Description

  The present invention relates to a fishing spinning reel.

  A conventional general fishing spinning reel is provided with a bail support member having a fishing line guide portion on a rotor rotatably supported by a reel body, and the bail support member is moved from a fishing line winding position to a fishing line discharge position. It is the structure supported so that rotation was possible. The rotor is rotationally driven through a drive mechanism housed in the reel body by rotating the handle, and the fishing line is moved against the spool reciprocated by the drive mechanism. Is wound through a fishing line guide.

  When the fishing line is released, the bail support member is reversed from the fishing line winding position to the fishing line release position to release the fishing line. After the fishing line is released, the bail support member is returned to the original fishing line winding position and the handle is rotated. By doing so, the fishing line is wound around the spool via the fishing line guide.

  The spool shaft that forms part of the drive mechanism is fitted with a spool and a drag braking member, and the tightening adjustment of the braking member is performed by a drag brake adjusting body screwed into the tip of the spool shaft. By doing so, the drag braking force is adjusted.

  By the way, at the time of actual fishing, the fishing line wound around the spool may drop off due to a change in the tension of the fishing line or wind, and may enter the spool and get entangled with the spool shaft. In such a case, it is necessary to remove the spool from the spool shaft and untangle the fishing line. Also, when replacing a fishing line, the spool may be removed and replaced with a spool around which another fishing line is wound. In these cases, it is necessary to loosen the drag adjusting body and remove the drag adjusting body from the tip of the spool shaft. However, the drag adjusting body may be accidentally dropped and lost. There was a possibility. For example, if it is dropped into the sea and recovery becomes difficult, it becomes impossible to continue fishing with the spinning reel.

Therefore, conventionally, a mechanism for preventing the drag adjuster from being dropped is provided to prevent the drag adjuster from falling (for example, see Patent Documents 1 and 2).
In Patent Document 1, a spring is used so that the drag adjusting body is hooked on the spring to prevent the drop adjusting body, and by dragging the drag adjusting body, the drag adjusting body is released and the drag adjusting body is spooled. It is configured to be removable from the shaft.
On the other hand, in Patent Document 2, a washer is provided on the drag adjusting body, and the washer is configured to be screwed to the screw of the spool shaft even after the screw adjusting screw is released from the spool shaft, thereby preventing falling off. Further, the drag adjusting body can be detached from the spool shaft by releasing the screwing of the washer.

Normally, fishing spinning reels are used in places where the usage environment is severe, so that during sea fishing, seawater and foreign matter can easily enter the drag mechanism through the gap between the spool and the drag adjuster. There's a problem.
However, Patent Documents 1 and 2 have not been devised for such intrusion.
Therefore, it is conceivable to combine a known drag mechanism waterproofing technique with the dropout prevention techniques described in Patent Documents 1 and 2. However, if it does so, the increase from the viewpoint of the increase in the number of parts and a design structure will increase, and it has not realized.

  The present invention has been made to solve the above-described problem, and can appropriately prevent the drag adjusting body from falling off, and can be used to prevent dust and water from being applied to a braking member constituting the drag mechanism. It is an object to provide a spinning reel.

  A fishing spinning reel of the present invention that solves such a problem is a cylindrical spool that is attached to a spool shaft that is supported by a reel body so as to be movable back and forth, and that can accommodate a braking member that forms a drag mechanism inside. A fishing spinning reel comprising: a drag adjuster that is screwed to a tip of the spool shaft, and that is capable of adjusting a frictional coupling force of the brake member by abutting on the brake member by a tightening force by screwing. , The spool or the drag adjuster is protruded from one side to the other side so that a space formed between the spool and the drag adjuster is closed, and the tip peripheral portion is the other end. An elastically deformable waterproof seal member that is slidably contacted with the opposite surface on the other side, and protrudes from the opposite surface on the other side toward the one side, and the tip peripheral portion of the waterproof seal member is engaged and disengaged. An engagement projection that is engaged with the spool, and the tip peripheral portion of the waterproof seal member is engaged with the engagement projection in a state in which the drag adjuster is not screwed to the spool shaft. It is possible to stop.

According to this fishing spinning reel, the elastically deformable waterproof seal member protrudes so as to close the space formed between the spool and the drag adjusting body, and the tip peripheral portion faces the other side. Since it is slidably contacted with the surface, the sealability between the spool and the drag adjuster can be ensured while allowing the drag adjuster to move.
Furthermore, since the front end peripheral portion of the waterproof seal member is releasably locked to the locking protrusion in a state where the screw adjustment body is released from the spool shaft, the screw adjustment body is released. After that, the drag adjusting body can be locked to the spool by the action of elastic force.

  Further, the present invention is characterized in that the waterproof seal member protrudes from the spool side toward the drag adjuster side, and the tip peripheral portion is in sliding contact with the opposing surface of the drag adjuster. To do.

  According to this fishing spinning reel, the inner peripheral portion that is the tip peripheral portion of the waterproof seal member is in sliding contact with the opposing surface of the drag adjuster. On the contrary, from the drag adjuster side to the spool side. The length (circumference) of the portion that comes into sliding contact can be shortened as compared with the case where the waterproof seal member is projected toward the outer periphery and the outer peripheral portion that is the tip peripheral portion comes into sliding contact with the opposing surface of the spool.

