CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119 to Japanese Patent Application No. 2022-045008 filed on Mar. 22, 2022 in the Japanese Patent Office, the entire contents of which is hereby incorporated by reference.

FIELD

The present disclosure relates to a fishing spinning reel.

BACKGROUND

Conventionally, a fishing spinning reel in which a handle is attachable to and detachable from a reel body is known (see, for example, JP 2017-108717 A). In the fishing spinning reel disclosed in JP 2017-108717 A, the handle is attached by screwing a handle shaft into a drive gear shaft of the reel body. The fishing spinning reel includes 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 includes a drive gear and is rotatably supported via the ball bearing.

In the cylindrical member disclosed in JP 2017-108717 A, a portion facing an end of the drive gear shaft faces the end with a gap therebetween. On the other hand, the cylindrical member is configured to be buckled by abutting on the ball bearing supporting the drive gear shaft. As a result, JP 2017-108717 A prevents excessive application of the thrust of the handle shaft to the drive gear shaft due to screwing when the handle shaft is screwed into the drive gear shaft.

SUMMARY

In a structure disclosed in JP 2017-108717 A, a load acting on the drive gear shaft is prevented by the cylindrical member provided between the drive gear shaft and the handle shaft. For this reason, a connection structure of the drive gear shaft and the handle shaft becomes complicated, and it is necessary to manufacture each component with high dimensional accuracy, which leads to an increase in cost.

The present disclosure has been made to solve the above problems, and provides a fishing spinning reel that can simplify a connection structure of a drive gear shaft and a handle shaft and reduce cost.

In order to solve the above problems, the present disclosure provides a fishing spinning reel in which a handle is attachable to and detachable from a reel body. The fishing spinning reel comprises: a drive gear shaft that is provided in the reel body; a ball bearing that is externally fitted into the drive gear shaft and rotatably supports the drive gear shaft; and a handle shaft that is provided in the handle and is screwed into the drive gear shaft. The handle shaft is integrally provided with an abutting portion that abuts on an inner ring of the ball bearing by the screwing into the drive gear shaft.

In this fishing spinning reel, when the handle shaft is screwed into the drive gear shaft, the abutting portion of the handle shaft approaches and abuts on 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 in which the crimping force due to the screwing of the handle shaft is suppressed by the stopper of the abutting portion on the inner ring of the ball bearing. As a result, it is possible to prevent an end of the drive gear shaft from being buckled due to the screwing of the handle shaft.

Since the abutting portion is provided integrally with the handle shaft, it is not necessary to interpose a conventional cylindrical member between the drive gear shaft and the handle shaft. Therefore, a connection structure of the drive gear shaft and the handle shaft can be simplified, and cost can be reduced.

In addition, since the abutting portion is provided integrally with the handle shaft, the handle shaft can be manufactured with high dimensional accuracy, and the strength is increased as compared with a case of using a conventional cylindrical member.

In addition, even if the ball bearing is deformed due to excessive tightening of the handle shaft, it is sufficient to replace the ball bearing which is cheaper than the drive gear shaft, so that maintenance is easy and repair cost can be reduced.

Preferably, the handle shaft comprises a base portion that has a large diameter and an insertion portion that is formed to have a smaller diameter than the base portion and is inserted into the drive gear shaft. In this case, the abutting portion is preferably provided at a boundary portion between the base portion and the insertion portion.

In this configuration, the abutting portion can be easily formed using a stepped portion between the large-diameter base portion and the small-diameter insertion portion, and the connection structure of the drive gear shaft and the handle shaft can be simplified.

Preferably, the handle shaft comprises a high-strength material having higher strength than the ball bearing.

In this configuration, when the handle shaft is excessively tightened, the ball bearing cheaper than the drive gear shaft can be deformed. Therefore, the maintenance is easy and the repair cost can be reduced.

Preferably, an outer diameter of the end of the drive gear shaft is smaller than an inner diameter of the ball bearing.

