Description

Technical Field

[0001] The present invention relates to a fishing reel, and more particularly to a fishing reel equipped with a one-way clutch that can prevent reverse rotation of a drive shaft. Background Art

[0002] Generally, a reverse prevention mechanism is provided on a fishing reel, i.e., a spinning reel. The reverse prevention mechanism allows rotation of the rotor in the fishing line winding direction during rotation operation of the handle, and prevents reverse rotation of the rotor when the handle is reversed. For example, as disclosed in Patent Document 1, the reverse prevention mechanism generally consists of a one-way clutch. The one-way clutch includes: an inner ring that is non-rotatably fitted to a pinion; a retainer that is disposed radially outside the inner ring and holds a plurality of rolling elements; and an outer ring that is disposed radially outside the retainer and is non-rotatably fixed to the reel body.

[0003] Since the one-way clutch is configured such that the outer ring portion is fitted into a cylindrical portion formed on the reel body, the two are in contact with each other, and there is a problem that corrosion (electrochemical corrosion) is likely to occur due to the difference in potential difference between dissimilar materials. Therefore, Patent Document 1 discloses a configuration in which a substantially cup-shaped protective cover that covers the outer ring member is provided between the outer ring and the reel body.

[0004] Patent Document

[0005] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2003-265078 Summary of the Invention

[0006] Since the above protective cover has a structure that is interposed between the inner peripheral surface of the cylindrical portion of the reel body and the outer peripheral surface of the outer ring on the radially outer side of the outer ring, there are limitations in miniaturization and weight reduction, and there is room for improvement.

[0007] The present invention has been made in view of the above problems, and the technical problem to be solved is to provide a structure that can prevent corrosion of the portion provided with the one-way clutch in a fishing reel equipped with the one-way clutch, and can achieve miniaturization and weight reduction of the reel body.

[0008] In order to achieve the above object, the fishing reel according to the present invention has: a drive shaft that is rotationally driven by the rotational operation of a handle rotatably supported on the reel body; a one-way clutch disposed on the drive shaft, having an inner ring, an outer ring, and a retainer that holds a plurality of rolling members; and a cylindrical portion provided on the reel body for housing the one-way clutch, characterized in that a protruding piece protruding radially outward is provided on the outer ring, a cutout portion penetrating radially is provided on the circumferential wall of the cylindrical portion for disposing the protruding piece, and an anti-corrosion plate is disposed axially overlapping the one-way clutch, and the anti-corrosion plate has a leg portion interposed between the protruding piece and the cutout portion.

[0009] According to the above fishing reel, a cutout portion penetrating radially is formed on the circumferential wall of the cylindrical portion provided on the reel body. Here, the protruding piece of the outer ring is disposed to be radially exposed and the outer ring is fixed against rotation. Thus, since the outer ring of the one-way clutch is not fixed against rotation by the radially inner peripheral side of the cylindrical portion of the reel body, the cylindrical portion can be made as small in diameter as possible, and miniaturization and weight reduction of the reel body can be achieved. In addition, since an anti-corrosion plate is disposed at the contact portion between the two components (the contact portion between the protruding piece and the cutout portion), even if the cylindrical portion of the reel body and the outer ring of the one-way clutch are made of different materials, corrosion of the reel body and the one-way clutch can be prevented.

[0010] Furthermore, the fishing reel according to the present invention has: a drive shaft that is rotationally driven by the rotational operation of a handle rotatably supported on the reel body; and a one-way clutch disposed on the drive shaft, having an inner ring, an outer ring, and a retainer that holds a plurality of rolling members, characterized in that a protruding piece protruding radially outward is provided on the outer ring, an abutting portion that abuts against two points on both sides of the protruding piece to restrict the rotation of the outer ring is provided on the reel body, and an anti-corrosion plate is disposed axially overlapping the one-way clutch, and the anti-corrosion plate has a leg portion in the portion where the protruding piece abuts against the abutting portion.

