Description

TECHNICAL FIELD The present invention relates to a fishing spinning reel capable of providing good sliding guidance of a spool shaft at a rotor mounting portion.

A spinning reel for fishing includes a pinion gear which is driven and rotated by a rotating operation of a handle connected to a drive mechanism in a reel body, and a rotor having a fishing line guide portion is fitted and fixed so as to be integrally rotatable on the outer periphery of the pinion gear. The fishing line is wound around a spool provided at the front portion of a spool shaft which is inserted inside the pinion gear so as to be able to move back and forth. The front outer circumference of the pinion gear is formed into a non-circular portion and has a male screw portion formed therein.

For this reason, the part where the non-circular part and the male screw part are formed in the front part of the pinion gear is thin, and when a large torque is applied to the thin part when tightening the nut, it deforms inward in the radial direction and the inner circumference of the pinion gear becomes a perfect circle. The contact support state with the outer circumference of the spool shaft that moves back and forth becomes unstable.

In order to suppress the inward deformation of the inner circumference of the pinion gear when the nut is tightened, a separate sliding bearing is attached to the inner circumference of the pinion gear on the rear side of the male screw portion, and the sliding bearing moves back and forth. There is known a device in which a cylindrical restricting member with a flange that restricts the pinion gear is mounted from the inner periphery on the front end side of the pinion gear and then retained by a retainer of the nut (Patent Document 1).

Japanese Patent Application Laid-Open No. 2001-258438

In the known configuration described above, a slide bearing for slidingly guiding the outer periphery of the spool shaft is arranged in the axial direction area of the inner periphery of the pinion gear, which has a thin wall thickness formed by forming a non-circular portion and a male screw portion on the outer periphery. Therefore, it is not possible to sufficiently prevent the influence of deformation of the inner circumference of the pinion gear when tightening the nut, and the spool shaft cannot be stably slidably guided on the inner circumference of the rotating pinion gear. Further, since the slide bearing is axially regulated by a cylindrical regulating member and a retainer, the number of parts increases, resulting in poor assembling workability, high cost, and a tendency to increase in size in the axial direction.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. To provide a spinning reel for fishing with a support structure that does not become brittle.

In order to achieve the above object, the present invention provides a reel body in which a rotor having a fishing line guide portion on the outer periphery of a pinion gear which is driven and rotated by a rotating operation of a handle connected to a drive mechanism in a reel body is fitted so as to be integrally rotatable. A spinning reel for fishing in which a fishing line is wound around a spool provided on a front portion of a spool shaft that is engaged and fixed and inserted movably back and forth inside a pinion gear, wherein the front portion of the pinion gear rotates around the rotor. It comprises a fixing area having a male screw part formed on the outer periphery of the non-circular part to be stop-fitted and having a male screw part for screwing a tightening nut, and a support area in which a support member for supporting the outer periphery of the spool shaft is arranged. a clearance fitting portion is formed radially inward of the pinion gear beyond the fixing region where the nut is screwed from the front end of the pinion gear, and the support member is adapted to move the spool shaft back and forth; It is characterized in that it is regulated not to follow.

In the fishing spinning reel of the above configuration, when the rotor is fixed by tightening the nut with the male screw portion formed on the outer circumference of the front portion of the pinion gear, the non-circular portion where the male screw portion is formed is Although it tries to be deformed by receiving pressure inward in the radial direction, this part has a clearance fitting portion beyond the fixed area where the nut is screwed and tightened, so it is not against the reciprocating spool shaft. Therefore, the inner circumference of the pinion gear or the inner circumference of the support member does not affect the spool shaft, and the spool shaft can be slidably guided in a stable state, and the manufacturing cost can be efficiently reduced. .

