Description

[Technical Field]

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

[0002] Conventionally, spinning fishing reels with a detachable handle attached to the reel body have been known (see, for example, Patent Document 1). The spinning fishing reel of Patent Document 1 has a handle attached by threading the handle shaft onto the drive gear shaft of the reel body, and is equipped with a ball bearing that rotatably supports the drive gear shaft and a cylindrical member attached to the end of the drive gear shaft. A seal member that contacts the reel body is attached to the outer periphery of the cylindrical member. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6949661 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a fishing spinning reel that uses a handle shaft mounting structure that uses threaded engagement, as disclosed in Patent Document 1, there is a risk that the drive gear shaft and the handle shaft may be fixed in a misaligned state due to looseness of the threads when they are threaded together. This necessitates high-precision manufacturing of each component. Furthermore, a design that takes misalignment into account requires a large clearance. Furthermore, in a structure in which a sealing member is attached to a cylindrical member, as in the fishing spinning reel of Patent Document 1, the amount of contact (overlap) of the sealing member with the reel body may not be consistent, potentially resulting in inconsistent waterproofing.

[0005] The present invention was created to solve these problems, and aims to provide a fishing spinning reel that can achieve centering of the drive gear shaft and the handle shaft with a simple structure and can effectively prevent problems caused by center misalignment. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a spinning reel for fishing in which a handle is detachably attached to a reel body, the reel body being provided with: Has a female thread A cylindrical drive gear shaft having a handle shaft insertion hole formed therein, and a drive gear shaft provided on the handle and inserted into the handle shaft insertion hole. The female thread is screwed into A male thread was formed A handle shaft having an insertion portion, and the handle shaft insertion hole On the inner peripheral surface of the The engagement receiving portion and the insertion portion On the outer circumferential surface of the is provided in the engagement receiving portion By engaging with the handle shaft, the handle shaft is centered relative to the handle shaft insertion hole. When the handle shaft is screwed onto the drive gear shaft, the engaging portion engages with the engagement receiving portion, so that the central axes of the drive gear shaft and the handle shaft coincide with each other. The engaging portions are provided on both the front and rear ends of the insertion portion, and the engaging receiving portions are provided on the inner side and opening side of the handle shaft insertion hole at positions corresponding to the engaging portions. To solve the above-mentioned problems, the present invention provides a fishing spinning reel having a handle detachably attached to a reel body, the fishing reel including: a cylindrical drive gear shaft provided in the reel body and having a handle shaft insertion hole with an internal thread; a handle shaft provided in the handle and having an insertion portion with an external thread that is inserted into the handle shaft insertion hole and threadedly engages with the internal thread; an engagement receiving portion provided on the inner peripheral surface of the handle shaft insertion hole at a position separate from the internal thread; and an engagement portion provided on the outer peripheral surface of the insertion portion at a position separate from the external thread and that engages with the engagement receiving portion to center the handle shaft with respect to the handle shaft insertion hole. When the handle shaft is threaded onto the drive gear shaft, the engagement portion engages with the engagement receiving portion, thereby aligning the central axes of the drive gear shaft and the handle shaft. The engagement portion is provided on the rear end of the insertion portion, and the engagement receiving portion is provided on the opening side of the handle shaft insertion hole at a position corresponding to the engagement portion.

[0007] The present invention In this fishing spinning reel, when the handle shaft is threaded onto the drive gear shaft, the engaging portion of the handle shaft engages with the engaging receiving portion of the drive gear shaft, resulting in the handle shaft being fixed in a centered state relative to the drive gear shaft. In other words, the centering of the drive gear shaft and the handle shaft is automatically achieved during the process of threading the handle shaft onto the drive gear shaft. Therefore, centering of the drive gear shaft and the handle shaft can be achieved with a simple configuration, and problems caused by misalignment can be effectively prevented. Furthermore, because the handle shaft is centered relative to the drive gear shaft, the reel body supporting the drive gear shaft and the handle shaft are also centered. This allows the center axis of the handle shaft to be optimally aligned with the handle rotation center position set in the reel body during design.