Further, in the present invention, in a state where the drag adjusting body is screwed to the spool shaft, the length that can be screwed between the spool shaft and the drag adjusting body is set to Ln, and the length of the opposing surface on the other side is set to Ln. the length from the contact position of the tip circumferential portion to the retaining projection is taken as L _1, and satisfies the Ln <L _1.

According to this fishing spinning reel, the length from the contact position of the tip peripheral portion on the opposite surface on the other side to the locking projection is longer than the length Ln that allows the spool shaft and the drag adjusting body to be screwed together. because it is the L ₁ is longer, in a state where the screwed state is started to be released by loosening the drag regulation member, can position the tip peripheral portion of the waterproof seal member on opposite sides of the other side.

Further, the present invention provides a waterproof sealing member in a state where the distal end peripheral portion is locked to the locking protrusion when the drag adjusting member is loosened and the drag adjusting member is removed from the spool shaft. The drag adjuster can be tilted in the removing direction, the length of the spool shaft and the drag adjuster that can be screwed is Ln, and the drag adjuster is tightened to the maximum from the position where the drag adjuster is tightened. the length of the drag adjusting member to the tip peripheral portion by loosening the fastening to a position where the locking projection abuts moves as L _1, when the waterproof seal member is inclined to the removal direction of the drag regulation member the length of the portion to be inclinable in the waterproof seal member and L _2, the inclination angle of the portion where the waterproof seal member is the inclined movable when inclined in detaching direction of the drag adjuster and theta _1, before The projection height from the opposing surface of the other side of the locking projection when the _{L 3, Ln> L 1,} sinθ 1 = (Ln-L 1) / L 2, L 3> L 2 (1 −cos θ ₁ ) are all satisfied.

  According to this fishing spinning reel, when the above-mentioned formulas are satisfied, the waterproof seal member is engaged with the locking protrusion at the tip peripheral portion in a state where the threaded engagement between the spool shaft and the drag adjusting body is released. While maintaining the stopped state, the drag adjusting body is inclined in the removal direction, and the drag adjusting body is held by the spool.

  Further, the present invention is characterized in that at least one of the tip peripheral portion and the locking projection is provided with a holding means for holding the locking between the tip peripheral portion and the locking projection. And

  According to this fishing spinning reel, the holding means can suitably hold the tip circumferential portion and the locking projection, and the locking state between the spool and the drag adjusting body can be easily maintained. .

  Further, according to the present invention, when the waterproof seal member is attached by screwing the drag adjuster to the spool shaft, the distal end peripheral portion is disposed on the locking protrusion that moves in the attaching direction of the drag adjuster. It is pressed and can be inclined in the attachment direction of the drag adjuster, and the inclination angle is set to be smaller than the inclination angle when the drag adjuster is inclined. And

  According to this fishing spinning reel, the inclination angle of the waterproof seal member when the drag adjusting body is screwed onto the spool shaft is smaller than the inclination angle when the drag adjusting body is inclined. Therefore, when removing the drag adjuster, the inclination angle becomes large, and accordingly, the locked state is maintained relatively long in the removal direction. In addition, when the drag adjuster is attached, the tip peripheral portion is easy to get over the locking projection due to the small inclination angle, and the locking state by pressing is relatively short.

Further, according to the present invention, when the waterproof seal member is attached by screwing the drag adjusting body to the spool shaft, the distal end peripheral portion contacts the locking protrusion that moves in the tightening direction of the drag adjusting body. The drag adjusting body is further tightened in the tightening direction from the position where the locking protrusion is in contact with the distal end peripheral portion, and the distal end peripheral portion is the movement length of the drag adjuster position to which as overcome the locking protrusion locked state is released and L _4, when the waterproof seal member is inclined to the mounting direction of the drag regulation member the length of the portion to be inclinable in the waterproof seal member and L _21, the inclination angle of the portion of the inclined movable when the waterproof sealing member is inclined to the mounting direction of the drag adjuster and theta _2, the locking The projection height from the opposing surface of the other side when the _{L 3} in the section, and satisfies the _{sinθ 2 = L 4 / L 21} , L 3 <L 21 (1-cosθ 2) .

  According to this fishing spinning reel, by satisfying the above formula, the waterproof seal member is inclined in the mounting direction by the tip peripheral portion being pressed by the locking projection that moves in the drag adjusting body mounting direction. Then, the drag adjusting body is further tightened, so that the tip peripheral portion gets over the locking projection and the pressed state is released.

According to the present invention, the waterproof seal member can ensure the sealing performance between the spool and the drag adjuster while allowing the drag adjuster to move, so that the brake member constituting the drag mechanism can be protected against dust and water. Can be planned.
In addition, even after the screw adjustment body starts to be released, the drag adjustment body can be locked to the spool by the action of elastic force via the waterproof seal member. Can be prevented. As a result, the drag adjusting body is not accidentally dropped, and handling at the time of spool replacement or the like is facilitated.
In addition, since the drag adjusting body can be removed from the spool by releasing the locking state between the distal end peripheral portion and the locking protrusion, while being configured to suitably prevent the drag adjusting body from falling off, The spool can be easily replaced and maintained.

  Further, in the configuration in which the waterproof seal member protrudes from the spool side toward the drag adjuster side, the length of the sliding contact portion is longer than when the waterproof seal member protrudes from the drag adjuster side toward the spool side. Since the length (circumferential length) can be shortened, the resistance generated through the waterproof seal member when the spool rotates through the drag mechanism can be reduced as much as possible by pulling fish, etc. The fishing line can be fed smoothly. Therefore, the rotational feeling of the spool via the drag mechanism is improved.

