[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fishing line take-up driving mechanism for winding a fishing line around a spool. The present invention relates to a fishing reel such as a bearing type reel or a spinning reel, and more particularly to a structure for preventing a screw member from loosening.

[0002]

2. Description of the Related Art Conventional fishing reels are disclosed in
As disclosed in Japanese Patent Application Laid-Open No. 5-108873 and Japanese Utility Model Application Laid-Open No. 57-171415, a rotating body [both shaft → handle shaft] is provided on the drive shaft [both shaft → handle shaft, spinning → pinion] of the fishing line winding drive mechanism. -Mum, spinning → rotor]
Of the nut, which is to be prevented from rotating, and fixed by tightening, the locking body which stops and locks the rotation of the nut outside the nut tightened with the predetermined tightening torque is screwed to the rotating body (handle arm, ro Screw).

[0003]

However, such a conventional technique requires a screw for fixing the locking body to the rotating body with a screw. Handling such a small screw and tightening the screw are required. Since a process is required, workability is poor, and there is a problem that screws are easily lost.

Therefore, according to the present invention, a screw member for fastening and fixing a rotary body of a reel to a drive shaft of a fishing line winding drive mechanism for winding a fishing line can be prevented from loosening with high workability and high reliability. An object of the present invention is to provide a fishing reel having a structure.

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention relates to a fishing line winding drive mechanism for winding a fishing line around a spool. in due connexion fastened fish reel fishing, thereby forming an engagement portion for detent engagement with the threaded member inside the locking projection of the cap having a resiliently deformable latching protrusion The gist of the invention is that it is detachably fixed to a locking portion formed on the rotating body by elastic deformation.
You . The rotating body is a handle arm of a fishing reel.
The gist is that In addition, the rotating body
Is a spinning reel rotor for fishing
Things .

[0006]

The engaging portion formed inside the cap is engaged with the screw member, and the elastically deformable locking projection is provided on the fishing reel.
Since it is detachably fixed by elastic deformation to a locking portion formed on a rotating body such as a handle arm of a wheel or a rotor of a spinning reel, there is no need for screws and the efficiency of assembly work is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 3 show a first embodiment according to the present invention of a dual-bearing type reel.

The handle arm 7 is a screw member 6 such as a nut.
The drive gear 8 is fastened and fixed to the drive shaft 5, and a drive gear 8 is mounted in the side plate 10 at the other end of the drive shaft 5 so as to be integrally rotatable. The drive gear 8 meshes with the pinion 9, and the rotation of the pinion 9 rotates the spool 11 to wind the fishing line.

A nut 6 for fastening and fixing a handle arm 7 as a rotating body which rotates together with the drive shaft 5 is usually gradually loosened by using a reel. In order to prevent this loosening, a synthetic resin molded cap 1 as shown in the enlarged view of the cap in FIG. 3 is prepared. As shown in the cross-sectional view taken along the line A--A in FIG. The locking portion 3 has two locking projections 4 that are elastically deformed and locked.

Next, the nut 6 and the cap 1 are actually assembled by first rotating the nut 6 with a predetermined fastening torque. Then, the engaging portion 2 is inserted into the outer peripheral convex portion of the nut 6.
And the locking assembling operation of the cap 1 in which the locking projections 4 on both sides are locked to the locking portions 3 of the handle arm 7 by elastic deformation, is completed with one touch. The cap 1 reliably prevents the nut 6 from being loosened due to various irregular loads.

As described above, according to the present invention, the engaging portion 2 of the integrally molded cap 1 is engaged with the nut 6 and the locking projection 4 is locked with the locking portion 3 of the handle 7. Since the assembling work of the cap 1 can be performed with one touch, the workability of assembling is improved as compared with the conventional example, small parts such as screws are eliminated, and the reliability is improved.

FIGS. 4 and 5 (BB sectional views) show a second embodiment according to the present invention. The difference from the first embodiment is that the locking projections 13 for locking the cap 12 are provided not at the middle but at both ends as in the cap 1, and the corresponding locking of the handle 7 is performed by utilizing elastic deformation. That is, both sides of the handle thickness are locked to the portion 14 so as to be clamped. The shape of the engaging portion 2 engaging with the nut 6 is the same as that of the first embodiment. In the cap 12 of this embodiment, the peripheral shape of the locking projection 13 is simplified, and the locking force of the cap 12 is strengthened and stabilized. Each of the above caps can also be used for a single bearing reel.

FIG. 6 shows a third embodiment according to the present invention.
This embodiment is different from the dual-bearing type reels shown in the first and second embodiments in that the present invention is applied to a locking nut for tightening a rotor of a spinning reel. Spinning tree of Fig. 6
In the case of the pinion, the handle 20 is rotated to rotate the drive gear 21 and transmitted to the pinion 22 to rotate the drive shaft 23 formed integrally with the pinion 22.

A rotor 24 that rotates together with the drive shaft 23 is fastened and fixed to the tip of the drive shaft 23 by a nut 6.
A spool shaft 2 is provided in the pinion 22 and the drive shaft 23.
5 is inserted, and the fishing line moves back and forth to
It is wound around 6. In this case, the drive shaft 23 and the rotor 24
The loosening of the nut 6 caused by the impact at the time of stopping the rotor from rotating, which is applied to the screw fixing portion, is provided with a cap 1 of the same type as that of the first embodiment as shown in FIG. 2 is engaged with the outer periphery of the nut 6 and the locking portion 3 of the rotor 24
As a result, the locking projection 4 is locked by elastic deformation, so that loosening of the nut 6 can be reliably prevented.

The cap 12 of the second embodiment can of course be used. Further, the cap 1 or the cap 12 can be assembled with one touch, and small parts such as screws are not required, so that the assembling workability is improved and the reliability is improved.

[0016]

As is apparent from the above description, according to the present invention, since a small part such as a screw is not used, the rotary body of the reel is driven by the fishing line winding drive mechanism for winding the fishing line. The screw member to be fastened and fixed to the shaft can be prevented from being loosened with good workability, the cost can be reduced by removing the screw member, and there is no unevenness in the screw mounting portion, so that there is an effect that dust hardly adheres to the surface.
