Description
TECHNICAL FIELD
[0001] The present application relates to a fishing spinning reel. BACKGROUND
[0002] In the past, a fishing spinning reel configured to attach and detach a handle to / from a reel body is known (see, for example, Patent Literature 1). Patent Literature 1 is configured to attach the handle by screwing a handle shaft to a drive gear shaft of the reel body, and has a cylindrical member provided between the drive gear shaft and the handle shaft and a ball bearing rotatably supporting the drive gear shaft. The drive gear shaft has a drive gear, and is rotatably supported by the ball bearing.
[0003] The portion of the cylindrical member of Patent Literature 1 that opposes the end portion of the drive gear shaft has a gap with respect to the end portion of the drive gear shaft. On the other hand, the cylindrical member is configured to abut against and be deformed by the ball bearing that supports the drive gear shaft. Thus, Patent Literature 1 can prevent excessive application of the thrust force of the handle shaft due to screwing to the drive gear shaft.
[0004] Patent Literature
[0005] Patent Literature 1: Japanese Patent Application Publication No. 2017-108717 SUMMARY
[0006] Since Patent Literature 1 is configured to prevent the load acting on the drive gear shaft by the cylindrical member provided between the drive gear shaft and the handle shaft, there is a problem in that the structure of the connection between the drive gear shaft and the handle shaft is complicated, and it is necessary to manufacture each part with high dimensional accuracy, which leads to an increase in cost.
[0007] The present application has been made to solve the above problems, and an object thereof is to provide a fishing spinning reel capable of simplifying the structure of the connection between the drive gear shaft and the handle shaft and reducing the cost.
[0008] To solve the above problems, the present application is a fishing spinning reel configured to attach and detach a handle to / from a reel body. The fishing spinning reel includes a drive gear shaft provided on the reel body, a ball bearing fitted on the drive gear shaft to rotatably support the drive gear shaft, and a handle shaft provided on the handle and screwed to the drive gear shaft. An abutting portion that abuts against an inner ring of the ball bearing by screwing to the drive gear shaft is integrally provided on the handle shaft.
[0009] On the fishing spinning reel, when the handle shaft is screwed with the drive gear shaft, the abutting portion of the handle shaft abuts against the inner ring of the ball bearing, and the handle shaft is fixed to the drive gear shaft. That is, the handle shaft can be fixed to the drive gear shaft in a state where the pressing force of the screwing of the handle shaft is suppressed by the abutting of the abutting portion against the inner ring of the ball bearing (i.e., a state where the abutting portion has a stop function against the inner ring of the ball bearing). Thus, the end portion of the drive gear can be prevented from being bent due to the screwing of the handle shaft.
[0010] Further, since the abutting portion is provided integrally on the handle shaft, a cylindrical member as in the related art does not need to be inserted between the drive gear shaft and the handle shaft. Thus, the connection structure of the drive gear shaft and the handle shaft can be simplified, and cost reduction can be achieved.
[0011] Further, since the abutting portion is provided integrally on the handle shaft, the handle shaft can be manufactured with high dimensional accuracy, and the strength is increased as compared with the case where the cylindrical member as in the related art is used.
[0012] Further, even if the ball bearing is deformed due to the excessive screwing of the handle shaft, only the ball bearing, which is cheaper than the drive gear shaft, needs to be replaced, so maintenance is facilitated and repair costs can be reduced.
[0013] Further, it is preferable that the handle shaft have a base portion with a large diameter and an insertion portion with a smaller diameter than the base portion and inserted into the drive gear shaft. In this case, it is preferable that the abutting portion be provided on a boundary portion between the base portion and the insertion portion.
[0014] In this configuration, the abutting portion can be easily formed using the step portion of the base portion with a large diameter and the insertion portion with a small diameter, and the connection structure of the drive gear shaft and the handle shaft can be simplified.
[0015] Further, it is preferable that the raw material of the handle shaft be composed of a raw material with higher strength than the raw material of the ball bearing.
[0016] In this configuration, the ball bearing, which is cheaper than the drive gear shaft, can be deformed when the excessive screwing of the handle shaft occurs. Thus, maintenance is facilitated and repair costs can be reduced.
[0017] Further, it is preferable that the outer diameter of the end portion of the drive gear shaft be smaller than the inner diameter of the ball bearing.
