A method of engaging the portion is known.

[0003]

[Problems to be solved by the device]

 However, in the former case, when the processing means for the outer ring and the fitting portion of the reel body is troublesome, and the gap formed between the two tends to cause backlash in the direction of rotation of the outer ring, there is little reverse play, which is a characteristic of the bending angle. The rolling type one-way clutch cannot fully exhibit the reverse rotation prevention function, and its performance degradation has the drawback that the hooking operation for fish cannot be performed reliably.

In the latter case, the impact load when the handle shaft rotates in the reverse direction concentrates on the end surface of the rotation-stopping engagement part, and the strength of the engagement part decreases, causing deformation or wear, which results in long-term use. During this time, the play in the rotation direction becomes large, and the degree of play when the handle shaft rotates in the reverse direction becomes large as described above, making it impossible to perform a reliable hooking operation and preventing the detent that is fitted in the opening of the outer plate. There is a problem that the joint part deteriorates the anti-rotation function due to impact with other objects or drop impact. The present invention solves these problems by supporting the rolling type one-way clutch on the reel body while maintaining sufficient strength, and does not deteriorate the characteristics of the rolling type one-way clutch with little reverse play. It is an object of the present invention to provide a reverse rotation preventing device for a fishing reel.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention uses a rolling one-way clutch between a handle shaft for rotating a spool and a reel body to prevent the handle shaft from rotating in the reverse direction. In the reel for reel, a locking member is provided between the outer peripheral surface of the outer ring of the rolling type one-way clutch and the inner peripheral surface of the reel body with which the outer ring is fitted, for locking each in the radial direction. It is a thing.

The locking portion is formed in a radial rod shape, is formed in a wedge shape in the axial direction, and is further annularly fitted in an opening portion of a reel body into which a rolling type one-way clutch is fitted. It can be provided between the coupling member and the outer ring.

[0007]

[Action]

 In the present invention, the outer periphery of the rolling type one-way clutch and the reel body to which the outer ring is fitted are locked by a locking member that locks each in the radial direction. On the other hand, the one-way clutch is retained in the opening of the reel body with sufficient strength and without rattling to prevent the handle shaft from rotating in the reverse direction, and the reverse rotation degree is reduced to reliably perform the hooking operation on the fish. be able to.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A spool shaft 5 to which a spool 4 is fixed is supported between reel side plates 2 and 3 of a reel body 1 of a dual bearing type reel, and the spool shaft 5 is a handle shaft 6 A rolling type one-way clutch which is configured to rotate in conjunction with a known driving gear, a pinion or other interlocking mechanism 7 and which is supported on the handle shaft 6 by a fitting portion 2'of the reel side plate 2. 8 is provided so that the handle shaft 6 does not rotate in the reverse direction with respect to the fishing line winding direction. Thus, between the outer peripheral surface of the outer ring 9 of the one-way clutch 8 and the inner peripheral surface of the fitting portion 2'of the reel side plate 2, there is provided a rod-shaped locking member 10 for locking each in the radial direction. The outer ring 9 is locked to prevent it from rotating. In the drawing, 11 is a rolling member of the rolling type one-way clutch 8, 12 is a holding member thereof, and 13 is an inner ring fitted to the handle shaft 6 to prevent rotation.

Since the embodiment of the present invention is constructed as described above, the impact load acting on the outer ring 9 of the rolling member 11 when the spool 4 is reversed by the feeding of the fishing line is caused by the fitting of the reel side plate 2 The handle shaft 6 is reversely rotated by a locking member 10 which is non-rotatably supported on the portion 2'and which has the characteristic of a rolling type one-way clutch and which has a small reverse rotation degree of play. Alternatively, the outer peripheral surface of the outer ring 9 may be formed in a circular cross-section, and the inner surface of the reel side plate 2 may be fitted in a fitting portion 2'having a circular cross-section.

In the embodiment shown in FIGS. 3 and 4, the cross section of the outer peripheral surface of the outer ring 9 and the inner peripheral surface of the fitting portion 2 ′ of the reel side plate 2 with which the outer ring 9 is fitted are each formed into a circular shape and the locking member is provided. The outer ring 9 and the reel side plate 2 of the reel unit 1 are radially engaged with each other by forming a wedge shape 10 in the axial direction over substantially the entire length of the outer ring 9. The manufacturing process in the supporting portion can be simplified to reduce the cost, the concentricity of the clutch 8 with respect to the handle shaft 6 can be improved, and the reverse rotation preventing performance can be further improved.

Further, in the embodiment shown in FIGS. 5 and 6, the annular fitting member 14 having inner and outer edges 14 ′ and 14 ″ at the open end of the fitting portion 2 ′ of the one-way clutch 8 of the reel side plate 2 is reeled. A radial locking for fixing the opening end edge of the main body 1 so as to be sandwiched between the inner and outer edges 14 ', 14 "and fixing it with the pin 15 and for locking the outer ring 9 on the inner edge 14' of the outer ring. A portion 10 ′ is provided, and a radial locking portion 10 ″ that locks and locks the reel side plate 2 is provided at the outer edge 14 ″, and serves as an opening fitting member of the reel body 1 for removing seawater and dust from the outside. The outer ring 9 of the one-way clutch is securely retained and retained with sufficient strength while preventing the intrusion into the directional clutch.

EFFECTS OF THE INVENTION The present invention is a locking system for radially locking the outer circumference of the outer ring of the rolling type one-way clutch supported by the fitting part of the reel body and the inner circumference of the fitting part of the reel body. By providing a member to prevent rotation, the rolling type one-way clutch can be reliably supported on the fitting part of the reel body without rattling against the impact load at the time of reverse rotation, and sufficient strength can be maintained. It is possible to prevent deterioration of the function of the reverse rotation preventing device having a small degree of reverse rotation play which is a characteristic of the clutch.

By forming the fitting portion of the reel body and the outer peripheral surface of the outer ring into a circular shape, the cost can be reduced by simplifying the assembling configuration and the concentricity of the one-way clutch with respect to the handle shaft can be improved. It is possible to improve the anti-reverse rotation performance.

Furthermore, when the locking member is provided between the annular fitting member fitted to the fitting portion of the reel unit and the outer peripheral surface of the outer ring, the outer ring is prevented while preventing seawater and other intrusion into the one-way clutch. It is possible to firmly and reliably support the reel unit without any play.
