Description

[Technical Field]

[0001] The present invention relates to a spinning fishing reel. [Background technology]

[0002] Conventionally, fishing spinning reels equipped with a reverse rotation prevention device on the drive shaft tube have been known. The reverse rotation prevention device has the function of allowing the drive shaft tube and the rotor attached to the drive shaft tube to rotate in the fishing line winding direction while preventing rotation in the opposite reverse direction (hereinafter simply referred to as "reverse rotation"). Fishing spinning reels are configured such that the drive gear shaft is mechanically connected via a drive gear that meshes with the pinion of the drive shaft tube, and the reverse rotation prevention device prevents the handle attached to the drive gear shaft from rotating reversely.

[0003] On the other hand, there is known a fishing spinning reel in which a reverse rotation prevention device is disposed on a drive gear shaft (see, for example, Patent Document 1). The spinning fishing reel of Patent Document 1 allows the rotor to rotate in the reverse direction by operating a lever, and to achieve this, the reverse prevention device is removed from the drive shaft. In the spinning fishing reel of Patent Document 1, the reverse prevention device located on the drive gear shaft prevents the reverse driving force from being transmitted to the handle when the rotor is rotated in the reverse direction by operating the lever, preventing the handle from rotating in the reverse direction together with the rotor. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6518520 Summary of the Invention [Problem to be solved by the invention]

[0005] In conventional spinning reels for fishing, backlash caused by the meshing of the pinion of the drive shaft and the drive gear can cause rattle in the drive gear shaft and the handle in the reverse direction. In particular, when fishing using a method that requires small, quick movements of the handle to reel in the line, rattle can occur every time the handle is stopped, which can impair the feel of the handle when in operation.

[0006] Furthermore, in the fishing spinning reel of Patent Document 1, when the rotor is rotated in reverse by operating the lever, the reverse rotation prevention device can prevent the handle from rotating along with the rotor's reverse rotation, but the structure is not designed to prevent the handle from rattling in the reverse direction. As a result, the fishing spinning reel of Patent Document 1, like conventional general fishing spinning reels, can experience rattle in the drive gear shaft and handle in the reverse direction.

[0007] The present invention was created to solve such problems, and its object is to provide a fishing spinning reel that can effectively reduce handle backlash while restricting reverse rotation of the handle, thereby improving the operating feel of the handle. [Means for solving the problem]

[0008] In order to solve the above problems, the fishing spinning reel according to the present invention comprises a reel body Can be mounted on the left or right side of The reel reel includes a handle, a drive gear shaft attached to the reel body and connected to the handle, and a drive shaft sleeve supported by the reel body and driven to rotate in the line-winding direction via the drive gear shaft when the handle is operated to wind the line. A first reverse prevention device is disposed between the reel body and the drive shaft sleeve to prevent the drive shaft sleeve from rotating in the opposite direction to the line-winding direction. A second reverse prevention device is disposed between the reel body and the drive gear shaft to prevent the drive gear shaft and the handle from rotating in the opposite direction to the line-winding direction. The second reverse prevention device is configured to be attachable to and detachable from the drive gear shaft.

[0009] In this fishing spinning reel, the first reverse prevention device prevents the drive shaft from rotating in the opposite direction to the fishing line winding direction, and the second reverse prevention device prevents the drive gear shaft and handle from rotating in the opposite direction to the fishing line winding direction. In other words, even if backlash caused by the meshing of the drive shaft and drive gear shaft causes rattle in the reverse direction of the drive gear shaft and handle, the second reverse prevention device can effectively reduce this. This improves the handle's operating feel and enhances fishing operability. In particular, when using a fishing method that requires small, quick reeling operations of the handle, the handle can be stopped in small, quick steps without rattle, making it easier to sense a fish bite and improving fishing results.

[0010] In addition, the second reverse prevention device The reel body has a left and right end portion. It is preferable that the second reverse rotation prevention device is fixed to the reel body. With this configuration, since the second reverse rotation prevention device can be fixed to the reel body, backlash can be suitably reduced while restricting reverse rotation of the drive gear shaft and handle.

[0011] It is also preferable that the second reverse prevention device is disposed near the end of the drive gear shaft or near the bearing that rotatably supports the drive gear shaft. In this configuration, the second reverse prevention device can be efficiently disposed by utilizing the space where the handle is attached to the drive gear shaft and the space near the bearing inside the reel body.