Moreover, than can be screwed length Ln of the spool shaft and the drag regulation member, it is longer length L ₁ from the abutment position of the tip circumferential portion of the opposing surface of the other side to the locking projection structure Then, in the state where the drag adjusting body is loosened and the screwed state starts to be released, the tip peripheral portion of the waterproof seal member can be positioned on the opposite surface on the other side, so that the drag adjusting body can be securely removed. Can be prevented.
Then, Ln <in the range satisfying the L _1, since the waterproof sealing member after releasing the screwed state is be engaged with the engaging projection without inclination, in a state where the waterproof seal member is inclined Compared with the case of being locked to the locking protrusion, the height of the protrusion of the locking protrusion from the opposite surface can be lowered, and the degree of freedom in design is increased.

Further, in the configuration satisfying all the above-described formulas, Ln> L ₁ , sin θ ₁ = (Ln−L ₁ ) / L ₂ , L ₃ > L ₂ (1−cos θ ₁ ), the tip peripheral portion of the waterproof seal member In this state, the lock protrusion is locked to the locking protrusion, and the drop adjuster can be suitably prevented from falling off.
In addition, since the locked state between the tip peripheral portion and the locking protrusion is maintained in an inclined state, the degree of freedom in designing each dimension around the spool is increased.
Furthermore, the waterproof sealing member, since the tip circumferential portion while inclined is adapted to be engaged with the engaging protrusion, it is possible to shorten the length L ₁ described above as much as possible, that amount In addition, the number of braking plates and lining materials of the braking member constituting the drag mechanism can be increased. As a result, a fishing spinning reel that can cope with higher performance of the drag mechanism can be obtained.

  Further, in the configuration in which the holding means is provided on at least one of the front end peripheral portion and the locking projection, the locking state between the spool and the drag adjusting body is easily maintained, so that the drag adjusting body is more preferably dropped off. Can be prevented.

  Further, in the configuration in which the inclination angle of the waterproof seal member when screwing and attaching the drag adjusting body to the spool shaft is set to be smaller than the inclination angle when inclining when removing the drag adjusting body. Since the locking state when removing the drag adjusting body is maintained for a relatively long time, the drag adjusting body can be suitably prevented from falling off, and the locking state by pressing when the drag adjusting body is attached Since it becomes comparatively short, the drag adjusting body can be attached smoothly.

Further, in the configuration satisfying the above-described equations, sin θ ₂ = L ₄ / L ₂₁ , L ₃ <L ₂₁ (1-cos θ ₂ ), the distal end peripheral portion of the waterproof seal member moves in the direction in which the drag adjuster is attached. Since it is pressed by the locking projection to be inclined in the mounting direction, and the drag adjusting body is further tightened, the tip peripheral portion gets over the locking projection and the pressed state is released. When the drag adjuster is attached, the pressed state between the tip peripheral portion and the locking projection can be reliably released, and the drag adjuster can be attached smoothly.

  Hereinafter, embodiments of a spinning reel for fishing according to the present invention will be described with reference to the drawings. In each embodiment, the same parts are denoted by the same reference numerals, and redundant description is omitted. In the following description, when referring to “front and back”, the direction shown in FIG. 1 is used as a reference.

(First embodiment)
As shown in FIG. 1, a fishing spinning reel mainly includes a reel body 1 in which legs 1 </ b> A for mounting on a fishing rod (not shown) and a rotor 2 rotatably provided in front of the reel body 1. And a spool 3 provided so as to be movable in the front-rear direction in synchronization with the rotational motion of the rotor 2.

  A handle shaft 4 is rotatably supported on the reel body 1 via a bearing (not shown), and a handle 5 that is wound up is attached to a protruding end (not shown). A shaft cylinder (not shown) is fixed to the handle shaft 4 so as not to rotate. The shaft cylinder is integrally formed with a drive gear 6 in which internal teeth for winding and driving the rotor 2 are formed. The drive gear 6 meshes with a pinion gear 8a of a drive shaft cylinder 8 that extends in a direction orthogonal to the handle shaft 4 and has a hollow portion extending in the axial direction inside.

  The drive shaft cylinder 8 is rotatably supported via a bearing, and a spool shaft 9 extending in a direction orthogonal to the handle shaft 4 and having the spool 3 attached to the distal end side is axially disposed in the hollow portion thereof. Is movably inserted and supported.

  An oscillating mechanism for moving the spool shaft 9 back and forth is provided at the rear end portion of the spool shaft 9. The oscillating mechanism includes at least an eccentric protrusion 7a provided on the interlocking gear 6b meshing with the gear 6a of the drive gear 6, a slider 7 attached to the rear end portion of the spool shaft 9, and the sliding A guide groove 7b that is provided in the child 7 and engages with the eccentric protrusion 7a, and a guide (not shown) that engages with the slider 7 and guides the reciprocation of the slider 7 is configured. Yes.

  The drive shaft cylinder 8 extends toward the spool 3 side, and the rotor 2 is attached to the front end portion of the drive shaft cylinder 8 via a nut 2a. In addition, a rolling one-way clutch (not shown) is attached to the intermediate portion of the drive shaft cylinder 8, and the one-way clutch is operated by rotating the switching member 1 c attached to the outside of the reel body 1. Is switched between an operating state and a non-operating state. In this case, the rotation of the handle 5 (rotor 2) in the reverse direction (rotation in the direction of releasing the fishing line) is prevented by switching the switching member 1c to the operating state.