[0018] In this configuration, a space for escaping the portion of the bending deformation can be formed between the end portion of the drive gear shaft and the inner ring of the ball bearing. Thus, even if the bending occurs on the end portion of the drive gear shaft due to the excessive screwing of the handle shaft, the influence thereof can be accommodated in the space for the bending deformation. Thus, maintenance such as replacement of the ball bearing can be facilitated.
[0019] Further, it is preferable that the abutting portion have a portion opposite the ball bearing and a portion opposite the end of the drive gear shaft, and that flat surfaces be formed on both portions.
[0020] In this configuration, since the workability of the handle shaft is improved, cost reduction can be achieved.
[0021] Further, it is preferable that the abutting portion abut against both the inner ring of the ball bearing and the end surface of the drive gear shaft at the same time when the handle shaft is screwed to the drive gear shaft, or that the abutting portion abut against the inner ring of the ball bearing after abutting against the end of the drive gear shaft when the handle shaft is screwed to the drive gear shaft.
[0022] In the configuration in which the abutting portion abuts against both the inner ring of the ball bearing and the end of the drive gear shaft at the same time, the handle shaft can be fixed to the drive gear shaft in a state in which the pressing force of the screwing of the handle shaft to the drive gear shaft is suppressed by the abutting of the abutting portion against the inner ring of the ball bearing and the end of the drive gear shaft (i.e., in a state in which the abutting portion has a function of limiting the inner ring of the ball bearing). That is, the area of the portion that supports the shaft force of the screwing of the handle shaft can be increased, and thus strength improvement can be achieved.
[0023] Further, in the configuration in which the abutting portion abuts against the inner ring of the ball bearing after abutting against the end of the drive gear shaft, the abutting portion abuts against the inner ring of the ball bearing after the end of the drive gear shaft is bent by the abutting of the abutting portion. Thus, in this case as well, the portion that supports the shaft force of the screwing of the handle shaft can be increased in the end, and thus strength improvement can be achieved.
[0024] According to the present application, a fishing reel of the spinning type in which the linking structure of the drive gear shaft and the handle shaft can be simplified and cost reduction can be achieved can be obtained. BRIEF DESCRIPTION OF DRAWINGS

[0033] The spinning reel 100 for fishing according to various embodiments will be described with reference to the accompanying drawings. In the following description, "front and back" and "up and down" are used to refer to... Figure 1 Using the indicated direction as a reference, when referring to "left and right", it is based on... Figure 2 The direction shown is the reference.
[0034] (First Embodiment)
[0035] First, the basic structure of the fishing spinning reel 100 will be explained.
[0036] like Figure 1 As shown, the fishing spinning reel 100 includes: a reel body 1 with a handle 3; 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 drum 5 disposed on the front side of the rotor 4 and reciprocating in the front-back direction by the winding operation of the handle 3.
[0037] The reel body 1 includes: a main body 10 having a side opening 11 facing to the left; a foot 12 extending upward from the upper part of the main body 10 and having a rod mounting part 12a at the top for mounting onto a fishing rod; a cover part 13 that closes the side opening 11; and a protective cover 14 that is mounted on the rear of the main body 10.
[0038] On the reel body 1, a drive shaft cylinder (not shown) and a reel shaft 8 are mounted in such a way that they protrude forward from the front of the main body 10. Figure 2 (Partially shown in the diagram). A rotor 4 is mounted at the front end of the drive shaft cylinder. A drum 5 is mounted at the front end of the drum shaft 8.
[0039] like Figure 2As shown, the cover member 13 has a cylindrical insertion portion 13a inserted into the inside of the side opening portion 11. On the outer peripheral surface of the insertion portion 13a, an external thread portion is formed. The external thread portion is screwed with an internal thread portion formed on the inner peripheral surface of the side opening portion 11. By the screwing, the main body 10 and the cover member 13 become integrated.
[0040] In the main body 10, as a configuration for driving the drive shaft cylinder and the reel shaft 8 in conjunction with the operation of the handle 3, a drive gear shaft 2 extending in the left-right direction and a reel reciprocating movement device 60 are provided.
[0041] As shown, Figure 2 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 by left and right ball bearings 15, 16. The handle shaft 31 provided in the handle 3 is mounted on the drive gear shaft 2 by screwing. Thus, the handle 3 rotates integrally with the drive gear shaft 2. Details of the drive gear shaft 2 and the handle 3 will be described later.