[0011] According to the above fishing reel, since a protruding piece is formed on the outer ring of the one-way clutch so as to protrude radially, and an abutting portion that abuts against two points on the side surface of the protruding piece to restrict the rotation of the outer ring is provided on the reel body, the structure of the portion for fixing the outer ring against rotation can be simplified. Thus, miniaturization and weight reduction of the reel body can be achieved. In addition, even if the abutting portion of the reel body and the outer ring of the one-way clutch are made of different materials, since an anti-corrosion plate is disposed at the contact portion between the two components (the portion where they abut at two points), corrosion of the reel body and the one-way clutch can also be prevented.

[0012] According to the fishing reel related to the present invention, a structure can be obtained that can prevent corrosion of the part provided with the one-way clutch and can achieve miniaturization and weight reduction of the reel body. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 and Figure 2 is a view showing a first embodiment of the fishing reel related to the present invention (in this embodiment, a spinning reel is shown as the fishing reel). First, an outline of the overall configuration of the spinning reel of this embodiment will be described. In addition, in the following description, the front and the rear refer to the Figure 2 directions shown.

[0024] On the spool body 2 of a spinning reel (hereinafter referred to as the reel) 1, a reel foot 2A for mounting on a fishing rod is integrally formed. In front of the spool body 2, there are provided: a rotor 3 rotatably supported; and a spool (not shown) supported to move back and forth in synchronization with the rotational movement of the rotor 3.

[0025] The rotor 3 has a pair of arms 3a that rotate around the spool. At the front end of each arm 3a, a guide ring support member 3b for mounting the base end of the guide ring 5 is rotatably supported between the fishing line winding position and the fishing line paying-out position. At this time, the base end of one side of the guide ring 5 is mounted on a fishing line guiding portion (line roller) 6, which is integrally provided on the guide ring support member 3b.

[0026] Inside the spool body 2, a handle shaft is rotatably supported by a bearing, and a handle is mounted on its protruding end. A driving force transmission mechanism 10 is provided on the handle shaft. When the handle is rotated, the driving force transmission mechanism 10 transmits its driving force to the rotor 3 to rotationally drive the rotor.

[0027] As is well known, the driving force transmission mechanism 10 includes: a driving gear integrally rotatably mounted on the handle shaft; and a pinion 11 having a pinion tooth portion meshing with the driving gear. The pinion 11 extends in the front-rear direction orthogonal to the handle shaft and has a function as a rotational driving portion (driving shaft). A hollow portion 11a extending in the axial direction is formed inside the rotational driving portion. At this time, a spool shaft passes through the hollow portion 11a. When the handle is rotated, the spool shaft engages with a well-known swing mechanism that moves the spool back and forth, and the spool is mounted on the top end of the spool shaft.

[0028] The pinion 11 is rotatably supported on the spool body 1. In addition, the pinion 11 extends toward the spool side, and the rotor 3 is integrally rotatably mounted on the top end of the pinion 11. The through hole of the protrusion 3A formed in the central portion of the rotor 3 is externally fitted on the top end of the pinion 11, and the rotor 3 can be fixed by a fastening nut (not shown). In addition, a one-way clutch 20 constituting an anti-reverse device is provided on the pinion 11.

[0029] With the above configuration, when the handle is wound, the rotor 3 is rotationally driven by the driving force transmission mechanism 10, and the spool moves back and forth in the front-rear direction through the swing mechanism and the spool shaft. Therefore, the fishing line is evenly wound around the spool through the fishing line guiding portion 6 of the rotationally driven rotor 3.

[0030] Next, refer to Figures 1 to 6The one-way clutch 20 of this embodiment will be described.

[0031] As Figure 1 shown, a base 2B formed in a substantially circular plate shape is provided on the reel side of the reel body 2, and a cylindrical portion 2C is provided on the surface portion of the base 2B in the axial direction. The pinion 11 passes through the central portion of the cylindrical portion 2C and is rotatably supported, and the one-way clutch 20 is provided in the middle portion thereof.

[0032] By the rotational operation of the handle, the pinion 11 is rotationally driven by the drive gear. The one-way clutch 20 is provided in the middle portion of the pinion 11, allowing rotation of the pinion 11 in the fishing line winding direction while preventing reverse rotation.