  The rotor 2 includes a cylindrical portion 2b positioned in the skirt portion 3a of the spool 3 and a pair of arm portions 2c and 2d. Bail support members 2e and 2f are supported at the front ends of the respective arm portions 2c and 2d so as to be rotatable between a fishing line winding position and a fishing line discharge position, and between these bale support members 2e and 2f. Is provided with a bale 2g for picking up the fishing line in the released state. The bail 2g has one base end attached to a fishing line guide (not shown) provided integrally with the bail support member 2e, and the other base end attached to the bail support member 2f.

  The spool 3 includes a fishing line winding body portion 3c around which a fishing line (not shown) is wound between the skirt portion 3a and the front flange 3b, and is frictionally coupled to the spool shaft 9 via a braking member 10 that forms a drag mechanism. Then, the drag force of the spool 3 is adjusted by rotating the drag adjusting body 20 that forms a drag mechanism that is screwed onto the tip of the spool shaft 9.

  The drag mechanism applies a desired braking force to the spool 3 rotatably supported by the spool shaft 9, that is, a desired braking force to the spool 3 when the fishing line wound around the spool 3 is fed out. The brake member 10 and the drag adjusting body 20 are provided.

As shown in FIG. 1 (b), the braking member 10 is accommodated in an accommodation chamber 3 d formed by being partitioned by a cylindrical partition wall 3 h provided inside the spool 3. On the other hand, it has two brake plates 11a and 11c that can move in the axial direction and are fitted to prevent rotation, and a protrusion that is engaged with a groove 3e provided on the inner surface of the storage chamber 3d. Each of the brake plates 11b, and between the brake plates 11a and 11b, between the brake plates 11b and 11c, and on the side of the brake plate 11c, are provided with three lining materials 12 respectively.
When the drag adjusting body 20 is tightened, the braking member 10 composed of these members is a spool-side member due to the urging force of the drag spring 23 caused by the sliding of the pressing member 25 described later, as shown in FIG. 21 is pressed by the rear surface 21 d ′ and pressed against the front end surface 3 f of the spool 3. Thereby, a desired drag force is generated on the spool 3.

A waterproof seal member 30 that is elastically deformable is attached to the opening of the accommodation chamber 3d. The waterproof seal member 30 is an annular member made of a material such as synthetic rubber (for example, butylene rubber), and protrudes from the spool 3 side toward the drag adjuster 20 side. The spool 3 and the drag adjuster 20 (spool A space formed between the side member 21 and the body portion 21 b) is closed in the axial direction of the spool shaft 9.
The waterproof seal member 30 includes a mounting portion 31 having a substantially U-shaped cross section attached to the front end opening of the storage chamber 3d, and a disk-shaped movable portion 32 provided integrally with the mounting portion 31. The tip peripheral portion 33 (inner peripheral portion) is slidably contacted with the entire circumferential direction of the outer peripheral surface 21c of the body portion 21b serving as the opposing surface.

  The attachment part 31 is formed thicker than the movable part 32, and includes a fitting part 31a that fits in a circumferential groove 3g formed in the front end peripheral part of the partition wall 3h. The movable portion 32 is formed thinner than the mounting portion 31 and extends so as to be orthogonal to the spool shaft 9. The spool side member 21 of the drag adjusting body 20 is positioned on the inner peripheral side of the movable portion 32, and the distal end peripheral portion 33 of the movable portion 32 is circumferentially formed on the outer peripheral surface 21c of the trunk portion 21b. It comes into contact with elasticity.

As will be described later, the movable portion 32 has a front end peripheral portion 33 projecting from the rear end portion of the outer peripheral surface 21c when the drag adjuster 20 is loosened and the drag adjuster 20 is removed from the spool shaft 9. It is configured to be detachably locked to the stop protrusion 24, and in the locked state, it can be inclined toward the direction of removing the drag adjusting body 20 (front of the spool 3) (FIG. 3A ) (B)).
That is, when the tightening of the drag adjusting body 20 is loosened and the screw adjusting state of the drag adjusting body 20 is released, the locking projection 24 is brought into contact with and locked with the distal end peripheral portion 33 of the waterproof seal member 30, and FIG. ), The distal end peripheral portion 33 is pulled by the locking projection 24 that moves in the removal direction, and tilts while maintaining the locked state in the removal direction of the drag adjuster 20. Therefore, the drag adjusting body 20 is held by the spool 3 via the waterproof seal member 30 even after the screw adjusting state of the drag adjusting body 20 and the spool shaft 9 is released.

Further, as will be described later, when the drag adjusting body 20 is screwed and attached to the spool shaft 9, the movable portion 32 has a tip peripheral portion 33 formed by a locking protrusion 24 that moves in the attaching direction of the drag adjusting body 20. By being pressed, it is possible to incline toward the attachment direction of the drag adjuster 20 (see FIGS. 4A and 4B).
That is, when the drag adjusting body 20 is tightened, the locking projection 24 comes into contact with the distal end peripheral portion 33 of the waterproof seal member 30 and the locking projection 24 moves in the mounting direction. ), The distal end peripheral portion 33 is pressed, and the movable portion 32 is inclined in a substantially conical shape in the attachment direction of the drag adjusting body 20. When the drag adjusting body 20 is further tightened, the distal end peripheral portion 33 gets over the locking projection 24 and the pressing state (locking state) between the distal end peripheral portion 33 and the locking projection 24 is released. It will be.
Details of the inclination of the movable portion 32 will be described later.