[0009] Also The engaging portion and the engaging receiving portion are easy to form, and the centering of the drive gear shaft and the handle shaft can be achieved with a simple configuration. Furthermore, the engaging portion and the engaging receiving portion can be formed simultaneously when the drive gear shaft and the handle shaft are processed and molded, which increases production efficiency.

[0010] It is also preferable that a seal member be provided on one of the reel body and the handle shaft, and abut against the other to seal the gap between the reel body and the handle shaft.

[0011] In this configuration, since a seal member is provided on at least one of the handle shaft and the reel body, the amount of contact (overlap) of the seal member with the other can be kept constant, thereby maintaining the waterproofing provided by the seal member in an optimal manner. Furthermore, since the amount of contact (overlap) of the seal member with the other side can be kept constant, it is possible to prevent the seal member from sliding against the other side due to excessive contact pressure being applied, thereby reducing the initial rotation force of the handle while maintaining waterproofing, thereby improving fishing operability. [Effects of the Invention]

[0012] According to the present invention, a fishing spinning reel can be obtained in which the drive gear shaft and the handle shaft can be centered with a simple structure and problems caused by misalignment can be suitably prevented. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] The fishing spinning reel 100 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 Figure 1, and "left and right" refer to the directions shown in Figure 2.

[0015] (First embodiment) First, the basic structure of a fishing spinning reel 100 will be described. As shown in FIG. 1, a fishing spinning reel 100 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.

[0016] 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 part 12a at their tips 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.

[0017] A drive shaft tube (not shown) and a spool shaft 8 (partially shown in FIG. 2) are attached to the reel unit 1 so as to protrude forward from the front of the body 10. A rotor 4 is attached to the front end of the drive shaft tube. A spool 5 is attached to the front end of the spool shaft 8.

[0018] 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.

[0019] 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 and spool shaft 8 in conjunction with the operation of the handle 3. As shown in Figure 2, the drive gear shaft 2 is equipped with 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 via left and right ball bearings 15, 16. A handle shaft 31 provided on the handle 3 is threadedly attached to the drive gear shaft 2. This allows the handle 3 and the drive gear shaft 2 to rotate integrally. Details of the drive gear shaft 2 and the handle 3 will be described later.

[0020] 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, and includes a guide groove 61a that opens to the right. The interlocking gear 62 is supported by a support member 63 provided on the right side wall 10a 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.

[0021] 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.

[0022] Next, the drive gear shaft 2, the handle 3 and the connecting structure therebetween will be described in detail. As shown in Figure 2, the drive gear shaft 2 is generally cylindrical, has a stepped circular outer periphery along the central axis O1, and handle shaft insertion holes 23, 23 that open on both sides. The left handle shaft insertion hole 23 allows the handle 3 to be attached to the left side, and the right handle shaft insertion hole 23 allows the handle 3 to be attached to the right side (see Figure 4). The left and right handle shaft insertion holes 23, 23 communicate at the center of the drive gear shaft 2 in the axial direction.

[0023] The left and right handle shaft insertion holes 23 each have a large-diameter inner circumferential surface 23a formed on the opening side and a small-diameter inner circumferential surface 23b formed on the rear side of the large-diameter inner circumferential surface 23a and having a smaller diameter than the large-diameter inner circumferential surface 23a. Of these, the left large-diameter inner circumferential surface 23a and the right small-diameter inner circumferential surface 23b are each formed with an internal thread for threadingly engaging the handle shaft 31. The internal thread of the left large-diameter inner circumferential surface 23a is a reverse thread, which is opposite to a positive thread. On the other hand, the internal thread of the right small-diameter inner circumferential surface 23b is a positive thread.

[0024] A wall portion 28 that protrudes radially inward is formed in the axial center of the drive gear shaft 2. The wall portion 28 has an annular shape centered on the central axis O1. A circular communication hole 28a is formed in the radial center of the wall portion 28. Left and right side surfaces 28c, 28c of the wall portion 28 are flat surfaces that are perpendicular to the central axis O1.