In this configuration, it is possible to form a space for releasing the buckled and deformed portion between the end of the drive gear shaft and the inner ring of the ball bearing. As a result, even if buckling occurs at the end of the drive gear shaft due to the excessive tightening of the handle shaft, an influence thereof can be resolved in the space for buckling deformation. Therefore, the maintenance such as the ball bearing replacement can be easily performed.

Preferably, the abutting portion comprises a portion facing the ball bearing and a portion facing the end of the drive gear shaft, and forms a flat surface over both the portions.

In this configuration, since workability of the handle shaft is improved, the cost can be reduced.

Preferably, the abutting portion simultaneously abuts on the inner ring of the ball bearing and an end face of the drive gear shaft when the handle shaft is screwed into the drive gear shaft, or abuts on the inner ring of the ball bearing after abutting on the end of the drive gear shaft when the handle shaft is screwed into the drive gear shaft.

In the configuration in which the abutting portion simultaneously abuts on the inner ring of the ball bearing and the end of the drive gear shaft, the handle shaft can be fixed to the drive gear shaft in a state in which the crimping force due to the screwing of the handle shaft is suppressed by the stopper of the abutting portion on the inner ring of the ball bearing and the end of the drive gear shaft. That is, it is possible to increase a portion (area) that supports the axial force due to the screwing of the handle shaft and to improve the strength.

In addition, in the configuration in which the abutting portion abuts on the inner ring of the ball bearing after the abutting portion abuts on the end of the drive gear shaft, the abutting portion abuts on the inner ring of the ball bearing after buckling the end of the drive gear shaft by the abutting of the abutting portion. Therefore, even in this case, since the portion that supports the axial force due to the screwing of the handle shaft can be finally increased, the strength can be improved.

According to the present disclosure, it is possible to obtain a fishing spinning reel in which a connection structure of a drive gear shaft and a handle shaft can be simplified and cost can be reduced.

DETAILED DESCRIPTION

A fishing spinning reel100according to each embodiment will be described with reference to the drawings. In the following description, terms “front and rear” and “up and down” are based on directions illustrated inFIG.1, and terms “left and right” are based on directions illustrated inFIG.2.

First Embodiment

First, a basic structure of the fishing spinning reel100will be described.

As illustrated inFIG.1, the fishing spinning reel100comprises a reel body1to which a handle3is attached, a rotor4that is provided on the front side of the reel body1and rotates by a winding operation of the handle3, and a spool5that is provided on the front side of the rotor4and reciprocates in a front-rear direction by the winding operation of the handle3.

The reel body1comprises a body10that is provided with a side opening11opened toward the left side, a leg portion12that has a rod attachment portion12aextending upward from an upper portion of the body10and mounted on a fishing rod at a distal end, a lid member13that closes the side opening11, and a protective cover14that is attached to a rear portion of the body10.

A drive shaft cylinder (not illustrated in the drawings) and a spool shaft8(partially illustrated inFIG.2) are assembled to the reel body1so as to protrude forward from a front portion of the body10. The rotor4is attached to a front end of the drive shaft cylinder. The spool5is attached to a front end of the spool shaft8.

As illustrated inFIG.2, the lid member13comprises a cylindrical insertion portion13ato be inserted into the side opening11. A male screw portion is formed on an outer peripheral surface of the insertion portion13a. The male screw portion is screwed with a female screw portion formed on an inner peripheral surface of the side opening11. By this screwing, the body10and the lid member13are integrated.

The body10comprises a drive gear shaft2extending in a left-right direction and a spool reciprocating device60as a configuration for driving the drive shaft cylinder and the spool shaft8in conjunction with the operation of the handle3.

As illustrated inFIG.2, the drive gear shaft2comprises a drive gear21and a gear22. The drive gear shaft2is rotatably supported by the lid member13and the body10via left and right ball bearings15and16. A handle shaft31provided in the handle3is screwed into the drive gear shaft2. As a result, the handle3and the drive gear shaft2rotate integrally. Details of the drive gear shaft2and the handle3will be described later.

