Description

Spinning reel drag mechanism

  The present invention relates to a drag mechanism, and in particular, a flange fixing screwed and fixed to the inner peripheral surface of the front end of the bobbin trunk to fix the front flange and the front flange disposed at the front end of the bobbin trunk. A spool having at least one locking groove formed in a drag housing recess formed in the inner peripheral surface of the bobbin trunk in the front-rear direction, and a spool shaft on which the spool is rotatably mounted And a spinning reel drag mechanism for braking the rotation of the spool.

  Some spinning reels are equipped with a mechanism for braking the spool, called a drag mechanism, in order to reduce the tension acting on the fishing line. As a drag mechanism, a front drag mechanism housed in a drag housing recess formed in an inner peripheral portion of a bobbin trunk around which a fishing line is wound is widely employed as a drag mechanism. A front flange portion is integrally or separately disposed at the tip of the bobbin trunk. In the case where the front flange portion is a separate body, a member using a flange fixing member that is screwed and fixed to the inner peripheral surface of the distal end portion of the drag housing recess is known to fix the front flange portion (see, for example, Patent Document 1).

In the conventional spinning reel, the threaded portion of the flange fixing member has a cylindrical portion, and a male screw portion that is screwed into a female screw portion formed on the inner peripheral surface of the bobbin trunk is formed on the outer peripheral surface of the cylindrical portion. Yes. Instead the flange fixing member screwed by bolts, when screwed to the inner peripheral surface of the bobbin trunk portion, it is not necessary to form a threaded hole for screwing the bolt between the thread winding body and the drag housing recess. For this reason, the thickness of the bobbin trunk can be reduced to increase the inner diameter of the drag housing recess, and the drag diameter can be increased, so that a larger drag force can be obtained. In particular, in the case of a deep groove type spool where the difference in outer diameter of the front flange portion from the bobbin trunk portion is large, the inner diameter of the drag storage recess is smaller than that of the shallow groove type. It is easy to obtain a large drag force by increasing the drag diameter.

  The conventional front drag mechanism has one or a plurality of drag washers housed on the inner peripheral side of the spool, and a drag knob that is screwed into the tip of the spool shaft and can adjust the amount of pressure applied to the drag washer. . The drag washer includes a first drag washer that cannot rotate with respect to the spool, and a second drag washer that cannot rotate with respect to the spool shaft, and two types of drag washers are alternately arranged. The first drag washer is provided with a pair of locking protrusions that engage with locking grooves formed on the inner peripheral surface of the drag housing recess on the outer peripheral portion. The pair of locking projections protrudes radially outward from the outer peripheral surface of the first drag washer and is disposed so as to face the diameter. When the locking projection engages with the locking groove, the first washer cannot be rotated with respect to the spool. A chamfered portion parallel to each other is formed at the tip of the spool shaft, and an oblong locking hole that engages with the chamfered portion is formed at the center of the second washer. When the locking hole engages with the chamfered portion of the spool shaft, the second washer cannot rotate with respect to the spool shaft.

As described above, when the drag washer is attached to the spool housing recess of the spool that fixes the front flange portion with the screw-type flange fixing member, the flange washer is attached to the bobbin trunk, and then the drag washer is attached to the drag housing recess. Installing. For example, one sheet of the second drag washer is mounted, and then the first drag washer is mounted so that the locking projection engages the locking groove. Since the two drag washers are mounted through the tube portion in which the male screw portion of the flange fixing member is formed, the outer diameter of the drag washer is smaller than the inner diameter of the tube portion. For this reason, the inner diameter of the drag housing recess in which the two locking grooves are formed on the inner peripheral surface is considerably smaller than the inner diameter of the cylindrical portion of the flange fixing member.
JP 2002-345369 A

In the conventional configuration, the inner diameter of the drag housing recess is smaller than the inner diameter of the cylindrical portion of the flange fixing member in order to mount the first drag washer having a pair of locking projections arranged opposite to each other. . For this reason, a drag diameter becomes small and it is difficult to obtain a larger drag force. If the inner diameter of the drag storage recess is the same as the inner diameter of the cylindrical portion, and the two locking projections are arranged opposite to each other on the diameter, the first drag washer is used when passing the cylindrical portion. It must be tilted greatly. For this reason, the length of the drag storage recess in the front-rear direction (spool axial direction length) is required by the length of the first drag washer in the state of being inclined in the cylinder, and the number of drag washers is small. When the length of the drag storage recess is short, the first drag washer cannot be stored. Therefore, when the longitudinal length of the drag housing recess is short, the inner diameter must be smaller than the inner diameter of the cylindrical portion, and the inner diameter of the drag housing recess cannot be increased.

  An object of the present invention is to provide a drag mechanism that is mounted on a spool in which a flange fixing member is screwed into a drag storage recess, so that the inner diameter can be increased as much as possible even if the drag storage recess has a short length in the front-rear direction. It is in.