[0025] As shown in FIGS. 3 and 4, tip portion housing inner peripheral surfaces 23c, 23c that are continuous with the small-diameter inner peripheral surfaces 23b, 23b are formed on both the left and right sides of the wall portion 28. Each tip portion housing inner peripheral surface 23c functions as an engagement receiving portion for centering the handle shaft 31. Each tip portion housing inner peripheral surface 23c, 23c has an even smaller diameter than the small-diameter inner peripheral surfaces 23b, 23b. A tip portion 34c (described later) of the handle shaft 31 is inserted into each tip portion housing inner peripheral surface 23c, 23c during the process of threading the handle shaft 31 into the drive gear shaft 2. The left and right side surfaces 28c, 28c of the wall portion 28 function as abutment surfaces against which a tip surface 34d of the tip portion 34c of the handle shaft 31 abuts, but the wall portion 28 itself is not necessarily provided.

[0026] A drive gear 21 is integrally formed on the outer circumferential surface of the drive gear shaft 2 at a position offset to the left from the center in the left-right direction. A gear 22 is also integrally formed on the drive gear shaft 2 at a position offset to the right from the center in the left-right direction. The drive gear shaft 2 is made of an aluminum alloy. In a fishing spinning reel 100 that is designed for high-load winding operations in which fishing line is wound under high loads (hereinafter referred to as a "high-load fishing spinning reel"), the drive gear shaft 2 may be made of, for example, stainless steel or steel instead of an aluminum alloy.

[0027] Next, with reference to FIG. 3, the connecting structure on the left side of the drive gear shaft 2 will be described in detail. The left outer peripheral surface of the drive gear shaft 2 is formed with a first outer peripheral portion 24 that continues to the left side of the drive gear 21, and a second outer peripheral portion 25 that continues to the left side of the first outer peripheral portion 24 and has a smaller diameter than the first outer peripheral portion 24. A ring-shaped stepped surface 25a that is perpendicular to the central axis O1 is formed between the first outer peripheral portion 24 and the second outer peripheral portion 25. The outer peripheral surface of the second outer peripheral portion 25 functions as a seat surface onto which the left ball bearing 15 is fitted. The stepped surface 25a also functions as a positioning surface that positions the right side surface of the inner ring 15a of the left ball bearing 15 via an annular washer 21a. The outer ring 15b of the left ball bearing 15 is fitted into the circular inner peripheral surface of the cover member 13 centered on the central axis O1.

[0028] The left end 25e of the second outer peripheral portion 25 is formed to a size that protrudes leftward beyond the left side surface of the inner ring 15a of the left ball bearing 15, or is formed to a size that is flush with the left side surface of the inner ring 15a. A small diameter surface 25b that is smaller in diameter than the second outer peripheral portion 25 is formed on the outer peripheral surface at the left end of the second outer peripheral portion 25. As a result, the outer diameter of the left end 25e of the drive gear shaft 2 is smaller than the inner diameter of the left ball bearing 15, forming a gap. The left and right ball bearings 15 and 16 are made of stainless steel.

[0029] Next, with reference to FIG. 4, the connecting structure on the right side of the drive gear shaft 2 will be described in detail. A third outer peripheral portion 26 is formed on the right outer peripheral surface of the drive gear shaft 2, continuing to the right side of the gear 22. A positioning protrusion 27 that protrudes radially outward is formed on the outer peripheral surface of the third outer peripheral portion 26. To the right of the positioning protrusion 27, the outer peripheral surface of the third outer peripheral portion 26 functions as a seat surface onto which the right ball bearing 16 is fitted. In addition, a right side surface 27a of the positioning protrusion 27 functions as a positioning surface for positioning the left side surface of the inner ring 16a of the right ball bearing 16. The outer ring 16b of the right ball bearing 16 is held in place by a retaining ring 10c on the inner surface of the right side wall 10a of the reel body 1. A cover member 17 is attached to the right side wall 10a (see FIG. 2).

[0030] The right end 26e of the third outer peripheral portion 26 is formed to a size that protrudes rightward beyond the right side surface of the inner ring 16a of the right ball bearing 16, or is formed to a size that is flush with the right side surface of the inner ring 16a. A stepped surface 26b is formed on the outer peripheral surface at the right end of the third outer peripheral portion 26. As a result, the outer diameter of the right end 26e is smaller than the inner diameter of the right ball bearing 16.

[0031] Next, we will explain the handle 3. As shown in Figure 2, the handle 3 includes an arm portion 32 and a handle shaft 31 that is connected to the arm portion 32 and has a stepped circular outer periphery along the central axis O1. A cover member 3a is attached to the connecting portion between the arm portion 32 and the handle shaft 31.