The spool reciprocating device60comprises a slider61and an interlocking gear62, and is configured such that the slider61moves in the front-rear direction along a guide shaft (not illustrated in the drawings) extending in the front-rear direction of the body10. The slider61is fixed to a rear end of the spool shaft8and comprises a guide groove61aopened to the right side. The interlocking gear62is supported by a support member63provided on a right side wall10aof the body10, and rotates while meshing with the gear22of the drive gear shaft2. The interlocking gear62comprises an eccentric protrusion portion62athat engages with the guide groove61aof the slider61.

As described above, when the drive gear shaft2and the gear22rotate by the winding operation of the handle3, the interlocking gear62rotates, and the rotational motion is converted into a front-rear motion of the slider61via the eccentric protrusion portion62aand the guide groove61a. As a result, the spool shaft8(spool5) reciprocates in the front-rear direction.

Next, the drive gear shaft2, the handle3, and a connection structure thereof will be described in detail.

As illustrated inFIG.2, the drive gear shaft2has a substantially cylindrical shape, and comprises a stepped circular outer peripheral surface along a center axis O1and screw holes23and23opened to the left and right. The handle3can be attached to the left side by the screw hole23of the left side, and the handle3can be attached to the right side by the screw hole23of the right side (seeFIG.5).

Each of the screw holes23has a large-diameter inner peripheral surface23aformed on the opening side and a small-diameter inner peripheral surface23bformed on the back side of the large-diameter inner peripheral surface23aand having a smaller diameter than the large-diameter inner peripheral surface23a. The female screws for screwing the handle shaft31are formed on the left large-diameter inner peripheral surface23aand the right small-diameter inner peripheral surface23b, respectively. The female screw of the left large-diameter inner peripheral surface23ais a reverse screw opposite to a normal screw. On the other hand, the female screw of the right small-diameter inner peripheral surface23bis a normal screw.

On the outer peripheral surface of the drive gear shaft2, the drive gear21is integrally formed at a position shifted leftward from the center portion in the left-right direction. Further, the gear22is integrally formed at a position shifted rightward from the center portion of the drive gear shaft2in the left-right direction. The drive gear shaft2and the drive gear21are formed of an aluminum alloy. Note that, in the fishing spinning reel (hereinafter, referred to as a “high-load fishing spinning reel”)100corresponding to a high-load winding operation of winding a fishing line under a situation where a high load acts, the drive gear shaft2may be formed of, for example, stainless steel or steel instead of the aluminum alloy.

Next, a connection structure on the left side of the drive gear shaft2will be described in detail with reference toFIG.3.

A first outer peripheral portion24continuous with the left side of the drive gear21and a second outer peripheral portion25continuous with the left side of the first outer peripheral portion24and having a diameter smaller than that of the first outer peripheral portion24are formed on a left outer peripheral surface of the drive gear shaft2. A ring-shaped stepped surface25aorthogonal to the center axis O1(seeFIG.2; the same is applied hereinafter) is formed between the first outer peripheral portion24and the second outer peripheral portion25. An outer peripheral surface of the second outer peripheral portion25functions as a seat surface in which the left ball bearing15is externally fitted. The stepped surface25afunctions as a positioning surface on which a right side surface of the inner ring15aof the left ball bearing15is positioned via an annular washer24a.

Note that an outer ring15bof the left ball bearing15is fitted into a circular inner peripheral surface of the lid member13centered on the center axis O1.

A left end of the second outer peripheral portion25has a size protruding leftward from a left side surface of an inner ring15aof the left ball bearing15. A left end outer peripheral surface25bof the second outer peripheral portion25is a tapered inclined surface that is narrowed toward the left end, and is separated from the inner ring15aof the left ball bearing15. As a result, an outer diameter of the left end of the drive gear shaft2is smaller than an inner diameter of the left ball bearing15.