[0012] It is preferable that the second reverse prevention device is a rolling one-way clutch, and the inner ring of the rolling one-way clutch is the drive gear shaft or a cylindrical member attached to the drive gear shaft.

[0013] In this configuration, a rolling one-way clutch, which is a highly versatile component, can be used to inexpensively restrict reverse rotation of the drive gear shaft and the handle, while suitably preventing rattle of the drive gear shaft and the handle. [Effects of the Invention]

[0014] According to the fishing spinning reel of the present invention, it is possible to appropriately reduce the rattle of the handle while restricting the reverse rotation of the handle, thereby improving the operating feel of the handle. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] A fishing spinning reel R1 according to each embodiment will be described with reference to the drawings. In the following description, "front and back" and "up and down" refer to the directions shown in Fig. 1, and "left and right" refer to the directions shown in Fig. 2. In each embodiment, the same parts are designated by the same reference numerals, and detailed descriptions will be omitted.

[0017] (First embodiment) As will be described later, the fishing spinning reel R1 of this embodiment is equipped with a first reverse prevention device 50 that regulates reverse rotation of the drive shaft cylinder 7 (rotor 4), and a second reverse prevention device 40 that regulates reverse rotation of the drive gear shaft 2 (handle 3).

[0018] First, the basic structure of the fishing spinning reel R1 will be explained. As shown in Figure 1, a fishing spinning reel R1 comprises a reel body 1 to which a handle 3 is attached, a rotor 4 provided in front of the reel body 1 and rotated by the winding operation of the handle 3, and a spool 5 provided in front of the rotor 4 and reciprocating back and forth by the winding operation of the handle 3.

[0019] The reel body 1 comprises a body 10 having a side opening 11 that opens toward the left side, legs 12 that extend upward from the top of the body 10 and have a rod attachment portion at their tip that is attached to a fishing rod, a cover member 13 that closes the side opening 11, and a protective cover 14 attached to the rear of the body 10. The body 10 also comprises a cylindrical front body portion 10A (see Figure 2) through which the drive shaft tube 7 and spool shaft 8 pass. The rotor 4 is attached to the front end of the drive shaft tube 7, and the spool 5 is attached to the front end of the spool shaft 8. The body 10, the legs 12, and the front body portion 10A are integrally formed from a metal material and have high strength.

[0020] As shown in Fig. 2, the cover member 13 has a cylindrical insertion portion 13a that is inserted into the inside of the side opening 11. A male thread is formed on the outer peripheral surface of the insertion portion 13a. The male thread is threaded into a female thread formed on the inner peripheral surface of the side opening 11. This threading unites the body 10 and the cover member 13 together.

[0021] Within the body 10, there are provided a drive gear shaft 2 extending in the left-right direction and a spool reciprocating device 60 as components for driving the drive shaft cylinder 7 and the spool shaft 8 in conjunction with the operation of the handle 3. The drive gear shaft 2 includes a drive gear 21 and a gear 22. The drive gear shaft 2 is rotatably supported by the cover member 13 and the body 10 (annular portion 10a) via left and right ball bearings 15, 16. A connecting portion 31 provided on the handle 3 is screwed onto the drive gear shaft 2, so that the handle 3 and the drive gear shaft 2 rotate together. Details of the drive gear shaft 2 and the handle 3 will be described later.

[0022] The spool reciprocating device 60 includes a slider 61 and an interlocking gear 62, and is configured so that the slider 61 moves in the front-to-rear direction along a guide shaft (not shown) that extends in the front-to-rear direction of the body 10. The slider 61 is fixed to the rear end of the spool shaft 8 with a fixing screw 8a, and includes a guide groove 61a that opens to the right side. The interlocking gear 62 is supported by a support member 63 provided on the right wall of the body 10, and rotates in mesh with the gear 22 of the drive gear shaft 2. The interlocking gear 62 includes an eccentric protrusion 62a that engages with the guide groove 61a of the slider 61.

[0023] As described above, when the drive gear shaft 2 and gear 22 rotate due to the reeling operation of the handle 3, the interlocking gear 62 rotates, and this rotational motion is converted into the forward and backward motion of the slider 61 via the eccentric protrusion 62a and the guide groove 61a. This causes the spool shaft 8 (spool 5) to reciprocate in the forward and backward directions.

