DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag adjusting mechanism and, more particularly, to adjusting a braking force of a drag mechanism for braking the rotation of a spool rotatably mounted on a reel body of a dual-bearing reel in a line payout direction. And a drag adjusting mechanism for a dual bearing reel.

[0002]

2. Description of the Related Art A dual-bearing reel is provided with a drag mechanism for braking the rotation of a spool in a line payout direction to prevent the fishing line from being cut by a sharp strong pull. As a drag mechanism, a star drag type disposed around a handle shaft and a lever drag type disposed around a spool shaft are known. In the case of the star drag type, the braking force (drag force) is adjusted by a star drag as a drag adjusting member that is rotatably disposed on the distal end side of the handle shaft by being screwed to the handle shaft. In the case of the lever drag type, the drag force is adjusted by a drag lever as a drag adjusting member mounted so as to swing around the spool shaft.

[0003] The star drag type drag mechanism has a plurality of drag discs pressed by the star drag. The drag disc presses a main gear rotatably mounted on the handle shaft. The main gear meshes with a pinion gear that rotates in conjunction with the spool, and presses the main gear to brake the rotation of the spool in the line payout direction. In such a star drag type drag mechanism, the pressing force on the drag disk, that is, the drag force can be adjusted by rotating the star drag and moving it in the handle axis direction.

The lever-drag type drag mechanism has a moving mechanism for converting the swing of the drag lever into an axial movement of the spool shaft, and a drag disk which is moved in the spool axial direction by the moving mechanism. The moving mechanism has a cam mechanism arranged between the reel body and the drag lever, and converts the swing of the drag lever into an axial movement of the spool shaft. In such a lever-drag type drag mechanism, when the drag lever is swung, the cam mechanism moves the spool shaft in the axial direction and the drag disk moves in the same direction to adjust the drag force.

In either type of drag mechanism, the amount of operation of the drag adjustment member and the amount of movement of the drag adjustment member or the amount of movement of the spool shaft are substantially proportional. The maximum drag force is set to be about 1.5 times the normal drag force.

On the other hand, there is known a dual-bearing reel having such a structure, in which a spool lock mechanism is provided separately from a drag mechanism in order to collect a device when the device is stuck. A conventional spool lock mechanism of a dual-bearing reel includes a rotating member that is non-rotatably mounted on a spool shaft, a lock member that is movably mounted in a radial direction of the rotating member, and locks the rotating member. And a moving mechanism for moving between them. The rotating member is
Usually, the outer peripheral portion has a plurality of teeth formed at intervals in the circumferential direction, and is fixed to the spool shaft by an appropriate fixing means such as serration connection. The lock member is mounted on the reel body so as to be movable in the radial direction of the rotating member between a contact position where the lock member contacts the tooth portion and a separation position where the lock member separates.

In the dual-bearing reel configured as above,
When the device is locked, the lock member is moved to the contact position by the moving mechanism, and the rotating member is locked. As a result, the rotation of the spool shaft is disabled, and the spool is locked so as not to rotate. Then, after winding the fishing line to remove the dandruff, the fishing rod is pulled straight toward the device. By doing so, the counterpart object, the hook, the fishing line, or the binding portion thereof that has been hung up are damaged, and the device or a part of the device can be collected.

[0008]

In the above-mentioned conventional configuration,
Since the spool lock mechanism for locking the spool is provided separately from the drag mechanism, a storage space for providing the spool lock mechanism is required. For this reason, it is difficult to reduce the size of the reel, and the weight may increase due to the provision of the spool lock mechanism and its storage space.

SUMMARY OF THE INVENTION It is an object of the present invention to make a spool close to a locked state while reducing the size and weight.

[0010]

A drag adjusting mechanism for a dual-bearing reel according to the first aspect of the present invention provides a braking force of a drag mechanism that brakes rotation of a spool rotatably mounted on a reel body of the dual-bearing reel in a line payout direction. , And includes a drag adjustment member and a conversion mechanism. The drag adjustment member is a member that rotates with respect to a spool shaft mounted on the reel body and adjusts the drag force of the drag mechanism by the rotation. The conversion mechanism converts the rotation of the drag adjustment member into movement in the spool axis direction of the drag mechanism, and moves the drag mechanism in the spool axis direction during rotation with respect to the rotation amount per unit of the drag adjustment member. It is a mechanism to increase the amount rapidly.

