Description

  The present invention relates to a fishing reel that incorporates a rolling one-way clutch to prevent reverse rotation of a rotary drive shaft.

  Usually, a fishing reel is configured to wind a fishing line around a spool via a power transmission mechanism by rotating a handle. For example, in a spinning reel as a fishing reel, a rotor having a fishing line guide portion is rotated via a drive shaft by rotating a handle, and the fishing line is wound around a spool. Further, such a fishing reel is equipped with a reverse rotation prevention device so that the rotor does not reverse due to the feeding of the fishing line wound around the spool during actual fishing.

  As such a reverse rotation prevention device, a device using a rolling one-way clutch is generally known in order to reduce the degree of reverse rotation at the time of fishing operation and improve the reliability of the hooking operation.

  For example, in Patent Document 1, in order to reduce the strength burden of the fitting support portion of the reel body that holds and supports the one-way clutch in a non-rotating manner, an anti-rotation locking is provided at the opening edge of the outer ring of the one-way clutch. A non-rotating member that engages with the non-rotating locking notch is fixed to the reel unit, and the outer ring of the one-way clutch is fixed to the reel unit via the non-rotating member. It is disclosed.

Japanese Patent No. 3860051

  According to the structure disclosed in Patent Document 1, although the burden on the strength of the fitting support portion of the reel body can be reduced, another member and a fixing member for preventing the outer ring of the one-way clutch from rotating are required. This increases the number of parts and the number of assembly steps, thereby increasing the manufacturing cost. In addition, the weight increases as the number of parts increases.

  The present invention has been made paying attention to the above circumstances, and an object of the present invention is to provide a small and lightweight fishing reel capable of reducing the number of parts and the number of assembling steps and efficiently reducing the manufacturing cost. There is.

  In order to solve the above-described problems, the present invention provides a rolling one-way clutch that allows rotation in one direction and prevents rotation in the other direction between a rotary drive shaft that is rotated by a handle and the reel body. In the fishing reel designed to prevent reverse rotation of the rotary drive shaft, a locking stop formed on the outer ring of the rolling one-way clutch is removed from a bearing that rotatably supports the rotary drive shaft. It is possible to engage with an engaging portion formed on a retaining member for stopping, and the outer ring of the one-way clutch is prevented from rotating on the reel body via the retaining member.

  According to the above-described configuration, the outer ring of the one-way clutch is configured to be prevented from rotating around the reel body while also serving as a bearing retaining member that rotatably supports the rotary drive shaft, so that the number of parts and assembly man-hours can be reduced. Manufacturing cost can be reduced efficiently.

  In the above configuration, the outer ring of the rolling type one-way clutch is formed as a substantially cylindrical body having a closed end portion that is substantially closed by insertion of the rotary drive shaft and an open end portion on the opposite side. A stop locking portion may be formed at the open end of the outer ring of the one-way clutch and engaged with the engagement portion of the retaining member.

  According to such a configuration, as a rational arrangement form, generally, the open end portion of the outer ring having the detent locking portion is positioned on the side facing the bearing that rotatably supports the rotary drive shaft. Therefore, the axial dimension of the reel can be shortened as compared with the arrangement in which the open end of the outer ring faces away from the bearing (the closed end of the outer ring faces the bearing). That is, in general, a fishing reel is provided with a switching operation mechanism that extends from the bearing side to the one-way clutch side and switches the one-way clutch between a reverse rotation possible position and a reverse rotation prevention position. In order to connect the switching element of the mechanism to the component of the one-way clutch inside the outer ring, the switching element extends in the axial direction of the reel, but the open end of the outer ring is located on the side facing the bearing. Then, compared with the case where the open end portion of the outer ring faces away from the bearing, the axial extension length of the switching element of the switching operation mechanism (the protruding amount of the switching element toward the front side of the reel) Therefore, the axial dimension of the reel can be shortened (the reel can be miniaturized), and the weight can be reduced accordingly. In addition, if the non-rotating locking portion is formed at the open end of the outer ring in this way, the retaining member can be fitted into the cylindrical outer ring through the open end. Thus, the axial dimension of the reel can be further shortened, and further downsizing of the reel (shortening of the axial dimension) can be further promoted.

  ADVANTAGE OF THE INVENTION According to this invention, the small and lightweight fishing reel which can reduce a number of parts and an assembly man-hour, and can reduce manufacturing cost efficiently can be provided.

  Hereinafter, embodiments of a fishing reel according to the present invention will be specifically described with reference to the accompanying drawings.

  1 to 7 show a spinning reel as a fishing reel according to a first embodiment of the present invention. As shown in FIG. 1, a reel leg 1 of a spinning reel according to this embodiment is integrally formed with a reel leg 2 to be attached to a fishing rod, and a rotor 3 rotatably supported in front of the reel leg 2. And a spool 4 supported so as to be able to move back and forth in synchronism with the rotational movement of the rotor 3.

