[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel provided with a one-way clutch for preventing a rotor provided at a front portion of a reel body from rotating in a fishing line payout direction.

[0002]

2. Description of the Related Art Conventionally, a spinning reel constructed as described above is disclosed in Japanese Utility Model Publication No. 63-64. In this conventional example, a ratchet is mounted on a transmission shaft for transmitting power from a handle to a rotor. A one-way clutch is formed by externally fixing the wheel and providing a swinging pawl body which engages with and disengages from the ratchet wheel at the front of the reel body.

[0003]

In the conventional construction, the number of teeth of the ratchet wheel is set to eight, and when the rotor rotates in the fishing line payout direction, the pawl body is engaged from the outer peripheral direction of the wheel. In addition, the rotation of the rotor is regulated. Also, in normal fishing, when a fish is caught, the rod is shaken to perform the awase, but in the case of this awase, after the rotation of the rotor is blocked by the one-way clutch described above, The fishing line tension makes it possible to fish.

However, in a conventional one-way clutch,
Since the number of teeth of the ratchet wheel is set to about 8, the asobi in the direction in which the rotor draws out the fishing line is relatively large. There is still room for improvement, as it is not possible to make sure the delay due to the delay. Therefore, it is conceivable to increase the number of teeth of the ratchet wheel. However, if the number is simply increased, the size of the part where the teeth contact the claw body (the part having a posture along the radial direction of the teeth) is considered. Size), and there is room for improvement in strength. SUMMARY OF THE INVENTION An object of the present invention is to rationally configure a spinning reel capable of quickly performing an awase operation without reducing the strength of a reel body by forming teeth of a ratchet wheel.

[0005]

According to the present invention, there is provided a one-way clutch comprising a one-way clutch for preventing a rotor provided at a front portion of a reel body from rotating in a fishing-line feeding direction. A plurality of teeth formed on the inner peripheral surface of the rotor, and a rocking operation for engaging the teeth and restricting the rotation of the rotor, releasing the engagement with the teeth, and retracting to the separated position. constituted by a pawl body movement, the abutment sides of the pawl member of the teeth, the its abutment side and the opposite side, front
The inclined line along the contact side and the side along the opposite side
It is formed by setting to the inclined state where the inclined line intersects,
Between the intersection of the two inclined lines and the rotation of the rotor
Assuming a radius line connecting the heart, the radius line and the contact side
Angle between the radius line and the opposite side
The contact angle should be smaller than the included angle formed by the inclined line of the surface.
The degree of inclination between the side surface and the opposite side surface is set, and the number of the tooth portions is 18 to when the diameter of the rotor is 50 mm to 70 mm.
28, the claw body is urged in a direction to engage with the tooth portion, and the rotation of the rotor in the fishing line winding direction is frictionally interlocked with the rotation of the rotor to engage with the claw body. The claw body is separated from the tooth portion against the force, and when the rotor is rotated in the fishing line dispensing direction, the claw body is separated from the claw body and engaged with the tooth portion by frictionally interlocking with the rotation of the rotor. (Claim 2) In the invention according to claim 1, the rotor is made of resin, and the operation and effect are as follows.

[0006]

(Claim 1) As shown in FIGS. 1 and 2, when the whirlwind operation is performed, the rotor 4 attempts to reverse once in the fishing line payout direction. When the claw body 14 moves away from the claw body 14 for the first time, the biased claw body 14 operates in the engaging direction to engage with the tooth portion 4A. Then, the rotor 4 stops the reverse rotation. In this case, the pawl body 14 is engaged with the tooth portion 4A of the one-way clutch C. The number of the tooth portions 4A is more than twice the number of the tooth portions 4A of the conventional one-way clutch C. As a result, asobi in the extending direction of the rotor 4 is greatly reduced, and since the teeth 4A are formed on the inner peripheral surface of the rotor 4, the number of teeth 4A is increased as described above. This tooth part 4A and the nail body 14
There is no reduction in the size of the contact area with the contact. 18-2
The value of 8 is a value obtained based on the diameter of a conventional spinning reel rotor 4 (about 50 to 70 mm). By setting the value in this range, it is possible to obtain a good asobi without reducing the strength. Has been confirmed by experiments. When the rotor 4 is rotated in the direction of winding the fishing line, the cam body 15 frictionally interlocks with the rotation and lifts the claw body 14 away from the tooth portion 4A against the urging force.