[0032] The handle shaft 31 has a large-diameter base portion 33 connected to the arm portion 32, and a small-diameter insertion portion 34 that is continuous with the base portion 33 and has a smaller diameter than the base portion 33, and is inserted into the handle shaft insertion hole 23 of the drive gear shaft 2.

[0033] The base 33 has a generally cylindrical shape with a bottom and an opening on the arm 32 side, and is hollow inside. A circumferential groove 33a with a concave cross section is formed on the outer circumferential surface of the base 33. A rubber-based annular seal member 40 is fitted into the circumferential groove 33a. The seal member 40 has an annular lip portion 41 whose diameter increases from the radially inner side to the radially outer side. An outer edge portion 42 of the lip portion 41 abuts against the inner circumferential edge portion 13c of the opening 13b of the lid member 13. The seal member 40 seals the gap between the base 33 (handle 3) and the lid member 13 (reel body 1 side member).

[0034] The insertion portion 34 is approximately cylindrical and has a first insertion portion 34a that is continuous with the bottom of the base portion 33, a second insertion portion 34b that is continuous with the first insertion portion 34a, and a tip portion 34c that is continuous with the second insertion portion 34b.

[0035] The first insertion portion 34a has an outer peripheral surface with a smaller diameter than the base portion 33. The second insertion portion 34b has an outer peripheral surface with a smaller diameter than the first insertion portion 34a. The outer peripheral surface of the first insertion portion 34a is formed with a male thread that screws into the female thread on the large-diameter inner peripheral surface 23a on the left side of the drive gear shaft 2. On the other hand, the outer peripheral surface of the second insertion portion 34b is formed with a male thread that screws into the female thread on the small-diameter inner peripheral surface 23b on the right side of the drive gear shaft 2. The male thread on the first insertion portion 34a is a reverse thread that is opposite to the positive thread. The male thread on the second insertion portion 34b is a positive thread.

[0036] A stepped surface 36 that functions as an abutment portion is integrally formed at the boundary between the base 33 and the first insertion portion 34a of the handle shaft 31. As shown in Fig. 3, the stepped surface 36 is formed by utilizing the difference in outer diameter between the base 33 and the first insertion portion 34a, and is a ring-shaped flat surface that is perpendicular to the central axis O1. The stepped surface 36 faces the left end 25e (left end face) of the second outer peripheral portion 25 and the left side surface of the inner ring 15a of the left ball bearing 15, and is configured to abut against the left end 25e of the second outer peripheral portion 25 and the left side surface of the inner ring 15a during the process of tightening the handle shaft 31 to the drive gear shaft 2.

[0037] In this embodiment, the step surface 36 is set to abut against the left side surface of the inner ring 15a at the same time that the step surface 36 abuts against the left end 25e of the second outer peripheral portion 25. However, the abutment of the step surface 36 is not limited to this, and the step surface 36 may be configured so that it abuts against one of the left end portion 25e of the second outer peripheral portion 25 and the left side surface of the inner ring 15a, and then the step surface 36 abuts against the other.

[0038] The tip portion 34c has a smaller diameter than the second insertion portion 34b and has an outer diameter that allows it to be inserted inside the tip portion housing inner circumferential surface 23c of the drive gear shaft 2. The tip portion 34c functions as an engagement portion for centering the handle shaft 31 with respect to the drive gear shaft 2. The tip portion 34c is inserted inside the tip portion housing inner circumferential surface 23c of the drive gear shaft 2 during the process of threading the handle shaft 31 onto the drive gear shaft 2. This insertion causes the center axes O1 of the drive gear shaft 2 and the handle shaft 31 to coincide.

[0039] A tip surface 34d of the tip portion 34c is formed as a flat surface perpendicular to the central axis O1. The tip surface 34d is adapted to come into contact with (be brought into contact with) the side surface 28c of the wall portion 28 when the handle shaft 31 is tightened.