[0042] The reel reciprocating movement device 60 has a slider 61 configured to move in the front-rear direction along a guide shaft (not shown) extending in the front-rear direction of the main body 10, and a linkage gear 62. The slider 61 is fixed to the rear end of the reel shaft 8 and has a guide groove 61a opening to the right. The linkage gear 62 is supported on a support member 63 provided on the right side wall 10a of the main body 10, 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.
[0043] By the above, when the gear shaft 2 and the gear 22 rotate by the winding operation of the handle 3, the linkage gear 62 rotates, and this rotational movement is converted into front-rear movement of the slider 61 by the eccentric protrusion 62a and the guide groove 61a. Thus, the reel shaft 8 (reel 5) moves back and forth in the front-rear direction.
[0044] Next, the drive gear shaft 2, the handle 3, and their connection structure will be described in detail.
[0045] As shown, Figure 2 the drive gear shaft 2 is substantially cylindrical and has a stepped circular outer peripheral surface along the center axis O1 and screw holes 23, 23 opening to the left and right. By the left screw hole 23, the handle 3 can be mounted to the left, and by the right screw hole 23, the handle 3 can be mounted to the right (see Figure 5 ).
[0046] Each of the screw holes 23 has a large-diameter inner peripheral surface 23a formed on the opening side and a small-diameter inner peripheral surface 23b formed on the inner side of the large-diameter inner peripheral surface 23a and smaller in diameter than the large-diameter inner peripheral surface 23a. Of these, on the left-side large-diameter inner peripheral surface 23a and the right-side small-diameter inner peripheral surface 23b, respectively, an internal thread for screwing the handle shaft 31 is formed. The internal thread of the left-side large-diameter inner peripheral surface 23a is a reverse thread opposite to a normal thread. On the other hand, the internal thread of the right-side small-diameter inner peripheral surface 23b is a normal thread.
[0047] On the outer peripheral surface of the drive gear shaft 2, at a position deviated to the left from the center portion in the left-right direction, the drive gear 21 is integrally formed. Further, on the outer peripheral surface of the drive gear shaft 2, at a position deviated to the right from the center portion in the left-right direction, the gear 22 is integrally formed. The drive gear shaft 2 and the drive gear 21 are formed of an aluminum alloy. Alternatively, on a fishing spinning reel (hereinafter referred to as "fishing spinning reel for high load") 100 corresponding to a high-load winding operation in which the fishing line is wound in a state in which a high load is applied, for example, the drive gear shaft 2 can be formed of stainless steel or steel instead of the aluminum alloy.
[0048] Next, the structure of the fishing spinning reel 1 will be described with reference to the drawings. Figure 3 The connecting structure of the left side of the drive gear shaft 2 will be described in detail.
[0049] On the left-side outer peripheral surface of the drive gear shaft 2, a first outer peripheral portion 24 connected to the left side of the drive gear 21 and a second outer peripheral portion 25 connected to the left side of the first outer peripheral portion 24 and smaller in diameter than the first outer peripheral portion 24 are formed. Between the first outer peripheral portion 24 and the second outer peripheral portion 25, an annular step surface 25a orthogonal to the center axis O1 (see the same hereinafter) is formed. The outer peripheral surface of the second outer peripheral portion 25 functions as a contact surface for fitting the left ball bearing 15 thereon. Further, the step surface 25a functions as a positioning surface for positioning the right side surface of the inner ring 15a of the left ball bearing 15 by the annular gasket 24a. Figure 2
[0050] Further, 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 center axis O1.
[0051] The left end portion of the second outer peripheral portion 25 has a dimension protruding to the left side more than the left side surface of the inner ring 15a of the left ball bearing 15. The left end outer peripheral surface 25b of the second outer peripheral portion 25 is a tapered inclined surface narrowing toward the left end, and is apart from the inner ring 15a of the left ball bearing 15. Thus, the outer diameter of the left end portion of the drive gear shaft 2 is smaller than the inner diameter of the left ball bearing 15.
[0052] Here, the left and right ball bearings 15, 16 are formed of stainless steel.