Here, the left and right ball bearings15and16are formed of stainless steel.

Next, a connection structure on the right side of the drive gear shaft2will be described in detail with reference toFIG.4.

A third outer peripheral portion26continuous with the right side of the gear22is formed on a right outer peripheral surface of the drive gear shaft2. A positioning projection27protruding outward in a radial direction is formed on an outer peripheral surface of the third outer peripheral portion26. On the right side of the positioning projection27, the outer peripheral surface of the third outer peripheral portion26functions as a seat surface into which the right ball bearing16is externally fitted. A right side surface27aof the positioning projection27functions as a positioning surface where the left side surface of the inner ring16aof the right ball bearing16is positioned.

Note that the outer ring16bof the right ball bearing16is fitted into the right side wall10aof the reel body1on the left side of an annular inner peripheral portion10bcentered on the center axis O1via a washer10c. The cover member17is mounted on the right side wall10a(seeFIG.2).

A right end of the third outer peripheral portion26has a size protruding rightward from the right side surface of the inner ring16aof the right ball bearing16. Similarly to the left end outer peripheral surface25bdescribed above, the right end outer peripheral surface26bof the third outer peripheral portion26is a tapered inclined surface that is narrowed toward the right end, and is separated from the inner ring16aof the right ball bearing16. As a result, an outer diameter of the right end of the third outer peripheral portion26is smaller than an inner diameter of the right ball bearing16.

Next, the handle3will be described. As illustrated inFIG.2, the handle3comprises an arm portion32and a handle shaft31connected to the arm portion32and having a stepped circular outer peripheral surface along the center axis O1. The cover member3ais attached to a connection portion of the arm portion32and the handle shaft31.

The handle shaft31comprises a large-diameter base portion33connected to the arm portion32, and a small-diameter insertion portion34which is formed to be continuous with the base portion33and have a diameter smaller than that of the base portion33and is inserted into the screw hole23of the drive gear shaft2. The handle shaft31is formed of a high-strength material having higher strength than the drive gear shaft2, for example, stainless steel or steel. Note that the handle shaft31may be formed of another high-strength material, for example, a titanium alloy or an aluminum alloy.

Here, a relation between the strengths of the materials of the drive gear shaft2, the ball bearings15and16, and the handle shaft31is handle shaft31>ball bearings15and16>drive gear shaft2. Note that, in the high-load fishing spinning reel100, the relation between these strengths can be set as handle shaft31□ drive gear shaft2>ball bearings15and16. As another relation of the strengths, ball bearings15and16>handle shaft31□ drive gear shaft2can be set. As described above, in the setting in which the strengths of the ball bearings15and16are higher than those of the handle shaft31and the drive gear shaft2, it is possible to suppress the damage of the ball bearings15and16and to satisfactorily maintain rotation feeling of the handle3over a long period. In particular, in the high-load fishing spinning reel100, since the load acting on the drive gear shaft2is high, it is preferable to increase the strengths of the ball bearings15and16.

The base portion33has a substantially bottomed cylindrical shape having an opening on the side of the arm portion32, and has a hollow inside. The insertion portion34has a substantially columnar shape, and comprises a first insertion portion34acontinuous with a bottom portion of the base portion33and a second insertion portion34bcontinuous with the first insertion portion34a. The first insertion portion34acomprises an outer peripheral surface having a diameter smaller than that of the base portion33. An abutting portion36is integrally provided at a boundary portion between the base portion33and the first insertion portion34a.

As illustrated inFIG.3, the abutting portion36comprises a protrusion portion36aand an abutting surface36b. The protrusion portion36ahas a circular annular shape and protrudes rightward from an outer peripheral edge portion of the base portion33. The protrusion portion36ahas a substantially rectangular cross section. The protrusion portion36afaces the left side surface of the inner ring15aof the left ball bearing15, and is configured to abut on the left side surface of the inner ring15ain the process of fastening the handle shaft31to the drive gear shaft2.