  The spinning reel drag mechanism according to the present invention includes a spool shaft arranged along the front-rear direction, and a cylinder of the flange fixing member formed in the drag housing recess formed along the front-rear direction. The mechanism is disposed between the spool and the spool screwed therein, and is a mechanism for braking the rotation of the spool, and includes a first drag washer, a second drag washer, and a drag knob. The first drag washer has a plurality of locking projections arranged at a phase of one or 90 degrees or less that engages with the locking groove on the outer periphery, and is not rotatable with respect to the spool. At least one washer having a small outer diameter. The second drag washer is at least one washer which is arranged alternately with the first drag washer in the spool axis direction and cannot rotate with respect to the spool axis and has an outer diameter smaller than the inner diameter of the cylindrical portion. The drag knob is a knob that is screwed into the spool shaft and can adjust the amount of pressure applied to both drag washers.

  In this drag mechanism, for example, when one first drag washer is mounted between two second drag washers, the second drag washer with the flange fixing member mounted on the inner peripheral surface of the bobbin trunk. Is installed in the drag storage recess. Next, the phase is such that the locking projection engages with the locking groove, and the locking projection is tilted obliquely with the locking projection at the tip, and the first drag washer is passed through the inner periphery of the bobbin trunk. Attach to the surface. Then, after attaching the second drag washer, the drag knob is attached to complete the assembly of the drag mechanism. Here, since one or a plurality of locking projections provided on the first drag washer are arranged at a phase of 90 degrees or less in the case of a plurality, the maximum length of the first drag washer (a line connecting two locations of the outer shape) The maximum length of the conventional first drag washer in which the two locking projections are arranged opposite to each other on the diameter (the length of the longest line segment among the lengths of minutes) (the outer surface of the two locking projections) Is shorter than the length of As a result, when the first drag washer is tilted and passed through the cylindrical portion, the tilt of the first drag washer can be reduced, and the length in the front-rear direction (axial direction length) can be shortened. For this reason, even if it is a drag | storing recessed part with short front-back direction length, it becomes possible to enlarge an internal diameter as much as possible.

  The spinning reel drag mechanism according to a second aspect of the present invention is the mechanism according to the first aspect, wherein the number of the locking protrusions is one. In this case, since there is one locking projection, the length in the front-rear direction is further shortened compared to the case of a plurality of cases, the first drag washer can be easily inserted, and the length of the drag storage recess is further shorter. Even so, the inner diameter can be increased as much as possible.

The spinning reel drag mechanism according to a third aspect of the present invention is the mechanism according to the first or second aspect, further comprising a seal member that is disposed between the drag knob and the flange fixing member and prevents liquid from entering the both drag washers . In this case, since the flange fixing member has the cylindrical portion, the drag storing concave portion can be sealed only by mounting the sealing member between the inner peripheral surface of the cylindrical portion and the outer peripheral surface of the drag knob. The fluctuation of the drag force due to wetting can be reliably suppressed with a simple configuration.

  The spinning reel drag mechanism according to a fourth aspect of the present invention is the mechanism according to any one of the first to third aspects, further comprising a drag disk disposed between both drag washers. In this case, by arranging the drag disk between the washers, it is possible to smoothly slide between the drag washers when storing the drag.

  A spinning reel drag mechanism according to a fifth aspect of the present invention is the mechanism according to any one of the first to fourth aspects, wherein the spinning reel drag mechanism is detachably mounted between one end face of the cylindrical portion facing both of the drag washers and one of the two drag washers. And a retaining member for retaining both drag washers. In this case, since the retaining member can be prevented from coming off at the end face of the cylindrical portion, it is not necessary to provide a locking groove such as an annular groove for retaining the retaining member in the drag housing recess.

  According to the present invention, since the one or more locking projections provided on the first drag washer are arranged with a phase of 90 degrees or less in the case of a plurality, the maximum length of the first drag washer (two locations on the outer shape) The maximum length of a conventional first drag washer in which two locking projections are arranged opposite to each other in diameter on the length of the line segment connecting the two (length of the longest line segment) (one locking projection) Is shorter than the length connecting the outer side surfaces). As a result, when the first drag washer is tilted and passed through the cylindrical portion, the tilt of the first drag washer can be reduced, and the length in the front-rear direction (axial direction length) can be shortened. For this reason, even if it is a drag | storing recessed part with short front-back direction length, it becomes possible to enlarge an internal diameter as much as possible.

The second and third rear end support portions 17b and 17c are formed so as to penetrate the front and rear concentric with the second and third shaft support portions 16c and 16d of the intermediate support wall portion 16. The third rear end support portion 17c is formed on a protrusion portion 17e formed to protrude from the side portion 17d of the rear support wall portion 17. The protrusion 17e is thinner than the rear support wall 17 and is formed to be biased forward.