[0024] 2, the drive shaft cylinder 7 extends in a direction perpendicular to the drive gear shaft 2 and has a hollow portion extending axially therein. The drive shaft cylinder 7 is rotatably supported via a front bearing 7c provided in the front body portion 10A and a rear bearing 7b provided in the body 10. A spool shaft (support shaft) 8 is inserted into the hollow portion of the drive shaft cylinder 7 so as to be axially movable.

[0025] The front body portion 10A is formed in a substantially cylindrical shape centered on the central axis O1 of the drive shaft cylinder 7. A first reverse prevention device 50, an operation cover 10B, and a magnetic fluid seal mechanism 70 are assembled to the front body portion 10A.

[0026] A front bearing 7c is fitted inside the rear part of the front body part 10A. A ring-shaped retaining ring 55 that prevents the front bearing 7c from falling off is in contact with the front surface of the outer ring of the front bearing 7c.

[0027] The first reverse prevention device 50 is a rolling one-way clutch that prevents the drive shaft cylinder 7 from rotating in the reverse direction while allowing the drive shaft cylinder 7 to rotate in the normal direction, which is the fishing line winding direction. An inner ring 51 is provided on the inner peripheral side of the first reverse prevention device 50 so as to be fitted onto the outer peripheral surface of the drive shaft cylinder 7 and thereby prevented from rotating by the drive shaft cylinder 7. Therefore, the first reverse prevention device 50 controls the rotation of the drive shaft cylinder 7 via the inner ring 51.

[0028] The first reverse prevention device 50 includes a substantially cylindrical outer ring 52, a plurality of rollers 53 arranged between the inner ring 51 and the outer ring 52, and a retainer 54 that holds the plurality of rollers 53. The retainer 54 is formed with a protrusion (not shown) that penetrates the outer ring 52 and protrudes radially outward. When the protrusion moves in the circumferential direction, the retainer 54 rotates, and the rollers 53 exert a wedge action between the inner ring 51 and the outer ring 52, preventing the inner ring 51 (drive shaft cylinder 7) from rotating in the reverse direction, or the rollers 53 do not exert a wedge action between the inner ring 51 and the outer ring 52, allowing the inner ring 51 (drive shaft cylinder 7) to rotate in the reverse direction.

[0029] The operation cover 10B is a cylindrical member arranged on the outer periphery of the front body part 10A. The operation cover 10B is rotatable relative to the front body part 10A and has an engaging part (not shown) that engages with the protruding part of the first reverse prevention device 50. As a result, when the user rotates the operation cover 10B, the first reverse prevention device 50 switches between a reverse prevention state and a reverse permission state. The operation cover 10B has an operating part (not shown) that can be operated by the user's fingers.

[0030] The magnetic fluid seal mechanism 70 is a known seal mechanism that holds a magnetic fluid (not shown) and seals the opening of the body front portion 10A.

[0031] Next, the drive gear shaft 2, the handle 3, the second reverse prevention device 40 and their related structures will be described in detail. As shown in Fig. 2, the drive gear shaft 2 is generally cylindrical, with a stepped circular outer periphery along the central axis O2 and a hollow hole that opens to the left and right. When the handle 3 is attached to the left end 23 of the drive gear shaft 2, a second reverse prevention device 40 is attached to the right end 24 of the drive gear shaft 2. Furthermore, as shown in Fig. 5, when the handle 3 is attached to the right end 24 of the drive gear shaft 2, the second reverse prevention device 40 is attached to the left end 23 of the drive gear shaft 2.

[0032] 2, a male thread portion 23a is formed on the outer peripheral surface of the left end portion 23 of the drive gear shaft 2 for threading with the connecting portion 31 of the handle 3 when the handle is in left-hand mode. On the other hand, a male thread portion 24a is formed on the outer peripheral surface of the right end portion 24 of the drive gear shaft 2 for threading with the second reverse prevention device 40 when the handle is in left-hand mode. 5, the male thread portion 23a of the left end portion 23 also functions as a mounting screw for screwing in the second reverse prevention device 40 when the handle is right-hand driven. Also, the male thread portion 24a of the right end portion 24 also functions as a mounting screw for screwing in the connecting portion 31 of the handle 3 when the handle is right-hand driven. The male thread portion 23a of the left end portion 23 is a reverse thread, which is opposite to a normal thread, whereas the male thread portion 24a of the right end portion 24 is a normal thread.