In this drag adjustment mechanism, when the drag adjustment member is rotated, the rotation is converted by the conversion mechanism into movement of the drag mechanism in the spool axis direction, and the drag mechanism moves in the spool axis direction. The amount of movement in the spool axis direction increases abruptly during rotation with respect to the amount of rotation per unit of the drag adjustment member, and the braking force of the drag mechanism sharply increases.
Here, since the amount of movement of the drag mechanism in the spool axial direction is rapidly increased during rotation with respect to the amount of rotation per unit of the drag adjustment member, the spool is locked by the drag mechanism without providing a spool lock mechanism. Can be approached. Therefore, a space for accommodating the spool lock mechanism is not required, and the weight increase due to the provision of the spool lock mechanism and the accommodation space does not occur, so that the spool can be brought closer to the locked state while reducing the size and weight. .

A drag adjusting mechanism for a dual bearing reel according to a second aspect of the present invention is the mechanism according to the first aspect, wherein the conversion mechanism presses the first cam provided on the drag adjusting member and the drag mechanism in the first axial direction. A second cam portion, which is provided so as to be engaged with the first cam portion and moves in the first axial direction by the rotation of the drag adjusting member, and biases the drag mechanism in a second axial direction opposite to the first axial direction. An urging member, and the second cam portion is largely moved during the rotation with respect to the rotation of the drag adjustment member. In this case, when the drag adjusting member is rotated in one direction, the first cam portion also rotates in the same direction, and the second cam portion engaged with the first cam portion moves in the first axial direction, and the drag mechanism is moved. Is pressed in the first axial direction. As a result, the braking force by the drag mechanism gradually increases. The second cam portion moves largely during the rotation of the drag adjustment member, and the pressing force on the drag mechanism increases dramatically. As a result, the braking force of the drag mechanism is dramatically increased, and the spool can be brought closer to the locked state. Here, by using the cam, the rotational movement can be easily converted into the movement in the spool axial direction, and the amount of movement in the spool axial direction can be easily varied depending on the shape of the cam.

A drag adjusting mechanism for a dual bearing reel according to a third aspect of the present invention is the drag adjusting mechanism according to the second aspect, wherein at least one of the first cam portion and the second cam portion has a first inclined surface, a first inclined surface, and a circumferential surface. And a second inclined surface formed continuously in the direction and having a greater inclination angle than the first inclined surface.
In this case, when the two cam portions are engaged on the first inclined surface, the braking force gradually increases, and when moving to the second inclined surface, the braking force increases rapidly. Here, the braking force can be easily increased rapidly only by changing the inclination angle of the inclined surface.

A drag adjusting mechanism for a dual-bearing reel according to a fourth aspect of the present invention is the mechanism according to the third aspect, wherein the tilt cam is the second
It has a flat surface following the inclined surface. In this case, the maximum drag state close to the locked state is stabilized even if the rotating state fluctuates when the two cam portions are engaged on the flat surface.

A drag adjusting mechanism for a dual bearing reel according to a fifth aspect of the present invention is the mechanism according to the fourth aspect, wherein the flat surface has a depression. In this case, by providing the depression, it is possible to obtain a click feeling that allows the user to recognize the maximum drag state.

A drag adjusting mechanism for a dual-bearing reel according to a sixth aspect of the invention is the mechanism according to any one of the third to fifth aspects, wherein
The second cam portion includes a pressing portion provided on the reel body so as to be movable in the spool axis direction so as to press the spool shaft in the first axial direction, and a first cam disposed on the spool portion along the radial direction of the spool shaft. And a plurality of cam pins that are provided so as to be able to contact the inclined cams of the section and are non-rotatably locked to the reel body. In this case, since the rotational movement is converted into the axial movement by the line contact between the cam pin and the inclined cam, the contact portion is reduced, the friction is reduced, and the converting operation is smooth.