In addition, the cam body 15, which operates in friction with the rotation of the rotor 4, contacts the claw body 14 to separate the claw body 14 from the tooth portion 4 A, and separates from the claw body 14 to cause the claw body to move. Since the configuration in which the teeth 14 can be engaged with the teeth 4A is adopted, it is also necessary to determine the number of the teeth 4A in consideration of the operation speed of the cam body 15. In other words, the greater the number of teeth 4A, the finer the stop phase can be. However, since the pawl 14 receives the urging force and swings in the direction of engagement with the teeth 4A, the stop phase is fine. In order to cope with this, it is necessary to increase the urging force on the claw body 14 to improve the operation speed of the claw body itself. However, the nail body 14 has the tooth portion 4A.
In the case where the cam body 15 is further separated, the cam body 15 is opposed to the urging force.
When the urging force acting on the claw body 14 is increased as described above, the cam body 1
The push-up force at 5 must also be increased, but since the cam body operates in friction with the rotation of the rotor 4, there is a limit in increasing the push-up force. Then, the urging force cannot be made too large due to the balance between the operation of the claw body 14 and the cam body 15, and the calming is performed with an appropriate urging force. Therefore, since the operation speed of the claw body 14 is affected, even if the number of the tooth portions 4A is increased, the claw body 14 may be engaged with the tooth portion 4A by skipping one tooth. It has been found through various tests that the above-mentioned reel having a rotor diameter of about 50 to 70 mm has the optimum number of teeth in the 18th to 28th positions.

The cross-sectional shape of the tooth portion 4A is such that since the side surface in contact with the claw body 14 is an inclined surface, the shear force acting on the base end portion of the tooth portion 4A can be reduced, and the side surface located on the opposite side of the side surface Are both inclined and along the contact side.
Slope line intersects with slope line along opposite side
Even if the claw body 14 comes into contact with the tip of the tooth part 4A when the claw body 14 engages with the tooth part 4A, the claw body 14 is formed along the contact surface of the tooth part 4A. As a result, the claw body 14 does not come into contact with the distal end portion of the tooth portion 4A and is prevented from entering the engagement side, and a reliable stopping action can be expected.
When the claw body 14 is preventing the rotor 4 from rotating in the reverse direction, a force for the rotor 4 to move in the reverse direction acts on the claw body 14, but the reverse rotation force of the rotor 4 extends along the circumferential direction. appear. However, the reverse rotation force of the rotor 4 is not
Because they act perpendicularly on the Setto side surface in Setto side surface of the A, this the abutment sides are inclined with respect to a radial line above
Thus, the reversing force also generates a component force in the radial direction according to the degree of inclination. Then, the component is claw body 1
4 oscillates in the radial direction and is a component force for separating from the contact side surface. However, in the case of the present invention, the inclination of the contact side is smaller than the inclination of the opposite side, so that the component force is small and the claw body 14 can be prevented from separating from the contact side. . Therefore, it is not necessary to increase the urging force for maintaining the pawl body 14 in the engagement posture in consideration of the component force in the reverse rotation preventing state, and it is not necessary to increase the frictional force for interlocking the cam body 15 with the rotation of the rotor 4. Absent. Then, at the time of winding the thread, the side surface opposite to the contact side surface is inclined, so that the claw body 14 is pushed up to the separated posture, and the pushing up action of the cam body 15 is assisted. Therefore, it is not necessary to increase the frictional force that causes the cam body 15 to rotate in association with the rotation of the rotor 4, and the rotation operation during the winding of the line can be performed lightly.

(Claim 2) The rotor 4 forming the tooth portion 4A
Is formed of resin, the tooth portion 4A requires a certain tooth width and tooth thickness from the strength surface. Therefore, in a reel having a rotor diameter of about 50 to 70 mm, the tooth portion 4A is formed on the inner peripheral surface of the rotor 4. The number of possible teeth is limited to a certain range (18 to 28).

[0010]

Accordingly, even in the case of using a cam body that controls the movement of the claw body in frictional connection with the rotor, the number of teeth and the side surface of the tooth part that contacts the claw body are inclined. By setting the cross-sectional shape to be formed, without decreasing the strength,
Thus, a spinning reel that can quickly perform an operation and that does not cause rattling even when used for a long period of time has been rationally configured.