[0033] A drive gear 21 is attached to the outer peripheral surface of the drive gear shaft 2 via a mounting pin 15a at a position offset to the left from the center in the left-right direction. The mounting pin 15a is disposed inside the left ball bearing 15. The left ball bearing 15 is attached to the inner surface of the cover member 13. A gear 22 is integrally formed at a position offset to the right from the center in the left-right direction of the drive gear shaft 2. The right ball bearing 16 is attached to the inside of the annular portion 10a of the body 10, to the right of the gear 22.

[0034] As shown in FIG. 2, the handle 3 has a connecting portion 31 that is connected to the drive gear shaft 2. The connecting portion 31 is attached to the base end of the handle 3 via a connecting pin 32a. The connecting portion 31 has a stepped cylindrical shape. A small-diameter female thread portion 31b and a large-diameter female thread portion 31a are formed on the inner surface of the connecting portion 31. The large-diameter female thread portion 31a is a reverse thread that is opposite to a positive thread, and the small-diameter female thread portion 31b is a positive thread. When the handle is on the left side, the large-diameter female thread portion 31a is threaded into the male thread portion 23a at the left end portion 23 of the drive gear shaft 2, and the handle 3 is attached to the drive gear shaft 2. When the handle is on the right side, the small-diameter female thread portion 31b is threaded into the male thread portion 24a at the right end portion 24 of the drive gear shaft 2, and the handle 3 is attached to the drive gear shaft 2, as shown in FIG.

[0035] Next, the second reverse prevention device 40 will be described. The second reverse prevention device 40 is a device that prevents the drive gear shaft 2 (handle 3) from rotating in the reverse direction while allowing the drive gear shaft 2 (handle 3) to rotate in the normal direction, which is the fishing line winding direction. The second reverse prevention device 40 is attached directly to the drive gear shaft 2 on the side opposite in the left-right direction to the side on which the handle 3 is attached. In this embodiment, a rolling-type one-way clutch is used as the second reverse prevention device 40.

[0036] As shown in FIGS. 3A and 3B, the second reverse prevention device 40 has an inner ring 41, an outer ring 42 as an annular retainer, a plurality of rollers 43 as rolling members, and a retainer 44. As shown in FIG. 3A, the inner ring 41 is a cylindrical member that is threaded onto the drive gear shaft 2 and rotates together with the drive gear shaft 2. As shown in FIG. 3B, a first female thread 41a having a small diameter and a second female thread 41b having a larger diameter than the first female thread 41a are formed on the inner surface of the inner ring 41. The first female thread 41a is a thread for threading the inner ring 41 onto the right end 24 of the drive gear shaft 2, and as shown in FIG. 3A, is threaded into the male thread 24a of the right end 24 of the drive gear shaft 2. On the other hand, the second female thread 41b is a thread for threading the inner ring 41 onto the left end 23 of the drive gear shaft 2, and as shown in FIG. 5, is threaded into the male thread 23a of the left end 23 of the drive gear shaft 2. A protrusion 41c is formed on the right end of the inner ring 41 to fasten the inner ring 41 when screwed together.

[0037] As shown in FIG. 4, the outer ring 42 is disposed between itself and the inner ring 41 with a gap therebetween that allows the rollers 43 to be held. The outer ring 42 has a generally hexagonal cylindrical shape, with the rollers 43 disposed in six corner regions 42b formed inside the cylindrical portion. 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 retainer 44 (see FIG. 3B) and a ring-shaped cover 48 (see FIG. 3B). Each corner region 42b is formed with a free rotation region 42c in which the rollers 43 are free to rotate, and a rotation prevention region 42d that prevents rotation of each roller 43 by wedging action.

[0038] Six protrusions 42a are formed on the outer peripheral surface of the outer ring 42, protruding radially outward at predetermined intervals. Each protrusion 42a has a first surface 42a1 and a second surface 42a2, with a boundary defined by an imaginary line O3 drawn from the central axis O2 through the apex T of the protrusion 42a. The first surface 42a1 is a curved surface that continues from its starting point 42e to the imaginary line O3 and is an arc-shaped surface with a small radius of curvature. On the other hand, the second surface 42a2 is a curved surface that continues from the imaginary line O3 to its terminal end 42f and is an arc-shaped surface with a larger radius of curvature than the first surface 42a1. In other words, the first surface 42a1 and the second surface 42a2 are asymmetric in the circumferential direction with respect to the imaginary line O3. As a result, the outer ring 42 (second reverse prevention device 40) has an asymmetrical shape with the imaginary line O3 as a reference line when viewed from the direction of the central axis O2.