[0040] According to the fishing spinning reel 100 of the present embodiment described above, when the handle shaft 31 is threaded onto the drive gear shaft 2, the tip end 34c, which is the engagement portion of the handle shaft 31, engages with the tip end housing inner circumferential surface 23c, which is the engagement receiving portion of the drive gear shaft 2. As a result, the handle shaft 31 is fixed in a centered state relative to the drive gear shaft 2. In other words, centering of the drive gear shaft 2 and the handle shaft 31 is automatically performed during the process of threading the drive gear shaft 2. Therefore, centering of the drive gear shaft 2 and the handle shaft 31 can be achieved with a simple configuration, and problems caused by misalignment can be preferably prevented. Furthermore, since the handle shaft 31 is centered relative to the drive gear shaft 2, the reel body 1, which supports the drive gear shaft 2, and the handle shaft 31 (handle 3) are also centered. This allows the center axis O1 of the handle shaft 31 to be preferably aligned with the rotation center position of the handle 3, which was set for the reel body 1 during design.

[0041] Furthermore, a tip portion 34c is provided at the tip end of the handle shaft 31, and a corresponding tip portion accommodating inner peripheral surface 23c is provided at the back side of the handle shaft insertion hole 23 of the drive gear shaft 2. Therefore, the engaging portion and the engaging receiving portion are easily formed, and the centering of the drive gear shaft 2 and the handle shaft 31 can be achieved with a simple configuration. Furthermore, the engaging portion and the engaging receiving portion can be formed simultaneously when the drive gear shaft 2 and the handle shaft 31 are processed and molded, resulting in high production efficiency.

[0042] Furthermore, since the seal member 40 is provided on the handle shaft 31 that is centered relative to the reel body 1, the amount of contact (overlap) of the lip portion 41 of the seal member 40 with the cover member 13 (the member on the reel body 1 side) can be kept constant. Therefore, the waterproofing provided by the seal member 40 can be maintained in an optimal manner. Furthermore, since the amount of contact (overlap) of the seal member 40 with the cover member 13 (the member on the reel body 1 side) can be kept constant, it is possible to prevent the seal member 40 from sliding against the cover member 13 (the member on the reel body 1 side) due to the application of more contact pressure than necessary, thereby reducing the initial rotational force of the handle 3 while maintaining waterproofing, thereby improving fishing operability.

[0043] (Second embodiment) A fishing spinning reel according to a second embodiment of the present invention will be described with reference to Figures 5 and 6. This embodiment differs from the first embodiment in that rear end housing inner peripheral surfaces 25f, 26f that function as engagement receiving portions are provided at the left and right openings of the drive gear shaft 2, and a rear end 39 that functions as an engagement portion is provided on the rear end side of the insertion portion 34 of the handle shaft 31.

[0044] As shown in FIG. 5, the rear end housing inner peripheral surface 25f on the left opening side of the drive gear shaft 2 is formed contiguous with the large-diameter inner peripheral surface 23a inside the opening of the left end 25e. Meanwhile, as shown in FIG. 6, the rear end housing inner peripheral surface 26f on the right opening side of the drive gear shaft 2 is formed contiguous with the large-diameter inner peripheral surface 23a inside the opening of the right end 26e. Each rear end housing inner peripheral surface 25f, 26f functions as an engagement receiving portion for centering the handle shaft 31. As shown in FIGS. 5 and 6, each rear end housing inner peripheral surface 25f, 26f has a larger diameter than the large-diameter inner peripheral surfaces 23a, 23a. The rear end 39 of the insertion portion 34 of the handle shaft 31 is inserted into each rear end housing inner peripheral surface 25f, 26f during the process of threading the handle shaft 31 into the drive gear shaft 2.

[0045] The rear end 39 is located at the corner between the stepped surface 36 of the handle shaft 31 and the first insertion portion 34a. The rear end 39 has an annular shape centered on the central axis O1 and has an outer diameter that allows it to be inserted into the rear end housing inner peripheral surfaces 25f, 26f of the drive gear shaft 2. The outer peripheral surface of the rear end 39 is parallel to the central axis O1. Furthermore, the side surface that is continuous with the outer peripheral surface of the rear end 39 is a flat surface that is perpendicular to the central axis O1. Such rear end 39 functions as an engaging portion for centering the handle shaft 31 relative to the drive gear shaft 2, and is inserted into the rear end housing inner peripheral surfaces 25f, 26f of the drive gear shaft 2 during the process of threading the handle shaft 31 onto the drive gear shaft 2. This insertion causes the central axes O1 of the drive gear shaft 2 and the handle shaft 31 to coincide with each other.

