Description

Spinning reel for fishing

The present invention relates to a spinning reel for fishing.

Conventionally, there is a known spinning reel for fishing that has a reverse rotation prevention device on a drive shaft. The reverse rotation prevention device has a function of allowing the drive shaft and the rotor mounted on the drive shaft to rotate in the line winding direction, while preventing rotation in the reverse direction opposite to the direction (hereinafter simply referred to as "reverse"). The spinning reel for fishing is configured such that a drive gear shaft is mechanically connected via a drive gear engaged with a pinion of the drive shaft so that the reverse rotation of a handle mounted on the drive gear shaft is prevented by the reverse rotation prevention device.

On the other hand, as a spinning reel for fishing, there is a known spinning reel for fishing in which a reverse rotation prevention device is arranged on the drive gear shaft (for example, refer to Patent Document 1). The spinning reel for fishing in Patent Document 1 enables the reversal of the rotor by lever operation, and in order to achieve this, the reverse rotation prevention device is excluded from the drive shaft. In the spinning reel for fishing in Patent Document 1, the reverse rotation prevention device arranged on the drive gear shaft restricts the reverse driving force from being transmitted to the handle when the rotor is reversed by lever operation, thereby preventing the handle from reversing together with the rotor.

[Patent Document 1] Japan Patent No. 6518520

In a conventional fishing reel, the backlash caused by the engagement between the small gear of the drive shaft and the drive gear often causes the drive gear shaft and the handle to loosen in the reverse direction. In particular, when the fishing method is to wind the handle little by little, the handle is stopped little by little each time, which often causes looseness and impairs the operating feel of the handle.

Furthermore, in the fishing reel of Patent Document 1, when the rotor is reversed by lever operation, the anti-reverse device can prevent the handle from rotating along with the reversal of the rotor, but it is not a structure that prevents the handle from loosening in the reverse direction. Therefore, the fishing reel of Patent Document 1, like the known general fishing reel, will loosen in the reverse direction in the drive gear shaft and the handle. Furthermore, it is desirable to develop a structure that allows the user to easily install and remove the anti-reversal device.

The present invention is a creation made to solve this problem, and provides a fishing spinning reel that can limit the reverse rotation of the handle, reduce the looseness of the handle, improve the operating feel of the handle, and can easily install and remove the reverse rotation prevention device.

In order to solve the above-mentioned problem, the present invention relates to a fishing spinning reel, comprising: a handle disposed on the reel body, and a drive gear shaft disposed on the reel body and connected to the handle. The invention also comprises a reverse rotation prevention device for limiting the reverse rotation of the drive gear shaft and the handle in a direction opposite to the winding direction of the fishing line. The reverse rotation prevention device is composed of an assembly body that can be installed and removed from the drive gear shaft.

In this fishing spinning reel, the reverse rotation of the driving gear shaft and the handle shaft is restricted in the direction opposite to the fishing line winding direction by the reverse rotation prevention device. That is, even if the driving gear shaft and the handle shaft are loosened in the reverse direction, the looseness can be appropriately reduced by the reverse rotation prevention device. Therefore, the operating feel of the handle is improved, and the fishing operability is improved. In particular, in the case of a fishing method in which the handle is wound little by little, since the handle can be stopped little by little without loosening, it is easy to sense that a fish has taken the hook, and the fishing result can be expected.

Furthermore, since the anti-reverse device is an assembly that can be attached and detached to the drive gear shaft, the user can easily attach and detach the anti-reverse device. For example, even when the anti-reverse device needs to be attached and detached when the reel body is turned over and the handle is replaced, the operation is easy. In particular, since the anti-reverse device itself can be attached and detached, even when the handle is replaced at the fishing ground, there is no need to worry about the parts falling off or being lost, and the handle can be easily replaced.

Furthermore, since the anti-reverse device can be installed and removed from the drive gear shaft according to the user's preference, the degree of freedom in fishing operation is improved. Furthermore, since it can be installed and removed, the maintenance of the anti-reverse device is also easy.

Furthermore, the anti-reverse device is preferably attachable to and detachable from the left and right ends of the driving gear shaft. In this configuration, the anti-reverse device is easily accessible, and the installation and removal of the anti-reverse device by the user is simple. Furthermore, since the anti-reverse device can be arranged using the installation space of the handle at the left and right ends of the driving gear shaft, the size of the spinning reel for fishing can be avoided, and the operating feel of the handle can be improved.