Further, in order to achieve the above object, the present invention provides a rotor having a fishing line guide portion on the outer periphery of a pinion gear which is driven and rotated by a rotating operation of a handle connected to a drive mechanism in a reel body so as to rotate integrally with the rotor. A spinning reel for fishing in which a fishing line is wound around a spool provided at the front of a spool shaft which is fixed by stop fitting and inserted movably back and forth inside a pinion gear, wherein the front of the pinion gear is connected to the rotor. A fixing region having a male threaded portion for screwing a tightening nut formed on the outer periphery of a non-circular portion that is fitted to prevent rotation of the spool shaft, and a support region that supports the outer periphery of the spool shaft, and the nut A reinforcing cylindrical body formed of a material having a higher strength than the pinion gear is fitted and fixed to the inner circumference of the pinion gear in the fixing region where the pinion gear is screwed.

In such a configuration as well, when the rotor is fixed by tightening the nut with the male threaded portion formed on the outer periphery of the front portion of the pinion gear, the non-circular portion where the male threaded portion is formed extends radially inward. Although it tries to deform under pressure, since a reinforcing cylinder with higher strength than the pinion gear is fitted and fixed to this part, it will not affect the reciprocating spool shaft, and the spool shaft will be in a stable state. can be smoothly slidably guided, and the manufacturing cost can be efficiently reduced.

An embodiment of a spinning reel for fishing according to the present invention will be specifically described below with reference to the accompanying drawings.
First, the configuration of a spinning reel for fishing will be described with reference to FIGS. 1 and 2. FIG.

A reel body 1A of a fishing spinning reel (hereinafter referred to as a reel) 1 according to the present embodiment is integrally formed with a reel leg 2 to be attached to a fishing rod. A rotor 3 and a spool 4 supported so as to move back and forth in synchronism with the rotary motion of the rotor 3 are arranged.

Said rotor 3 comprises a pair of arms 3a (only one is shown in FIG. 1) rotating around a spool 4, each arm 3a having a front end of a bail 3b. A bail support member 3c to which a base end is attached is rotatably supported between a line winding position and a line releasing position. One base end of the bail 3b is attached to a fishing line guide portion 3d integrally provided with the bail support member 3c.

A handle shaft 5 is rotatably supported in the reel body 1, and a handle 6 is attached to the protruding end thereof. A drive mechanism 10 is engaged with the handle shaft 5. The drive mechanism 10 includes a drive gear 7 attached to the handle shaft 5 so as to be rotatable integrally with the drive gear 7 and a tooth portion 8a that meshes with the drive gear 7. and a pinion gear 8 extending in a direction orthogonal to the handle shaft 5 and having an axially extending hollow portion formed therein.

The pinion gear 8 is rotatably supported in the reel body 1 by a pair of bearings 9a and 9b fitted and supported by the support portion of the reel body 1A at the front side and the rear side of the tooth portion 8a. . Further, the pinion gear 8 extends toward the spool 4 side, and the rotor 3 is fitted to the tip of the pinion gear 8 so as to rotate integrally with the rotor 3 through a tightening nut 12 . ing.

A known one-way clutch 15 constituting a reverse rotation prevention mechanism is mounted on the pinion gear 8 on the front side of the bearing 9b arranged on the front side of the tooth portion 8a. As is well known, the one-way clutch 15 holds an inner ring 15a, an outer ring 15b, a rolling member 15c held between the inner ring 15a and the outer ring 15b, and a rolling member 15c. The retainer 15d engages with the retainer 15d, and by rotating a switching operation lever 16 provided outside the reel body 1A, the one-way clutch 15 is operated, and the handle 6 (rotor 3 ) in the fishing line payout direction (reverse rotation).

A hollow portion formed inside the pinion gear 8 (a hollow portion formed by the inner peripheral surface 8A of the pinion gear 8) extends in a direction orthogonal to the handle shaft 5, and a spool 4 is mounted on the tip side. A spool shaft 20 is inserted movably in the axial direction. The rear end of the spool shaft 20 is engaged with a known spool reciprocating device 40 for reciprocating the spool 4 (spool shaft 20) back and forth.