[0053] Next, the right side of the drive gear shaft 2 will be described in detail. Figure 4
[0054] On the right side outer peripheral surface of the drive gear shaft 2, a third outer peripheral portion 26 is formed which is connected to the right side of the gear 22. On the outer peripheral surface of the third outer peripheral portion 26, a positioning protrusion 27 is formed which protrudes to the radial direction outer side. The outer peripheral surface of the third outer peripheral portion 26 on the right side of the positioning protrusion 27 functions as a contact surface for the outer ring 16b of the right ball bearing 16. Further, the right side surface 27a of the positioning protrusion 27 functions as a positioning surface for the left side surface of the inner ring 16a of the right ball bearing 16.
[0055] Further, on the right side wall 10a of the line winder body 1, the outer ring 16b of the right ball bearing 16 is inserted to the left side of the annular inner peripheral portion 10b centered on the center axis Ol by the washer 10c. Further, on the right side wall 10a, the cover member 17 is installed (refer to Figure 2 ).
[0056] The right end portion of the third outer peripheral portion 26 has a protruding dimension to the right side which is larger than the right side surface of the inner ring 16a of the right ball bearing 16. Like the aforementioned left end outer peripheral surface 25b, the right end outer peripheral surface 26b of the third outer peripheral portion 26 is a tapered inclined surface which narrows toward the right end, and is separated from the inner ring 16a of the right ball bearing 16. Due to this, the outer diameter of the right end portion of the third outer peripheral portion 26 is smaller than the inner diameter of the right ball bearing 16.
[0057] Next, the handle 3 will be described. As shown in Figure 2 , the handle 3 is provided with an arm portion 32, and a handle shaft 31 which is connected to the arm portion 32 and is provided with a stepped circular outer peripheral surface along the center axis Ol. On the connection portion of the arm portion 32 and the handle shaft 31, the cover member 3a is installed.
[0058] The handle shaft 31 is provided with a large diameter base portion 33 which is connected to the arm portion 32, and a small diameter insertion portion 34 which is connected to the base portion 33, is formed to be smaller in diameter than the base portion 33, and is inserted into the screw hole 23 of the drive gear shaft 2. The raw material of the handle shaft 31 is formed from a raw material which is stronger than the raw material of the drive gear shaft 2, such as stainless steel or steel. Further, the raw material of the handle shaft 31 can also use other high strength raw materials such as titanium alloy or aluminum alloy.
[0059] Here, the strength relationship of the raw materials of the drive gear shaft 2, ball bearings 15 and 16, and handle shaft 31 is: handle shaft 31 > ball bearings 15 and 16 > drive gear shaft 2. However, in a high-load fishing spinning reel 100, their strength relationship can be set to handle shaft 31 ≒ drive gear shaft 2 > ball bearings 15 and 16. Alternatively, another strength relationship can be set to ball bearings 15 and 16 > handle shaft 31 ≒ drive gear shaft 2. Thus, by setting the strength of ball bearings 15 and 16 to be higher than that of handle shaft 31 or drive gear shaft 2, damage to ball bearings 15 and 16 can be suppressed, and the rotational feel of the handle 3 can be maintained well for a long time. In particular, in a high-load fishing spinning reel 100, since the load acting on the drive gear shaft 2 is high, it is preferable to increase the strength of ball bearings 15 and 16.
[0060] The base 33 is a generally bottomed cylindrical shape with an opening on the side of the arm 32, and its inner side is hollow. The insertion part 34 is generally cylindrical and has a first insertion part 34a connected to the bottom of the base 33 and a second insertion part 34b connected to the first insertion part 34a. The first insertion part 34a has an outer peripheral surface with a smaller diameter than the base 33. An abutment part 36 is integrally provided at the boundary between the base 33 and the first insertion part 34a.
[0061] like Figure 3 As shown, the abutment portion 36 includes a protrusion 36a and an abutment surface 36b. The protrusion 36a is annular and protrudes to the right from the outer periphery of the base 33. The cross-section of the protrusion 36a is approximately rectangular. The protrusion 36a faces the left side of the inner ring 15a of the left ball bearing 15 and is configured to abut against the left side of the inner ring 15a during the process of fastening the handle shaft 31 to the drive gear shaft 2.
[0062] The abutment surface 36b is connected to the radially inner side of the protrusion 36a and is an annular flat surface orthogonal to the central axis O1. The abutment surface 36b is opposite to the left end face of the second outer peripheral portion 25 of the drive gear shaft 2 and is configured to abut against the left end face of the second outer peripheral portion 25 during the process of fastening the handle shaft 31 to the drive gear shaft 2.