Moreover, the anti-reverse device is preferably fixed to the reel body. In this configuration, since the anti-reverse device can be fixed to the reel body, the reverse rotation of the drive gear shaft and the handle shaft can be restricted, and at the same time, it is suitable for reducing the looseness.

Furthermore, the anti-reverse device is a rolling one-way clutch, and the inner ring of the rolling one-way clutch is preferably the driving gear shaft or a cylindrical component mounted on the driving gear shaft.

In this structure, the handle shaft and the reverse rotation of the handle can be reduced at a low cost by using the highly versatile parts of the rolling one-way clutch. Thus, the loosening of the handle shaft can be prevented appropriately.

Furthermore, the outer ring of the anti-reversal device is formed into a non-linearly symmetrical shape when viewed from the axial direction, and the opposite wall of the reel body to the outer ring is formed into a shape corresponding to the outer ring, preferably having a portion that is non-linearly symmetrical when viewed from the axial direction.

In this structure, when the anti-reverse device is mounted on the drive gear shaft or the cylindrical member externally fitted on the drive gear shaft, if the anti-reverse device is in the wrong direction with respect to the reel body, the outer ring of the anti-reverse device and the opposing wall of the reel body do not coincide, and assembly cannot be performed. Therefore, incorrect assembly can be prevented.

According to the spinning reel for fishing of the present invention, the reverse rotation of the handle can be restricted, and at the same time, the looseness of the handle can be reduced, and the operating feeling of the handle can be improved. Moreover, according to the spinning reel for fishing of the present invention, the reverse rotation prevention device can be easily installed and removed.

The spinning reel R1 for fishing related to each embodiment will be described with reference to the drawings. In the following description, "front and back" and "up and down" are based on the direction shown in FIG. 1, and "left and right" are based on the direction shown in FIG. 2. In each embodiment, the same parts are assigned the same symbols and detailed description is omitted.

(First embodiment) The fishing spinning reel R1 of this embodiment is equipped with a first anti-reverse device 50 for limiting the reverse rotation of the drive shaft 7 (rotor 4) and a second anti-reverse device 40 for limiting the reverse rotation of the drive gear shaft 2 (handle 3) as described below. In addition, the second anti-reverse device 40 corresponds to the "anti-reverse device" in the scope of the patent application.

First, the basic structure of the fishing reel R1 is described. As shown in FIG. 1 , the fishing reel R1 includes: a reel body 1 on which a handle 3 is mounted; a rotor 4 disposed on the front side of the reel body 1 and rotated by the winding operation of the handle 3; and a spool 5 disposed on the front side of the rotor 4 and reciprocating in the front and rear directions by the winding operation of the handle 3.

The reel body 1 comprises: a body 10 having a side opening 11 opening to the left; a foot 12 extending upward from the upper part of the body 10 and having a rod mounting part mounted on the fishing rod at the top; a cover member 13 blocking the side opening 11; and a protective cover 14 mounted on the rear of the body 10. In addition, the body 10 comprises: a cylindrical body front part 10A through which the drive shaft 7 and the reel shaft 8 pass (see FIG. 2). The rotor 4 is mounted on the front end of the drive shaft 7, and the reel 5 is mounted on the front end of the reel shaft 8. In addition, the body 10, the foot 12 and the body front part 10A are integrally formed of a metal material and have high strength.

As shown in FIG. 2 , the cover member 13 has a cylindrical insertion portion 13a inserted into the inner side of the side opening portion 11. An external thread (male screw) portion is formed on the outer peripheral surface of the insertion portion 13a. The external thread portion is screwed with an internal thread (female screw) portion formed on the inner peripheral surface of the side opening portion 11. By this screwing, the main body 10 and the cover member 13 are integrated.

In the main body 10, as a structure for driving the drive shaft 7 and the reel shaft 8 by operating the handle 3 in conjunction, a drive gear shaft 2 extending in the left and right directions and a reel reciprocating motion device 60 are provided. The drive gear shaft 2 has a drive gear 21 and a gear 22. The drive gear shaft 2 is rotatably supported on the cover member 13 and the main body 10 (annular portion 10a) through left and right ball bearings 15 and 16. The connecting portion 31 provided by the handle 3 is screwed onto the drive gear shaft 2. Accordingly, the handle 3 rotates integrally with the drive gear shaft 2. The details of the drive gear shaft 2 and the handle 3 will be described later.