In the reel having such a structure, when the handle 6 is operated to wind, the rotor 3 is rotationally driven via the drive mechanism 10 and the spool 4 is reciprocated back and forth via the spool reciprocating device 40. Therefore, the fishing line is evenly wound around the winding drum portion 4a of the spool 4 via the fishing line guide portion 3d.

Next, a support structure for supporting the spool shaft 20 on the inner circumference of the pinion gear 8 at the portion where the rotor 3 is mounted will be described with reference to FIGS. 1 to 3. FIG.

The front portion of the pinion gear 8 is provided with a non-circular portion having an oval cross section or the like so as to prevent rotation of the rotor 3, and the tightening nut is mounted on the outer circumference of the non-circular portion. A male screw portion 8b for screwing 12 is formed. That is, a through-hole 3f is formed in the central portion (central base portion 3A) of the rotor 3 and engages the non-circular portion of the pinion gear 8 to prevent rotation. Rotor 3 is fixed with respect to pinion gear 8 by tightening 12 .

In the present invention, the region where the male screw portion 8b is formed (region in the axial direction shown in FIG. 3) is defined as a fixing region L. As shown in FIG. A through hole 3f formed in the central base portion 3A of the rotor 3 is fitted to the tip side of the pinion gear 8, and the rotor 3 is positioned in a state in which the rotor 3 is in contact with the inner ring 15a of the one-way clutch 15. In this state, the nut Rotor 3 is fixed by tightening 12 . At this time, a radially inward stress acts on the non-circular portion of the fixing region L, which has become thin due to the tightening of the nut 12 .

A spool shaft 20 inserted through a cavity formed inside the pinion gear 8 is supported so as not to contact the inner peripheral surface 8A of the pinion gear 8 as much as possible in order to reduce sliding resistance. Specifically, the spool shaft 20 is supported in the intermediate portion of the pinion gear 8 so as to be in a non-contact state (a state in which a gap G is created), and the tip end side of the spool shaft 20 is positioned at the tip end side of the pinion gear 8. It is in a state of being supported by the press-fitted support member 30 (a manner of supporting the rear end side of the spool shaft will be described later).
In the present invention, a support region R is defined as a region where the tip end side of the spool shaft 20 is supported by the support member 30 (region in the axial direction shown in FIG. 3).

A clearance fitting portion S is formed radially inside the pinion gear 8 beyond the fixed region L where the nut 12 is screwed from the front end of the pinion gear 8 . In this embodiment, the support member 30 press-fitted to the front end side of the pinion gear 8 is configured such that the entire inner peripheral surface thereof contacts the outer peripheral surface of the spool shaft 20, and the small diameter portion 30a is formed on the tip side. This portion is press-fitted into an annular recess 8c formed on the tip side of the pinion gear 8. As shown in FIG. That is, on the tip side of the pinion gear 8, a small-diameter annular recess 8c is formed axially inward, and a larger-diameter annular recess 8d is continuously formed axially outward. The small diameter portion 30a of the support member 30 is press-fitted and fixed in the annular recess 8c, and the annular recess 8d The clearance fitting portion S is formed between the inner peripheral surface of the .

In this case, by forming the axial length of the annular recess 8d to be longer than the fixing region L in which the male screw portion 8b is formed, when the nut 12 is tightened, as shown in FIG. A clearance fitting portion S is formed up to a portion W that is longer inward in the axial direction than the region to be tightened (the fixed region L and the portion beyond the fixed region L form a clearance region), and the nut 12 of the pinion gear 8 is tightened. It allows radially inward deformation that occurs during tightening.
That is, in this embodiment, the gap fitting portion S is formed between the inner peripheral surface of the front portion of the pinion gear 8 and the outer peripheral surface of the support member 30 press-fitted into the pinion gear.

Further, since the spool shaft 20 is driven to reciprocate back and forth within the hollow portion of the pinion gear 8, the support member 30 is regulated so as not to follow the back and forth movement of the spool shaft 20. As shown in FIG. In this embodiment, a flange (flange) 30c is formed at the open end of the support member 30, and when the small-diameter portion 30a of the support member 30 is press-fitted into the annular recess 8c of the pinion gear 8, the flange 30c is attached to the pinion. It abuts against the tip edge of the gear 8 .

