a slider main body 25 and an engaging member 26 housed in the slider main body 25 are provided. The slider body 25 is fastened to the spool shaft 20 so as not to be movable in the axial direction by two screws 27a and 27b arranged side by side in the axial direction of the spool shaft. Book guide shafts 29a, 2
9b is slidably mounted. A cutout 20a is formed in a portion of the spool shaft 20 that fits with the slider body 25, and a part of the outer periphery is flat. And
The corresponding holes in the slider body 25 are also not perfectly circular,
It has a flat portion corresponding to the notch 20a. Due to such fitting, the relative rotation of the slider body 25 with respect to the spool shaft 20 is prohibited. A screw hole 20b for fastening the slider is formed in the notch 20a at an interval in the axial direction.
20c are formed.

Two through holes 25b and 25c are formed in the slider body 25 along the direction intersecting with the spool shaft 20 so as to face the screw holes 20b and 20c.
Two screws 27a are inserted into these two through holes 25b and 25c.
27b are respectively inserted and screwed into the screw holes 20b and 20c. The screw 27a is a flat-head screw having a large-diameter flat head 28a and a small-diameter screw portion 28b extending from the head 28a. The screw 27b has a large-diameter head 28c and a small-diameter head extending from the head 28c. This is a truss machine screw having a screw portion 28d. At the opening of the through hole 25b on the lower outer surface of the slider body 25 in FIG.
5d is formed. Screw 2 into this head storage hole 25d
The head 28a of the slider body 7a is housed, and the head 28a is arranged substantially flush with the outer surface of the slider main body 25 or inside the outer surface when fastening.

The two screws 27a and 27b have their heads 2
8a and 28c are superimposed, and are arranged so that the head 28c presses the head 28a accommodated in the head accommodation hole 25d, and is arranged closer than before. For this reason,
Even if the slider 22 and the spool shaft 20 are fastened with the two screws 27a and 27b, the length of the slider 22 in the spool axis direction can be reduced as much as possible, and the length of the reel body 2 in the spool axis direction can be reduced. It is possible to reduce the size of the reel body 2 while suppressing the size. The head 28a of the screw 27a is
Since the screw 27b is pressed by the head 28c, the two screws 27a and 27b are less likely to be loosened.

Further, since the slider body 25 is guided by the two guide shafts 29a and 29b, inclination during sliding is prevented. Therefore, it is not necessary to form the slider main body 25 so as to cover the entire circumference of the screw shaft unlike the conventional slider main body. For this reason, the slider body 25 of the present embodiment
Is shaped so as to face only one side surface of the screw shaft 21 and has less protrusion on the other side surface.
Therefore, the length of the reel body in the direction intersecting with the spool shaft 20 can be suppressed, and the reel body 2 can be made smaller.

A horizontal hole 25a is formed in the slider body 25 so as to be orthogonal to the screw shaft 21, and an engaging member 26 is slidably inserted into the hole 25a.
At the tip of the engaging member 26, an engaging portion 26a that meshes with the groove 21a of the screw shaft 21 is formed. The lid member 24 is fixed to one end of the hole 25a of the slider body 25. [Structure of Rotor] As shown in FIG. 1, the rotor 3 has a cylindrical portion 30, and a first arm portion 31 and a second arm portion 32 provided on the sides of the cylindrical portion 30 so as to face each other. ing. The cylindrical portion 30 and the arms 31 and 32 are integrally formed.

A front wall 33 is formed at the front of the cylindrical portion 30, and a boss 33a is formed at the center of the front wall 33. A through hole is formed at the center of the boss 33a, and the front portion 12a of the pinion gear 12 and the spool shaft 20 pass through the through hole. A nut 34 is arranged on the front side of the front wall 33, and the nut 34 is screwed into a tip thread portion of the pinion gear 12. A bearing 3 for rotatably supporting the spool shaft 20 is provided on an inner peripheral portion of the nut 34.
5 are arranged.

A first bail support member 40 is swingably mounted on the inner peripheral side of the distal end of the first arm portion 31. A line roller 41 for guiding the fishing line to the spool 4 is attached to the tip of the first bail support member 40. A second bail support member 42 is swingably mounted on the inner peripheral side of the tip of the second arm 32. The second bail support member 42 is made of, for example, a material having a higher specific gravity than other portions, and functions as a balancer for eliminating imbalance during rotation caused by the first bale support member 40 and the line roller 41. Is also possible. A bale 43 is provided between the line roller 41 at the tip of the first bail support member 40 and the second bale support member 42. By attaching the first bail support member 40 to the inner peripheral side of the first arm portion 31 in this manner, the radius of rotation of the first bail support member 40 is reduced, and it is difficult to hit the hand holding the fishing rod. Therefore, the spool and the fishing rod can be brought close to each other, and the overall size can be reduced. Further, for the same reason, the radius of rotation is reduced, and it is easy to suppress imbalance during rotation.

Further, covers 44 and 45 are attached to the outer peripheral sides of the arms 31 and 32, respectively. The surfaces of the covers 44 and 45 are smoothly continuous in the front-rear direction and the circumferential direction, so that the catch of the fishing line can be prevented. Here, both bail support members 4
Numerals 0 and 42 are swingable around one swing axis M.
The point at which the pivot axis M intersects with the first bail support member mounting surface of the first arm unit 31 is defined as the pivot center C1, and the pivot axis M and the second bail support member mounting surface of the second arm unit 32 are set. When the point at which と intersects is the swing center C2, the swing center C2 is located on the front side of the swing center C1. That is, the swing axis M is inclined with respect to the rotation axis X. The bail support members 40 and 42 are arranged such that their swing surfaces are orthogonal to the swing axis M.