The reel reciprocating motion device 60 has a slider 61 and a linkage gear 62, and is configured such that the slider 61 moves in the front-rear direction along a guide shaft (not shown) extending in the front-rear direction of the main body 10. The slider 61 is fixed to the rear end of the reel shaft 8 by a fixing screw 8a, and has a guide groove 61a opened on the right side. The linkage gear 62 is supported by a support member 63 provided on the right side wall of the main body 10, and engages with the gear 22 of the drive gear shaft 2 and rotates. The linkage gear 62 has an eccentric protrusion 62a that engages with the guide groove 61a of the slider 61.

As described above, when the gear shaft 2 and the gear 22 rotate by the winding operation of the handle 3, the interlocking gear 62 rotates, and its rotational motion is converted into the forward and backward motion of the slider 61 through the eccentric protrusion 62a and the guide groove 61a. Accordingly, the reel shaft 8 (reel 5) reciprocates in the forward and backward direction.

As shown in FIG. 2 , the drive shaft 7 extends in a direction perpendicular to the drive gear shaft 2 and has a hollow portion extending in the axial direction. The drive shaft 7 is rotatably supported by a front bearing 7c disposed in the front portion 10A of the main body and a rear bearing 7b disposed in the main body 10. In the hollow portion of the drive shaft 7, a reel shaft (support shaft) 8 is movably inserted in the axial direction.

The body front portion 10A is formed in a substantially cylindrical shape with the center axis O1 of the drive shaft 7 as the center. The first anti-reverse device 50, the operation cover 10B, and the magnetic fluid sealing mechanism 70 are assembled to the body front portion 10A.

The front side bearing 7c is fitted inside the rear portion of the main body front portion 10A. An annular retaining ring 55 for restricting the front side bearing 7c from falling out abuts against the front surface of the outer ring of the front side bearing 7c.

The first anti-reverse device 50 is a rolling one-way clutch that allows the drive shaft cylinder 7 to rotate forward in the fishing line winding direction, while preventing the drive shaft cylinder 7 from rotating backward. In addition, an inner ring 51 is provided on the inner circumference of the first anti-reverse device 50, and the inner ring 51 is engaged with the outer circumference of the drive shaft cylinder 7 to stop the drive shaft cylinder 7 from rotating. Therefore, the first anti-reverse device 50 controls the rotation of the drive shaft cylinder 7 through the inner ring 51.

The first anti-reversal device 50 includes: a substantially cylindrical outer ring 52, a plurality of rollers 53 disposed between the inner ring 51 and the outer ring 52, and a retainer 54 for retaining the plurality of rollers 53. The retainer 54 has a protrusion (not shown) that passes through the outer ring 52 and protrudes radially outward. If the protrusion moves in the circumferential direction, the retainer 54 rotates, and the rollers 53 exert a wedge effect between the inner ring 51 and the outer ring 52 to prevent the inner ring 51 (drive shaft cylinder 7) from reversing, or the rollers 53 do not exert a wedge effect between the inner ring 51 and the outer ring 52, allowing the inner ring 51 (drive shaft cylinder 7) to reversing.

The operating cover 10B is a cylindrical member disposed on the outer peripheral side of the main body front portion 10A. The operating cover 10B is rotatable with respect to the main body front portion 10A, and has an engaging portion (not shown) that engages with the protruding portion of the first anti-reverse device 50. Accordingly, when the user rotates the operating cover 10B, the anti-reverse state and the anti-reverse state of the first anti-reverse device 50 are switched. The operating cover 10B has an operating portion (not shown) that can be operated by the user's finger.

The magnetic fluid sealing mechanism 70 is a well-known sealing mechanism, and is a member for retaining a magnetic fluid (not shown) and sealing the opening of the front portion 10A of the body.

Next, the driving gear shaft 2, the handle 3, the second anti-reversal device 40 and the related structures of the driving gear shaft 2, the handle 3 and the second anti-reversal device 40 are described in detail. As shown in FIG. 2, the driving gear shaft 2 is roughly cylindrical, having a stepped circular outer peripheral surface along the center axis O2 and a hollow hole opened on the left and right. When the handle 3 is installed at the left end 23 of the driving gear shaft 2, the second anti-reversal device 40 is installed at the right end 24 of the driving gear shaft 2. Moreover, as shown in FIG. 5, when the handle 3 is installed at the right end 24 of the driving gear shaft 2, the second anti-reversal device 40 is installed at the left end 23 of the driving gear shaft 2.