A drag adjusting mechanism for a dual-bearing reel according to a seventh aspect of the present invention is the mechanism according to any one of the third to sixth aspects, wherein
The first inclined surface has a plurality of protrusions formed at intervals in the rotation direction of the drag adjustment member. In this case, a click feeling is obtained by the convex portion, and the operator can recognize the rotation position within the rotation range of the drag adjustment member, so that it is possible to prevent the operation from being erroneously brought into a state close to the drag lock state.

A drag adjusting mechanism for a dual-bearing reel according to an eighth aspect of the present invention is a mechanism for adjusting a braking force of a drag mechanism that brakes rotation of a spool rotatably mounted on a reel body of the dual-bearing reel in a line payout direction. And a drag adjusting member and a conversion mechanism. Drag adjustment member
A member that is rotatable with respect to a handle shaft rotatably mounted on the reel body and is capable of pressing the drag mechanism with a variable pressing force. The conversion mechanism is a mechanism that converts the rotation of the drag adjustment member into a movement in the axial direction of the handle shaft, and that abruptly changes the amount of movement in the axial direction during the rotation with respect to the amount of rotation per unit.

In this drag adjustment mechanism, when the drag adjustment member is rotated, the rotation is converted by the conversion mechanism into movement in the handle axis direction, and the drag mechanism is pressed. The amount of movement of the drag operation member in the handle axis direction rapidly increases during the rotation with respect to the amount of rotation of the drag adjustment member per unit. Here, since the amount of movement in the handle axis direction is suddenly increased during the rotation with respect to the amount of rotation per unit of the drag adjustment member, the spool can be brought closer to the locked state by the drag mechanism without providing the spool lock mechanism. Can be. Therefore, a space for accommodating the spool lock mechanism is not required, and the weight increase due to the provision of the spool lock mechanism and the accommodation space does not occur, so that the spool can be brought closer to the locked state while reducing the size and weight. .

The inner side surface of the side plate 10 is in contact with the left end of the outer ring. As shown in FIG. 3, the spool 3 is in contact with the left side of the outer ring of the right bearing 32 b supporting the spool 3. Four disc springs 34 are in contact with the right side of the inner ring via the washers 21. The disc spring 34 is provided with a drag operation lever 41.

Is in contact with

The spool 3 includes a bobbin trunk 3a and a bobbin trunk 3
a at both ends and a flange portion 3b integrally formed. A brake disc 35 of the lever drag mechanism 7 is mounted outside the flange 3b on the left side in FIG. In order to attach a cover member 39 for covering the braking disk 35, the outer peripheral portion of the left flange portion 3b
A cylindrical portion 3d extending outward in the spool axial direction is formed. The inner peripheral surface 3e of the cylindrical portion 3d is undercut and subjected to meat stealing. As a result, the weight of the spool 3 is reduced, and the inertia of the spool 3 is reduced.

The rotation of the handle 4 is transmitted to the spool shaft 2 via the handle shaft 5, main gear 16, and pinion gear 17.

[Structure of Lever Drag Mechanism] As shown in FIG. 1, the lever drag mechanism 7 has a brake disk 35 mounted on the outer surface of the flange 3b on the left side of FIG.
And a friction disc 36 arranged so as to be able to contact the braking disc 35. The drag force of the lever drag mechanism 7 is adjusted between a drag release state and a technique drag lock state by a drag adjustment mechanism 8 for reciprocating the spool 3 and the friction disk 36 in the spool axial direction. Individually, the drag release state is a state in which the drag force does not act on the spool 3 at all, and the spool 3 is in a freely rotatable state. The drag lock state is a state in which the maximum drag force close to the lock state acts on the spool 3, and is mainly used for collecting a device or the like when the spool 3 is locked.