[0063] In this embodiment, when the protrusion 36a abuts against the left side of the inner ring 15a, the abutting surface 36b simultaneously abuts against the left end surface of the second outer peripheral portion 25.
[0064] That is, it is configured such that the protrusion 36a and the contact surface 36b of the contact portion 36 abut against the second outer peripheral portion 25 and the inner ring 15a on the side of the drive gear shaft 2.
[0065] A gap portion S1 is formed on the radially inner side of the protruding portion 36a. The gap portion S1 is divided by the radially inner circumferential surface of the protruding portion 36a, the abutting surface 36b, the left end circumferential surface 25b of the second outer circumferential portion 25, and the inner ring 15a of the left ball bearing 15, and has a substantially triangular cross section.
[0066] Although it is configured as described above in the present embodiment that the abutting surface 36b abuts against the left end surface of the second outer circumferential portion 25 at the same time as the protruding portion 36a abuts against the left side surface of the inner ring 15a at the time of coupling, the present application is not limited to this. For example, it can be configured that a gap is formed between the left end surface of the second outer circumferential portion 25 and the abutting surface 36b at the time when the protruding portion 36a abuts against the left side surface of the inner ring 15a. That is, it can be configured that the handle shaft 31 is fixed to the drive gear shaft 2 by pressing the inner ring 15a by the protruding portion 36a.
[0067] Further, it can be configured in the opposite manner to the above that the abutting surface 36b abuts against the left end surface of the second outer circumferential portion 25 first, and then the protruding portion 36a abuts against the left side surface of the inner ring 15a during the process of screwing the handle shaft 31 into the drive gear shaft 2.
[0068] In this case, since the abutting surface 36b abuts against the left end surface of the second outer circumferential portion 25 first during the process of screwing, the left end portion of the second outer circumferential portion 25 is actively buckling deformed by the abutment of the abutting portion 36 formed of a high-strength material, and the protruding portion 36a is pressed against the left side surface of the inner ring 15a. At this point, the gap portion S1 formed on the left end portion of the second outer circumferential portion 25 functions as a space for allowing the buckling-deformed portion to escape. That is, the protruding portion 36a can be pressed against the left side surface of the inner ring 15a while promoting appropriate buckling deformation of the left end portion of the second outer circumferential portion 25.
[0069] Figure 5 is an enlarged cross-sectional view showing the coupling structure of the drive gear shaft 2 and the handle shaft 31 at the right handle.
[0070] At the right handle, the second insertion portion 34b of the top end side of the handle shaft 31 is screwed into the small-diameter inner circumferential surface 23b on the inner side of the screw hole 23. The protruding portion 36a of the abutting portion 36 opposes the right side surface of the inner ring 16a of the right ball bearing 16, and abuts against the right side surface of the inner ring 16a during the process of fastening the handle shaft 31 to the drive gear shaft 2.
[0071] On the other hand, the abutting surface 36b opposes the right end surface of the third outer circumferential portion 26 of the drive gear shaft 2, and abuts against the right end surface of the third outer circumferential portion 26 during the process of fastening the handle shaft 31 to the drive gear shaft 2. At this point, it is also configured that the abutting surface 36b abuts against the right end surface of the third outer circumferential portion 26 at the same time as the protruding portion 36a abuts against the right side surface of the inner ring 16a at the time of coupling.
[0072] That is, the abutting portion 36 is configured so that the entire left side surface thereof abuts against the third outer peripheral portion 26 and the inner ring 16a on the side of the drive gear shaft 2.
[0073] In the right-hand handle, a gap portion S1 is also formed on the radially inner side of the protruding portion 36a. The gap portion S1 is divided by the radially inner peripheral surface of the protruding portion 36a, the abutting surface 36b, the right end outer peripheral surface 26b of the third outer peripheral portion 26, and the inner ring 16a of the right ball bearing 16, and has a substantially triangular cross section.
[0074] Further, although it is configured as described above that the abutting surface 36b abuts against the right end surface of the third outer peripheral portion 26 at the same time as the protruding portion 36a abuts against the right side surface of the inner ring 16a, the present application is not limited thereto. For example, it can be configured so that a gap is formed between the right end surface of the third outer peripheral portion 26 and the abutting surface 36b when the protruding portion 36a abuts against the right side surface of the inner ring 16a. That is, it can be configured so that the handle shaft 31 is mainly fixed to the drive gear shaft 2 by pressing the protruding portion 36a against the right side surface of the inner ring 16a.