As shown in FIG2, an outer threaded portion 23a for screwing into the connection portion 31 of the handle 3 when the left handle is used is formed on the outer circumferential surface of the left end portion 23 of the drive gear shaft 2. On the other hand, an outer threaded portion 24a for screwing into the second anti-reversal device 40 when the left handle is used is formed on the outer circumferential surface of the right end portion 24 of the drive gear shaft 2. As shown in FIG5, the outer threaded portion 23a of the left end portion 23 also functions as a mounting screw for screwing into the second anti-reversal device 40 when the right handle is used. Moreover, the outer threaded portion 24a of the right end portion 24 also functions as a mounting screw for screwing into the connection portion 31 of the handle 3 when the right handle is used. The outer threaded portion 23a of the left end portion 23 is a reverse thread in the opposite direction of the positive thread. On the other hand, the external thread portion 24a of the right end portion 24 is a positive thread.

A driving gear 21 is mounted on the outer peripheral surface of the driving gear shaft 2 at a position deviated to the left from the center in the left-right direction through a mounting pin 15a. The mounting pin 15a is arranged on the inner side of the left ball bearing 15. The left ball bearing 15 is mounted on the inner surface of the cover member 13. Furthermore, a gear 22 is integrally formed at a position deviated to the right from the center in the left-right direction of the driving gear shaft 2. The right ball bearing 16 is mounted on the inner side of the annular portion 10a of the body 10 on the right side of the gear 22.

As shown in FIG. 2 , the handle 3 has a connecting portion 31 connected to the drive gear shaft 2. The connecting portion 31 is mounted on the base end of the handle 3 through a connecting pin 32a. The connecting portion 31 is in the shape of a stepped cylinder. A small-diameter internal thread portion 31b and a large-diameter internal thread portion 31a are formed on the inner surface of the connecting portion 31. The large-diameter internal thread portion 31a is a reverse thread in the opposite direction to the normal thread, and the small-diameter internal thread portion 31b is a normal thread. In the left handle, the large-diameter internal thread portion 31a is screwed into the external thread portion 23a of the left end portion 23 of the drive gear shaft 2 and the handle 3 is mounted on the drive gear shaft 2. Moreover, in the right handle, as shown in FIG5 , the small-diameter internal threaded portion 31b is screwed into the external threaded portion 24a of the right end portion 24 of the drive gear shaft 2 and the handle 3 is mounted on the drive gear shaft 2.

Next, the second anti-reverse device 40 is described. The second anti-reverse device 40 is a device that allows the driving gear shaft 2 (handle 3) to rotate forward in the fishing line winding direction, while preventing the driving gear shaft 2 (handle 3) from rotating in reverse. The second anti-reverse device 40 is directly mounted on the driving gear shaft 2 on the opposite side of the left-right direction of the side where the handle 3 is mounted on the driving gear shaft 2. In this embodiment, a rolling one-way clutch is used as the second anti-reverse device 40.

As shown in FIG. 3A and FIG. 3B , the second anti-reversal device 40 comprises: an inner ring 41, an outer ring 42 as a ring-shaped retaining body, a plurality of rollers 43 as a rolling component, and a fastener 44. As shown in FIG. 3A , the inner ring 41 is a cylindrical component screwed to the drive gear shaft 2 and rotates together with the drive gear shaft 2. As shown in FIG. 3B , a first internal threaded portion 41a with a small diameter and a second internal threaded portion 41b with a larger diameter than the first internal threaded portion 41a are formed on the inner surface of the inner ring 41. The first internal threaded portion 41a is a screw for screwing the inner ring 41 at the right end 24 of the drive gear shaft 2, and is screwed to the external threaded portion 24a of the right end 24 of the drive gear shaft 2 as shown in FIG. 3A. On the other hand, the second internal threaded portion 41b is a screw for screwing the inner ring 41 at the left end 23 of the drive gear shaft 2, and is screwed to the external threaded portion 23a of the left end 23 of the drive gear shaft 2 as shown in FIG. 5. In addition, a protrusion 41c for locking the inner ring 41 when screwing is formed at the right end of the inner ring 41.

As shown in FIG4 , the outer ring 42 has a space between the inner ring 41 and is configured to hold a plurality of rollers 43. The outer ring 42 is in a substantially hexagonal cylindrical shape, and rollers 43 are respectively arranged in six corner regions 42b formed on the inner side of the cylinder. Each corner region 42b is separated by a partition member 49. A spring 47 is supported by the partition member 49. The partition member 49 and the rollers 43 are supported by a fastener 44 (see FIG3B ) and an annular cover 48 (see FIG3B ). A free rotation region 42c in which the rollers 43 are in a freely rotatable state and a rotation prevention region 42d in which the rotation of each roller 43 is prevented by a wedge action are respectively formed in each corner region 42b.