The brake disk 35 is, for example, a washer-shaped disk member made of stainless steel, and has a plurality of mounting screws 40 arranged on the radially inner side surface at intervals in the circumferential direction.
Thus, the spool 3 is non-rotatably mounted on the outer surface of the left flange portion 3 b of the spool 3. The mounting portion 35a of the mounting screw 40 of the brake disk 35 is annularly recessed from a radially outer portion. As a result, the drag area, particularly the drag area in the radially outward direction is less likely to be limited, and the brake disc 3 having the maximum diameter corresponding to the outer diameter of the spool 3 is formed.
5 becomes available.

The friction disc 36 is arranged to face the brake disc 35. A ring-shaped friction plate 36a made of a wear-resistant material such as carbon graphite or fiber reinforced resin is fixed to a surface of the friction disk 36 facing the brake disk 35 by an appropriate fixing means such as a screw. The friction disk 36 has a cylindrical boss portion 36b protruding outward in the axial direction at the center thereof.
A pin 2a that penetrates the spool shaft 2 along the radial direction of the spool shaft 2 and is attached to the spool shaft 2 is locked. Thus, the friction disk 36 is non-rotatably mounted on the spool shaft 2 and rotates together with the spool shaft 2. A ratchet wheel 50 of a reverse rotation preventing mechanism 9 is mounted on the left end face of the boss portion 36b of the friction disc 36 in FIG. Also, the friction disc 36
Is covered by a cover member 39. The boss portion 36b of the friction disc 36 extends through the cover member 39 toward the bearing 31a. A seal member 39a is interposed between the penetrating portion of the cover member 39 and the boss 36b.

[Structure of Drag Adjustment Mechanism] As shown in FIG. 1, the drag adjustment mechanism 8 includes a drag operation lever 41 which swings with respect to the spool shaft 2 and a lever drag mechanism 7 which swings the drag operation lever 41. And a conversion mechanism 42 that converts the movement in the direction of the spool axis.

The drag operation lever 41 is swingably mounted on the boss 11a of the reel unit 1 between a braking release position shown by a solid line in FIG. 2 and a maximum braking position (drag lock position) shown by a two-dot chain line. ing. The drag operation lever 41 can adjust the drag force of the lever drag mechanism 7 by swinging, and swings concentrically with the spool shaft 2. The drag operation lever 41 has a lever portion 41a that is swingably mounted on the boss portion 11a, and a knob portion 41b fixed to a tip of the lever portion 41a. The base end of the lever portion 41a is non-rotatably locked to the conversion mechanism 42.

The conversion mechanism 42 converts the swing of the drag operation lever 41 into the movement of the lever drag mechanism 7 in the spool axis direction, and swings in response to the swing of the drag operation lever 41 per unit swing angle. Lever drag mechanism 7 on the way
Is rapidly increased in the spool axial direction.
The conversion mechanism 42 includes, as shown in FIG. 3, a first cam portion 43 that is non-rotatably locked at a base end of the drag operation lever 41.
The second cam portion 44 is provided so as to be able to press the lever drag mechanism 7 in the first axial direction on the left side in FIG. 1 and engages with the first cam portion 43.
A return spring 45 (FIG. 1) for urging the lever drag mechanism 7 in the second axial direction opposite to the first axial direction in FIG. 1 and a drag force at a predetermined swing position of the drag operation lever 41 And a drag fine adjustment unit 47 capable of fine adjustment of the drag.

As shown in FIGS. 3 and 4, the first cam portion 43 is a stepped cylindrical member having a large outer diameter on the left side in FIG.
At one end of the small diameter (the right end in FIG. 3), a drag operation lever 4 is provided.
Parallel chamfers 4 for non-rotatably locking the base end
3a are formed. An oval hole 41a is formed at the base end of the drag operation lever 41 so as to be engaged with the chamfered portion 43a. As a result, the drag operation lever 41 is non-rotatably locked to the first cam portion 43 and is swingably supported by the reel body 1.

b and a flat surface 46 formed following the second inclined surface 46b
and two inclined cams 46 having a distance c in the circumferential direction.