  The lid member 2b is made of a polyamide-based synthetic resin reinforced with glass fiber, for example, and is a member manufactured by an injection molding method. As shown in FIGS. 3 and 4, the lid member 2b is integrally formed with a second flange portion 24b as a wall portion on the rotor mounting side so as to cover the opening 25 of the reel body 2a and form a space inside. A thin cover portion 35 and an attachment leg portion 36 extending upward from the cover portion 35 are provided. The cover part 35 is formed thicker than the half of the thickness of the reel body 2 at the top, and the bottom part 35a is approximately half the thickness of the reel body 2 as the reel body 2a protrudes. An edge portion 35 b is formed on the upper and rear portions excluding the front portion of the cover portion 35 so as to face the opening 25. A step is formed in the rim portion 35 b so as to be in close contact with the opening 25. A substantially semicircular second flange portion 24b of the flange portion 2d is formed in the front portion of the cover portion 35. An inner portion protruding inward of the second flange portion 24 b functions as a wall portion that reinforces the cover portion 35.

The first and second movement restricting portions 38a and 38b restrict the movement. Further, the backward movement of the second guide shaft 29b is restricted by the cover recess 35c of the lid member 2b. Furthermore, since the retaining member 38 is restricted from moving backward by the reel body 2a and is swingably mounted on the second guide shaft 29b, the retaining member 38 is detached from the reel body 2a by another member such as a screw. The stopper member 38 does not need to be fixed, and the stopper member 38 does not fall off even when the lid member 2b is removed. As a result, it is possible to prevent the screw shaft 21 and the two guide shafts 29a and 29b from coming off while reducing the size of the reel body 2.

<Configuration of rotation transmission mechanism>
As shown in FIGS. 2 and 3, the rotation transmission mechanism 5 includes a master gear 11 including a face gear that rotates together with a handle shaft 10 to which the handle 1 is fixed, and a pinion gear 12 that meshes with the master gear 11. ing. The master gear 11 is integrally formed with a master gear shaft 11a on which the handle shaft 10 is mounted so as not to rotate. As shown in FIG. 3, the master gear shaft 11a is supported by bearings 45a and 45b mounted inside cylindrical first and second handle support portions 28a and 28b provided on the reel body 2a and the lid member 2b. The reel body 2a and the lid member 2b are supported so as to be rotatable about left and right axes that are different from the front and rear axes.

  A pinion gear 12 that is a rotating shaft of the rotor 3 is formed in a cylindrical shape, and a front portion 12 a passes through a center portion of the rotor 3 and is fixed to the rotor 3 by a nut 13. The pinion gear 12 has an axial intermediate portion and a rear end portion of a bearing 14a attached to the front support wall portion 27, and a bearing 14b attached to the first shaft support portion 16a of the intermediate support wall portion 16. Are respectively rotatably supported on the reel body 2. A spool shaft 15 passes through the inner peripheral side of the pinion gear 12.

<Configuration of oscillating mechanism>
As shown in FIGS. 2, 3, and 6, the oscillating mechanism 6 includes a spool shaft 15 connected to the center of the spool 4 via a drag mechanism 7 in the front-rear direction in conjunction with the rotation of the rotation transmission mechanism 5. This is a mechanism for moving the spool 4 in the same direction. The oscillating mechanism 6 includes a screw shaft 21 disposed in parallel with the spool shaft 15, a slider 22 that moves in the front-rear direction along the screw shaft 21, and an intermediate gear 23 that is fixed to the tip of the screw shaft 21. is doing. The oscillating mechanism 6 also includes first and second guide shafts 29a and 29b that guide the slider 22 in the front-rear axial direction, and a retaining member 38 that restricts the rearward movement of the screw shaft 21 and the second guide shaft 29b. And have.

The screw shaft 21 is disposed obliquely below the back side of the spool shaft 15 and is formed with a spiral groove 21a whose surface intersects. A front end small diameter portion 21c and a rear end small diameter portion 21d that are smaller in diameter than the spiral groove 21a formation portion are formed at both ends of the spiral groove 21a formation portion. As described above, the front and rear small wall portions 21c and 21d of the screw shaft 21 can be freely rotated by the first and second bushes 18 and 19 respectively attached to the front support wall portion 27 and the rear support wall portion 17. It is supported and mounted from the rear in a state in which forward movement is restricted. The screw shaft 21 is restricted from moving backward by a retaining member 38.

  The slider 22 has an engagement member 22 a that engages with the spiral groove 21 a inside, and reciprocates in the front-rear axis direction by the rotation of the screw shaft 21. The slider 22 is fixed to the rear end of the spool shaft 15 so as not to rotate. The slider 22 is guided in the front-rear direction by the first and second guide shafts 29a and 29b. As described above, when the slider 22 is guided by the two guide shafts 29a and 29b, the spiral groove 21a on the outer peripheral surface of the screw shaft 21 does not come into contact with the slider 22, and the generation of noise and vibration can be suppressed.