Six protrusions 42a protruding radially outward at predetermined intervals are formed on the outer peripheral surface of the outer ring 42. The protrusion 42a has a first surface 42a1 and a second surface 42a2, with an imaginary line O3 drawn from the center axis O2 through the top T of the protrusion 42a as a boundary. The first surface 42a1 is a curved surface that is continuous from its starting end 42e to the imaginary line O3, and is an arc-shaped surface with a small curvature radius. On the other hand, the second surface 42a2 is a curved surface that is continuous from the imaginary line O3 to the terminal end 42f, and is an arc-shaped surface with a larger curvature radius than the first surface 42a1. That is, the first surface 42a1 and the second surface 42a2 are asymmetrical in the circumferential direction with the imaginary line O3 as a boundary. Accordingly, the outer ring 42 (the second anti-reversal device 40) becomes a non-linearly symmetrical shape with the imaginary line O3 as a reference line when viewed from the center axis O2 direction.

Here, the outer ring 42 is fitted into the fixing member 18 as shown in FIG3A. The fixing member 18 is a stepped cylindrical member fixed to the right side of the body 10. The fixing member 18 has: a base 18a screwed into the annular portion 10a disposed on the right side of the body 10; an annular flange portion 18b connected to the base 18a and protruding radially inward; and an annular fixing portion 18c connected to the flange portion 18b and extending to the right side. The fixing portion 18c functions as a counter wall for fixing the outer ring 42 as described later.

Six recesses 18d are formed on the inner circumferential surface of the fixing portion 18c for inserting the protrusions 42a of the outer ring 42. As shown in FIG. 4, the recess 18d is in a shape that fits into the protrusion 42a, and is asymmetrical in the circumferential direction with the imaginary line O3 as the boundary when viewed from the center axis O2. According to this structure, the second anti-reversal device 40 is blocked from being embedded in the fixing member 18 in the direction where the shape of the protrusion 42a is inconsistent with the shape of the recess 18d. Thus, the second anti-reversal device 40 can be prevented from being incorrectly assembled. In addition, the fixing portion 18c does not need to be a continuous opposing wall in the circumferential direction, and it is sufficient to have a portion (recess 18d) that is asymmetrical in the circumferential direction with the imaginary line O3 as the boundary when viewed from the center axis O2.

As a structure corresponding to the recess 18d of the fixing member 18, a recess 13b is formed on the inner peripheral surface of the top end of the left cover member 13. The recess 13b has the same structure as the recess 18d of the fixing member 18. When the recess 13b is in the right handle, the protrusions 42a of the outer ring 42 are inserted. In the recess 13b as well, the second anti-reverse device 40 is blocked from being inserted into the fixing member 18 in the direction where the shape of the protrusion 42a is inconsistent with the shape of the recess 13b. According to this, the second anti-reverse device 40 can be prevented from being assembled incorrectly.

Each roller 43 is rollably arranged around the corner area 42b of the outer ring 42. Normally, each roller 43 is urged toward the adjacent partition member 49 by the spring 47 of the partition member 49 and is located in each rotation prevention area 42d. In each rotation prevention area 42d, each roller 43 allows the inner ring 41 (drive gear shaft 2) to rotate in the direction of the arrow X1 in FIG. 4. That is, when each roller 43 is rotated in the direction of the arrow X1 in FIG. 4 of the inner ring 41, it becomes each free rotation area 42c that can roll from each rotation prevention area 42d to the side. In the free rotation area 42c, since the rollers 43 do not restrict the rotation of the inner ring 41 relative to the outer ring 42, the rotation of the inner ring 41 relative to the outer ring 42 in the direction of arrow X1 is continuously permitted.

On the other hand, each roller 43 restricts the inner ring 41 from rotating in the direction of the arrow X2 in FIG. 4 in each rotation prevention area 42d. That is, each roller 43 stops in each rotation prevention area 42d when the inner ring 41 rotates in the direction of the arrow X2 in FIG. 4, and restricts the inner ring 41 from rotating with respect to the outer ring 42 by the wedge action. In addition, when each roller 43 is located in each free rotation area 42c, when the inner ring 41 rotates in the direction of the arrow X2 in FIG. 4, each roller 43 rolls from each free rotation area 42c to each rotation prevention area 42d by the urging force of the spring 47, and each roller 43 restricts the inner ring 41 from rotating with respect to the outer ring 42 by the wedge action in each rotation prevention area 42d.