[Structure of Spool] The spool 4 is disposed between the first arm portion 31 and the second arm portion 32 of the rotor 3, and is mounted on the tip of the spool shaft 20 via a drag mechanism 70. I have. The spool 4 has a bobbin trunk 4a around which the outer periphery of the 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. Flange plate 4
"c" is formed of a stainless steel plate material, and is attached to the bobbin trunk 4a by screws. At this time, the flange plate 4c is slightly curved, and is attached so that no gap is formed between the front end of the bobbin trunk 4a and the flange plate 4c by utilizing the spring property of the curvature. Therefore, the fishing line does not enter between them.

The drag mechanism 70 includes a pressing member 71 pressed against the inner front end face of the spool 4, an adjusting knob 72 for adjusting the drag force, and a pressing spring disposed between the pressing member 71 and the adjusting knob 72. 73, 74
And a plurality of clutch plates 75 arranged between the pressing member 71 and the spool 4. In such a configuration, by adjusting the amount of tightening of the adjustment knob 72, the pressing force of the pressing member 71 against the spool 4 can be adjusted, and the drag force can be adjusted.

[Reel Operation and Operation] At the time of casting, the bail 43 is moved down to the line releasing position. As a result, the first and second bail support members 40 and 42 move
Around the same direction. At this time, the first bail support member 40 is disposed on the inner peripheral side of the first arm portion 31,
Further, since the swing shaft M is inclined with respect to the rotation axis X as shown in FIG. 1, the first bail support member 40 and the line roller 41 at the tip thereof are further on the inner circumferential side than the position in the line winding posture. Go to For this reason, the fishing line fed during casting is less likely to become entangled with the first bail support member 40 and the line roller 41. Further, the swing axis M is the rotation axis X
However, the bail support members 40 and 42 rotate about one swing axis M, and their respective rotation surfaces are perpendicular to the swing axis M. For this reason, the veil 43
Can be operated smoothly without prying.

At the time of winding the fishing line, the bail 43 is moved down to the line winding position. When the handle 1 is rotated in this state, the torque is transmitted to the pinion gear 12 via the handle shaft and the face gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the pinion gear front portion 12a. On the other hand, the pinion gear 12
The screw shaft 21 is rotated by the intermediate gear 23 that meshes with the slider 21, and the slider 22 that meshes with the groove 21a of the screw shaft 21 is guided by the guide shafts 29a and 29b to move in the front-rear direction. Therefore, the spool shaft 20 and the spool 4 reciprocate in the front-rear direction along the rotation axis X, and the fishing line guided to the spool 4 by the bail 43 and the line roller 41 is uniformly distributed on the outer periphery of the spool 4 in the front-rear direction. It is wound up. Here, since the rotation speed ratio of the pinion gear 12 to the screw shaft 21 is set to 1.5 or more, the moving speed of the spool 4 can be made lower than that of the conventional device, and the efficiency of winding the fishing line can be improved. Further, a large amount of fishing line can be wound.

The slider 22 has two guide shafts 29.
Since they reciprocate while being guided by a and 29b, they reciprocate smoothly without rotating or tilting. Therefore, the slider body 25 does not need to cover the entire circumference of the screw shaft 21, and the space on the opposite side of the engagement member 26 can be reduced. Therefore, the rear portion of the reel body 2 can be less protruded in the lateral direction. Moreover, when the slider 22 is
Even if the two screws 27a and 27b are used for fastening,
Since the heads 28a and 28c of the a and 27b are superimposed,
The distance between the two screws 27a and 27b is smaller than in the prior art, and the length of the slider body 25 in the spool axis direction is shorter. For this reason, the rear portion of the reel body 2 can be reduced in axial projection, and the reel body 2 can be made small even with a large spinning reel.

[About imbalance during rotor rotation]
When the rotor 3 rotates, unbalance during rotation is likely to occur due to members such as the bale 43. For this reason, in the present embodiment, in order to eliminate the unbalance due to the bail support members 40 and 42, the line roller 41 and the bail 43, the rear ends of the arms 31 and 32 are shifted toward the bale side in the line winding posture. And each bail support member 40, 4
2 is arranged so that its swinging axis is deviated from the rotation axis X to the bail side in the line releasing posture. Further, the imbalance caused by the line roller 41 is suppressed by disposing the second bail support member 42 on the front side of the first bail support member 40. Further, by configuring the second bail support member with a heavy material having a higher specific gravity than other members, it is possible to function as a balancer.

[Other Embodiments] (a) In the above embodiment, the slider 22 is fastened to the spool shaft 20 with a further small screw and a truss small screw, but the form of the screw is not limited to these. As shown in FIG. 8, a cylindrical head storage hole 25d is formed on the outer surface of the slider body 25, and a head 28a of a screw 27a made of, for example, a hexagon socket head cap screw is stored therein. The heads 28a and 28c of the 27a and 27b may be overlapped. Alternatively, two head storage holes formed in a stepped manner so that the heads overlap each other may be provided, and two screws may be mounted therein.

(B) In the above embodiment, the slider body 2
5, two screws 27a and 27b were mounted from the same outer surface, but as shown in FIG.
7a and 27b may be attached. In this case, the head 2 of the two screws 27a and 27b can be used without providing the head storage hole.
8a and 28c can be arranged in an overlapping manner. In this embodiment, for example, a flat head screw having a flat head portion 28a is used as the screw 27a so as to avoid interference with the tooth tip of the face gear 11. Here, if a head storage hole is formed and this head 28a is stored so as to be flush with the outer surface, interference can be avoided more reliably.

[0032]

As described above, according to the present invention, since the first screw and the second screw are arranged adjacent to each other so that their heads overlap each other, the first screw and the second screw are arranged. Can be reduced, and the length of the slider in the spool axis direction can be reduced as much as possible even if the slider and the spool shaft are fastened with two screws.