  The intermediate gear 23 rotates in conjunction with the rotation transmission mechanism 5. Specifically, a reduction gear unit 39 is provided between the intermediate gear 23 and the pinion gear 12 of the rotation transmission mechanism 5. The reduction gear unit 39 includes a large-diameter gear 39a that meshes with the pinion gear 12 and a small-diameter gear 39b that is disposed concentrically with the large-diameter gear 39a. The small diameter gear 39b meshes with the intermediate gear 23, and the rotation of the pinion gear 12 is transmitted to the screw shaft 21. For this reason, the back-and-forth movement speed of the oscillating mechanism 6 is slowed down, and the tight winding in which the fishing line is tightly wound around the spool 4 can be realized.

  The first guide shaft 29 a is disposed above the screw shaft 21. As described above, the first guide shaft 29a is attached to the second shaft support portion 16c of the intermediate support wall portion 16 in a state where the front end portion is restricted from moving forward, and the rear end portion of the first support shaft 29a is the rear support wall portion 17. It is supported by the second rear end support portion 17b. An annular locking groove 29c is formed on the front end side from the rear end portion of the first guide shaft 29a. This locking groove 29 c is locked to the retaining member 38. The rearward movement of the first guide shaft 29a is restricted by a retaining member 38 that fits into the locking groove 29c.

  The second guide shaft 29 b is disposed below the spool shaft 15. As described above, the second guide shaft 29b is mounted on the third shaft support portion 16d of the intermediate support wall portion 16 in a state where the front end portion is restricted from moving forward, and the rear end portion of the second support shaft 29b is the rear support wall portion 17. It is supported by the third rear end support portion 17c. The rearward movement of the second guide shaft 29b is restricted by a cover recess 35c formed in the lid member 2b. A locking groove 29c is also formed in the second guide shaft 29b, but this is formed in order to share both guide shafts 29a and 29b and is not used.

  As shown in FIGS. 3 and 5, the retaining member 38 is a metal plate-like member that is mounted on the reel body 2 in a state in which rearward movement is restricted and swings around the second guide shaft 29 b. It is installed freely. Specifically, the retaining member 38 is disposed in contact with the front surface of the rear support wall portion 17, thereby restricting rearward movement. The retaining member 38 is swingably attached to the first and second movement restricting portions 38a and 38b for restricting the backward movement of the first guide shaft 29a and the screw shaft 21, respectively, and the second guide shaft 29b. And a mounting hole 38c. The retaining member 38 is formed such that a side surface 38f on which the two movement restricting portions 38a and 38b are not formed is pressed against the lid member 2b. As a result, the retaining member 38 is pressed toward the reel body 2 a by the lid member 2 b, so that the retaining member 38 is less likely to rattle and the rear of the first and second guide shafts 29 a and 29 b and the screw shaft 21. The end can be regulated with high accuracy.

  The first movement restricting portion 38a is formed at a distance from the mounting hole 38c, and is a first member formed from the back side portion (right side in FIG. 3) of the retaining member 38 to the diagonally back side of the mounting hole 38c. It has a notch 38d. The first locking notch 38d is fitted in the locking groove 29c to restrict the rearward movement of the first guide shaft 29a. The second movement restricting portion 38b has a second locking notch portion 38e disposed between the mounting hole 38c and the first movement restricting portion 38a. The second locking notch 38e contacts the step surface 21e between the large diameter portion 21b in which the spiral groove 21a of the screw shaft 21 is formed and the rear end small diameter portion 21d, thereby moving the screw shaft 21 rearward. regulate. Further, as shown in FIGS. 4 and 6, locking groove portions 46a, 46b, and 35d for locking the retaining member 38 so as not to move back and forth are formed in the portions where the retaining member 38 is mounted on the reel body 2a and the lid member 2b. Has been. The locking groove portions 46a and 46b are formed in a pair of upper and lower portions in front of the rear support wall portion 17 of the reel body 2a. In addition to being pressed by the lid member 2b as described above, the locking member 38 is locked to the locking grooves 46a, 46b, and 35d, so that rattling of the locking member 38 can be further suppressed.

  When the oscillating mechanism 6 having such a configuration is incorporated into the reel body 2, the slider 22 is first mounted on the rear end of the spool shaft 15. At this time, the spool 4 is disposed at the most retracted position. Then, with the intermediate gear 23 placed at a predetermined position, the screw shaft 21 is inserted from the rear of the first rear end support portion 17a of the rear support wall portion 17 so as to penetrate the intermediate gear 23 and the front end small diameter portion 21c. 1 Mount on the bush 18. The first bush 18 is restricted from moving forward by the one-way clutch 51 as described above. As a result, the forward movement of the screw shaft 21 is restricted.

When the reel body 2 a is attached to the screw shaft 21, the second bush 19 is attached to the first rear end support portion 17 a of the rear support wall portion 17, and the rear end small diameter portion 21 d is supported by the second bush 19. When the mounting of the screw shaft 21 is completed, the first guide shaft 29a is inserted from the rear of the second rear end support portion 17b. Then, the front end is inserted into the second shaft support portion 16c of the intermediate support wall portion 16 through the slider 22, and the first guide shaft 29a is mounted on the reel body 2a. In this state, the retaining member 38 is mounted on the front surface of the rear support wall 17 formed on the reel body 2a and is locked by the locking grooves 46a and 46b. At this time, the first movement restricting portion 38a of the retaining member 38 is fitted and fitted in the locking groove 29c of the first guide shaft 29a to restrict the backward movement of the first guide shaft 29a. Further, the second movement restricting portion 38 b is brought into contact with the step surface 21 e of the screw shaft 21 to restrict the rearward movement of the screw shaft 21.