Here, as shown in FIG. 2B, the waterproof seal member 30 is formed with a step 32 a on the front side to form a boundary portion between the attachment portion 31 and the movable portion 32. In this embodiment, since the step 32a is formed in a rounded shape, stress is not concentrated on this portion, and a suitable substantially conical inclination of the movable portion 32 is realized.
Further, since the step 32a is formed in a round shape, when the movable portion 32 is inclined in a substantially conical shape (bent) toward the direction of removing the drag adjusting body 20 (front of the spool), the bent portion is separated from the partition wall. It acts so as to press against the tip end side of 3h, and the bent portion (attachment portion 31) is prevented from fluttering.
The position where the step 32a is formed can be arbitrarily set in the radial direction of the waterproof seal member 30, and the length of the movable part 32 (the length of the bending) can be changed by changing the bending position. it can.
In the present embodiment, the length L ₂ of the movable portion 32 in the removing direction of the drag regulation member 20 is inclined, the length L ₂₁ and have the same length of the movable portion 32 in the mounting direction is inclined (L 2 ₌ L ₂₁ ) (See FIGS. 3A and 3B and FIGS. 4A and 4B).

  Referring to FIG. 1B, the drag adjusting body 20 adjusts the strength of the drag force that brakes the rotation of the spool 3 and also prevents the spool 3 from coming off while being screwed to the spool shaft 9.

And an operation member 22.

  The spool-side member 21 has a substantially hat-shaped cross section with a hollow portion 21a that opens to the front side, and a drag spring 23 is accommodated in the hollow portion 21a. An insertion hole 21e through which the spool shaft 9 is inserted is formed in the rear portion 21d of the spool side member 21, and the spool side member 21 is inserted in the axial direction with respect to the spool shaft 9 through the insertion hole 21e. It is movable and has a non-rotating fit. Then, in a state in which the drag adjusting body 20 is attached and tightened to the spool shaft 9 (see FIG. 2A), the rear portion 21d of the spool side member 21 is disposed in the accommodation chamber 3d, and the rear surface 21d ′ The brake plate 11a of the brake member 10 is pressed. In this state, the distal end peripheral portion 33 of the waterproof seal member 30 is in contact with the outer peripheral surface 21c of the cylindrical body portion 21b of the spool-side member 21 (so as to be slidable).

  As shown in FIG. 2B, a locking projection 24 having a substantially hemispherical cross section is projected from the outer peripheral surface 21c toward the spool 3 on the outer peripheral portion of the rear end of the body portion 21b. When the drag adjusting body 20 is attached or removed, the front end peripheral portion 33 of the waterproof seal member 30 is detachably locked to the locking protrusion 24. Details of the locking between the locking protrusion 24 and the tip peripheral portion 33 will be described later.

Referring to FIG. 1B, the adjustment operation member 22 includes an operation part (a knob part) 22 a that is formed to project in a bank shape, and is attached and fixed to the front side of the spool side member 21. The adjusting operation member 22 has a concave portion 22b communicating with the hollow portion 21a of the spool side member 21 on the rear side, and the concave portion 22b is screwed into a male screw portion 9a formed at the tip end portion of the spool shaft 9. A cylindrical pressing member 25 having a matable female thread portion 25a is disposed. A front end portion of the drag spring 23 is brought into contact with the rear surface of the pressing member 25 with an urging force.
In the present embodiment, the recess 22b is a hollow square hole such as a hexagon, and the pressing member 25 is configured to have an outer shape corresponding to the hollow square hole and moves in the axial direction with respect to the recess 22b. It is possible and is arranged with a non-rotating fit.
Accordingly, when the adjustment operation member 22 is rotated, the pressing member 25 moves in the recess 22b as shown in FIG. 2A while rotating along the spool shaft 9, and the movement Accordingly, the urging force of the drag spring 23 is adjusted to give a desired braking force to the braking member 10.

Next, the relationship between the waterproof seal member 30 and the locking projection 24 of the drag adjuster 20 will be described.
In the present embodiment, the length that can be screwed between the spool shaft 9 and the pressing member 25 of the drag adjusting body 20 is Ln (see FIG. 1A), and the drag adjusting body 20 is tightened to the maximum (substantially). The drag adjusting body 20 (spool side member 21) is moved from a position where the drag adjusting body 20 is tightened so that the maximum drag force can be obtained to a position where the locking protrusion 24 comes into contact with the tip peripheral portion 33. When the moving length is L ₁ (see FIG. 2B), Ln> L ₁ is set.
That is, when the tightening of the drag adjusting body 20 is loosened, the engagement protrusion 24 is fixed to the distal end peripheral portion 33 before the screwing of the female screw portion 25a of the pressing member 25 and the male screw portion 9a of the spool shaft 9 is released. Are set so as to contact each other. Therefore, when the screwing of the pressing member 25 and the spool shaft 9 starts to be released, the movable portion 32 of the waterproof seal member 30 is inclined in the direction in which the drag adjusting body 20 is removed.