[0033] The one-way clutch 20 has an inner ring 21, an outer ring 27, and a retainer 23 that holds a plurality of rolling members 25, and has a cover member 23A integrated with the retainer 23. These elements (or some of the elements) can be pre-unitized.

[0034] The inner ring 21 is non-rotatable relative to the pinion 11 and has the function of a drive shaft that rotates integrally with the pinion 11. Specifically, the cross-section of the pinion 11 is formed in a shape with a non-circular portion locally, and by fitting the non-circular portion of the inner ring 21 to this portion, the inner ring 21 can rotate integrally with the pinion 11.

[0035] The retainer 23 is provided radially outward of the inner ring 21 and has holding portions 23a provided at regular intervals in the circumferential direction. A biasing spring 24 is provided on each holding portion 23a to bias the rolling members 25 disposed between the holding portions in the circumferential direction ( Figure 3 in the counterclockwise rotation direction; reverse rotation direction).

[0036] The outer ring 27 is provided radially outward of the retainer 23 and is formed in a substantially annular shape. On the inner peripheral surface of the outer ring 27, there are formed: a wedge region 27a that prevents rotation of each rolling member 25; and a free region 27b that allows the rolling members 25 to rotate freely. Each rolling member 25 held by the retainer 23 is in a state of being always biased toward the wedge region by the biasing spring 24. In addition, except for the portion where the following protruding piece 27c is formed, the outer peripheral surface 27d of the outer ring 27 is formed in a circular shape.

[0037] On a part of the outer ring 27, a protruding piece 27c is provided so as to protrude radially outward. This protruding piece functions as a stopper for restricting the rotation of the outer ring 27. The protruding piece 27c is integrally formed so as to protrude radially outward from the outer peripheral surface 27d of the outer ring 27, and is provided at one or more locations. At this time, when a large torque is applied to the outer ring, there is a possibility of stress concentration occurring at one location, resulting in imbalance, etc., so it is preferable to form two or more at equal intervals. In the present embodiment, two are provided at 180° intervals so as to be opposed to each other with the central axis X interposed therebetween. The protruding piece 27c has a certain width in the circumferential direction, and both circumferential sides 27e, 27f have an anti-rotation function.

[0038] On the cylindrical portion 2C protruding from the reel body 2, a cutout portion 2c is formed that penetrates its circumferential wall 2a in the radial direction. The cutout portion 2c is formed to such an extent that the aforementioned protruding piece 27c of the outer ring 27 can be fitted therein. By fitting the protruding piece 27c into the cutout portion 2c and disposing the surface 27g on the exposed side to be exposed in the radial direction, the outer ring 27 can be stopped and fixed (rotation restricted).

[0039] It is sufficient to form one or more of the aforementioned cutout portions 2c on the circumferential wall 2a, but in the present embodiment, two are formed at equal intervals in the circumferential direction (two that are symmetric with respect to the axis X at 180° intervals). That is, for the cutout portion, it is sufficient to provide the same number as the protruding pieces formed on the outer ring, whereby the one-way clutch can be stably held without loosening.

[0040] The outer surface of the protruding piece 27c is exposed in the radial direction at the cutout portion 2c of the cylindrical portion 2C and can be pressed against and pinched by a finger. Therefore, the outer ring 27 can be easily pinched using the exposed protruding piece, and thus the workability of attaching and detaching the one-way clutch 20 can be improved.

[0041] In addition, the above configuration is configured such that the diameter of the circumferential wall 2a of the cylindrical portion 2C (the diameter of the outer peripheral surface of the circumferential wall) is the same as the outermost diameter of the outer ring 27 (the diameter of the portion of the surface 27g on the exposed side of the protruding piece 27c). At this time, the outer ring 27 is configured to be fitted inside the circumferential wall 2a and there is a non-contact state (a gap S is generated) between the two. That is, when the inner ring 21 is centered, the non-contact state is maintained between the outer ring 27 and the circumferential wall 2a, and the two components are not electrically connected. In addition, by disposing the outer ring 27 in this way so that a gap S is generated, the rotational performance can be ensured, loosening can be prevented, and radial miniaturization can be achieved. And by slightly having a gap, it is possible to facilitate the attachment and detachment operation.