The support member 30 is regulated so as not to follow the spool shaft 20 even if it moves back and forth by the press-fit fixing of the small-diameter portion 30a into the annular recess 8c of the pinion gear 8 and the flange 30c.

According to the above-described configuration, when the rotor 3 is fixed by tightening the nut 12 at the portion of the male screw portion 8b formed on the outer periphery of the front portion of the pinion gear 8, the non-circular portion where the male screw portion 8b is formed ( The thin-walled portion) tries to deform (inwardly deform) by receiving pressure inward in the radial direction. extends to the portion W beyond the fixed region L, sufficiently preventing the influence of the inward deformation, and the inner circumference of the pinion gear 8 or the inner circumference of the support member 30 with respect to the reciprocating spool shaft 20. The spool shaft 20 is no longer affected. That is, the spool shaft 20 can be smoothly slidably guided in a stable state. Moreover, since there is no restriction member for restricting movement in the axial direction as in the prior art, the manufacturing cost can be efficiently reduced by reducing the number of parts without increasing the size.

The support member 30 is formed with a small diameter portion 30a having a stepped portion 30b. It may be configured such that the pinion gear 8 is press-fitted into the annular recess 8c of the pinion gear 8, and a clearance fitting portion S is formed between the pinion gear 8 and the inner peripheral surface of the annular recess 8d (see FIG. 4).

In the above-described configuration, the support member 30 is restricted in the axial direction by press-fitting the flange (collar portion) 30c formed at the open end of the support member 30 and the small diameter portion 30a. The support member (support structure at the rotor portion of the spool shaft) can be configured as shown in FIG. 4 (first modification).
The support member 31 of this modified example is simply formed into a cylindrical shape and press-fitted into the pinion gear 8 without forming a flange at the end.

The axial length of the support member 31 is formed so as to be substantially the same as the tip of the pinion gear 8 when it is pressed into the pinion gear 8 and pressed against the bottom of the annular recess 8c. , a well-known anti-rotation plate 12A for preventing rotation of the nut 12 is fixed to the front surface of the rotor 3 by screws 12B, and the bent bottom surface 12C is brought into contact with the opening end surface of the support member 31, thereby It restricts movement in the axial direction.

With such a configuration, there is no need to process the support member 31 to form a flange, so the manufacturing cost can be efficiently reduced.

FIG. 5 is a diagram showing a second modification of the support member (support structure at the rotor portion of the spool shaft) that supports the spool shaft.
The support member 31 shown in FIG. 4 is configured in a straight shape, and its axial movement is restricted by the anti-rotation plate 12A. However, as shown in FIG. The restricting wall portion 12D may be integrally formed, and the flange portion 12D' bent radially inward at the end thereof may be used to prevent slippage.
With such a configuration, the number of parts can be reduced. Further, in such a configuration, the flange portion 12D' may be in contact with the flange 30c of the support member 30, or may be separated as shown in the figure. Further, the support member 30 does not have to be provided with the flange 30c, and like the configuration of FIG.

FIG. 6(a) is a view showing a third modification of the support member (support structure at the rotor portion of the spool shaft) that supports the spool shaft.
In this modification, the gap fitting portion S is formed between the inner peripheral surface of the pinion gear 8 on the front side of the support member 33 (the inner peripheral surface of the annular recess 8d) and the outer peripheral surface of the spool shaft 12. there is That is, the gap fitting portion S is formed between the spool shaft 12 and the pinion gear 8 radially inward of the portion W beyond the fixing region L where the nut 12 is screwed from the front end of the pinion gear 8 . . The support member 33 of this embodiment is formed in a cylindrical shape, and is configured to be press-fitted into the annular recess 8c through a large-diameter annular recess 8d formed on the tip side of the pinion gear 8. .