As described above, the outer ring 42, roller 43, fastener 44 and cover 48 are formed as an assembly. In other words, the assembly can be installed and removed.

In addition, a cap 17 is installed on the fixing portion 18c of the fixing member 18 by screwing. The cap 17 covers the second anti-reversal device 40 from the side to prevent the second anti-reversal device 40 from falling off the drive gear shaft 2. A sealing member 17b is interposed between the fixing portion 18c of the fixing member 18 and the cap 17. Moreover, the cap 17 is installed on the cover member 13 by screwing when the right handle is shown in FIG. 5.

Next, the installation procedure of the second anti-reversal device 40 is explained. As shown in Figures 2 and 4, the second anti-reversal device 40 is installed on the right end 24 of the drive gear shaft 2 when the left handle is used. When installing the second anti-reversal device 40, first, the inner ring 41 is screwed to the right end 24 of the drive gear shaft 2. In this case, as shown in Figure 4, the first internal threaded portion 41a of the inner ring 41 is screwed to the external threaded portion 24a of the right end 24. In addition, when the inner ring 41 is screwed, the second internal threaded portion 41b of the inner ring 41 is withdrawn to the outer peripheral surface on the inner side of the right end 24. Moreover, the top end surface of the inner ring 41 (the left end in this case) abuts the step portion 23c of the outer peripheral portion of the drive gear shaft 2.

Then, the outer ring 42, roller 43, fastener 44 and cover 48 constituting the assembly are installed. In this case, the protrusion 42a of the outer ring 42 of the assembly is aligned with the recess 18d of the fixing portion 18c of the fixing member 18 while aligning the direction of the assembly, and the assembly is inserted into the inner side of the fixing portion 18c.

Then, the cover 17 is screwed to the fixing portion 18c of the fixing member 18. Thus, the second anti-reverse rotation device 40 is mounted on the right end portion 24 of the drive gear shaft 2.

Next, the installation procedure of the second anti-reverse device 40 when the handle is right is described. When the handle is right, as shown in FIG5 , the second anti-reverse device 40 is installed at the left end 23 of the drive gear shaft 2. In addition, in any case of the left end 23 and the right end 24 of the drive gear shaft 2, the installation posture of the second anti-reverse device 40 with respect to the center axis O2 is the same.

In the installation procedure of the second anti-reverse device 40 when the right handle is used, the assembly is installed after the inner ring 41 is installed on the left end portion 23 of the drive gear shaft 2. The inner ring 41 is installed by screwing the second inner threaded portion 41b of the inner ring 41 into the outer threaded portion 23a of the left end portion 23. Then, while aligning the direction of the assembly, the protrusion 42a of the outer ring 42 of the assembly is aligned with the recess 13b of the cover member 13, and the assembly is inserted into the inner side of the top end of the cover member 13.

Then, the cover 17 is screwed onto the cover member 13. Thus, the second anti-reverse device 40 is mounted on the left end portion 23 of the drive gear shaft 2.

According to the spinning reel R1 for fishing of the present embodiment described above, the second anti-reverse device 40 restricts the reverse rotation of the drive gear shaft 2 and the handle 3 in the direction opposite to the fishing line winding direction. That is, even if the drive gear shaft 2 and the handle 3 are loosened in the reverse direction due to the backlash generated by the engagement of the drive shaft cylinder 7 and the drive gear shaft 2, the second anti-reverse device 40 can appropriately reduce the looseness. Therefore, the operating feel of the handle 3 is improved, and the fishing operability is improved. In particular, in the case of a fishing method in which the handle 3 is wound little by little, since the handle 3 can be stopped little by little without loosening, it is easy to sense that a fish has bitten the hook, and the fishing result can be expected.

Furthermore, since the second anti-reverse device 40 is an assembly body that can be mounted and disassembled with respect to the drive gear shaft 2, the second anti-reverse device 40 can be easily mounted and disassembled by the user. For example, even when the reel body 1 is turned over and the handle 3 is replaced, the second anti-reverse device 40 needs to be mounted and disassembled, and the operation is easy. In particular, since the second anti-reverse device 40 itself can be mounted and disassembled, even when the handle 3 is replaced at the fishing ground, there is no need to worry about the parts falling off or being lost, and the handle 3 can be easily replaced. Furthermore, there is no need for ultra-high-precision backlash elimination during manufacturing.

