Description

  The present invention relates to a fishing spinning reel provided with a drag device that provides resistance to rotation of a spool around which a fishing line is wound.

  2. Description of the Related Art Conventionally, a drag device incorporated in a fishing spinning reel is, for example, as disclosed in Patent Document 1, in front of a spool that is rotatably supported at the tip of a spool shaft that moves back and forth by the rotation of a handle. The brake member is housed in the portion, and the adjustment knob that is screwed to the tip of the spool shaft is rotated to apply a pressing force to the brake member, thereby adjusting the frictional engagement force of the spool with respect to the spool shaft. ing.

  Further, in the drag device having the above-described structure, the spool is rotatably supported via a ball bearing (radial bearing) with respect to the spool shaft so that the fishing line can be drawn smoothly when the drag is operated. The rear end of the spool is fixed to the spool shaft so that the ball bearing is not damaged when the drag is tightened (the outer ring supported by the spool is damaged or deformed due to excessive thrust load applied by drag tightening). It is restricted in the axial direction in a state where it is in contact with a friction plate (a facing portion where the rear end portion of the spool faces).

JP 2007-202416 A

  In the drag device having the above-described structure, when the adjusting knob is rotated to press the braking member, the spool rear end is also in pressure contact with the friction plate that regulates the spool in the axial direction. And the frictional force of the rear end portion of the spool against the friction plate act (a plurality of frictional forces having different friction characteristics act). For this reason, the drag start is not stable and deteriorates, and in the region where the drag braking force is small where the smooth start is required, this effect is likely to occur, and a stable drag performance cannot be obtained. . In particular, the frictional force at the rear end of the spool with respect to the friction plate is easily affected by the material and surface treatment of the spool and the friction plate, and the adhesion of oil, grease, etc., so that the drag characteristics become more unstable.

  The present invention has been made paying attention to the above-mentioned problems, and is for fishing having a drag device that prevents damage and deformation of a ball bearing that rotatably supports a spool and that provides stable drag performance. An object is to provide a spinning reel.

In order to achieve the above object, a fishing spinning reel according to the present invention accommodates a braking member in a recess formed in a front portion of a spool rotatably supported by a spool shaft, and a tip portion of the spool shaft. In the configuration provided with a drag device that adjusts the frictional coupling force in the rotational direction of the spool with respect to the spool shaft by changing the pressure contact force of the braking member by rotating the adjusting body screwed to the spool shaft. The inner ring is supported by a support member that is fitted and fixed to the spool shaft, and the outer ring is supported by the spool so as to rotatably support the spool, and the support member . integrally provided, pairs so that a gap exists between the outer ring of the rear end portion and said ball bearing of said spool with devoted attached to the inner race of the ball bearing Possess a arranged facing portion, said gap when the applied thrust load by the drag device, as the rear end and the outer ring of the ball bearing of the spool is contactable with the facing portion, It is set to 0.1 mm or more and 0.2 mm or less .

  According to the spinning reel for fishing having the above-described configuration, when the drag is tightened by rotating the adjustment knob of the drag device attached to the front portion of the spool, the spool has a load (reel) along the spool axial direction. The load toward the main body side) is applied. Since the spool is rotatably supported with respect to the spool shaft via the ball bearing, the fishing line can be smoothly pulled out when the drag force is actuated. The spool shaft is integrally provided with a facing portion, and the facing portion is disposed so as to face the rear end portion of the spool and / or the ball bearing. Therefore, the frictional resistance is not given to the spool at the initial stage of braking when the braking force begins to act, and a smooth drag-out performance can be obtained. In addition, even if a large thrust force is applied to the ball bearing through the spool by setting the drag force to be large, contact is allowed in the clearance between the rear end of the spool and / or the ball bearing and the opposing portion. It is possible to prevent the ball bearing from being damaged or deformed by setting it to be possible.

  ADVANTAGE OF THE INVENTION According to this invention, the spinning reel for fishing provided with the drag apparatus which can prevent the failure | damage and deformation | transformation of the ball bearing which supports a spool rotatably, and can obtain the stable drag performance is obtained.

FIG.

  Hereinafter, embodiments of a spinning reel for fishing according to the present invention will be described in detail with reference to the drawings. In the spinning reel for fishing, the rotor is rotationally driven by winding a handle provided on the reel body, and the spool is reciprocated in the front-rear direction, whereby the rotor rotates with respect to the spool. The fishing line is wound evenly through the fishing line guide portion. In the drawing, the main body structure of the spinning reel is omitted because it is generally known, and a spool mounted on a spool shaft that is moved back and forth by a known oscillating mechanism mounted on the main body so as not to rotate, and the spool The drag device portion will be described in detail.

  1A and 1B show a first embodiment of a fishing spinning reel. FIG. 1A is a view showing a spool portion, and FIG. 1B is an enlarged view showing a main portion.