In such a configuration, the axial length of the annular recess 8d is formed longer than the fixing region L in which the male threaded portion 8b is formed, so that when the nut 12 is tightened, the male threaded portion is formed. Since the influence of radially inward deformation of the non-circular portion can be prevented, even in this modified example, the spool shaft can be slidably guided in a stable state, and the manufacturing cost can be efficiently reduced. becomes.

FIG. 6(b) is a diagram showing a fourth modification, in which a single annular recess 8c is formed as it is without forming the large-diameter annular recess 8d shown in FIG. 6(a). , the support member 33 is inserted inward from the tip opening of the pinion gear 8 and is positioned by contacting the bottom. That is, while preventing the support portion from being affected by the radially inward deformation of the pinion gear 8 when the nut 12 is tightened, the slight radially inward deformation of the support member 33 is utilized. It is configured to restrict axial movement.

FIG. 7 is a view showing a fifth modification of the support member (support structure at the rotor portion of the spool shaft) that supports the spool shaft.
In this modification, an annular recessed portion 33a is formed in the intermediate portion of the support member 33 so that when the support member 33 is press-fitted and fixed, it is partially out of contact with the inner peripheral surface of the pinion gear 8. are doing.

With such a configuration, the weight of the supporting member can be reduced. Moreover, it is possible to reduce the rotational resistance of the pinion gear 8 . Such an annular recess 33 a may be formed on the side facing the spool shaft 20 . By forming it on the spool shaft side, it is possible to reduce sliding resistance when the spool shaft 20 moves back and forth.

Further, although the materials for forming the support members 30, 31, and 33 are not limited, weight reduction can be achieved by forming them from synthetic resin.

8A and 8B are diagrams showing a second embodiment of the present invention. FIG. 8A is a diagram showing a support structure for supporting the spool shaft on the inner periphery of the pinion gear at the portion where the rotor is mounted; ) is an enlarged view of the main part of FIG.
In this embodiment, a reinforcing cylindrical body 50 made of a material having a higher strength than the pinion gear 8 is fitted and fixed to the inner periphery of the pinion gear 8 in the fixing region L where the nut 12 for fixing the rotor 3 is screwed. is characterized by

Normally, the pinion gear 8 is made of a metal material such as brass, and in such a case, the reinforcing cylinder 50 can be made of a higher strength material such as SUS. .
With such a configuration, as in the above-described embodiment, when the nut 12 is tightened at the portion of the male thread portion 8b to fix the rotor 3, the non-circular portion where the male thread portion 8b is formed is radially inward. Although it tries to be deformed under pressure, since the reinforcing cylindrical body 50 having higher strength than the pinion gear 8 is fitted and fixed to this portion, the reciprocating spool shaft 20 is not affected, and the spool shaft is supported. Sliding guidance can be performed smoothly in a stable state, and manufacturing costs can be efficiently reduced.

The reinforcing cylindrical body 50 may be simply press-fitted from the tip opening of the pinion gear 8, or may be adhered. Moreover, it is preferable to form a flange portion 50a at the tip so that the press-fitted state is stabilized.
Further, as a method for restricting the axial direction of the reinforcing cylinder 50, the bottom surface 12C of the detent 12A (illustrated by the dashed line) of the nut 12 as shown in FIG. .

The reinforcing cylinder 50 may be formed in the portion where the threaded portion 8b is formed (within the fixing region L), but it may extend beyond the fixing region L toward the rear of the reel main body. It is preferably extended. That is, by forming the length longer than the fixing region L, it is possible to reliably suppress radial deformation of the non-circular portion when the nut 12 is tightened.

The reinforcing cylinder 50 may have its inner surface in contact with the spool shaft 20 to serve as a support area for the spool shaft 20. However, as in the above-described embodiment, the support member 37 is positioned closer to the reel body than the fixing area L. It may be press-fitted, the reinforcing cylindrical body 50 may be made non-contact, and the support region R may be formed by the support member 37 portion. In other words, the support member 37 may be arranged side by side with the reinforcing cylinder 50 at a position extending rearward on the reel body side from the fixed region to constitute the support region.