The abutting surface36bis a ring-shaped flat surface that is continuous with the radially inner side of the protrusion portion36aand orthogonal to the center axis O1. The abutting surface36bfaces a left end face of the second outer peripheral portion25of the drive gear shaft2, and is configured to abut on the left end face of the second outer peripheral portion25in the process of fastening the handle shaft31to the drive gear shaft2.

In the present embodiment, the abutting surface36bis set to simultaneously abut on the left end face of the second outer peripheral portion25at timing when the protrusion portion36aabuts on the left side surface of the inner ring15a.

That is, both the protrusion portion36aand the abutting surface36bof the abutting portion36are used to abut on the second outer peripheral portion25and the inner ring15aon the side of the drive gear shaft2.

A gap portion S1is formed on the radially inner side of the protrusion portion36a. The gap portion S1is partitioned by the radially inner peripheral surface of the protrusion portion36a, the abutting surface36b, the left end outer peripheral surface25bof the second outer peripheral portion25, and the inner ring15aof the left ball bearing15, and has a substantially triangular cross section.

In the present embodiment, as described above, the abutting surface36bis set to simultaneously abut on the left end face of the second outer peripheral portion25at the timing when the protrusion portion36aabuts on the left side surface of the inner ring15a, but the present disclosure is not limited thereto. For example, when the protrusion portion36aabuts on the left side surface of the inner ring15a, a gap may be formed between the left end face of the second outer peripheral portion25and the abutting surface36b. That is, the handle shaft31may be fixed to the drive gear shaft2by crimping the protrusion portion36ato the inner ring15a.

Contrary to the above, in the process of fastening the handle shaft31to the drive gear shaft2, the abutting surface36bmay abut on the left end face of the second outer peripheral portion25, and then the protrusion portion36amay abut on the left side surface of the inner ring15a.

In this case, since the abutting surface36babuts on the left end face of the second outer peripheral portion25first in the process of fastening, it is possible to crimp the protrusion portion36ato the left side surface of the inner ring15awhile positively buckling and deforming the left end of the second outer peripheral portion25by the abutting of the abutting portion36comprising a high-strength material. At this time, the gap portion S1formed at the left end of the second outer peripheral portion25functions as a space for releasing the buckled and deformed portion. That is, the protrusion portion36acan be crimped to the left side surface of the inner ring15awhile promoting suitable buckling deformation of the left end of the second outer peripheral portion25.

FIG.5is an enlarged cross-sectional view illustrating a connection structure of the drive gear shaft2and the handle shaft31at the time of right-hand steering.

At the time of right-hand steering, the second insertion portion34bon the side of the distal end of the handle shaft31is screwed into the small-diameter inner peripheral surface23bon the back side of the screw hole23. The protrusion portion36aof the abutting portion36faces the right side surface of the inner ring16aof the right ball bearing16, and abuts on the right side surface of the inner ring16ain the process of fastening the handle shaft31to the drive gear shaft2.

On the other hand, the abutting surface36bfaces a right end face of the third outer peripheral portion26of the drive gear shaft2, and abuts on the right end face of the third outer peripheral portion26in the process of fastening the handle shaft31to the drive gear shaft2. Even in this case, the abutting surface36bis set to simultaneously abut on the right end face of the third outer peripheral portion26at timing when the protrusion portion36aabuts on the right side surface of the inner ring16a.

That is, the entire left side surface of the abutting portion36is used to abut on the third outer peripheral portion26and the inner ring16aon the side of the drive gear shaft2.

Even at the time of right-hand steering, the gap portion S1is formed on the radially inner side of the protrusion portion36a. The gap portion S1is partitioned by the radially inner peripheral surface of the protrusion portion36a, the abutting surface36b, the right end outer peripheral surface26bof the third outer peripheral portion26, and the inner ring16aof the right ball bearing16, and has a substantially triangular cross section.