  Finally, the second guide shaft 29b is inserted from the rear of the third rear end support portion 17c. Then, the tip is inserted into the third shaft support portion 16d of the intermediate support wall 16 through the mounting hole 38c and the slider 22 of the retaining member 38, and the second guide shaft 29b is mounted on the reel body 2a. In this state, the rearward movement of the second guide shaft 29b and the second bush 19 is not restricted. However, when the lid member 2b is mounted on the reel body 2a, the backward movement is restricted by the cover recess 35c formed in the lid member 2b. In addition, when the cover member 2c is mounted on the reel body 2, the second bush 19 is restricted from moving backward by the protrusion 2f contacting the rear surface of the second bush 19.

  In the oscillating mechanism 6 having such a configuration, the first guide shaft 29a and the screw shaft 21 are prevented from moving backward, and the first and second movement restricting portions 38a of the retaining member 38 are restricted. It is regulated by 38b. Further, the backward movement of the second guide shaft 29b is restricted by the cover recess 35c of the lid member 2b. Furthermore, since the retaining member 38 is restricted from moving backward by the reel body 2a and is swingably mounted on the second guide shaft 29b, the retaining member 38 is detached from the reel body 2a by another member such as a screw. There is no need to fix the stopper member, and the stopper member 38 does not fall off even if the lid member 2b is removed. As a result, it is possible to prevent the screw shaft 21 and the two guide shafts 29a and 29b from coming off while reducing the size of the reel body 2.

  A reverse rotation prevention mechanism 50 for the rotor 3 is disposed inside the cylindrical portion 30 of the rotor 3. The reverse rotation prevention mechanism 50 includes a roller-type one-way clutch 51 and an operation mechanism 52 that switches the one-way clutch 51 between an operating state and an inoperative state. The one-way clutch 51 has an outer ring fixed to the front support wall 27 and an inner ring locked to the pinion gear 12 so as not to rotate. The operation mechanism 52 has an operation lever 53 disposed between the reel body 2a and the lid member 2b at the lower front end of the reel body 2, and the one-way clutch 51 is operated by swinging the operation lever 53. Switched between a state and a non-operational state. When the one-way clutch 51 is in the operating state, the rotor 3 cannot be rotated in the reverse direction, and when the one-way clutch 51 is in the inoperative state, the rotor 3 can be rotated in the reverse direction.

<Spool configuration>
The spool 4 is made of, for example, an aluminum alloy, and is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3, and is attached to the tip of the spool shaft 15 via the drag mechanism 7. Has been. As shown in FIG. 7, the spool 4 includes a cylindrical bobbin trunk 4a around which a fishing line is wound, a large-diameter tubular skirt 4b integrally formed at the rear end of the bobbin trunk 4a, and a bobbin And a front flange portion 4c disposed at the front end portion of the body portion 4a.

  The bobbin trunk 4a is formed with a circular drag storage recess 60 that opens forward. The front portion 60a of the drag housing recess 60 is formed to have a larger diameter than the rear portion 60b, and a female screw portion 60c into which the flange fixing member 55 is screwed is formed. Further, as shown in FIGS. 7 and 9, a locking groove 60d for preventing the drag mechanism 7 from rotating is opposed to the inner peripheral surface of the drag storing recess 60 from the front portion 60a to the rear portion 60b. One pair is formed. The pair of locking grooves 60d are formed along the spool shaft direction (front-rear direction).

Front flange portion 4c is has an inner portion 5 4a which is bobbin trunk 4a integrally formed, which is detachably attached to the inner portion 5 4a, for example made of hard ceramic ring of the outer part 54 b Yes.

The inner diameter of the cylindrical portion 55a is the same as the inner diameter of the rear portion 60b of the drag housing recess 60. Therefore, the inner diameter of the drag housing recess 60 is larger than that of the conventional spool.

<Configuration of drag mechanism>
As shown in FIGS. 7 and 8, the drag mechanism 7 is disposed between the spool 4 and the spool shaft 15, specifically, in the drag housing recess 60, and brakes the rotation of the spool 4 in the yarn feeding direction. This is a mechanism for applying a drag force to the spool 4. The drag mechanism 7 has a locking projection 61a that engages with the locking groove 60d, and a first drag washer 61 that is rotatably mounted on the spool shaft 15 and a first non-rotatably mounted on the spool shaft 15. For example, two second drag washers 62a and 62b disposed on both sides of the drag washer 61, and a drag knob 63 that can be screwed into the spool shaft 15 to variably adjust the amount of pressure applied to both drag washers 61, 62a, and 62b. And three drag disks 64a to 64c disposed between the drag washers 61, 62a and 62b and between the second drag washer 62b and the bottom of the drag storage recess 60, respectively. . The drag mechanism 7 includes a first sound generation mechanism 65 that generates sound when the drag is operated, and a seal member 66 that is disposed between the drag knob 63 and the flange fixing member 55.