As shown in FIG. 5, the first inclined surface 46a is
The inclination angle α with respect to a plane perpendicular to the spool shaft 2 is, for example, in the range of 1 to 15 degrees,
6b is a slope that is steeper than the first slope 46a, for example, the slope angle β is in the range of 30 degrees to 70 degrees. The first inclined surface 46a is used for normal drag adjustment, and the second inclined surface 46b is used for rapidly increasing the drag force to shift the spool 3 to a drag locked state close to a locked state. The flat surface 46c is a surface orthogonal to the spool shaft 2, and is used to maintain the spool 3 in a drag locked state close to a locked state. A concave portion 46d is formed in the flat surface 46c, and a click feeling at the drag lock position can be given by the concave portion 46d, so that the spool lock position can be recognized.

The second cam portion 44 is moved in the spool axial direction by the rotation of the first cam portion 43.

The pressing member 48 is a flanged cylindrical member having a large-diameter flange portion 48a and a small-diameter cylindrical portion 48b, and is provided on the outer peripheral surface of the flange portion 48a on the inner peripheral surface of the boss portion 11a in the spool axial direction. Movably and rotatably. Collar 4
A ring-shaped pressing portion 48c that can contact the outer ring of the bearing 31b is formed on the outer peripheral side of 8a. Also, the cylindrical portion 48
b, an external thread portion 48 screwed to the cam member 49
d is formed. An oval locking hole 48e is formed in the inner peripheral portion of the pressing member 48. The locking hole 48e has a section in which the tip of the adjustment pin 52a of the drag fine adjustment portion 47 is locked so as not to rotate. When the pressing member 48 is rotated by the drag fine adjustment portion 47, the position in the spool axis direction with respect to the non-rotating cam member 49 changes, and the drag force is slightly reduced even at the same swing position of the drag operation lever 41. Can be adjusted.

The cam member 49 has a large diameter portion 49a and a small diameter portion 4a.
9b. Cam member 49
A pair of cam pins 49c that engage with the inclined cam 46 are protruded outward in the radial direction at the boundary between the large-diameter portion 49a and the small-diameter portion 49b. Each cam pin 49c
Of the boss 11a is locked in a pair of locking grooves 11b formed on the inner peripheral surface of the boss 11a so as to face each other along the spool axial direction. The side surface of the cam pin 49c can contact the inclined cam 46. On the inner peripheral surface of the cam member 49, a female screw portion 49d screwed to the male screw portion 48d is provided.
Are formed. Thus, the cam member 49 is mounted on the boss 11a so as to be non-rotatable and movable in the axial direction. The cam member 49 comes into contact with the inclined cam 46 and moves in the spool axial direction by swinging of the drag operation lever 41.
During this swinging, the first inclined surface 46a is changed to the second inclined surface 46b.
, The amount of movement in the axial direction of the spool per unit swing accuracy sharply increases, the drag force can be rapidly increased, and the spool 3 can be braked in a drag locked state close to the locked state.

The return spring 45 is, as shown in FIG.
The friction disk 36 is mounted in a compressed state on the outer peripheral side of the spool shaft 2 between the friction disk 36 and the bearing 32a.
Urges the brake disc 35 (spool 3) in the direction away from the disc and urges the brake disc 35 (spool 3) rightward in FIG.

The drag fine adjustment section 47 has an adjustment knob 52 mounted on the reel body 1 so as to be rotatable and axially immovable coaxially with the spool axis. In the center of the adjustment knob 52, an adjustment pin 5 whose tip engages with the second cam portion 44
2a is provided integrally. At the tip of the adjustment pin 52a, there are formed parallel chamfers 52b which are non-rotatably locked in the locking holes 48e of the pressing member 48. In the drag fine adjustment unit 47 having such a configuration, the adjustment knob 5
2 is rotated, the pressing member 48 is rotated, and the pressing member 48 is rotated.
The position of the pressing member 48 in the spool axis direction with respect to the cam member 49 that is screwed with is changed. Thereby, the pressing member 48
Is changed, and the drag force can be finely adjusted even when the drag operation lever 41 is at the same swing position.

As shown in FIG. 1, the reverse rotation preventing mechanism 9 has a ratchet wheel 50 having a saw tooth (not shown) formed on an outer peripheral surface thereof, and is disposed on the outer peripheral side of the ratchet wheel 50, and a tip of the ratchet wheel 50 locks the saw tooth. This is a pawl-type one-way clutch having a pair of ratchet pawls 51.