[0039] 3A, the outer ring 42 is fitted to a fixed member 18. The fixed member 18 is a stepped cylindrical member fixed to the right side of the body 10. The fixed member 18 includes a base portion 18a that is threadedly fitted to an annular portion 10a provided on the right side of the body 10, an annular flange portion 18b that is continuous with the base portion 18a and protrudes radially inward, and an annular fixing portion 18c that is continuous with the flange portion 18b and extends to the right.

[0040] Six recesses 18d are formed on the inner peripheral surface of the fixed portion 18c, into which the respective protrusions 42a of the outer ring 42 are inserted. As shown in FIG. 4, the recesses 18d are shaped to fit the protrusions 42a, and are asymmetric in the circumferential direction across the imaginary line O3 when viewed from the direction of the central axis O2. With this configuration, if the shape of the recesses 18d does not match the shape of the protrusions 42a, fitting of the second reverse prevention device 40 into the fixed member 18 is hindered. This makes it possible to prevent incorrect assembly of the second reverse prevention device 40. The fixing portion 18c does not need to be a circumferentially continuous opposing wall, but may have a portion (recess 18d) that is asymmetric in the circumferential direction across the imaginary line O3 when viewed from the direction of the central axis O2.

[0041] As a structure corresponding to the recess 18d of the fixing member 18, a recess 13b is formed on the inner peripheral surface at the tip end of the left-side cover member 13. The recess 13b has the same configuration as the recess 18d of the fixing member 18. When the handlebars are right-hand drive, the protrusions 42a of the outer ring 42 are inserted into the recesses 13b. Similarly, in this recess 13b, if the shape of the protrusions 42a does not match the shape of the recess 13b, the second reverse prevention device 40 cannot be fitted into the fixing member 18. This makes it possible to prevent incorrect assembly of the second reverse prevention device 40.

[0042] Each roller 43 is disposed rollably around a corner region 42b of the outer ring 42. Normally, each roller 43 is biased toward an adjacent partition member 49 by a spring 47 of the partition member 49 and is located in a rotation-blocking region 42d. In each rotation-blocking region 42d, each roller 43 allows the inner ring 41 (drive gear shaft 2) to rotate in the direction of arrow X1 in FIG. 4. That is, when the inner ring 41 rotates in the direction of arrow X1 in FIG. 4, each roller 43 can roll from the rotation-blocking region 42d to a corresponding free rotation region 42c to the side. In the free rotation region 42c, each roller 43 does not restrict rotation of the inner ring 41 relative to the outer ring 42, so rotation of the inner ring 41 relative to the outer ring 42 in the direction of arrow X1 is continuously permitted.

[0043] Meanwhile, in each rotation prevention region 42d, each roller 43 restricts rotation of the inner ring 41 in the direction of arrow X2 in Fig. 4. That is, when the inner ring 41 rotates in the direction of arrow X2 in Fig. 4, each roller 43 remains in the corresponding rotation prevention region 42d and restricts rotation of the inner ring 41 relative to the outer ring 42 by wedging action. Note that when each roller 43 is located in a free rotation region 42c and the inner ring 41 rotates in the direction of arrow X2 in Fig. 4, the biasing force of the spring 47 causes each roller 43 to roll from the free rotation region 42c to the corresponding rotation prevention region 42d, and each roller 43 restricts rotation of the inner ring 41 relative to the outer ring 42 by wedging action in the rotation prevention region 42d.

[0044] The outer ring 42, roller 43, retainer 44 and lid 48 as described above are configured as a single assembly, which means that they can be attached and detached as an assembly.

[0045] A cap 17 is attached by screwing to the fixing portion 18c of the fixing member 18. The cap 17 covers the second reverse prevention device 40 from the side and prevents the second reverse prevention device 40 from falling off the drive gear shaft 2. A seal member 17b is interposed between the fixing portion 18c of the fixing member 18 and the cap 17. In addition, when the handle is right-hand drive, the cap 17 is attached to the cover member 13 by screwing, as shown in FIG.