  The rotor 3 includes a pair of arm portions 3a (only one is shown in FIG. 1) that rotates around the spool 4, and a base of a bail 3b is provided at each front end portion of each arm portion 3a. A bail support member 3c having an end attached thereto is rotatably supported between a fishing line winding position and a fishing line discharge position. Note that one base end portion of the bail 3b is attached to a fishing line guide portion (not shown) provided integrally with the bail support member 3c.

  A handle shaft 5 is rotatably supported in the reel body 1, and a handle 6 is attached to the protruding end portion. The handle shaft 5 is engaged with a take-up drive mechanism. The take-up drive mechanism meshes with the drive gear 7 and a drive gear 7 mounted on the handle shaft 5 so as to be integrally rotatable. A pinion 8 is provided as a rotational drive shaft that extends in a direction orthogonal to the handle shaft 5 and has a hollow portion extending in the axial direction therein.

  The pinion 8 is rotatably supported in the reel body 1 via a bearing 9 and extends toward the spool 4 side, and the rotor 3 is attached to the tip portion. The bearing 9 is prevented from coming off in the axial direction by a retaining member 37 inserted between the bearing 9 and a rolling one-way clutch 10 described later.

  The pinion 8 has a rolling one-way clutch 10 attached to an intermediate portion thereof (front side of the reel (spool 4 side) with respect to the bearing 9), and a switching operation lever provided outside the reel body 1. A known reverse rotation prevention mechanism (stopper) is configured to operate the one-way clutch 10 by rotating 11 and prevent reverse rotation of the handle 6 (rotor 3) in the fishing line feeding direction.

  A spool shaft 12 extending in a direction perpendicular to the handle shaft 5 and having the spool 4 mounted on the tip side is inserted into the hollow portion formed in the pinion 8 so as to be movable in the axial direction. The pinion 8 is engaged with a known spool reciprocating device 13 for reciprocating the spool 4 (spool shaft 12) back and forth.

  In the fishing spinning reel having such a configuration, when the winding operation is performed by the handle 6, the rotor 3 is driven to rotate through the winding drive mechanism, and the spool 4 is moved through the spool reciprocating device 13. Since it is reciprocated back and forth, the fishing line is evenly wound around the winding body 4a of the spool 4 via the fishing line guide.

  As shown in FIG. 2, the rolling one-way clutch 10 includes an inner ring 21 that is non-rotatably fitted to the pinion 8, a cage 27 that is disposed outside the inner ring 21, and an outer side of the cage 27. The outer ring 25 is disposed on the outer periphery of the outer ring 25, and the outer periphery thereof is protected by the protective cover 50.

  On the inner peripheral surface of the outer ring 25, a free rotation region where the plurality of rolling members 28 held by the cage 27 can freely rotate and a wedge region which prevents the rotation of the plurality of rolling members are formed. Each rolling member 28 is urged toward the wedge region by a spring member provided in the cage 27.

  The outer ring 25 forms a substantially cylindrical body having a closed end 25c that is substantially closed by the insertion of the pinion 8 therethrough and an open end 25b on the opposite side, and the bearing 9 and the rolling one-way clutch. Rotation with respect to the reel body 1 is prevented by the retaining member 37 inserted between Specifically, as clearly shown in FIG. 3, a pair of engaging portions 37 a projecting radially outwards are provided in the circumferential direction on a part of the retaining member 37 in the form of an annular ring in the circumferential direction. They are provided at an angular interval of 180 degrees, and these engaging portions 37a are locked to a notch-shaped detent locking portion 25a of the outer ring 25 provided at a corresponding position. Then, by screwing the screw 30 attached to the engaging portion 37a into the reel body 1 (see FIGS. 3, 5, 6 and 7), the outer ring 25 is attached to the reel body 1 via the engaging portion 37a. It has been stopped. In the present embodiment, the locking stopper 25 a is formed at the open end 25 b of the outer ring 25 and is engaged with the engaging portion 37 a of the retaining member 37. That is, in the present embodiment, the outer ring 25 is disposed in a state where the open end portion 25 b faces the bearing 9. Therefore, in this embodiment, the retaining member 37 is fitted into the cylindrical outer ring 25 through the open end 25b in order to shorten the axial dimension of the reel (see FIG. 2).

  As described above, in this embodiment, the anti-rotation locking portion 25a formed on the outer ring 25 of the rolling one-way clutch 10 is formed on the retaining member 37 that prevents the bearing 9 that rotatably supports the pinion 8 from coming off. The outer ring 25 of the one-way clutch 10 is prevented from rotating around the reel body 1 through the retaining member 37. The annular retaining member 37 prevents the bearing 9 from coming off in the axial direction by the retaining portion 37b on the inner peripheral side thereof coming into contact with the outer ring 9a of the bearing 9 (see FIGS. 3, 5 and 6). .