The first drag washer 61 has an outer diameter smaller than the inner diameter of the cylindrical portion 55a of the flange fixing member 55, and is a metal disk-shaped member such as stainless steel. The outer diameter of the first drag washer 61 is preferably 95% to 99% of the inner diameter of the drag housing recess 60. If it exceeds 99%, it becomes difficult to store the first drag washer 61 in the drag storing recess 60, and if it is less than 95%, the drag diameter becomes small and it is difficult to obtain a large drag force.

  As shown in FIGS. 7 and 9, the first drag washer 61 has a circular hole 61b through which the spool shaft 15 penetrates at the center, and the above-described one locking projection 61a at the outer periphery. . The first drag washer 61 is attached to the drag housing recess 60 so as not to rotate with respect to the spool 4 by engaging the locking projection 61a with the locking groove 60d. The protrusion amount of the locking projection 61a is preferably in the range of 5% to 10% of the diameter of the first drag washer 61. When the protruding amount is less than 5%, a sufficient locking force cannot be obtained with respect to the drag force. On the other hand, if it exceeds 10%, it will be difficult to attach the first drag washer 61 through the cylindrical portion 55a.

As shown in FIG. 7, the second drag washers 62 a and 62 b have an outer diameter smaller than the inner diameter of the cylindrical portion 55 a of the flange fixing member 55, and are metal disk-like members such as stainless steel. The second drag washer 62a is a stepped disk-like member that protrudes forward, and is disposed in front of the first drag washer 61 with the drag disk 64a interposed therebetween. The second drag washer 62b has the first with the drag disk 64b interposed therebetween. It is arranged behind the one drag washer 61. A drag disk 64 c is disposed between the second drag washer 62 b and the bottom surface of the drag storage recess 60. The second drag washers 62a and 62b each have an oblong locking hole 62c that engages with a chamfered portion 15a formed at the tip of the spool shaft 15 in parallel with each other so as not to rotate. When the locking hole 62 c is engaged with the chamfered portion 15 a of the spool shaft 15, the second drag washers 62 a and 62 b cannot rotate with respect to the spool shaft 15.

  The drag disks 64a to 64c are, for example, felt disk-shaped members. The drag disks 64a to 64c are provided so that the first and second drag washers 61, 62a, 62b slide smoothly.

  Between the rear end surface of the cylindrical portion 55a of the flange fixing member 55 and the second drag washer 62a, specifically, between the rear end surface and the step surface between the front portion 60a and the rear portion 60b of the drag housing recess 60, A retaining spring 67 is attached to prevent the drag washers 61, 62a, 62b from falling off when the spool 4 is attached or detached. As shown in FIG. 8, the retaining spring 67 is formed by bending a metal elastic wire, and a corner portion is locked between the rear end surface and the step surface, and a connecting portion that connects the corner portions. Contacts the second drag washer 62a to prevent it from falling off.

When one first drag washer 61 is mounted between the two second drag washers 62a, 62b having such a configuration, as shown in FIG. 11 (a), the flange fixing member 55 is provided with the bobbin trunk 4a. In this state, the drag disk 64c, the second drag washer 62b, and the drag disk 64b are mounted in the drag storage recess 60 in this order. Next, the phase is set so that the locking projection 61a engages with one of the locking grooves 60d, and the locking projection 61a is inclined obliquely with the locking projection 61a at the tip, and is passed through the cylindrical portion 55a.

  Then, as shown in FIG. 11 (b), the first drag washer 61 is directed toward the locking groove 60d so that the locking projection 61a engages with the locking groove 60d when the tip passes through the cylindrical portion 55a. Move. As a result, the outer peripheral surface on the opposite side to the locking projection 61a is made to cover the cylindrical portion 55a, and as shown in FIG. 11 (c), the outer peripheral surface on the opposite side is swung around the locking projection 61a. Then, the first drag washer 61 is brought into contact with the drag disk 64b. Then, the drag disk 64a and the second drag washer 62a are mounted in this order, and finally the retaining spring 67 (see FIG. 8) is mounted to complete the mounting of the drag washers 61, 62a, 62b. Finally, after the drag washers 61, 62a, 62b are mounted, the drag knob 63 is mounted to complete the assembly of the drag mechanism 7.

  As shown in FIGS. 7 and 10, the drag knob 63 includes a knob body 70 for performing an operation of manually adjusting the drag force, and a pressing body that is rotatably attached to the knob body 70 while being prevented from coming off. 71, a coil spring 72 disposed between the knob body 70 and the pressing body 71, a retaining member 73 for retaining the pressing body 71 from the knob body 70, and a retaining member 73. And a second sound generation mechanism 75 that generates sound during the drag operation.