[0046] Next, the procedure for installing the second reverse prevention device 40 will be described. As shown in FIGS. 2 and 4, the second reverse prevention device 40 is installed on the right end 24 of the drive gear shaft 2 when the handle is left-hand. When installing the second reverse prevention device 40, first, the inner ring 41 is threaded onto the right end 24 of the drive gear shaft 2. In this case, as shown in FIG. 4, the first female thread portion 41a of the inner ring 41 is threaded onto the male thread portion 24a of the right end 24. When the inner ring 41 is threaded, the second female thread portion 41b of the inner ring 41 is released onto the outer peripheral surface at the back side of the right end 24. In addition, the tip end portion (in this case, the left end portion) of the inner ring 41 abuts against the stepped portion 23c on the outer periphery of the drive gear shaft 2.

[0047] Thereafter, the outer ring 42, roller 43, retainer 44, and lid 48 configured as an assembly are attached. In this case, while adjusting the orientation of the assembly, the protruding portion 42a of the outer ring 42 of the assembly is aligned with the recessed portion 18d of the fixing portion 18c of the fixing member 18, and the assembly is inserted inside the fixing portion 18c.

[0048] Thereafter, the cap 17 is screwed onto the fixing portion 18c of the fixing member 18. As a result, the second reverse prevention device 40 is attached to the right end portion 24 of the drive gear shaft 2.

[0049] Next, the procedure for installing the second reverse prevention device 40 when the handle is right-hand will be described. When the handle is right-hand, the second reverse prevention device 40 is installed on the left end 23 of the drive gear shaft 2, as shown in Figure 5. The installation posture of the second reverse prevention device 40 relative to the center axis O2 is the same whether it is installed on the left end 23 or the right end 24 of the drive gear shaft 2.

[0050] In the procedure for installing the second reverse stop device 40 in a right-hand drive system, the inner ring 41 is also installed on the left end 23 of the drive gear shaft 2, and then the assembly is installed. The inner ring 41 is installed by screwing the second female thread portion 41b of the inner ring 41 into the male thread portion 23a of the left end 23. Then, while adjusting the orientation of the assembly, the protruding portion 42a of the outer ring 42 of the assembly is aligned with the recessed portion 13b of the cover member 13, and the assembly is inserted inside the tip of the cover member 13.

[0051] Thereafter, the cap 17 is screwed onto the cover member 13. As a result, the second reverse prevention device 40 is attached to the left end portion 23 of the drive gear shaft 2.

[0052] In the fishing spinning reel R1 of this embodiment described above, the first reverse prevention device 50 prevents the drive shaft cylinder 7 from rotating in the reverse direction opposite to the fishing line winding direction, and the second reverse prevention device 40 prevents the drive gear shaft 2 and handle 3 from rotating in the reverse direction opposite to the fishing line winding direction. In other words, even if backlash caused by the meshing of the drive shaft cylinder 7 and the drive gear shaft 2 causes rattles in the reverse direction of the drive gear shaft 2 and handle 3, the second reverse prevention device 40 can effectively reduce this rattle. This improves the operating feel of the handle 3 and enhances fishing operability. In particular, when fishing by operating the handle 3 in short, short steps to reel in the line, the handle 3 can be stopped in short, short steps without rattles, making it easier to sense a fish bite and improving fishing results.

[0053] In addition, because second reverse prevention device 40 is a rolling type one-way clutch, it has a simple and inexpensive configuration that effectively reduces rattle of handle 3. In addition, because second reverse prevention device 40 is a rolling type one-way clutch, there is no contact that would impair the operational feel when rotating handle 3.

[0054] Furthermore, the outer ring 42, roller 43, retainer 44, and lid 48 are configured as a single assembly, which facilitates the installation and removal of the second reverse prevention device 40. Furthermore, there is no need for highly accurate removal of backlash during manufacturing.

[0055] Furthermore, since the second reverse rotation prevention device 40 is fixed to the reel body 1 (fixed member 18), it is possible to appropriately reduce backlash while restricting reverse rotation of the drive gear shaft 2 and the handle 3.

[0056] Furthermore, the second reverse prevention device 40 is a rolling one-way clutch, and the inner ring 41 is a cylindrical member attached to the drive gear shaft 2, so that the use of a highly versatile part, a rolling one-way clutch, can inexpensively restrict reverse rotation of the drive gear shaft 2 and the handle 3 while effectively preventing rattling of the drive gear shaft 2 and the handle 3.

