DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening member detent structure, and more particularly, to a fastening member which is screwed to a second member for fastening a first member of a fishing reel having at least a flat surface to a rod-shaped second member. The present invention relates to a fastening member detent structure of a fishing reel for detenting a member.

[0002]

2. Description of the Related Art In fishing reels such as spinning reels and dual-bearing reels, for example, a rod or pinion gear or a handle shaft (an example of a second member) is provided with a rotor or a handle (an example of a first member) and a nut (an example of a fastening member). (Example). Since this nut rotates together with the pinion gear and the handle shaft, it is easy to loosen due to inertial force and vibration acting on the rotor and the handle.

In order to prevent the nut from loosening,
A thin metal retainer is attached to the fixing nut. The retainer is a substantially raindrop-shaped member made of sheet metal having a large-diameter portion formed at one end and a small-diameter portion formed at the other end. In the large diameter portion, for example, when the nut is a hexagonal nut having six outer peripheral corners, a star-shaped nut locking hole having twelve inner peripheral corners such that two hexagons are displaced by 30 degrees. Are formed, and the outer peripheral shape of the nut is 30 in the nut locking hole.
It can be locked non-rotatably every degree. The small diameter portion has a screw insertion hole through which a small screw can be inserted.For example, by screwing a small screw into a screw fixing hole formed on the front side of the rotor, the retainer is fixed to the rotor so that it cannot rotate, and the nut is fixed. It is stopped.

[0004]

In the above-described conventional rotation preventing structure, the nut locking portion only locks the nut at, for example, every 30 degrees. The position of the insertion hole and the screw fixing hole does not match. If the positions of the two holes do not match, the small screw cannot be screwed into the screw fixing hole, and the rotation of the nut cannot be stopped. For this reason, when rotating the nut with a tool to fix the rotor, the operator must fasten the nut while paying attention to both the tightening torque and the rotation phase of the nut. However, even if care is taken, if the nut does not turn in a rotation phase of between 30 degrees, it is necessary to further turn or loosen the nut so that the screw insertion hole of the retainer matches the screw fixing hole. If this is done, the tightening torque of the nut will fluctuate. If the tightening torque of the nut is too tight, the inner diameter of the pinion gear becomes small, and the pinion gear and the spool shaft come into contact with each other, so that the rotation of the rotor becomes heavy. On the other hand, if the tightening torque is too low, the rotor will rattle. If the nut tightening torque fluctuates in this manner, there is a possibility that the fixed state of the rotor with respect to the pinion gear and the rotational state of the rotor will be adversely affected.

SUMMARY OF THE INVENTION It is an object of the present invention to suppress fluctuations in the tightening torque of a fastening member for fastening a first member to a second member, thereby making it difficult to loosen the fastening member.

It has a cylinder 41 and a drum section 42 provided on the reel body 2b.

The brake cylinder 40 is a metal cylinder having a thin cylindrical shape with a bottom, and a sliding contact portion 40a at the tip of the peripheral portion is disposed between the drum portion 42 and the pressure contact portion 30d of the brake lever 30.

The rotating cylinder 41 has a large diameter portion 41a and a small diameter portion 4a.
1b, a stepped metal cylindrical member having a large diameter portion 41a and an external tooth portion 41c meshing with the inner peripheral portion of the braking cylinder 40.
Are formed. The one-way clutch 32 and the brake cylinder 40 are non-rotatably locked to the external teeth 41c. A bearing 43 is arranged between the large diameter portion 41a and the pinion gear 12. A bearing 44 is disposed outside the small diameter portion between the small diameter portion and the reel body 2b.

The rotating cylinder 41 is connected to the rotor 3 by the one-way clutch 32.
Are rotated integrally with each other in the yarn feeding direction, and are connected to the rotor 3 so that the rotating force of the rotor 3 does not act upon winding.

And a toggle spring mechanism 53. The operating shaft 52 is urged forward by a pressing spring 54, and moves forward when the lever 51 swings to the holding position due to engagement with the reel body 2b, and retracts when swinging to the release position.