The ratchet wheel 50 is mounted on the outer peripheral surface of the boss portion 36b of the friction disk 36 so as to be non-rotatable and movable axially outward (leftward in FIG. 1) by appropriate locking means such as serration. . As a result, the ratchet wheel 50 has the friction disc 3
6 so as to be non-rotatable and axially movable. The ratchet wheel 50 has a ring-shaped contact member 54 mounted concentrically on the left side surface in FIG. The contact member 54 is in contact with the right end face of the inner ring of the bearing 31a, and has a positioning portion 54a arranged on the outer peripheral surface in close proximity to the inner peripheral surface of the bearing housing 10a. When such a contact member 54 is provided, the ratchet wheel 50 can be mounted on the side plate 10 in a centered manner, so that the ratchet wheel 50 can be easily assembled. The bearing 3
The outer ring 1a is in contact with the side plate 10 as described above.

The ratchet wheel 50 is prevented from falling off from the side plate 10 by a pair of retaining members 55. The retaining member 55 is a metal plate member fixed to the side plate 10 and made of, for example, stainless steel.

As a result, the friction disk 36 cannot move outward in the spool axial direction (leftward in FIG. 4), that is, in a direction away from the brake disk 36, and the reverse rotation preventing mechanism 9
Thus, the rotation in the yarn winding direction is permitted and the rotation in the yarn feeding direction is prohibited.

Here, when the brake is released, there is a gap between the friction plate 36a of the friction disk 36 and the brake disk 35 as shown below the spool shaft center in FIG.
When in the braking state, as shown above the spool shaft core in FIG. By adjusting the degree of close contact, the drag force changes.

Next, the adjusting operation of the drag adjusting mechanism 8 will be described. In the lever drag mechanism 7, when the drag operation lever 41 is swung from the brake release position indicated by the solid line in FIG. 2 to the drag lock position indicated by the two-dot chain line, the lever operation lever 41 changes from a state shown below the spool axis in FIG. It changes to the state shown on the upper side. First, the first cam portion 43 of the conversion mechanism 42 rotates by the swing of the drag operation lever 41, and the second cam portion 44
The brake disk 3 of the lever drag mechanism 7 is moved in the axial direction.
5 moves leftward in the spool axis direction. Thus, the bearing 3
The outer ring 1b is pressed and moves, and the spool 3 is pressed via the pinion gear 17, the disc spring 34 and the bearing 32b to move leftward in the spool axial direction (leftward in FIG. 1).
The brake disc 35 also moves in the first axis direction. As a result,
The braking disc 35 approaches the friction disc 36. Then, when the brake disk 35 comes into contact with the friction disk 36 which cannot move in the axial direction and cannot rotate in the line payout direction, a drag force acts on the spool 3. Then, when the drag operation lever 41 is swung to the drag lock position,
The pressing force is maximized, and the brake disk 35 is pressed by the friction disk 36 to obtain a drag force close to the locked state. When the cam pin 49c contacts the second inclined surface 46b from the first inclined surface 46a during the swing of the drag operation lever 41, the moving force in the spool axis direction per unit swing accuracy sharply increases, and the drag force sharply increases. , Cam pin 49c
Comes into contact with the flat surface 46c to be in the drag lock state.

When the drag operation lever 41 is swung from a drag lock position shown by a two-dot chain line in FIG. 2 to a drag release position shown by a solid line, the drag lock lever 41 is moved downward from the drag lock state shown on the upper side of the spool shaft in FIG. The state changes to the drag release state.
First, the spool 3 is pressed by the urging force of the return spring 45 and moves to the right in FIG. As a result, a gap is formed between the braking disc 35 and the friction disc 36. Further, the spool 3 is pressed via the bearing 32a and moves rightward. Thereby, the braking of the spool 3 is released. On the other hand, when the spool 3 moves, the bearing 32b, the disc spring 3
4. The second cam portion 44 is pressed via the pinion gear 17 and the bearing 31b and retreats to the right in FIG. Then, when the drag operation lever 41 swings to the drag release position, it moves to a state below the spool axis in FIG.