  A spool 1 around which a fishing line is wound has a cylindrical shape including a winding body 1a around which a fishing line is wound, a front collar 1b, and a rear cylindrical part (also referred to as a skirt) 1c. A substantially disc-shaped support wall (spool rear end) 1d is integrally formed on the inner side in the radial direction behind the rotating drum portion 1a. An opening 1e is formed at the center of the spool rear end 1d, and the spool shaft 2 is reciprocated along the front-rear direction (axial direction) via an oscillating mechanism (not shown). Is inserted.

  In this embodiment, a cylindrical support member (also referred to as a spool metal) 3 is fitted on the spool shaft 2, and the support member 3 is fixed to the spool shaft 2 by a support pin 4. It is externally fitted so that it cannot move in the axial direction. A ball bearing (bearing; radial bearing) 5 is disposed between the spool rear end 1d and a substantially central portion of the support member 3 (portion where the support pin 4 is inserted). The spool shaft 2 is rotatably supported.

  In the present embodiment, a projection 1f protruding toward the opening 1e is formed on the spool rear end 1d, and the drag device side of the outer ring 5a of the ball bearing 5 is positioned. Further, the support member 3 of the present embodiment is integrally formed with a flange 3a that protrudes radially outward from the ball bearing 5 on the reel body side. A protrusion 3b is formed that contacts the inner ring 5b of the bearing 5 to position the reel body side of the ball bearing 5. For this reason, the ball bearing 5 is in a state where a gap G ′ is generated between the ball bearing 5 and the flange 3a, so that the rotation of the bearing 5, that is, the rotation of the outer ring 5a to which the spool is fixed is not affected. .

  A spool click mechanism 7 is installed on the flange 3a of the support member. The spool click mechanism 7 includes an annular spring 7d held by a cap-like spring holding member 7a fixed radially outward of the flange 3a and a pair of openings 7c formed in the annular wall 7b of the spring holding member 7a. The ring spring 7d is engaged with the inner surface unevenness 1h of the annular wall 1g formed radially outward of the spool rear end 1d, so that a click sound is generated when the spool 1 rotates. Like to do.

  A ring-shaped braking plate 8 is attached to the outer side of the flange 3a of the support member 3 so as to sandwich a bent wall 7e bent substantially perpendicularly to the annular wall 7b of the spring holding member 7a. It is worn. The brake plate 8 is opposed to the spool rear end 1d (rear end surface 1d ') so as to be in contact with each other by generating a predetermined gap G.

  That is, in this embodiment, the brake plate 8 is attached to and integrated with the flange 3a of the support member 3, and the brake plate 8 constitutes a facing portion 10 that opposes the spool rear end portion 1d. It arrange | positions so that the said clearance gap G may arise between the edge part 1d and the opposing part 10. FIG.

In this case, with respect to the gap G, the outer ring 5a of the ball bearing 5 receives a thrust force at the time of adjusting the drag force of the drag device, which will be described later, via the projection 1f of the spool rear end, 1d (rear end surface 1d ′) is provided to prevent direct contact with the facing portion 10, and preferably 0.1 mm or more (dimension management is difficult if less than 0.1 mm). From 0.1 mm or more). However, if the gap G becomes too wide, the ball bearing 5 is damaged by deformation in the thrust direction due to excessive drag force (strong thrust load applied to the outer ring relative to the inner ring; thrust load that shears the inner ring and the outer ring). Since the tendency to deform becomes strong, it is preferable to set the thickness to 0.2 mm or less so that both can come into contact when a certain amount of thrust load is applied.
Note that the value of the gap G is appropriately set depending on the drag force specification, the spool material, the number of parts of the support portion, the processing accuracy, and the like.

  That is, with respect to the gap G, the state where the spool rear end 1d is not in contact with the facing portion 10 when the drag starts to slide (when the drag force is zero or when some drag force is applied). When a large load is applied to the ball bearing 5 due to the drag force acting (when a large load in the thrust direction is applied to the ball bearing), it is necessary to prevent damage and deformation after the spool. It suffices if the distance is such that the end 1d can come into contact with the facing portion 10. For this reason, when the drag force is set to zero, there is definitely a gap between the two.

  A concave portion 1A is formed on the front side (spool front portion) of the spool rear end 1d, and when the spool 1 rotates in the fishing line feed-out direction, a drag that applies a braking force to the rotation is provided. A device 20 is installed.

  The drag device 20 includes a drag force adjusting body (hereinafter referred to as an adjusting knob) 22 exposed forward from the concave portion 1A, and a friction braking portion (provided for applying a braking force to the spool). A braking member) 30, and a pressing member 40 that is installed between the adjustment knob 22 and the friction braking portion 30 and applies an axial pressing force to the friction braking portion 30 when the adjustment knob 22 is rotated. I have.