[0042] Further, in the present embodiment, a cover body (cover member) 23A that covers the retainer 23 and the outer ring 27 is mounted on the surface portion of the outer ring 27, and an annular electrochemically corrosion-preventing plate (corrosion-preventing plate; also referred to as a corrosion-preventing member) 28 is mounted on the cover member 23A (see Figure 5 , Figure 6 ). That is, the outer ring 27 is in a state of being clamped by the retainer 23 and the cover member 23A, and the corrosion-preventing plate 28 is placed on the outer peripheral side of the cover member 23A.

[0043] Generally, the outer ring of the one-way clutch is arranged to contact the cylindrical portion of the reel body. Generally, since the outer ring has a structure in which a corrosion-resistant film such as nickel plating is formed on SUS, if the reel body side is made of a non-metallic material such as ADC12 or a high-strength resin material treated with an alumina film, it is not easy to cause a corrosion problem between the two. However, if the reel body is formed of a magnesium-based metal material, the potential difference between the two increases and corrosion (electrochemical corrosion) is likely to occur.

[0044] In the above configuration, the contact portions between the outer ring 27 and the reel body 2 (cylindrical portion 2C) are the circumferential sides 27e, 27f of the cutout portion 2c and the protruding piece 27c in contact therewith. Therefore, it is only necessary to insulate this portion. The corrosion-preventing plate 28 of the present embodiment is configured to be axially detachable in a manner overlapping the one-way clutch 20, and is configured as a plate-shaped and annular body so as not to increase the size of the reel body.

[0045] Figure 5 It is a diagram showing a configuration example of the corrosion-preventing plate.

[0046] As Figure 5 and Figure 6 shown, the corrosion-preventing plate 28 of the present embodiment is located radially outside the cover member 23A and has an annular main body 28a placed on the surface portion of the cover member 23A. Protruding pieces 28b protruding radially outward are respectively formed on both radial sides of the main body 28a, and a pair of legs 28c hanging axially are provided on both sides of each protruding piece 28b.

[0047] The protruding piece 28b is formed in substantially the same shape as the protruding piece 27c of the outer ring 27, and the legs 28c are configured to be inserted between the circumferential sides 27e, 27f of the protruding piece 27c and the cutout portion 2c when the main body 28a is axially placed on the surface portion of the outer ring 27.

[0048] The anticorrosion plate 28 only needs to be interposed between two components (intervening between a pair of feet 28c) and be made of non-conductive insulating material. For example, when the reel body (cylindrical part) is made of magnesium, it is preferable to use a raw material with a small potential difference from the outer ring, such as an aluminum-based material (aluminum alloy after alumina film treatment). Since such a raw material can be easily fabricated by stamping or the like and is configured to be non-magnetic, it will not be attracted by a magnet even if the following magnetic seal mechanism is provided, and since an alumina film layer is formed, it will not conduct electricity either. In addition, even if aluminum is crushed during the static strength test, an alumina film layer will remain on the surface, so it is possible to obtain a result that no electricity conduction occurs after the static strength test. And since the shape is stable during stamping, it is convenient to load or unload, and it will not affect the rotatability either.

[0049] Of course, for the constituent material of the anticorrosion plate, it is only necessary to select an appropriate raw material according to the raw materials of the outer ring 27 and the reel body, and it can also be made of other metal materials, resin materials, or the like.

[0050] In addition, in order to restrict the axial movement of the one-way clutch 20, a restricting plate (not shown) may be provided adjacent to the one-way clutch.

[0051] The one-way clutch 20 configured as described above is unitized and installed in the cylindrical portion 2C. At this time, as Figure 1 and Figure 2 shown, in order to improve the waterproof and dustproof effects on the one-way clutch 20, a magnetic seal mechanism 50 may be provided.

[0052] As is well known, the magnetic seal mechanism 50 includes: annular magnetic plates (pole plates) 51, 52 arranged with a minute gap intervening between the outer peripheral surface of the drive shaft (inner ring 21); and an annular magnet 53 sandwiched between the magnetic plates and configured such that a magnetic fluid is filled in the gap between the drive shaft and the magnetic plates (refer to Figure 1 , Figure 2 ).