Furthermore, since the second anti-reverse device 40 can be installed and removed from the drive gear shaft 2 according to the user's preference, the degree of freedom of fishing operation is improved. Furthermore, since it can be installed and removed, the maintenance of the second anti-reverse device 40 is also easy.

Furthermore, since the second anti-reverse device 40 can be installed and removed from the left and right ends 23 and 24 of the driving gear shaft 2, it is easy to access, and the installation and removal operation of the anti-reverse device by the user is simple. Furthermore, since the second anti-reverse device 40 can be arranged using the installation space of the handle 3 in the left and right ends 23 and 24 of the driving gear shaft 2, the enlargement of the fishing spinning reel R1 can be avoided, and the operating feel of the handle 3 can be improved.

Furthermore, since the second anti-reverse device 40 fixes the reel body 1 (fixing member 18), the reverse rotation of the drive gear shaft 2 and the handle 3 can be restricted, and at the same time, it is suitable for reducing the looseness.

Furthermore, since the second anti-reverse device 40 is a rolling one-way clutch, the structure suitable for reducing the looseness of the handle 3 is simple and inexpensive. Furthermore, since the second anti-reverse device 40 is a rolling one-way clutch, the fish will not be hooked when the handle 3 is rotated, which will damage the operating feel.

Moreover, since the second anti-reverse device 40 is a rolling one-way clutch and the inner ring 41 is a cylindrical component mounted on the drive gear shaft 2, the highly versatile parts of the rolling one-way clutch can be used to inexpensively limit the reverse rotation of the drive gear shaft 2 and the handle 3, and at the same time, it is suitable for preventing the drive gear shaft 2 and the handle 3 from loosening.

(Second embodiment) The second embodiment of the fishing spinning reel is described with reference to Fig. 6 and Fig. 7. This embodiment is different from the first embodiment in that the handle 3 is a handle shaft 33 that is inserted into the hollow portion of the drive gear shaft 2A, and the second anti-reverse device 40A is mounted on the auxiliary shaft 35 that is inserted into the hollow portion of the drive gear shaft 2A. The auxiliary shaft 35 is inserted into the hollow portion from the right side of the drive gear shaft 2A when the handle is left, as shown in Fig. 6, and is inserted into the hollow portion from the left side of the drive gear shaft 2A when the handle is right, as shown in Fig. 7.

As shown in FIG6 , the drive gear shaft 2A has an integrally formed drive gear 21 and a handle shaft 33. The handle shaft 33 has: a large-diameter base 33a connected to the handle 3; and a small-diameter insertion portion 33b that is continuous with the base 33a and has a smaller diameter than the base 33a and is inserted into the hollow portion of the drive gear shaft 2A.

The insertion portion 33b includes a first insertion portion 33b1 connected to the right end of the base portion 33a and a second insertion portion 33b2 connected to the first insertion portion 33b1. In other words, the insertion portion 33b is tapered toward the outer peripheral surface of the top end.

The outer circumferential surface of the first insertion portion 33b1 is formed with an inner thread outer thread that is screwed into the large diameter inner circumferential surface on the left opening side of the drive gear shaft 2A. On the other hand, the outer circumferential surface of the second insertion portion 33b2 is formed with an inner thread outer thread that is screwed into the small diameter inner circumferential surface on the right inner side of the drive gear shaft 2A (see FIG. 7). The outer thread of the first insertion portion 33b1 is a reverse thread in the opposite direction to the normal thread. The outer thread of the second insertion portion 33b2 is a normal thread.

A step surface 36 that functions as a contact portion is integrally provided at the boundary portion between the base 33a of the handle shaft 33 and the first insertion portion 33b1. The step surface 36 is formed by utilizing the outer diameter difference between the base 33a and the first insertion portion 33b1, and is an annular flat surface orthogonal to the center axis O2. The step surface 36 faces the left end portion 23A (left end surface) of the drive gear shaft 2A and the left side surface of the inner ring of the left ball bearing 15, and is configured to contact the left end portion 23A (left end surface) of the drive gear shaft 2A and the left side surface of the inner ring of the left ball bearing 15 when the handle shaft 33 is locked to the drive gear shaft 2A.