[0075] Further, it can be configured so that the abutting surface 36b abuts against the right end surface of the third outer peripheral portion 26 first, and then the protruding portion 36a abuts against the right side surface of the inner ring 16a, in the process of screwing the handle shaft 31 into the drive gear shaft 2, contrary to the foregoing.
[0076] In this case, since the abutting surface 36b abuts against the right end surface of the third outer peripheral portion 26 first in the process of screwing, the right end portion of the third outer peripheral portion 26 is actively subjected to buckling deformation by the abutment of the abutting portion 36 composed of a high-strength material, and the protruding portion 36a is pressed against the left side surface of the inner ring 16a. At this time, the gap portion S1 formed on the right end portion of the third outer peripheral portion 26 functions as a space for escaping the buckling-deformed portion. That is, the protruding portion 36a can be pressed against the right side surface of the inner ring 16a while promoting appropriate buckling deformation of the right end portion of the third outer peripheral portion 26.
[0077] According to the present embodiment described above, for example, when the handle shaft 31 is screwed onto the drive gear shaft 2 in the left-hand handle, the abutting portion 36 (protruding portion 36a) of the handle shaft 31 approaches and abuts against the inner ring 15a of the left ball bearing 15, and the handle shaft 31 is fixed to the drive gear shaft 2. That is, the handle shaft 31 can be fixed to the drive gear shaft 2 in a state in which the screwing pressure of the handle shaft 31 is suppressed by the abutment of the abutting portion 36 against the inner ring 15a of the left ball bearing 15 (i.e., a state in which the abutting portion has a stop function against the inner ring of the ball bearing). Thus, it is possible to prevent the end portion of the drive gear shaft 2 from being buckled due to the screwing of the handle shaft 31.
[0078] Further, since the abutting portion 36 is provided integrally on the handle shaft 31, it is not necessary to insert the existing cylindrical member between the drive gear shaft 2 and the handle shaft 31. Thus, it is possible to simplify the connecting structure of the drive gear shaft 2 and the handle shaft 31, and to achieve cost reduction.
[0079] Further, since the abutting portion 36 is provided integrally on the handle shaft 31, it is possible to manufacture the handle shaft 31 with high dimensional accuracy, and the strength is increased compared with the case where the existing cylindrical member is used.
[0080] Further, since the abutting surface 36b abuts against the left end surface of the second outer peripheral portion 25 at the same time as the protruding portion 36a abuts against the left side surface of the inner ring 15a, it is possible to increase the area of the portion that supports the screwed shaft force of the handle shaft 31, and thus it is possible to achieve strength improvement.
[0081] Further, since the handle shaft 31 is made of a high-strength material that is stronger than the left ball bearing 15, when the protruding portion 36a abuts against the left side surface of the inner ring 15a, it is possible to obtain the following effect even if the left ball bearing 15 is deformed by being pressed by the protruding portion 36a due to excessive screwing of the handle shaft 31. That is, it is only necessary to replace the left ball bearing 15, which is cheaper than the drive gear shaft 2, and thus it is easy to maintain and it is possible to reduce repair costs.
[0082] Further, on the contrary, in the case where the abutting surface 36b abuts against the left end surface of the second outer peripheral portion 25 first, and then the protruding portion 36a abuts against the left side surface of the inner ring 15a, the abutting portion 36 abuts against the inner ring 15a after the left end portion of the second outer peripheral portion 25 is plastically deformed by abutting against the abutting portion 36. Thus, in this case, since it is also possible to finally increase the area of the portion that supports the screwed shaft force of the handle shaft 31, it is possible to achieve strength improvement.
[0083] The above-mentioned effect is also obtained when the handle shaft 31 is screwed to the right side of the drive gear shaft 2.
[0084] (Second Embodiment)
[0085] Reference Figure 6 A spinning-type fishing reel according to the second embodiment of the present application will be described. The present embodiment differs from the first embodiment in that the abutting portion 36A is formed by a flat surface.
[0086] The abutting portion 36A has an abutting surface 37 orthogonal to the center axis O1. The abutting surface 37 is formed as a flat surface at both a portion opposite to the left side surface of the inner ring 15a and a portion opposite to the left end surface of the second outer peripheral portion 25.