As described above, the abutting surface36bis set to simultaneously abut on the right end face of the third outer peripheral portion26at the timing when the protrusion portion36aabuts on the right side surface of the inner ring16a, but the present disclosure is not limited thereto. For example, when the protrusion portion36aabuts on the right side surface of the inner ring16a, a gap may be formed between the right end face of the third outer peripheral portion26and the abutting surface36b. That is, the handle shaft31may be fixed to the drive gear shaft2by mainly crimping the protrusion portion36ato the right side surface of the inner ring16a.

Contrary to the above, in the process of fastening the handle shaft31to the drive gear shaft2, the abutting surface36bmay abut on the right end face of the third outer peripheral portion26first, and then the protrusion portion36amay abut on the right side surface of the inner ring16a.

In this case, since the abutting surface36babuts on the right end face of the third outer peripheral portion26first in the process of fastening, it is possible to crimp the protrusion portion36ato the left side surface of the inner ring16awhile positively buckling and deforming the right end of the third outer peripheral portion26by the abutting of the abutting portion36comprising a high-strength material. At this time, the gap portion S1formed at the right end of the third outer peripheral portion26functions as a space for releasing the buckled and deformed portion. That is, the protrusion portion36acan be crimped to the right side surface of the inner ring16awhile promoting suitable buckling deformation of the right end of the third outer peripheral portion26.

According to the present embodiment described above, for example, when the handle shaft31is screwed into the drive gear shaft2at the time of left-hand steering, the abutting portion36(protrusion portion36a) of the handle shaft31approaches and abuts on the inner ring15aof the left ball bearing15, and the handle shaft31is fixed to the drive gear shaft2. That is, the handle shaft31can be fixed to the drive gear shaft2in a state where the crimping force due to the screwing of the handle shaft31is suppressed by the stopper of the abutting portion36on the inner ring15aof the left ball bearing15. As a result, it is possible to prevent the end of the drive gear shaft2from being buckled due to the screwing of the handle shaft31.

In addition, since the abutting portion36is provided integrally with the handle shaft31, it is not necessary to interpose a conventional cylindrical member between the drive gear shaft2and the handle shaft31. Therefore, the connection structure of the drive gear shaft2and the handle shaft31can be simplified, and the cost can be reduced.

In addition, since the abutting portion36is provided integrally with the handle shaft31, the handle shaft31can be manufactured with high dimensional accuracy, and the strength is increased as compared with a case where a conventional cylindrical member is used.

In addition, since the abutting surface36bsimultaneously abuts on the left end face of the second outer peripheral portion25at the timing when the protrusion portion36aabuts on the left side surface of the inner ring15a, a portion (area) that supports the axial force due to the screwing of the handle shaft31can be increased, and the strength can be improved.

In addition, since the handle shaft31comprises a high-strength material having higher strength than the left ball bearing15, the following functions and effects are obtained in a case where a gap is set to be formed between the left end face of the second outer peripheral portion25and the abutting surface36bwhen the protrusion portion36aabuts on the left side surface of the inner ring15a. That is, even if the left ball bearing15is deformed by being pushed by the protrusion portion36adue to excessive tightening of the handle shaft31, it is sufficient to replace the left ball bearing15which is cheaper than the drive gear shaft2, so that maintenance is easy and repair cost can be reduced.

Conversely, when the abutting surface36babuts on the left end face of the second outer peripheral portion25, and then the protrusion portion36aabuts on the left side surface of the inner ring15a, the left end of the second outer peripheral portion25is buckled and deformed by the abutting of the abutting portion36, and then the abutting portion36abuts on the inner ring15a. Therefore, even in this case, since the portion that supports the axial force due to the screwing of the handle shaft31can be finally increased, the strength can be improved.

The functions and effects described above can be similarly obtained even when the handle shaft31is screwed into the right side of the drive gear shaft2.