  The knob body 70 has a circular recess 70a formed in an opening at the rear end surface, and a circumferential interval from the front end surface to the front side of the rear end surface through the outer edge of the recess 70a and along the spool axial direction. It is a cylindrical member with a flange having, for example, four projection forming grooves 70b formed and made of synthetic resin, for example, injection molded. The protrusion forming groove 70b is formed in an arc shape on the outer edge of the fan-shaped through hole formed from the front end surface, and is formed from the rear end portion of the recessed portion 70a to the front side. A retaining ring 74 is engaged with a projection 70f formed at the formation end of the projection formation groove 70b. A through hole for forming the protrusion forming groove 70 b is hidden by a seal 79 attached to the front surface of the knob body 70. By sticking the seal 79 in this manner and closing the through hole, even if the projection forming groove 70b is formed by the through hole for molding, foreign matters such as water are difficult to enter inside.

  At the center of the knob body 70, a nut mounting portion 70c is formed on which a hexagonal nut 77 is mounted so that it cannot rotate but can move in the axial direction. A knob protrusion 70d formed in a substantially trapezoidal shape is formed on the front portion of the knob body 70 along the diameter. A mounting hole 70e for accommodating the second sounding mechanism 75 is formed on the rear surface of the knob body 70. The nut 77 is screwed into a male screw portion 15 b formed at the tip of the spool shaft 15.

  The pressing body 71 is disposed between the second drag washer 62 a and the knob body 70. The pressing body 71 is a member that is connected to the knob body 70 in a relatively rotatable state and is prevented from coming off in the axial direction, and is not rotatable with respect to the spool shaft 15. The pressing body 71 is disposed in contact with the rear end of the coil spring 72, and the pressing force to the drag washers 61, 62 a, 62 b is changed by the change in the spring force of the coil spring 72. The pressing body 71 has a bottomed cylindrical shape with a flange having a cylindrical portion 71a that protrudes rearward from the knob main body 70 and a ring-shaped flange portion 71b that has a larger diameter than the cylindrical portion 71a and is accommodated in the concave portion 70a. It is a member. On the inner peripheral portion of the cylindrical portion 71a, an oblong locking hole 71c is formed which is locked to a chamfered portion 15a formed at the tip of the spool shaft 15 so as not to rotate. A coil spring 72 is accommodated in the cylindrical portion 71a. A number of hemispherical sound holes 76 are formed side by side in the circumferential direction on the front end surface of the flange 71b. The pressing body 71 is connected to the knob body 70 in a state in which the pressing body 71 is prevented from coming off by a retaining member 73 and a retaining ring 74. The pressing body 71 is formed on the outer peripheral surface between the cylindrical portion 71a and the flange portion 71b and is mounted on the outer peripheral surface of the cylindrical portion 71a. And a seal mounting groove 71e for mounting the member 66.

  The coil spring 72 is mounted in a compressed state between the nut 77 and the pressing body 71. Specifically, the coil spring 72 is disposed in contact with the nut 77 and the bottom of the cylindrical portion 71a while being guided in the cylindrical portion 71a of the pressing body 71. The coil spring 72 is provided to gradually change the pressing force by rotating the knob body 70.

  The retaining ring 74 is a member formed by bending a metal wire having elasticity into a C shape. The retaining ring 74 is used so as to have a reduced diameter when mounted, and is slightly expanded when not mounted. The retaining ring 74 is locked to the protrusion 70f, and the retaining ring 74 contacts the rear surface of the retaining member 73. Thereby, the collar part 71b of the press body 71 is accommodated in the state where it was prevented from coming off by the recessed part 70a.

  The retaining member 73 is a substantially ring-shaped member made of, for example, a metal plate, which can be mounted on the mounting portion 71d of the pressing body 71. On the outer peripheral portion of the retaining member 73, a pair of protrusions that are engaged with four recesses 73 a that dodge the protrusions 70 f of the knob body 70 and two locking recesses 70 g formed at the rear of the knob body 70. There are two locking recesses 73c that are locked to a locking protrusion 70h formed between the locking recess 70g at the rear portion of the knob body 70 and the portion 73b.

  In order to prevent the pressing body 71 from coming off, the pressing body 71 is mounted in the recess 70 a of the knob body 70 in a state where the nut 77 is stored in the nut mounting portion 70 c and the coil spring 72 is stored in the pressing body 71. Then, the retaining member 73 is mounted on the mounting portion 71d of the pressing body 71 in a state where the protrusion 73b and the locking recess 73c are aligned with the locking recess 70g and the locking projection 70h. Finally, when the retaining ring 74 is hooked on the inner side surface of the protrusion 70f with the diameter reduced, the pressing body 71 is rotatably mounted in a state in which the pressing body 71 is prevented from coming off the knob body 70.

