[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fishing line take-up transmission mechanism for preventing a fishing line winding transmission mechanism from reversing in a fishing line payout direction by a reverse rotation preventing mechanism. A state in which the claw body is separated from the tooth portion in conjunction with the rotation of the fishing line winding transmission mechanism in the fishing line winding direction while being configured with a tooth portion formed on a drive shaft constituting the line winding transmission mechanism. The present invention relates to a spinning reel reverse rotation prevention mechanism including a posture switching mechanism that allows a state in which the claw body meshes with the tooth portion in conjunction with rotation of the fishing line winding transmission mechanism in the fishing line payout direction.

2. Description of the Related Art Conventionally, as a mechanism for preventing reverse rotation of a spinning reel constructed as described above, there is one disclosed in Japanese Utility Model Publication No. 63-64. In this conventional example, a drive shaft for winding a fishing line is used. In contrast, a cam-shaped control body is provided via a friction structure, and when the drive shaft rotates in the direction in which the fishing line is wound, the pawl body is changed by the power from the drive shaft to change the pawl body into a ratchet wheel. To prevent the contact sound between the pawl and the ratchet wheel,
It is configured to suppress each wear and tear.

[0003]

Considering the above-mentioned prior art, the claw body is separated from the ratchet wheel during the winding drive of the fishing line, so that the generation of contact noise is prevented. Excellent quietness,
On the other hand, it has a good surface that the wear of the claw body etc. is reduced, but for example, as in the case of interacting with a strongly pulling fish, it winds up for a short time after the action of bringing the fish using the elastic force of the rod Assuming that the operation of performing the operation is repeated, at the time of the hoisting operation, the claw body is in a posture separated from the ratchet wheel, and immediately after this hoisting, when operating the rod and pulling the fish by the elastic force of the rod, Changes the posture of the control body due to the reversal of the drive shaft due to the tension of the fishing line, the pawl body changes to the posture in contact with the ratchet wheel, but since this posture change is not so quick, the drive shaft The fishing line may be unnecessarily fed before the reversal is prevented, and there is room for improvement in efficiency in actual fishing. SUMMARY OF THE INVENTION An object of the present invention is to rationally configure a reverse rotation preventing mechanism for quickly preventing a reverse rotation operation of a drive system without impairing the above-described quietness and reduction in wear.

[0004]

SUMMARY OF THE INVENTION The present invention is characterized in that the fishing line take-up transmission mechanism is reversed in the fishing line payout direction.
The reverse rotation preventing mechanism is constituted by a claw body supported by the reel body and a tooth portion that rotates in conjunction with the fishing line winding transmission mechanism, and the rotation of the fishing line winding transmission mechanism in the fishing line winding direction. The claw body is switched to a state in which the claw body is separated from the teeth, and the claw body engages with the teeth in conjunction with the rotation of the fishing line winding transmission mechanism in the fishing line payout direction. with an attitude switching mechanism that, the attitude switching mechanism, said fishing line winding
And accelerating gear transmission unit for the driving shaft constituting the come-up transmission mechanism receives power transmission, the speed increasing is moving is <br/> drive the gear transmission unit constituted by an operation section for posture changing the pawl body The operation and effect are as follows.

[0005]

When the fishing line take-up transmission mechanism is driven in the direction in which the line is taken up, power is transmitted from the drive shaft which rotates in the direction in which the line is taken up, and the gear transmission is driven in an increased speed state. The speeded gear transmission acts on the claw body to change the posture of the claw body so as to be separated from the teeth. When the fishing line take-up transmission mechanism is operated in the reverse direction in the fishing line take-out direction, the power transmission is driven by the drive shaft rotating in the fishing line take-up direction, and the gear transmission is driven in the reverse direction in a speed-up state, and the claw body is moved. The posture is changed to a state in which it engages with the teeth. That is, since the speed of the mechanism for prompting the posture change of the claw body is increased, the reverse rotation preventing mechanism can be switched to the reverse rotation preventing state in a short time.

[0006]

[Effects of the Invention] Therefore, the fishing line winding transmission can be performed without impairing the quietness and the reduction in abrasion when winding the fishing line.
The reverse rotation of the rotation mechanism to quickly blocked, reverse rotation prevention mechanism you suppress wasteful feeding of the fishing line is was reasonably configuration. Drive at increased speed based on the drive shaft that drives the teeth
Rotation speed of the teeth
If the claw body can be operated at a high speed , the claw body can quickly engage and disengage from the teeth, not only preventing reverse rotation but also separating more quickly than the teeth when winding the yarn, and It is also possible to avoid the generation of a contact noise due to the contact with the claw body, which can contribute to ensuring quietness.