[0087] On the other hand, the left side surface of the inner ring 15a and the left end surface of the second outer peripheral portion 25 also become the same plane in a direction orthogonal to the center axis O1, and are set to be flat in correspondence with the abutting surface 37 of the abutting portion 36A.
[0088] Thus, in the process of screwing the handle shaft 31 into the drive gear shaft 2, the abutting surface 37 of the abutting portion 36A simultaneously abuts against the left side surface of the inner ring 15a and the left end surface of the second outer peripheral portion 25. This is also the same in the coupling structure when the right handle is used.
[0089] In addition, in the present embodiment, instead of the gap portion S1 described in the first embodiment, a gap portion S2 having a different shape is formed on the left end portion of the second outer peripheral portion 25. The gap portion S2 is a stepped surface in which the left end outer peripheral surface 25c of the second outer peripheral portion 25 is formed to have a small diameter.
[0090] According to the present embodiment described above, in addition to the same effects as those described in the first embodiment, since the abutting surface 37 having a flat surface is provided, the workability of the handle shaft 31 is improved. Thus, cost reduction can be achieved.
[0091] In addition, although in the present embodiment, the abutting surface 37 of the abutting portion 36A is set to simultaneously abut against the left side surface of the inner ring 15a and the left end surface of the second outer peripheral portion 25, it is not limited thereto. For example, it can be set such that a gap is formed between the left end surface of the second outer peripheral portion 25 and the abutting surface 37 when the abutting surface 37 abuts against the left side surface of the inner ring 15a. That is, it can be configured such that the handle shaft 31 is fixed to the drive gear shaft 2 by the pressing of the inner ring 15a by the abutting surface 37. In this case, since the abutting surface 37 is a flat surface, the workability of the handle shaft 31 can be improved and cost reduction can be achieved.
[0092] Further, even if it is assumed that the left ball bearing 15 is deformed by being pressed by the abutting portion 36A due to excessive screwing of the handle shaft 31, it is only necessary to replace the left ball bearing 15 which is less expensive than the drive gear shaft 2, and thus maintenance is facilitated and repair costs can be reduced.
[0093] Further, contrary thereto, it can be set such that the abutting surface 37 first abuts against the left end surface of the second outer peripheral portion 25, and then the abutting surface 37 abuts against the left side surface of the inner ring 15a. In this case, since the abutting surface 37 is a flat surface, the workability of the handle shaft 31 can be improved and cost reduction can be achieved.
[0094] Further, since in this case, the left end portion of the second outer peripheral portion 25 is crushed and deformed after abutting against the abutting surface 37, the abutting surface 37 abuts against the inner ring 15a, and finally, the portion that supports the screwing shaft force of the handle shaft 31 can be increased, so the strength can be improved.
[0095] The above-mentioned effects can also be obtained when the handle shaft 31 is screwed to the right side of the drive gear shaft 2.
[0096] Although the embodiments have been described above, the present application is not limited to the examples shown in the embodiments.
[0097] For example, although in the above-mentioned embodiments, the abutting portions 36, 36A are configured by the step structure formed on the boundary portion of the base portion 33 and the insertion portion 34 of the handle shaft 31, it is not limited thereto, and can be configured so that a flange-like peripheral wall or the like is partially formed on the outer peripheral portion of the handle shaft 31, and the side surface thereof abuts against the inner rings 15a, 16a. In this case, the same effects as those described in the above-mentioned embodiments can be obtained.
[0098] Further, although in the above-mentioned embodiments, the configuration in which the gap portions S1, S2 are formed on the drive gear shaft 2 is shown, it is not limited thereto, and if the configuration in which the crushing deformation is not generated, it can not be necessary to be provided. Further, the shape of the left end portion of the second outer peripheral portion 25 and the shape of the right end portion of the third outer peripheral portion 26 for forming the gap portions S1, S2 can be various shapes.
[0099] Further, although in the above-mentioned embodiments, the configuration in which the handle shaft 31 is connected to the arm portion 32 is shown, it is not limited thereto, and the handle shaft 31 can be integrally provided on the arm portion 32.
[0100] Further, although in the above-mentioned embodiments, the fishing spinning type reel 100 in which the cover member 13 is screwed to the side portion opening portion 11 is described, it is not limited thereto, and for the fishing spinning type reel in which the cover member is fixed to the reel body by a screw or other fixing unit, the present application can be appropriately applied.