On the other hand, when the fish is hooked on the device and the spool 3 rotates in the line pay-out direction, the rotation of the spool shaft 2 in the line pay-out direction is prohibited by the reverse rotation inhibiting mechanism 9. The rotation is prevented, and the drag force set on the spool 3 acts.

Next, a method of operating the lever drag reel will be described. When winding the fishing line on the spool, the handle 4 is rotated in the line winding direction. Then, the rotation of the handle 4 is transmitted to the spool 3 via the handle shaft 5, the main gear 16, the pinion gear 17, the spool shaft 2, and the lever drag mechanism 7, and the spool 3 rotates.

On the other hand, when it is desired to lock the spool 3 when the device is stuck, the drag operation lever 41 is swung from the drag release position shown by the solid line in FIG. 2 to the drag lock position shown by the two-dot chain line. . Then, the second cam portion 44 is pressed, the lever drag mechanism 7 enters the drag lock state, and the spool 3 comes to a state close to the lock state. After winding the fishing line and removing the dander in this state,
Pull the fishing rod straight toward the device. By doing so, the counterpart object, the hook, the fishing line, or the binding portion thereof that has been hung up are damaged, and the device or a part of the device can be collected.

[Other Embodiments] (a) In the above embodiment, a lever-drag dual-bearing reel in which a drag mechanism is provided around a spool shaft has been described as an example, but a drag mechanism is provided around a handle shaft. The present invention can be applied to a drag adjusting mechanism of another type of dual-bearing reel, such as a provided star drag type drag mechanism. Specifically, a spiral groove may be formed around the handle shaft, and the pitch of the groove may be increased in the middle. In addition, a rotatable pin that protrudes radially inward may be provided on the inner peripheral surface of the star drag instead of the female screw. By such engagement of the pin and the spiral groove, the amount of movement of the star drag per unit rotation can be rapidly increased during the rotation, and the spool 3 can be brought closer to the locked state.

(B) In the above embodiment, the lever drag mechanism is provided on the side opposite to the handle mounting side of the spool 3.
A lever drag mechanism may be provided on the handle mounting side. In this case, the drag force may be maximized when the spool shaft is pulled toward the handle (right side in FIG. 1). Further, the turning force of the handle may be directly transmitted from the drag mechanism to the spool without passing through the spool shaft.

(C) In the above embodiment, the inclined cam is provided only in the first cam portion. However, the inclined cam may be provided also in the second cam portion. Further, the configuration of the conversion mechanism is not limited to the cam mechanism, and other mechanisms such as a link and a screw may be used as long as the mechanism can convert rotation of the drag adjustment member into movement in the spool axial direction.

(D) In the above embodiment, the sliding of the brake disk or the friction disk is allowed, but the brake disk or the friction disk engages with the outer peripheral portion or the inner peripheral portion when the pressing force exceeds a predetermined set value. For example, an engaging portion made of an elastic body is provided,
The two disks may be completely locked in the drag lock state.

(E) As shown in FIG. 6, the second inclined surface 4
A plurality of (for example, two) protrusions 46e may be formed in the middle of 6a at intervals in the rotation direction of the drag operation lever 41. When such a convex portion 46e is formed, the convex portion 46e
As a result, a click feeling is obtained, and the operator can recognize the turning position of the drag operation lever 41 within the turning range. For this reason,
It is possible to prevent the user from accidentally operating in a state close to the drag lock state.

[0054]

According to the present invention, the amount of movement of the drag mechanism in the spool axial direction is rapidly increased during the rotation with respect to the amount of rotation of the drag adjustment member per unit, so that a spool lock mechanism is provided. The spool can be brought closer to the locked state by the drag mechanism. Therefore, a space for accommodating the spool lock mechanism is not required, and the weight increase due to the provision of the spool lock mechanism and the accommodation space does not occur, so that the spool can be brought closer to the locked state while reducing the size and weight. .