[0057] (Second embodiment) A fishing spinning reel according to a second embodiment will be described with reference to Figures 6 and 7. This embodiment differs from the first embodiment in that the handle 3 is equipped with a handle shaft 33 that is inserted into the hollow portion of the drive gear shaft 2A, and accordingly, the second reverse prevention device 40A is configured to be attached to an auxiliary shaft 35 that is inserted into the hollow portion of the drive gear shaft 2A. As shown in Figure 6, 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-handed, and as shown in Figure 7, it is inserted into the hollow portion from the left side of the drive gear shaft 2A when the handle is right-handed.

[0058] 6, 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 portion 33a connected to the handle 3, and a small-diameter insertion portion 33b that is continuous with the base portion 33a and has a smaller diameter than the base portion 33a, and is inserted into the hollow portion of the drive gear shaft 2.

[0059] The insertion portion 33b includes a first insertion portion 33b1 that continues to the right end of the base portion 33a, and a second insertion portion 33b2 that continues to the first insertion portion 33b1. In other words, the insertion portion 33b has a tapered shape in which the outer circumferential surface gradually narrows (has a smaller diameter) toward the tip.

[0060] The outer peripheral surface of the first insertion portion 33b1 is formed with a male thread that screws into the female thread on the large-diameter inner peripheral surface on the left opening side of the drive gear shaft 2A. On the other hand, the outer peripheral surface of the second insertion portion 33b2 is formed with a male thread that screws into the female thread on the small-diameter inner peripheral surface on the far right side of the drive gear shaft 2A (see FIG. 7). The male thread of the first insertion portion 33b1 is a reverse thread, which is opposite to a positive thread. The male thread of the second insertion portion 33b2 is a positive thread.

[0061] A stepped surface 36 that functions as an abutment portion is integrally formed at the boundary between the base 33a and the first insertion portion 33b1 of the handle shaft 33. The stepped surface 36 is formed by utilizing the difference in outer diameter between the base 33a and the first insertion portion 33b1, and is a ring-shaped flat surface that is perpendicular to the central axis O2. The stepped surface 36 faces the left end portion 23A (left end surface) of the drive gear shaft 2 and the left side surface of the inner ring of the left ball bearing 15, and is configured to abut against the left end portion 23A (left end surface) of the drive gear shaft 2 and the left side surface of the inner ring of the left ball bearing 15 during the process of tightening the handle shaft 33 to the drive gear shaft 2.

[0062] The auxiliary shaft 35 is a shaft that is attached to the hollow portion of the drive gear shaft 2A by screwing. As shown in Fig. 6, the auxiliary shaft 35 has a large-diameter base portion 35a and a small-diameter insertion portion 35b that is continuous with the base portion 35a and has a smaller diameter than the base portion 35a and is inserted into the hollow portion of the drive gear shaft 2A. A ring-shaped flange 35c that protrudes radially outward is formed at the left end of the base portion 35a. A protrusion 35a1 is formed at the right end of the base portion 35a to tighten the auxiliary shaft 35 when screwed.

[0063] The insertion portion 35b includes a first insertion portion 35b1 that continues to the left end of the base portion 35a, and a second insertion portion 35b2 that continues to the first insertion portion 35b1. In other words, the insertion portion 35b has a tapered shape in which the outer circumferential surface gradually narrows (has a smaller diameter) toward the tip.

[0064] The outer peripheral surface of the second insertion portion 35b2 is formed with a male thread that screws into the female thread on the small-diameter inner peripheral surface on the far right side of the drive gear shaft 2A. On the other hand, the outer peripheral surface of the first insertion portion 35b1 is formed with a male thread that screws into the female thread on the large-diameter inner peripheral surface on the left opening side of the drive gear shaft 2A. The male thread on the first insertion portion 35b1 is a reverse thread, which is opposite to the positive thread. The male thread on the second insertion portion 35b2 is a positive thread.

[0065] The left side surface of the flange 35c is a ring-shaped flat surface perpendicular to the central axis O2. The left side surface of the flange 35c faces the right end portion 24A (right end surface) of the drive gear shaft 2 and is configured to come into contact with the right end portion 24A (right end surface) of the drive gear shaft 2 during the process of tightening the handle shaft 33 to the drive gear shaft 2.