[0053] In addition, in the present embodiment, a waterproof cover 60 is provided on the reel body so as to enclose the cylindrical portion 2C and the one-way clutch 20. The waterproof cover 60 has a shape including a cylindrical portion 61 surrounding the one-way clutch 20 and a cover portion 62 for closing the opening on the reel side, and the magnetic plate 51 of the magnetic seal mechanism 50 is in close contact with the inner surface of the cover portion 62.

[0054] According to the one-way clutch 20 configured as described above, rotation (reverse rotation) of the handle (rotor 3) in the fishing line paying-out direction can be prevented.

[0055] That is, when the handle is rotated in the fishing line winding direction to rotate the drive pinion 11 (inFigure 3 When rotating in the clockwise rotation direction (rotation drive), the inner ring 21 also rotates in the same direction together with the pinion gear 11. At this moment, since the rolling members 25 held by the retainer 23 move to the free area 27b of the outer ring 27, the rotational force of the inner ring 21 is not transmitted to the outer ring 27, and thus the rotor 3 can rotate smoothly together with the pinion gear 11.

[0056] On the contrary, when the inner ring 21 rotates in reverse together with the pinion gear 11 (the rotor 3 rotates in the fishing line paying-out direction), the rolling members 25 held by the retainer 23 rotate in the counterclockwise rotation direction and are located in the wedge area 27a of the outer ring 27 by the biasing spring 24. Therefore, the rotational force of the inner ring 21 can be transmitted to the outer ring 27. Since the rotation of the outer ring 27 is restricted by the protruding piece 27c, it becomes a stopper to prevent the reverse rotation of the pinion gear 11 and the rotor 3.

[0057] In addition, in the above configuration, a cutout portion 2c penetrating in the radial direction is formed on the circumferential wall 2a of the cylindrical portion 2C on the side of the reel body, and here, the protruding piece 27c formed on the outer ring 27 of the one-way clutch 20 is disposed to be exposed in the radial direction, and the outer ring 27 is fixed against rotation.

[0058] That is, since the outer ring 27 is not fixed against rotation by a groove or a protrusion formed on the inner peripheral surface of the cylindrical portion as in the prior art, the cylindrical portion 2C can be made as small in diameter and as thin-walled as possible, and thus miniaturization and weight reduction of the reel body can be achieved.

[0059] Moreover, in the present embodiment, in the above configuration, the annular corrosion prevention plate 28 is placed on the cover member, and its leg portion 28c is interposed between the contact portion (cutout portion 2c) of the outer ring 27 (protruding piece 27c) of the one-way clutch and the cylindrical portion 2C, so that corrosion of the reel body can be prevented. At this moment, since the corrosion prevention plate 28 is housed in the opening portion of the cylindrical portion 2C, the structure around the one-way clutch is not complicated, and miniaturization and weight reduction of the entire reel can be achieved.

[0060] In addition, since the protruding pieces 27c of the outer ring 27 are symmetrically arranged in the radial direction, they can be easily pinched, facilitating the installation and removal operations of the one-way clutch.

[0061] In addition, in the present embodiment, while the magnetic seal mechanism 50 is disposed on the spool side of the one-way clutch 20, a waterproof cover 60 is provided so as to cover the cylindrical portion 2C and the one-way clutch 20, thereby preventing the intrusion of foreign matters such as moisture and dust and improving durability.

[0062] Figure 7 and Figure 8This is a diagram showing a second embodiment of the spinning reel for fishing according to the present invention.

[0063] The one-way clutch 20 of this embodiment has the same configuration as that of the first embodiment, and protruding pieces 27c are formed on the outer ring 27 at 180° intervals. In addition, similar to the Figure 6 configuration shown, a cover member 23A that clamps the outer ring 27 together with the retainer 23, and an anti-corrosion plate 28 mounted on the cover member 23A are also installed on the one-way clutch of this embodiment.