[Rotor Assembling Procedure] When the rotor 3 is incorporated into the pinion gear 12, the braking unit 20 is mounted on the reel body 2 in advance. With the braking portion 20 mounted on the reel body, the cylindrical portion 3 a of the rotor 3 is moved to the pinion gear 12.
To the front part 12a. Then, the rotor 3 is non-rotatably mounted on the pinion gear 12 by the chamfered portion 12c formed on the front portion 12a of the pinion gear 12. Subsequently, the nut 15 is screwed into the male screw portion 12b of the pinion gear 12, and the rotor 3 is fastened to the pinion gear 12.

When the nut 15 is completely tightened with a predetermined torque, the retainer is mounted on the nut 15. At this time, the mounting position is adjusted so that the screw insertion portion 16d of the retainer is arranged on the screw fixing portion 18. This screw fixing part 18
Since it is constituted by the arc groove 18a having a central angle of 60 degrees, no matter what rotational phase the nut 15 stops,
By adjusting the mounting position, the screw insertion portion 16d is always located at the screw fixing portion 18.

When the screw insertion portion 16d is positioned on the screw fixing portion 18, the screw member 17 is inserted through the screw insertion portion 16d,
Tighten the screw member 17 with a screwdriver. This screw member 17
Has a self-tapping function, so that when the screw member 17 is rotated while being pressed by a driver, the screw member 17 bites into the screw fixing portion 18 and is screwed into the screw fixing portion 18 while tapping. As a result, the retainer 16 is fixed, and the nut 15 is prevented from rotating.

Here, the screw member 17 is screwed into the screw fixing portion 18 formed by the arc groove 18a, so that the nut member 17 is in any rotational phase.
Can be screwed into the screw fixing portion 18, and the retainer 16
Can be securely fixed. For this reason, the nut 15 can be prevented from rotating regardless of the rotational phase of the nut 15, and a variation in the tightening torque of the nut 15 can be suppressed, so that the nut 15 can be hardly loosened.

[Reel Operation and Operation] At the time of casting, the fishing line is paid out from the outer periphery of the spool 4 by tilting the bail arm 9 to the line releasing position and swinging the fishing rod. At the time of winding the fishing line, when the handle 1 is rotated in the line winding direction, the bail arm 9 returns to the line winding position by a return mechanism (not shown). The turning force of the handle is transmitted to the pinion gear 12 via the handle shaft 10 and the face gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the front portion 12a of the pinion gear. At this time, since the rotor 3 rotates in the line winding direction, this rotational force is not transmitted to the rotating cylinder 41. When the pinion gear 12 rotates, the rotation is transmitted to the oscillating mechanism 7 by an intermediate gear (not shown), and the spool shaft 8 reciprocates in the front-rear direction.

When exchanging the fish with the rotor 3 in the reverse direction, the lever 51 is swung to the release position. As a result, the operation shaft 52 moves backward. And brake lever 3
0 is rocked by the coil spring 34 to the braking release position.
In this state, the user interacts with the fish by operating the brake lever 30. When the fishing line is pulled by the fish and the rotor 3 reverses in the line payout direction, the rotational force is transmitted to the rotating cylinder 41 via the one-way clutch 32 as described above,
Further, it is transmitted to the braking cylinder 40. As a result, the braking cylinder 40 rotates integrally with the rotor 3.

Then, the operation lever 30a of the brake lever 30 is gripped with the middle finger by the gripping operation of the fishing rod while the leg 2d is sandwiched between the middle finger and the ring finger of the hand holding the fishing rod. Swinging in the clockwise direction, the pressure contact portion 30d of the brake lever 30
2 is pressed radially outward, the braking cylinder 40 is tilted to the position shown by the two-dot chain line in FIG. 2, and the outer surface of the sliding contact portion 40a is pressed against the brake liner 42b. As a result, a braking force acts on the rotor 3 that rotates in the reverse direction. This braking force can be adjusted by adjusting the force applied to the brake lever 30,
The reverse rotation amount of the rotor 3 can be arbitrarily adjusted. During this adjustment,
Since the operation lever 30a can be finely operated with the middle finger, the braking force can be finely adjusted.