The auxiliary shaft 35 is a shaft that is installed in the hollow part of the drive gear shaft 2A by screwing. As shown in FIG6 , the auxiliary shaft 35 has: a large-diameter base 35a; and a small-diameter insertion part 35b that is continuous with the base 35a and has a smaller diameter than the base 35a and is inserted into the hollow part of the drive gear shaft 2A. A ring-shaped flange 35c that protrudes radially outward is formed at the left end of the base 35a. A protrusion 35a1 for locking the auxiliary shaft 35 when screwing is formed at the right end of the base 35a.

The insertion portion 35b includes a first insertion portion 35b1 connected to the left end of the base portion 35a and a second insertion portion 35b2 connected to the first insertion portion 35b1. In other words, the insertion portion 35b is tapered toward the outer peripheral surface of the top end.

The outer circumferential surface of the second insertion portion 35b2 is formed with an inner thread outer thread that is screwed into the small diameter inner circumferential surface on the right inner side of the drive gear shaft 2A. On the other hand, the outer circumferential surface of the first insertion portion 35b1 is formed with an inner thread outer thread that is screwed into the large diameter inner circumferential surface on the left opening side of the drive gear shaft 2A. The outer thread of the first insertion portion 35b1 is a reverse thread in the opposite direction to the normal thread. The outer thread of the second insertion portion 35b2 is a normal thread.

The left side surface of the flange portion 35c is an annular flat surface orthogonal to the center axis O2. The left side surface of the flange portion 35c faces the right end portion 24A (right end surface) of the drive gear shaft 2A, and is configured to abut the right end portion 24A (right end surface) of the drive gear shaft 2A when the handle shaft 33 is locked to the drive gear shaft 2A.

The second anti-reverse rotation device 40A does not have the inner ring 41 (see FIG. 3A ) described in the first embodiment, and is composed of only an assembly consisting of an outer ring 42, a roller 43, a fastener 44, and a cover 48. In other words, the second anti-reverse rotation device 40A is a structure in which the roller 43 directly abuts against the outer peripheral surface of the base 35a of the auxiliary shaft 35, thereby restricting the reverse rotation of the drive gear shaft 2A and the handle 3 through the auxiliary shaft 35.

Next, the installation procedure of the second anti-reverse device 40A is described. The second anti-reverse device 40A is installed through the auxiliary shaft 35 installed on the right side of the drive gear shaft 2A when the left handle is shown in Figure 6. When installing the second anti-reverse device 40A, first, the auxiliary shaft 35 is inserted from the right side of the drive gear shaft 2A and screwed into the hollow part.

Then, the outer ring 42, roller 43, fastener 44 and cover 48 constituting the assembly are installed between the base 35a and the fixing member 18. In this case, the protrusion 42a of the outer ring 42 of the assembly is aligned with the recess 18d of the fixing portion 18c of the fixing member 18 while aligning the direction of the assembly, and the assembly is inserted into the inner side of the fixing portion 18c.

Then, the cover 17 is screwed to the fixing portion 18c of the fixing member 18. Thus, the second anti-reverse rotation device 40A is mounted on the right side of the drive gear shaft 2A.

Next, the installation procedure of the second anti-reversal device 40A for the right handle is described. For the right handle, as shown in FIG7 , the second anti-reversal device 40A is installed on the left side of the drive gear shaft 2A through the auxiliary shaft 35. In this case, the assembly is installed after the auxiliary shaft 35 is installed on the left side of the drive gear shaft 2A. When installing the assembly, the recess 13b of the cover member 13 is aligned with the protrusion 42a of the outer ring 42 of the assembly, and the assembly is inserted into the inner side of the top end of the cover member 13.

Then, the cover 17 is screwed onto the cover member 13. Thus, the second anti-reverse rotation device 40A is mounted on the left side of the drive gear shaft 2A.

According to the present embodiment described above, the same effects as those of the first embodiment can be obtained. In addition, in the present embodiment, since the second anti-reversal device 40A does not have the relatively small inner ring 40 described in the first embodiment, the installation and removal of the second anti-reversal device 40A is easy to carry out.

Although the embodiments of the present invention have been described above, the present invention is not limited to the examples shown in the embodiments. For example, in the first and second embodiments described above, the second anti-reverse device 40, 40A is installed on the left and right ends of the drive gear shaft 2, 2A or the auxiliary shaft 35, but it is not limited to this, and the second anti-reverse device 40, 40A may be installed by interposing other components.

Furthermore, although a rolling one-way clutch is used as the second anti-reverse device 40, 40A in the aforementioned embodiments, the present invention is not limited thereto, and various types of anti-reverse devices such as a cam type or other anti-reverse devices may be used.