[0046] According to the fishing spinning reel 100 of this embodiment described above, the same effects as those of the first embodiment can be obtained. Furthermore, a rear end portion 39 serving as an engaging portion is provided on the rear end side of the handle shaft 31, and corresponding rear end portion accommodating inner peripheral surfaces 25f, 26f serving as engaging receiving portions are provided on the opening sides of the handle shaft insertion holes 23, 23 of the drive gear shaft 2. Therefore, the engaging portion and the engaging receiving portion are easy to form, and the centering of the drive gear shaft 2 and the handle shaft 31 can be achieved with a simple configuration. Furthermore, the engaging portion and the engaging receiving portion can be formed simultaneously when the drive gear shaft 2 and the handle shaft 31 are processed and molded, resulting in high production efficiency.

[0047] Similarly, in this embodiment, the amount of contact (overlap) of the seal member 40 with the cover member 13 (the reel body 1 side member) can be kept constant. Therefore, the waterproofing provided by the seal member 40 can be maintained in an appropriate manner. Furthermore, the initial rotational force of the handle 3 can be reduced while maintaining waterproofing, improving fishing operability.

[0048] Although the embodiments of the present invention have been described above, the present invention is not limited to the examples shown in the embodiments. 7, a seal member 45 may be placed in the opening 13b of the cover member 13 to seal the gap between the cover member 13 (the member on the reel body 1 side) and the base 33 (the handle 3). The seal member 45 includes a peripheral portion 46 that fits into a circumferential groove 13e with a concave cross section formed on the outer periphery of the opening 13b of the cover member 13, and an annular lip portion 47 whose diameter decreases radially outward from the end of the peripheral portion 46. An inner edge portion 48 of the lip portion 47 abuts against the outer periphery of the base 33 of the handle shaft 31.

[0049] Even in this configuration, the amount of contact (overlap amount) of the lip portion 47 of the seal member 45 with the handle shaft 31 (base portion 33) can be kept constant, thereby making it possible to suitably maintain the waterproofing provided by the seal member 45. Furthermore, since the amount of contact (overlap) of the seal member 45 with the handle shaft 31 (base 33) can be kept constant, it is possible to prevent the seal member 45 from sliding against the handle shaft 31 (base 33) due to the application of more contact pressure than necessary, thereby reducing the initial rotational force of the handle 3 while maintaining waterproofing, thereby improving fishing operability.

[0050] Furthermore, in the first embodiment, the tip portion 34c of the handle shaft 31 is shown to have an approximately cylindrical shape, but this is not limited to this, and any shape may be used as long as it can be inserted into the inside of the tip portion accommodating inner surface 23c to achieve centering. For example, various shapes may be adopted, such as a shape that is inscribed in the tip portion accommodating inner surface 23c at multiple points.

[0051] Furthermore, in the second embodiment, the rear end portion 39 of the handle shaft 31 is shown to have an approximately cylindrical shape, but this is not limited to this, and any shape may be used as long as it can be inserted into the inside of the rear end portion accommodating inner surfaces 25f, 26f to achieve centering. For example, various shapes may be adopted, such as a shape that is inscribed in the rear end portion accommodating inner surfaces 25f, 26f at multiple points.

[0052] In addition, in the first and second embodiments, an engagement portion is provided on either the tip or rear end side of the insertion portion 34, and an engagement receiving portion is provided on either the back side or opening side of the corresponding handle shaft insertion hole 23, but this is not limited to this and the engagement receiving portion may be provided on both sides.

[0053] Furthermore, the engaging portion and the engaging receiving portion are not limited to the tip and rear end sides of the insertion portion 34 and the inner and opening sides of the handle shaft insertion hole 23, but may be provided at other engaging positions.

[0054] Furthermore, in each of the above embodiments, a fishing spinning reel 100 in which the cover member 13 is screwed into the side opening 11 has been described, but this is not limited to this, and the present invention can also be suitably applied to a fishing spinning reel in which the cover member is fixed to the reel body using screws or other fixing means.