Therefore, in this embodiment, the relationship between the respective parts is as follows so that the distal end peripheral portion 33 is locked to the locking protrusion 24 in a state where the screwing of the pressing member 25 and the spool shaft 9 starts to be released. It is set as follows.
That is, as shown in FIG. 3B, the length of the movable portion 32 that is a portion that can be tilted and moved in the waterproof seal member 30 is L _2, and the movable portion 32 of the waterproof seal member 30 is in the direction of removing the drag adjuster 20. The inclination angle at the time of inclination is θ ₁ , the protrusion height from the outer peripheral surface 21 c of the locking projection 24 is L _3, and the height when the tip peripheral portion 33 is locked to the locking projection 24 is high. When the thickness is La, the following formulas (1) to (3) are satisfied.
_{La = L 2 -L 2 cosθ 1} = L 2 (1-cosθ 1) ··· (1)
sin θ ₁ = (Ln−L ₁ ) / L ₂ (2)
L ₃ > L ₂ (1-cos θ ₁ ) (3)
Where 0 ° <θ ₁ <45 °

In other words, the height La of when tip circumferential portion 33 is engaged with the locking projections 24, which are set to be smaller than the protrusion height L ₃ of the locking projection 24, the pressing member When the screwing of the spool 25 and the spool shaft 9 starts to be released, the locking state between the locking protrusion 24 and the tip peripheral portion 33 is maintained, and the drag adjusting body 20 is reliably attached to the spool 3. It is supposed to be retained.

  When the drag adjusting body 20 is further pulled in the removal direction from this state, the locking projection 24 further moves in the removal direction, and the tip peripheral portion 33 gets over the locking projection 24, and these locking states are The drag adjusting body 20 can be removed. As a result, the spool 3 can be removed.

On the other hand, when the drag adjusting body 20 is tightened, as described above, Ln> L ₁ is set, so that the locking projection 24 contacts the tip peripheral portion 33 during the tightening. By contacting and further tightening, the locking projection 24 presses the distal end peripheral portion 33, and the movable portion 32 of the waterproof seal member 30 is inclined in the attachment direction of the drag adjusting body 20.
Therefore, when the drag adjusting body 20 moves to a position where it is tightened to the maximum (preferably, when the rear surface 21d ′ of the spool side member 21 of the drag adjusting body 20 moves to a position where it abuts against the braking member 10), It is necessary to disengage the tip peripheral portion 33 from the stop projection 24. For this reason, in the present embodiment, the relationship between each part is set as follows.

That is, as shown in FIG. 4B, the inclination angle when the movable portion 32 of the waterproof seal member 30 is inclined in the removal direction of the drag adjuster 20 is θ ₂ , and the tip peripheral portion 33 is the locking projection 24. Is set so as to satisfy the following expressions (4) to (6), where La ′ is the height at which the moving part 32 is tilted in the attachment direction of the drag adjuster 20 and L ₂₁ is the length at which the movable part 32 is inclined. is doing. In the present embodiment, as described above, since the length L ₂₁ and the length L ₂ of inclination of the movable portion 32 are of the same length, it is described by replacing the length L ₂₁ to the length L ₂ .
La ′ = L ₂ −L ₂ cos θ ₂ = L ₂ (1-cos θ ₂ ) (4)
sin θ ₂ = L ₄ / L ₂ (5)
L ₃ <L ₂ (1-cos θ ₂ ) (6)

In other words, the height La 'when the tip circumferential portion 33 is disengaged from the locking projection 24, so that is greater than the protrusion height L ₃ of the locking projection 24, tightening the drag regulation member 20 in a substantially maximum In this position, the engagement state (pressed state) between the locking projection 24 and the tip peripheral portion 33 is reliably released, and the tip peripheral portion 33 gets over the locking projection 24 and the movable portion 32 is inclined. The state is released.
As a result, the distal end peripheral portion 33 comes into contact with the outer peripheral surface 21c of the body portion 21b of the spool side member 21, and the space between the spool 3 and the drag adjusting body 20 is closed by the waterproof seal member 30 (FIG. 2 ( a)).

According to the fishing spinning reel of the present embodiment described above, the waterproof seal member 30 that can be elastically deformed is projected so as to close the space formed between the spool 3 and the drag adjuster 20, Since the tip peripheral portion 33 is configured to be in sliding contact with the outer peripheral surface 21c of the body portion 21b of the spool side member 21 of the drag adjusting body 20, the spool 3 and the drag adjusting body can be moved while allowing the drag adjusting body 20 to move. The sealing performance between the brake member 10 and the brake member 10 constituting the drag mechanism can be ensured.
Furthermore, since the distal end peripheral portion 33 of the waterproof seal member 30 is releasably locked to the locking protrusion 24 in a state where the drag adjustment body 20 is released from the spool shaft 9, the drag adjustment body 20 is engaged. Even after the screwing is released, the drag adjusting body 20 can be locked to the spool 3 by the action of elastic force, and the brake member 10 can be continuously protected from dust and water.

In addition, since the drag adjusting body 20 can be locked to the spool 3 through the waterproof seal member 30 even after the drag adjusting body 20 is unscrewed, the drag adjusting body 20 is preferably prevented from falling off. can do. As a result, the drag adjusting body 20 is not accidentally dropped, and handling such as when the spool 3 is replaced becomes easy.
Moreover, since the drag adjusting body 20 can be removed from the spool 3 by releasing the locking state between the distal end peripheral portion 33 and the locking protrusion 24, it is possible to suitably prevent the drag adjusting body 20 from falling off. Although it is configured, replacement and maintenance of the spool 3 can be easily performed.