[0066] The second reverse prevention device 40A does not have the inner ring 41 (see FIG. 3A) described in the first embodiment, and is composed only of an assembly including an outer ring 42, roller 43, retainer 44, and cover 48. In other words, the second reverse prevention device 40A is configured so that the roller 43 directly contacts the outer peripheral surface of the base 35a of the auxiliary shaft 35, thereby restricting reverse rotation of the drive gear shaft 2A and the handle 3 via the auxiliary shaft 35.

[0067] Next, the procedure for installing the second reverse prevention device 40A will be described. When using the left-hand drive as shown in Figure 6, the second reverse prevention device 40A is installed via the auxiliary shaft 35 attached to the right side of the drive gear shaft 2A. When installing the second reverse prevention device 40A, first, insert the auxiliary shaft 35 into the hollow portion from the right side of the drive gear shaft 2A and screw it in.

[0068] Thereafter, the outer ring 42, roller 43, retainer 44, and lid 48 configured as an assembly are attached between the base 35a and the fixed member 18. In this case, while adjusting the orientation of the assembly, the protruding portion 42a of the outer ring 42 of the assembly is aligned with the recessed portion 18d of the fixed portion 18c of the fixed member 18, and the assembly is inserted inside the fixed portion 18c.

[0069] Thereafter, the cap 17 is screwed onto the fixing portion 18c of the fixing member 18. As a result, the second reverse prevention device 40A is attached to the right side of the drive gear shaft 2.

[0070] Next, the procedure for installing the second reverse prevention device 40A when the handle is right-hand will be described. When the handle is right-hand, the second reverse prevention device 40A is installed on the left side of the drive gear shaft 2 via the auxiliary shaft 35, as shown in Figure 7. In this case as well, the auxiliary shaft 35 is attached to the left side of the drive gear shaft 2A, and then the assembly is attached. When attaching the assembly, the protruding portion 42a of the outer ring 42 of the assembly is aligned with the recessed portion 13b of the cover member 13, and the assembly is inserted inside the tip of the cover member 13.

[0071] Thereafter, the cap 17 is screwed onto the cover member 13. As a result, the second reverse prevention device 40A is attached to the left side of the drive gear shaft 2.

[0072] According to the present embodiment described above, the same effects as those of the first embodiment can be obtained. In addition, in this embodiment, the second reverse prevention device 40A does not include the inner ring 41, which is a relatively small part as described in the first embodiment, and therefore the second reverse prevention device 40A can be easily attached and detached.

[0073] 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, the second reverse prevention devices 40, 40A are attached to the left and right ends of the drive gear shaft 2 and the auxiliary shaft 35, but this is not limitative. As shown in the first and second modified examples in FIGS. 8 and 9, the second reverse prevention devices 45, 46 may be provided at other locations on the drive gear shaft 2.

[0074] In the first modified example shown in FIG. 8, a second reverse prevention device 45 is disposed in the space to the left of the ball bearing 16, which is in the vicinity of the right-side ball bearing 16. The second reverse prevention device 45 is a rolling one-way clutch. The second reverse prevention device 45 is interposed between the body 10 and the drive gear shaft 2, and includes an outer ring 45b fixed to the body 10, a roller 45a disposed between the drive gear shaft 2 and the outer ring 45b, and a retainer 45c. As in the previous embodiments, the second reverse prevention device 45 prevents the drive gear shaft 2 and the handle 3 from rotating in the reverse direction. This effectively reduces backlash while preventing the drive gear shaft 2 and the handle 3 from rotating in the reverse direction.

[0075] In the second modified example shown in FIG. 9, a second reverse prevention device 46 is disposed in the space to the left of the ball bearing 15, which is adjacent to the left ball bearing 15. The second reverse prevention device 46 is a rolling one-way clutch. The second reverse prevention device 46 is interposed between the cover member 13 and the drive gear shaft 2, and includes an outer ring 46b fixed to the cover member 13, a roller 46a disposed between the cylindrical portion 21e of the drive gear 21 and the outer ring 46b, and a retainer 46c. As in the previous embodiments, the second reverse prevention device 46 prevents the drive gear shaft 2 and the handle 3 from rotating in the reverse direction. This configuration also effectively reduces backlash while preventing the drive gear shaft 2 and the handle 3 from rotating in the reverse direction.

[0076] In addition, in each of the above embodiments, a rolling type one-way clutch is used as the second reverse prevention device 40, 40A, but this is not limited to this, and various types of reverse prevention devices, such as a cam type or other types, can be used. [Explanation of symbols]