  The adjusting knob 22 is integrated with a nut member 23 that is screwed into the tip end portion of the spool shaft 2. When the adjusting knob 22 is screwed in, the adjusting knob 22 is disposed between the nut member 23 and the pressing member 40. The pressing member 40 presses the friction braking portion 30 through the pressing force of the compression coil spring (elastic member) 41.

  The friction braking portion 30 preferably has a multi-plate structure and is disposed along the outer peripheral surface of the support member 3, and a desired friction with the front surface 1 d ″ of the spool rear end portion 1 d. A force (braking force) is generated. Specifically, the friction braking unit 30 includes, for example, a metal washer (in the present embodiment, which constitutes a ratchet ring) 31 and a support member 3 whose inner peripheral portion is non-rotatably fitted to the support member 3. A metal washer 32 that is rotatably arranged, a metal washer 33 whose inner periphery is fixed to the support member 3 and a lining material 35 interposed therebetween are provided. ing. Then, the pressing member 40 is operated by rotating the adjusting knob 22 and pressed by the pressing force of the compression coil spring 41 corresponding to the screwing amount of the nut member 23, whereby the front surface 1d "of the spool rear end 1d. A desired pressure contact force is generated between the two and the frictional coupling force (braking force) in the rotational direction of the spool is adjusted.

  The pressing member 40 holds a click plate 42 that engages with the unevenness 31a formed on the inner surface of the ratchet ring 31, and when the adjustment knob 22 is rotated, the click plate 42 is brought into the unevenness 31a. A click sound is generated while being engaged.

Next, the effect of the drag operation in the fishing spinning reel configured as described above will be described.
Since the spool 1 is rotatably supported by a spool shaft 2 (a support member 3 fixed to the spool shaft 2) via a ball bearing 5, the fishing line can be drawn smoothly when the drag force is operated. It becomes possible to. Further, when the drag is tightened by rotating the adjusting knob 22 of the drag device 20 attached to the front portion of the spool 1, a braking force acts on the spool 1 via the front friction braking portion 30, and the spool 1 A braking force (drag force) can be applied to the rotation of. In this case, since the rear end portion 1d of the spool 1 and the ball bearing 5 are arranged so that there are gaps G and G 'between the opposing portion 10 and the braking force starts to act. Then, no frictional resistance is given to the spool 1 on the rear end side of the spool, so that a smooth drag-out performance of the drag can be obtained, and a stable drag performance can be obtained when a large load is not applied. become.

  When the adjustment knob 22 of the drag device 20 is tightly tightened, that is, when a large load is applied to the spool 1 toward the reel unit, the outer ring 5a of the ball bearing 5 is provided with a protrusion 1f at the rear end of the spool. However, since the rear end portion 1d (rear end surface 1d ') of the spool can come into contact with the facing portion 10 (friction plate 8), the ball bearing 5 can be prevented from being damaged or deformed. It becomes possible.

  In the present embodiment, the cylindrical support member 3 is fitted and fixed to the spool shaft 2, and the opposing portion 10 is integrally formed on the support member 3, so that the assembly accuracy can be improved, and the ball It becomes possible to form the gap G between the positioning of the bearing 5 and the opposed portion 10 with respect to the spool rear end 1d with high accuracy.

A simple ball bearing 5A is provided. In this case, since the ball bearing 5A is positioned by applying the outer ring 5a ′ to the projection 1f of the above-described embodiment, even if a large drag force is applied, the spool 5A is not affected. As in the embodiment described above, it is possible to prevent the ball bearing 5 from being damaged or deformed.

  Further, according to the configuration of this embodiment, since the spool 1 is supported by the plurality of ball bearings 5 and 5A, the rotation of the spool becomes smoother and a stable drag force can be applied.

  In such a configuration, when a large drag force is applied, the end surface (the flange portion 5d) of the ball bearing 5 can come into contact with the facing portion 10 (flange 3a), thereby preventing the ball bearing 5 from being damaged or deformed. It becomes possible to do. Further, with such a configuration, the structure can be simplified and the gap G can be easily maintained with the facing portion 10.

Further, the facing portion 10A is constituted by a spool-side surface 50a of a stopper 50 applied to the step portion 2A formed on the spool shaft 2, and a protrusion 50b is formed on the stopper 50 to form a ball bearing. 5 of the inner ring 5b is positioned. For this reason, a gap G ′ is formed between the stopper 50 and the ball bearing 5 as in the first embodiment described above.

  As described above, the ball bearings 5 and 5A that rotatably support the spool 1 may be arranged directly on the spool shaft 2, and the opposing portion 10 is also a shaft relative to the spool shaft 2. You may comprise by the member (for example, stopper 50 as shown in figure) fixed so that it might not move to a direction.