Moreover, since the inner peripheral part used as the front-end | tip peripheral part 33 of the waterproof seal member 30 will be slidably contacted with the outer peripheral surface 21c used as the opposing surface of the drag adjustment body 20, on the contrary, it is spooled from the drag adjustment body 20 side. Compared to the case where the waterproof seal member 30 protrudes toward the side 3 and the outer peripheral portion that is the tip peripheral portion is in sliding contact with the opposing surface of the spool 3, the length of the sliding contact portion (circumferential length) ) Can be shortened.
Therefore, the resistance generated through the waterproof seal member 30 when the spool 3 rotates through the drag mechanism can be made as small as possible, and the fishing line can be fed out smoothly by pulling fish or the like. Therefore, the rotational feeling of the spool 3 through the drag mechanism is improved.

In addition, by satisfying the expressions (1) to (3), the waterproof seal member 30 has the tip peripheral portion 33 engaged with the locking projection in a state where the screw engagement between the spool shaft 9 and the drag adjusting body 20 is released. The drag adjusting body 20 is tilted in the removal direction while maintaining the state of being locked to the portion 24, and the drag adjusting body 20 is held by the spool 3. Therefore, the drag adjusting body 20 is preferably prevented from falling off. can do.
In addition, since the locked state between the tip peripheral portion 33 and the locking projection 24 is maintained in an inclined state, the degree of freedom in designing each dimension around the spool 3 is increased.
Furthermore, the waterproof sealing member 30, since the tip circumferential portion 33 is adapted to be engaged with the locking projection 24 while inclined, it is possible to shorten the length L ₁ described above as much as possible Accordingly, the number of braking plates 11a to 11c and lining material 12 of the braking member 10 constituting the drag mechanism can be increased. As a result, a fishing spinning reel that can cope with higher performance of the drag mechanism can be obtained.

  Moreover, by satisfy | filling said Formula (4)-(6), it will be in the state which the front-end | tip peripheral part 33 of the waterproof seal member 30 is pressed and inclined by the latching protrusion 24 which moves to the attachment direction of the drag adjustment body 20. Further, the drag adjusting body 20 is further tightened, so that the distal end peripheral portion 33 gets over the locking projection 24 and the pressing state is released. Therefore, when the drag adjusting body 20 is attached, the distal end peripheral portion 33 is locked. The pressing state with the protrusion 24 can be reliably released. Thereby, the drag adjuster 20 can be attached smoothly.

(Second Embodiment)
This embodiment is different from the first embodiment in that a holding means is provided on the distal end peripheral portion 33 of the waterproof seal member 30.
As shown in FIGS. 5A and 5B, the tip peripheral portion 33 of the waterproof seal member 30 is formed with a projection 33a that functions as a holding means on the rear side that is in contact with the locking projection 24a. ing. The protrusion 33a has a semi-spherical cross section, and as shown in FIG. 5B, the protrusion 33a has a shape that is easily hooked to the opposing surface 24b of the locking protrusion 24a and is easily maintained in a locked state. . Moreover, the opposing surface 24b of the latching protrusion 24a is formed flat, and the protrusion 33a is easily caught compared with the latching protrusion 24 shown in 1st Embodiment.

  Further, the front portion 33b of the distal end peripheral portion 33 is chamfered in a round shape so that the locked state with the locking projection 24a is easily released. Further, the locking projection 24a has a rear portion 24c that continues from the facing surface 24b and is chamfered in a rounded shape so that the locking state with the front portion 33b of the distal end peripheral portion 33 is easily released.

Even in the spinning reel for fishing having such a configuration, when the drag adjusting body 20 is loosened and the drag adjusting body 20 is removed, the opposing surface 24b of the locking projection 24a is the peripheral edge of the waterproof seal member 30. The protrusion 33a of the portion 33 is abutted and locked. Here, the protrusion 33a is formed in a hemispherical shape, and the opposing surface 24b of the locking protrusion 24a is formed flat, so that when the drag adjuster 20 is removed, they are easily caught with each other. .
Therefore, compared with the case where such a protrusion 33a and the opposed surface 24b are not formed, the locked state between them is suitably maintained, and the drag adjusting body 20 is more preferably dropped off. Can be prevented.

Further, when the drag adjusting body 20 is screwed onto the spool shaft 9 and the drag adjusting body 20 is attached, the rear portion 24c of the locking projection 24a abuts against and presses the front portion 33b of the distal end peripheral portion 33. Therefore, like the first embodiment, the movable portion 32 of the waterproof seal member 30 is inclined in a substantially conical shape in the attachment direction of the drag adjusting body 20, but the opposing surfaces at the time of pressing are formed in a round shape. Therefore, the tip peripheral portion 33 can easily get over the locking projection 24a.
Therefore, compared with the case where the opposing surfaces at the time of pressing are not formed in a round shape as described above, the locking state between the locking protrusion 24a and the tip peripheral portion 33 is easily released, and the drag adjusting body 20 Smooth installation is realized.

Further, as described above, the locking state of the locking protrusion 24a and the tip peripheral portion 33 is easily maintained in the direction of removing the drag adjusting body 20, and the drag adjusting body 20 on the opposite side is attached. Since the locking state between the locking protrusion 24a and the tip peripheral portion 33 is easily released in the direction, as shown in FIG. 5 (b), the inclination in the removal direction is inclined compared to that shown in the first embodiment. The angle θ ₃ and the inclination angle θ ₄ in the mounting direction can be made different, thereby increasing the degree of freedom in designing each part.

(Third embodiment)
This embodiment is different from the first and second embodiments in that the length (bending length) of the movable portion 32 that is the movable portion of the waterproof seal member 30 is different from the removal direction and the attachment direction of the drag adjuster 20. The difference is that they are provided differently.