When the rotor rotates at the time of winding or unreeling, the nut 15 is easily loosened due to vibration or rotation. Also, if the tightening torque of the nut 15 fluctuates,
The rotation of the rotor is likely to be heavy or rattle. However, in the present embodiment, the nut 1 has a predetermined torque.
Regardless of the rotational phase of the nut 15 when the nut 5 is tightened, the nut 15 can be reliably prevented from rotating. For this reason, the tightening torque of the nut 15 can be made hard to fluctuate, the rotation of the rotor 3 becomes light, and
Rattle is less likely to occur.

When moving the fishing spot or storing the reels, the lever 51 is swung toward the holding position. As a result, the operation shaft 52 moves forward, and the brake lever 30 swings to the braking position. When the brake lever 30 is at the braking position, the braking cylinder 40 is braked in the same manner as during braking.
As a result, the fishing line is not paid out by the weight of the tackle or the like.

[Other Embodiments] (a) In the above embodiment, the screw fixing portion 18 is not
8a, but may be formed by an annular groove 18b as shown in FIG. The groove width of the annular groove 18b is the same as that of the embodiment. In this case, the screw insertion portion 16d is always located at the screw fixing portion 18 regardless of the position where the retainer 16 is mounted on the nut 15, so that the mounting of the retainer 16 is further facilitated. Further, the structure of the nut locking portion 16c may be simple.

Even in such a configuration, the screwing position of the screw member 17 can be changed according to the rotation phase of the nut 15, so that even if the nut 15 is tightened with a predetermined torque, the nut 15 can be reliably prevented from rotating.

(C) In the above embodiment, the rotation preventing structure is used for the nut 15 for fastening the rotor. However, the rotation preventing structure can be applied to the rotation preventing of other nuts such as the nut for fastening the handle of the dual bearing reel.

The crank arm 120 constituting 02 is non-rotatably mounted. A handle handle 121 is rotatably attached to the tip of the crank arm 120. At the tip of the handle shaft 115, a chamfered portion (both not shown) parallel to the male screw portion is formed.

As shown in FIG. 8, a hexagonal cap nut 125 for fixing the crank arm 120 to the handle shaft 115 is screwed into the male screw portion. Cap nut 12
5 is provided with a retainer 126 for preventing the cap nut 125 from rotating. The retainer 126 has the same structure as the above embodiment. The retainer 126 is fixed to the crank arm 120 by a tappable screw member 127. The screw member 127 is connected to the crank arm 1.
20 is screwed into a screw fixing portion 128 formed in an arc shape. The center angle R of the arc of the screw fixing portion 128 is, for example, 60 degrees. With such a configuration, effects similar to those of the above-described embodiment can be obtained.

As described above, the present invention can be applied to all fishing reels in which the first member having a flat surface with a nut is mounted on the second member in a rod shape.

(D) In the above-described embodiment, the hexagonal nut is prevented from rotating. However, the shape of the nut to which the rotation preventing structure of the present invention is applied is not limited to this. The present invention can be applied to a structure in which nuts of all shapes such as nuts and nuts having parallel chamfers are prevented from rotating.

(E) In the above-described embodiment, a nut is exemplified as the fastening member. However, the fastening member is not limited to the nut, and other screws such as a hexagon bolt may be used.

[0065]

According to the present invention, since the screw fixing portion is formed along the direction intersecting the radial direction of the fastening member,
Even if the rotation phase of the fastening member is shifted, the head of the screw member can be brought into contact with the outer peripheral shape of the fastening member. For this reason, a variation in the tightening torque of the fastening member for fastening the first member to the second member can be suppressed, and the fastening member can be hardly loosened.

Further, according to another aspect of the present invention, since the screw fixing portion is formed along a direction intersecting the radial direction of the fastening member, even if the rotation phase of the fastening member is deviated, the fastening member is not fixed. The screw member inserted through the screw insertion portion of the retainer attached to the screw can be screwed into the screw fixing portion. For this reason,
Variations in the tightening torque of the fastening member for fastening the first member to the second member can be suppressed, and the fastening member can be hardly loosened.
