Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel capable of maintaining good performance even in a use environment in which seawater, water, foreign matter, etc. are likely to enter and adhere.

[0002]

2. Description of the Related Art In recent years, in order to reduce the weight and increase the strength of fishing reels, magnesium alloy is being used for the reel body and the constituent members. Further, usually, a fishing reel is equipped with a reverse rotation / reverse rotation prevention device for preventing rotation (reverse rotation) of the rotor and the spool in the fishing line feeding direction. Conventionally, this reverse rotation prevention device has been engaged with ratchet teeth and pawls, but recently, a rolling type one-way clutch is used so that a reliable matching operation can be performed.

Such a rolling type one-way clutch has an outer ring fitted to a support portion (supporting cylinder) of the reel unit, an inner ring fitted to the rotary shaft, and a rolling member arranged between the outer ring and the inner ring. The member is provided with a member such as a member and a retainer for holding the rolling member, but in particular, the outer ring portion is required to have sufficient hardness because a wedge action is performed. For this reason, the outer ring portion is usually manufactured by quenching a steel material and then forming a corrosion-resistant coating such as nickel plating, and this is fitted into a support cylinder of the reel unit to prevent rotation.

[0004]

By the way, the fishing reel is in an environment in which seawater or the like is likely to enter the inside of the reel body during actual fishing. Electrolytic corrosion (contact corrosion of dissimilar metals in the electrolyte) is likely to occur at the contact portion. As described above, in the rolling one-way clutch, since the outer ring and the reel unit are in contact with each other by dissimilar metals, when the electrolytic corrosion occurs, the support of the reel unit to which the outer ring portion is fitted is supported. The cylinder may corrode and play may occur in the direction of rotation.
There is a possibility of damage due to impact load when stopping reverse rotation.

Further, during actual fishing, a shock load in the direction of rotation when reversing is stopped is repeatedly applied to the support tube of the reel unit, so that the support tube of the reel unit is subjected to a surface treatment (anticorrosion treatment) for preventing electrolytic corrosion. Even if the above is applied, the rotation preventing portion of the inner circumference of the support cylinder with respect to the outer ring is likely to be damaged, and electrolytic corrosion may be accelerated from this portion.

The present invention has been made on the basis of the above-mentioned problems. In a fishing reel in which a reverse rotation preventing device constituted by a rolling type one-way clutch is incorporated in the support portion of the reel unit, the usage environment of the fishing reel is reduced. An object of the present invention is to provide a fishing reel capable of maintaining good performance for a long period of time at a severe fishing ground.

[0007]

In order to solve the above-described problems, the present invention provides a rolling type one-way clutch between a drive shaft that rotates in conjunction with a handle and a reel unit to reverse the drive shaft. In a fishing reel that constitutes a prevention device, the outer ring is fixed by interposing a protective member that covers the outer ring between the outer ring of the rolling one-way clutch and a support portion formed on the reel body. Is characterized by.

As described above, the protective member for covering the outer ring is interposed between the outer ring of the rolling type one-way clutch which constitutes the reverse rotation preventing device and the support portion formed on the reel unit, so that the actual fishing can be performed. Even if a shock load is repeatedly applied to prevent reverse rotation, damage to the fitting part in the outer ring support part of the reel unit is prevented, corrosion and rattling are suppressed, and good performance is always exhibited. Like In particular,
If the reel body is made of magnesium alloy,
The occurrence of electrolytic corrosion that tends to occur between the outer ring of the rolling type one-way clutch and the outer ring is effectively suppressed.

The slider 20 is attached to the rear end of the worm shaft 20 and holds the engagement pin 18. The worm shaft 23 extends parallel to the spool shaft 15 and has a gear 22 that meshes with the pinion 12a. The engagement pin 18 is engaged with a spiral groove formed on the outer circumference of the worm shaft. As a result, the worm shaft 23 fitted with the gear 22
However, when the handle 8 is rotated via the drive gear 10 as the handle 8 is rotated, the slider 20 (spool 5) is moved back and forth via the engagement pin 18.

With the above driving mechanism, the handle 8
When the rotor 3 is wound, the rotor 3 is rotationally driven via the drive gear 10 and the rotary cylinder shaft 12, and the spool 5 is moved back and forth via the oscillating mechanism as described above. It is evenly wound around the spool via the fishing line guide portion 3d provided on the bail support arm 3c of No. 3.