Second Embodiment

A fishing spinning reel according to a second embodiment of the present disclosure will be described with reference toFIG.6. The present embodiment is different from the first embodiment in that an abutting portion36A has a flat surface.

The abutting portion36A comprises an abutting surface37orthogonal to a center axis O1. The abutting surface37forms a flat surface over both a portion facing a left side surface of an inner ring15aand a portion facing a left end face of a second outer peripheral portion25.

On the other hand, the left side surface of the inner ring15aand the left end face of the second outer peripheral portion25are also flush in a direction orthogonal to the center axis O1, and are set to be flat corresponding to the abutting surface37of the abutting portion36A.

As a result, in the process of fastening a handle shaft31to a drive gear shaft2, the abutting surface37of the abutting portion36A simultaneously abuts on the left side surface of the inner ring15aand the left end face of the second outer peripheral portion25. The same is also applied to a connection structure at the time of right-hand steering.

In the present embodiment, a gap portion S2having a different shape is formed at the left end of the second outer peripheral portion25instead of a gap portion S1described in the first embodiment. In the gap portion S2, a left end outer peripheral surface25cof the second outer peripheral portion25is a stepped surface having a small diameter.

According to the present embodiment described above, since the abutting surface37forming a flat surface is provided in addition to the same functions and effects as those described in the first embodiment, workability of the handle shaft31is improved. As a result, cost can be reduced.

In the present embodiment, the abutting surface37of the abutting portion36A is set to simultaneously abut on the left side surface of the inner ring15aand the left end face of the second outer peripheral portion25, but the present disclosure is not limited thereto. For example, when the abutting surface37abuts on the left side surface of the inner ring15a, a gap may be formed between the left end face of the second outer peripheral portion25and the abutting surface37. That is, the handle shaft31may be fixed to the drive gear shaft2by crimping the abutting surface37to the inner ring15a. Even in this case, since the abutting surface37is a flat surface, the workability of the handle shaft31is improved, and the cost can be reduced.

In addition, even if the left ball bearing15is deformed by being pushed by the abutting portion36A due to excessive tightening of the handle shaft31, it is sufficient to replace the left ball bearing15which is cheaper than the drive gear shaft2, so that maintenance is easy and repair cost can be reduced.

Conversely, the abutting surface37may abut on the left end face of the second outer peripheral portion25, and then the abutting surface37may abut on the left side surface of the inner ring15a. Even in this case, since the abutting surface37is a flat surface, the workability of the handle shaft31is improved, and the cost can be reduced.

In this case, the left end of the second outer peripheral portion25is buckled and deformed by the abutting of the abutting surface37and then the abutting surface37abuts on the inner ring15a, and a portion that supports the axial force due to the screwing of the handle shaft31can be finally increased, so that the strength can be improved.

The functions and effects described above can be similarly obtained even when the handle shaft31is screwed into the right side of the drive gear shaft2.

Although the embodiments have been described above, the present disclosure is not limited to the examples described in the embodiments.

For example, in the above embodiments, the abutting portions36and36A are configured using the stepped structure formed at the boundary portion between the base portion33and the insertion portion34of the handle shaft31. However, the present disclosure is not limited thereto, and a flange-shaped peripheral wall or the like protruding outward in the circumferential direction may be partially formed on the outer peripheral portion of the handle shaft31, and the abutting portions may be configured to abut on the inner rings15aand16ausing side surfaces thereof. Even in this case, the same functions and effects as the functions and effects described in the above embodiments can be obtained.

In the above embodiments, the gap portions S1and S2are formed in the drive gear shaft2. However, the present disclosure is not limited thereto, and the gap portions S1and S2may not be necessarily provided as long as buckling deformation does not occur. Further, the shape of the left end of the second outer peripheral portion25and the shape of the right end of the third outer peripheral portion26for forming the gap portions S1and S2can adopt various shapes.