According to such a configuration, the reinforcing cylinder 50 is spaced from the spool shaft 20, and even if deformation occurs in the fixing region L, it is possible to reliably prevent the spool shaft 20 from being affected and to contact the spool shaft 20. Therefore, the spool shaft 20 can be stably slidably guided. Further, by making the support member 37 made of resin, it is possible to efficiently reduce the weight.

In the above-described embodiment, the spool shaft 20 inserted through the pinion gear 8 is located inside the pinion gear 8 other than the support region R in order to reduce sliding resistance, as disclosed in the above-mentioned Patent Document 1. is configured to be non-contact. In this case, the rear end side of the spool shaft 20 may be formed as a rear support region by reducing the diameter of the rear end region of the inner circumference of the pinion gear 8 as disclosed in Patent Document 1, or as shown in FIG. In addition, the region of the pinion gear 8 may be kept in a non-contact state, and may be supported in contact with the reel body 1A and the collar 1B disposed on the reel body 1A (the collar 1B shown in FIG. It also has a rotatable support function).
The present invention relates to an improvement in the support area that supports the outer periphery of the spool shaft 20 on the inner peripheral side of the front portion of the pinion gear 8. Regarding the support structure on the rear side of the spool shaft 20 that is inserted into the pinion gear 8, , is not particularly limited.
Further, the bearing support configuration (support position of the bearing, the number of bearings, etc.) of the pinion gear 8 rotatably supported by the reel body 1A is not limited.

In this manner, the spool shaft 20 is supported in the front and rear support regions of the pinion gear 8, and the gap G is formed between the support regions and the inner peripheral surface 8A of the pinion gear 8 in the intermediate portion thereof. Although it is possible to improve the slidability of the movement, in such a configuration, measures to more effectively prevent scratches and wear on the surface of the spool shaft 20 (if the surface of the spool shaft is scratched, , which causes problems such as abnormal noise, rough rotation, and slow rotation), the surface of the spool shaft 20 is coated with grease or oil (lubricating oil).

However, if oil adheres to the surface of the spool shaft 20, the oil may dissipate due to long-term use. It is known to form spiral grooves on the surface or to form annular grooves at regular intervals in the axial direction to form oil reservoirs. Since the contact area between the inner peripheral surface of the pinion gear and the spool shaft increases, the sliding resistance cannot be sufficiently reduced.

Therefore, between the front and rear support regions of the spool shaft 20 that is inserted into the inner peripheral side of the pinion gear 8 that rotates during the winding operation and that moves back and forth, the axial and peripheral surfaces of the pinion gear 8 are supported. A large number of recesses (fine holes) 8p as shown in FIG. 9 are formed on the surface without making contact in all directions (while maintaining the gap G).
Such a large number of recesses 8p can be formed by, for example, Superoll, shot blasting, etc., and it is possible to reduce the sliding resistance while maintaining the applied oil or the like. By forming the depth D deeper than the gap G, it becomes possible to reduce the sliding resistance while maintaining the applied oil reliably. Further, the shape and formation position of the large number of recesses are not particularly limited, but may be circular holes as shown in FIG. 8q, and a slot 8r extending in the circumferential direction as shown in FIG. 10(b). The edges of the recesses 8p, the elongated holes 8q, the elongated holes 8r, etc. are subjected to polishing such as deburring, if necessary.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified in various ways.
Regarding the manner of supporting the spool shaft 20 in the above-described embodiment, the thinned non-circular portion at the mounting portion where the rotor 3 is fixed is configured so that the tightening of the nut 12 does not affect the spool shaft 20. The method of forming the gap fitting portion S, the axial length of the gap fitting portion S, the structure of the reinforcing cylinder 50, and the like can be modified as appropriate. Also, the configuration of the reel body 1A, the drive mechanism 10, the spool reciprocating mechanism 40, etc., other than the support section for the spool shaft, can be modified in various ways.