  The second sound generation mechanism 75 includes a sound output hole 76 formed in the pressing body 71, a sound output pin 80 mounted in the mounting hole 70 e, and a coil spring 78 that biases the sound output pin 80 toward the sound output hole 76. And have. A large number of sound output holes 76 are formed at intervals in the circumferential direction at positions that can face the mounting holes 70e. The sound output pin 80 is a pin having a large diameter at the center, a small diameter at the front and rear ends, and a tip that is rounded into a hemisphere. When the knob body 70 and the pressing body 71 are relatively rotated during the drag operation, the sound output pin 80 is output. Repeatedly pronounces collision with hole 76.

  The first sounding mechanism 65 is a mechanism that generates a sound when the spool shaft 15 and the spool 4 rotate relative to each other by the operation of the drag. As shown in FIG. 7, the first sound generation mechanism 65 includes a sound output member 81 that is non-rotatably mounted on the spool shaft 15, and a claw member 82 that is swingably mounted on the spool 4 and repeatedly collides with the sound output member 81. And a spring member (not shown) for biasing the claw member 82.

In the drag mechanism 7 having such a configuration, the locking protrusion 61a provided on the first drag washer 61 is combined into one, so that the maximum length L1 of the first drag washer 61 is two, as shown in FIG. This is shorter than the maximum length L2 (the length connecting the outer surfaces of the two locking projections) L2 of the conventional first drag washer in which the stop projections are arranged to face each other on the diameter. As a result, when the first drag washer 61 is inclined to pass through the cylindrical portion 55a, the inclination of the first drag washer 61 can be reduced, and the length in the front-rear direction (axial length) can be shortened. . For this reason, even if it is the drag | storing recessed part 60 with the short front-back direction length, an internal diameter can be enlarged now as much as possible.

<Reel operation and movement>
Adjust the drag force according to the size and type of fish before fishing. To adjust the drag force, the drag knob 63 is turned. When the drag knob 63 is rotated clockwise, for example, the urging force of the coil spring 72 is gradually increased by the nut 77 screwed to the spool shaft 15, and the pressing body 71 presses the second drag washer 62a via the coil spring 72. . This increases the drag force. At this time, the relative rotation between the pressing body 71 and the knob body 70 causes the sound generation pin 80 of the second sound generation mechanism 75 to repeatedly collide with the sound output hole 76 at a predetermined interval, thereby generating a crisp and light click sound.

  At the time of casting, the bale arm 44 is reversed to the yarn releasing posture. As a result, the first bail support member 40 and the second bail support member 42 swing. In this state, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then released vigorously due to the weight of the device. When the handle 1 is rotated in the yarn winding direction in this state, the rotor 3 is rotated in the yarn winding direction by the rotation transmission mechanism 5, and the spool 4 is moved back and forth by the oscillating mechanism 6 so that the bail arm 44 is moved back and forth. The fishing line is wound around the spool 4 by returning to the line winding position by a reversing mechanism (not shown).

  When the fish is caught in this state and the drag is activated, the spool 4 rotates with respect to the spool shaft 15. Then, the first sounding mechanism 65 sounds and notifies the angler of that. Then, the spool 4 rotates in the yarn feeding direction with the set drag force.

  Before fishing, a spool 4 around which a plurality of types of fishing lines are wound is prepared, and the spool 4 may be exchanged in accordance with fishing. In this case, the drag knob 63 is loosened and removed from the spool shaft 15. At this time, since the pressing body 71 is connected to the knob body 70 by the retaining member 73 and the retaining ring 74, the pressing body 71 does not fall off from the knob body 70. The drag washers 61, 62 a, 62 b are also prevented from coming off by the retaining spring 67, so that they will not fall off the spool 4.

  Since the retaining spring 67 and the retaining ring 74 having such a configuration are conventionally locked by an annular groove formed by machining, machining is necessary to form the groove. However, in the present embodiment, the retaining spring 67 is locked between the rear end surface of the cylindrical portion 55a and the step portion between the front portion 60a and the rear portion 60b of the drag housing recess 60, and the retaining ring 74 is formed by the knob body. Since it is locked by the projection 70f formed by the through-hole that can be formed at the time of molding of 70, machining for locking becomes unnecessary. For this reason, processing cost can be reduced.

<Other embodiments>
(A) In the above embodiment, the number of the locking protrusions 61a is one, but a plurality of the locking protrusions 61a may be provided. In FIG. 12, the first drag washer 161 has two locking projections 161a and 161a. In the drag housing recess 160, two locking grooves 160d and 160d are formed with a phase of 90 degrees. The amount of protrusion of each of the locking projections 161a and 161a is the same as in the above embodiment, and is in the range of 5% to 10% of the diameter of the first drag washer 161. The phase α of the two locking projections 161a and 161a is 90 degrees. The phase α is preferably 90 degrees or less. When the phase α exceeds 90 degrees, it is difficult to attach the first drag washer 161 to the drag housing recess 160 through the cylindrical portion 55a.

  (B) In the above embodiment, the number of drag washers is three, but the number of first and second drag washers may be any number as long as each is one or more.