In this embodiment, the reel body 2, the rotor 3 and the spool 5 described above are made of a lightweight and high-strength magnesium-based metal (for example, a magnesium alloy containing Al, Zn, Mn, etc.). Has been done. In this case, it is preferable that the surface thereof is further subjected to anticorrosion treatment such as chromium oxidation treatment, dichromate treatment, stannate treatment or the like, coating, anodization treatment and the like.

A reverse rotation preventing device constituted by a rolling type one-way clutch 25 is incorporated in the reel body 2 so as to prevent the rotor 3 from rotating in the reverse direction. The rolling type one-way clutch 25 is a reel type one-way clutch. It is arranged between the cylindrical portion 2 b protrudingly formed on the front portion of the main body 2 and the rotary cylindrical shaft 12.

Next, the structure of the one-way clutch 25 will be described with reference to FIGS. One way clutch 25

That is, the retainer 28 is rotated by the rotation operation (switching operation) of the operation lever 32 to position each roller 29 in the free rotation area (reverse rotation possible state) or the wedge area (reverse rotation prevention state). The operating lever 3
It is configured such that the rotary cylinder shaft 12 can be switched between the forward / reverse rotation possible state / reverse rotation prevention state by switching operation of 2.

In the above-mentioned structure, the outer ring 27 of the one-way clutch is made of SUS or nickel-plated, and when an electrolyte substance such as seawater enters, the magnesium alloy (dissimilar metal) described above is introduced. Electrolytic corrosion is likely to occur between the reel body 2 formed in 1. In particular,
The outer ring portion is fixed to the reel body 2 and gives a shock load to the reel body 2 by the wedge action at the time of preventing reverse rotation, so that the surface treatment on the body side is damaged and peeled off, or The magnesium alloy itself is damaged, and electrolytic corrosion is accelerated.

In order to eliminate the above-mentioned problems, a protective member 35 is arranged between the outer ring 27 and the barrel portion 2b of the reel unit. In this case, the protective member 35 may be formed in a shape such that the cylindrical portion 2b of the reel unit and the outer ring 27 are completely out of contact with each other. For example, the outer ring 27 is shown in FIG. As described above, it is only necessary to form a cap shape (substantially cylindrical shape). In addition, when the reel body is formed of a magnesium-based metal as described above, the protection member 35 is formed of a material having a small potential difference from magnesium, such as an aluminum material or an aluminum-based alloy, to prevent occurrence of electrolytic corrosion. Although it can be prevented, it is possible to reliably prevent the occurrence of electrolytic corrosion by forming it with an insulator such as resin.

Further, since the outer ring 27 is provided with the roller accommodating portions 27b which are bulged at predetermined intervals, the cylindrical portion 2b of the reel unit and the protective member 35 are fitted and fixed thereto. However, in the present embodiment, the outer ring 27 is provided on the front end side.
The rotation preventing plate 38 is provided, and the inner periphery of the tubular portion 2b of the reel unit and the side wall of the protection member 35 interposed between the outer ring 27 and the tubular portion are formed in a circular shape.

The portion 38a is fitted and fixed in the recess 2c formed in the reel body. And
The outer ring 27 is formed with a cutout portion 27c into which the rotation stopping portion 38a is fitted, and the protective member 35 is also formed with a corresponding cutout portion 35a as shown in FIG. The notch 35b is formed so that the operating member 30 can rotate.

According to this structure, it is not necessary to form a recess corresponding to the bulged outer peripheral shape of the outer ring 27 in the cylindrical portion 2b of the reel unit 2 or the protective member 35, and therefore, it is formed at the time of alignment. It is not necessary to consider errors and the like, the die manufacturing is facilitated, and the man-hour and cost can be reduced. In addition, even when a shock load is repeatedly applied during reverse rotation prevention during actual fishing, the tubular portion 2 of the reel unit is protected by the above-mentioned protective member 35 and rotation preventing plate 38.
It is possible to prevent the occurrence of scratches on the inner circumference of b, suppress the occurrence of corrosion and rattling, and always maintain a good reverse rotation prevention function. Further, in this manner, the outer ring portion of the rolling type one-way clutch is free from rattling due to scratches, corrosion, etc. Therefore, the wedge action control of the roller 29 by rotating the retainer 28 is surely performed as described above. Will be able to do.