As a configuration for this purpose, in the present embodiment, an abutting portion 34 for changing the bending position of the movable portion 32 is provided inside the front end of the partition wall 3h of the spool 3.
By providing such a contact portion 34, than the length L ₂ of the movable portion 32 when the drag adjusting member 20 is inclined toward the removal direction, when inclined in the direction fitted with the drag regulation member 20 The length L ₂ ′ of the movable portion 32 becomes shorter.

That is, in such a configuration as to fish spinning reel fishing, when removing the drag regulation member 20 by loosening the tightening of the drag regulation member 20, substantially conical movable portion 32 in the removal direction includes a length L ₂ Jo to become inclined, the locking state is realized between the locking projection 24 and the tip peripheral portion 33 by effectively utilizing the length L _2. Accordingly, it is possible to suitably prevent the drag adjuster 20 from falling off.

On the other hand, when the drag adjusting body 20 is attached, the movable portion 32 comes into contact with the contact portion 34 and has a length L ₂ ′ shorter than the length L ₂ described above, and the movable portion 32 is substantially conical in the attachment direction. The rotation radius at the time of inclination becomes small, and the pressing state of the locking projection 24 and the tip peripheral portion 33 is easily released.
Therefore, compared to the example shown in the first embodiment, the distal end peripheral portion 33 can easily get over the locking projection 24 and the smooth attachment of the drag adjusting body 20 can be realized.

(Fourth embodiment)
The difference between the present embodiment and the first to third embodiments is that a waterproof seal member 30A protrudes from the drag adjuster 20 side toward the spool 3, and is opposed to the distal end peripheral portion (outer peripheral portion) 33A. The point is that the tip peripheral portion 33A is in sliding contact with the inner peripheral surface 35 of the spool 3 serving as a surface.
In FIG. 7B, for simplicity, the spool 3 side is shown to move relative to the drag adjuster 20.

Waterproof seal member 30A is attached portion 31A is attached to the outer peripheral surface 21c of the body portion 21b of the spool-side member 21, the movable portion 32A is a length _{L 7,} when removing the drag regulation member 20, The distal end peripheral portion 33A is locked to the locking projection 36, and is inclined in a substantially conical shape in a direction opposite to the direction in which the drag adjusting body 20 is removed.
Further, the movable portion 32A is inclined in the same manner as the direction opposite to the direction in which the drag adjusting body 20 is attached, with the tip peripheral portion 33A coming into contact with the locking projection 36 when the drag adjusting body 20 is attached. Yes.

When the drag adjuster 20 is attached, a portion of the cylindrical portion of the adjustment operation member 22 that is in the radial direction from the central portion of the movable portion 32A comes into contact with the rear end portion 22c. Irregularly, the movable part 32A bends and tilts. At this time, since the length L ₇ ′ of the movable portion 32A, which is irregularly bent, is shorter than the length L _{7, the} radius of rotation at the time of inclination becomes small, and the pressed state is easily released.
Therefore, compared with the case where such irregular bending does not occur, in this embodiment, the pressing state between the locking projection 24 and the tip peripheral portion 33A is easily released, and the drag adjusting body 20 can be smoothly attached. Can be realized.

FIG. 8 is a view showing a modification of the fishing spinning reel of this embodiment. As shown in FIG. 8, in this modification, the braking member 10 is composed of a pair of braking plates 11a and a lining material 12, and the trunk portion 21b of the spool-side member 21 is correspondingly longer toward the braking member 10 side. It is extended.
In this fishing spinning reel, when the drag adjusting body 20 is screwed to the spool shaft 9, the length that can be screwed between the spool shaft 9 and the drag adjusting body 20 is Ln, and the body portion of the spool side member 21. from the contact position of the tip circumferential portion 33 on the outer peripheral surface 21c and 21b to a length of the locking projection 24 when the L _1, are set so that Ln <L _1.

In other words, in this fishing spinning reel, Ln <L ₁ is set as described above. Therefore, in the state where the drag adjusting body 20 is loosened and the screwing state starts to be released, the waterproof seal member 30 The tip peripheral portion 33 can be positioned on the outer peripheral surface 21c.
Therefore, the drag adjuster 20 can be reliably prevented from falling off.

Then, Ln <in the range satisfying the L _1, since the waterproof seal member 30 after releasing the screwed state is be engaged with the engaging projection 24 without tilting, waterproof seal member 30 is inclined Compared to the case where the locking protrusion 24 is locked in this state, the protrusion height of the locking protrusion 24 from the outer peripheral surface 21c can be lowered, and the degree of freedom in design is increased.

Incidentally, in the first embodiment has been set such that the movable portion 32 of the waterproof seal member 30 becomes the length L ₂ in either direction of the removal direction and the mounting direction of the drag regulation member 20, limited to It can be set as different lengths as appropriate. For example, the formation position of the step 32 a may be moved in the radial direction of the waterproof seal member 30 so that the bent position is different before and after the waterproof seal member 30.

  Moreover, in the said 1st-3rd embodiment, although the attaching part 31 of the waterproof seal member 30 was fixed to the partition wall 3h of the spool 3, it is not restricted to this, The inner peripheral surface 35 (FIG. 7) of a spool 3 The front peripheral portion 33 may be extended toward the outer peripheral surface 21c of the barrel portion 21b of the spool side member 21 of the drag adjusting body 20 by fixing the attachment portion 31 to the reference portion).