  In the one-way clutch 10 having such a configuration, when the inner ring 21 rotates forward together with the pinion 8 (the rotor 3 rotates in the fishing line winding direction), the rolling member 28 of the retainer 27 is positioned in the free rotation region of the outer ring 25. Therefore, the rotational force of the inner ring 21 is not transmitted to the outer ring 25 (not blocked by the outer ring 25), and thus the rotor 3 rotates together with the pinion 8 without any trouble. On the other hand, when the inner ring 21 is rotated together with the pinion 8 (the rotor 8 rotates in the direction of feeding the fishing line), the rolling member 28 of the retainer 27 is located in the wedge region of the outer ring 25. The force is transmitted to the outer ring 25, which serves as a stopper and prevents the pinion 8 and the rotor 3 from rotating (reversely rotating).

  The operation of the reverse rotation preventing mechanism with such a one-way clutch 10 can be controlled by the switching operation lever 11. Specifically, as shown in FIGS. 2 and 3, the switching operation lever 11 has a switching cam 33 that extends substantially parallel to the spool shaft 12 in the reel body 1, and the tip of the switching cam 33. The protrusion 33a is engaged with and connected to the engagement hole 52 of the extension 27a extending in the radial direction of the cage 27. Therefore, in this configuration, when the cage 27 is rotated via the switching cam 33 by rotating the switching operation lever 11, the rolling member 28 held by the cage 27 is attached to the spring member. A reversible position where the rotor 3 is forcibly held in the free rotation region of the outer ring 25 against the force (a position where the rotor 3 can be rotated in reverse), and the rolling member in the wedge region of the outer ring 25 by the biasing force of the spring member It is possible to selectively switch between a reverse rotation preventing position (a position where reverse rotation of the rotor 3 is prevented) to be positioned.

  As described above, the fishing reel according to the present embodiment also serves as the retaining member 37 of the bearing 9 that rotatably supports the pinion 8 as a rotation drive shaft, and the outer ring 25 of the one-way clutch 10 is reeled. Since it is configured to prevent the body 1 from rotating, the number of parts and the number of assembly steps can be reduced, and the manufacturing cost can be reduced efficiently.

  Further, in the present embodiment, the anti-rotation locking portion 25a is formed at the open end 25b of the outer ring 25 of the one-way clutch 10 and is engaged with the engagement portion 37a of the retaining member 37, that is, Since the open end portion 25b of the outer ring 25 having the locking engagement portion 25a is located on the side facing the bearing 9 that rotatably supports the pinion 8, the open end portion 25b of the outer ring 25 is separated from the bearing 9 by a surface. Compared to the arrangement configuration (the closed end 25c of the outer ring 9 faces the bearing 9), the axially extending length of the switching elements 33, 33a of the switching operation mechanism including the switching operation lever 11 is shortened. Therefore, the axial dimension of the reel can be shortened (the reel can be miniaturized) and the weight can be reduced accordingly. Further, since the effect of reducing the number of parts, the effect of shortening the extending length in the axial direction of the switching elements 33 and 33a, and the position of the cage 27 are in the rear (direction of the bearing 9), the center of gravity of the entire reel Can be brought close to the base of the reel leg 2 on the side where the reel leg 2 is attached to the heel, improving operability.

  8 to 10 show a spinning reel as a fishing reel according to a second embodiment of the present invention. As shown in FIG. 8, in the spinning reel according to the present embodiment, the direction of the outer ring 25 of the one-way clutch 10 is opposite to that of the first embodiment. That is, the outer ring 25 of the present embodiment is disposed so that the closed end portion 25 c faces the bearing 9. Therefore, in such a configuration, in order to make the retaining member 37 function as a retaining member for the bearing 9 and a retaining member for the outer ring 25 as in the first embodiment, the retaining member for the outer ring 25 is prevented. 25a and the structure of the engaging portion 37a of the retaining member 37 need to be different from those of the first embodiment.

  For this purpose, in this embodiment, the retaining member 37 has an engagement portion 37a ′ protruding in the axial direction toward the outer ring 25 (see FIG. 9), while the outer ring 25 is A notch-shaped detent locking portion 25a ′ that can be engaged with the engaging portion 37a ′ is provided on the outer peripheral surface of the closed end portion 25c (see FIGS. 8 and 10). Other configurations are the same as those in the first embodiment.

  As described above, even when the closed end portion 25 c of the outer ring 25 is disposed so as to face the bearing 9, the retaining member 37 can serve as a function of retaining the bearing 9 and preventing the outer ring 25 from rotating. It is possible to obtain the same effects as those of the first embodiment.

  Note that the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the invention, such as the position and shape of the locking stopper formed on the outer ring and the locking section formed on the retaining member. Needless to say, this can be done. For example, in the above-described embodiment, the description has been made with the configuration in which the rolling one-way clutch is provided in the intermediate portion of the pinion. However, the rolling one-way clutch may be provided on the handle shaft, and the position thereof is specified. Not. In the above-described embodiment, the present invention is applied to a spinning reel. However, it goes without saying that the present invention can be applied to other reels including a dual-bearing type reel, and the type of reel is not limited.