[0064] In this embodiment, an abutting portion 2E is formed on the reel body 2 to abut against the side surface of the protruding piece 27c of the outer ring 27 to restrict the rotation of the outer ring. For the abutting portion 2E, it does not have to be configured as a cylindrical shape as in the first embodiment, as long as the structure protrudes in the axial direction and abuts against the side surface of the protruding piece 27c to restrict rotation. Therefore, it is only necessary to configure one protruding piece on the outer ring and set it to restrict its bidirectional rotation by abutting at two points on both circumferential sides of the protruding piece.

[0065] In addition, since in this embodiment, two protruding pieces 27c are formed on the outer ring 27 at 180° intervals, abutting portions 2E are provided on both circumferential sides of each protruding piece, and it is configured to abut at two points (the side surface 2E′ of the abutting portion 2E) on both circumferential sides of the protruding piece respectively.

[0066] According to such a configuration, similar to the above-described first embodiment, it is possible to prevent corrosion of the reel body by the anti-corrosion plate 28, and at the same time, the one-way clutch can be stopped and fixed without providing a cylindrical portion with a cutout, and weight reduction and miniaturization can be achieved. In addition, since there is a space generated around the abutting portion in such a configuration, it is convenient to assemble and disassemble the one-way clutch 20.

[0067] And, such an abutting portion 2E is preferably formed to perform two-point abutment at a position more radially inward than the outermost diameter position of the protruding piece 27c of the outer ring 27.

[0068] Since in such a configuration, the abutting portion 2E can be made thinner-walled, weight reduction can be further achieved.

[0069] The anti-corrosion plate 28 of the above-described embodiment (refer to Figure 5 ) is composed of a component different from the one-way clutch, is located radially outside the cover member 23A of the retainer 23, and is formed as a ring placed on the surface portion of the cover member 23A, but it can also be a configuration provided on a component of the one-way clutch 20.

[0070] For example, it can also be configured such that an anti-corrosion part is detachably mounted on the retainer 23, which is a component of the above-described one-way clutch, between both sides 27e and 27f (refer to Figure 3 ) of the spool body (cutout part 2c) and the protruding piece 27c. Alternatively, such an anti-corrosion part can be configured to be integrally formed with the retainer. In addition, it can also be configured such that the same anti-corrosion part is detachably mounted on the cover part 23A side of the retainer, and it can also be integrally formed with the cover part 23A. Moreover, it can also be a configuration in which anti-corrosion parts are provided on both the retainer 23 and the cover part 23A.

[0071] Thus, by providing the anti-corrosion component on the components of the one-way clutch, the number of parts can be reduced and the assemblability can be improved.

[0072] In addition, for such an anti-corrosion part (anti-corrosion component), it only needs to be configured such that no electrochemical corrosion occurs between the one-way clutch and the spool body, and its shape and raw material can be appropriately deformed.

[0073] As described above, although the embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments and can be variously deformed.

[0074] For the protruding piece 27c having the above-described configuration, its shape can be appropriately deformed. For example, the surface 27g on the exposed side of the protruding piece may or may not protrude radially from the cylindrical part 2C within the cutout part 2c of the cylindrical part 2C. In addition, although in the Figure 8 shown configuration, it is configured to abut against the abutting part 2E on both circumferential sides of the protruding piece, a recess may be formed in advance along the axial direction in the central part of the protruding piece, and the abutting part may be formed to be embedded in the recess. Alternatively, an abutting part having a semi-H-shaped cross-section and extending axially may be provided on the spool body to abut against both sides of the protruding piece 27c. In addition, for the anti-corrosion plate (anti-corrosion component), as long as it is configured to insert a component having an anti-corrosion effect between the one-way clutch and the spool body, its shape can be appropriately deformed.

[0075] In addition, although in the above-described embodiment, the retainer 23 is made fixed to prevent the reverse rotation of the rotor, it can also be the following structure, that is, an operating part protruding to the outside of the spool body is provided, and the retainer is rotated by the operation of the operating part to place the rolling part in the free area and allow the reverse rotation of the rotor.

[0076] And although in the present embodiment, a spinning reel is exemplified as a fishing reel, it can also be applied to other reels (double-bearing type reels) equipped with a one-way clutch, etc.
