Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a support mechanism between a metal movable displacement member and its support member in a fishing reel.

[0002]

2. Description of the Related Art Fishing reels mainly include a dual bearing reel and a spinning reel. In the former, rotating members such as a handle shaft and a spool shaft are rotationally displaced with respect to a supporting member such as a bearing. There are many support mechanisms, and in the latter, a spool shaft provided with a spool in addition to the rotation displacement mechanism has a rotating body and slides in an axial direction on a rotating shaft cylinder driven by a handle shaft via an oscillating mechanism or the like. There is also a displacing support mechanism.

[0003] In general, the components constituting the above-mentioned rotational displacement portion and sliding displacement portion of the support mechanism are made of different metallic materials in terms of durability and strength. However, since the frictional resistance during rotation or sliding displacement is large and catching occurs, and fishing reels are often used in harsh environments where seawater is likely to enter and adhere,
In particular, there is a defect that the electrolytic corrosion phenomenon occurs due to a potential difference generated between the two depending on the metal material used, which hinders a smooth rotating action and a sliding action and cannot withstand long-term use.

[0004] In order to remedy this drawback, a surface treatment is applied to the used metal material. However, it is difficult to prevent corrosion for a long period of time. It is a common practice to reduce the rotational resistance and sliding resistance by interposing a resin collar for use to prevent peeling of the surface to prevent corrosion.

[0005]

However, since the conventional resin collar is not fixed to a movable displacement portion such as a rotating portion or a sliding portion, handling operations during assembly and disassembly are troublesome and particularly small parts. It is easy to lose, and there is a problem in that if the position shifts during rotation or sliding, it causes poor rotation and poor sliding.

The present invention solves these problems, facilitates operation during manufacturing and assembly, and prevents loss of each member at the time of disassembly. It is an object of the present invention to provide a fishing reel capable of performing the following.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a fishing reel in which a fishing line can be wound around a spool by operating a handle. A resin collar for preventing electrolytic corrosion is interposed between the support members, and the resin collar is fixed to one of the support collars to form a unit. The metal movable displacement member and the metal support The supporting mechanism constituted by the members includes a handle shaft, a spool shaft, and the like in a dual-bearing fishing reel, and a rotational displacement action between bearings that respectively support these on a reel body, and a spinning reel for fishing. The rotational displacement action between the rotating barrel having the rotating body and the bearing supported by the spool body and the sliding rotating displacement action between the rotating barrel provided with the rotor and the spool shaft having the spool, etc. That. Further, as the fixing means for unitizing the resin collar, it is preferable that the elasticity is used to make the resin collar detachable by locking fitting or press fitting fitting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described with reference to the drawings of the embodiment. The embodiment shown in FIG. 1 is a case of a dual-bearing fishing reel, and side plates 1 and 1 'are fitted respectively. Bearings 4 and 3 are provided between the frames 3 and 3 'of the reel body 2 on which they are mounted.
A spool shaft 7 on which a spool 6 is mounted is rotatably supported via a spool 5, and an extension shaft 7 'on the side plate 1 side of the spool shaft 7 has a bearing 10.1 on a frame 3 and a side plate 1, respectively.
A pinion 12 rotatably supported via 1 is slidably fitted to the pinion 12, and an engagement portion 12 'formed at one end of the pinion 12 is mounted on the engagement portion 7 "of the spool shaft 7 as is well known. The clutch mechanism 13 is configured to be freely disengageable.

Therefore, when the handle shaft 16 is rotated in the same manner as in the conventional dual-bearing type reel, its power is transmitted via the drag mechanism 18 and the clutch mechanism 13 to the drive gear 17 and the pinion 1.
2. The fishing line is transmitted to the spool shaft 7 to rotate the spool 6 to wind the fishing line. When the clutch mechanism 13 is separated, the fishing line wound around the spool 6 is fed.

The bearings 4, 5, 10, 11, 1
Nos. 4 and 15 are made of metal, and have polyacetal (POM) and polyphenylene sulfide (PP) on their inner peripheral surfaces.
S), a resin collar 19 made of a polyamide resin or the like is detachably fixed as a unit by the elastic engagement force of the elastic locking claws 20 having cut grooves 20 ′ formed at both end edges thereof, and is unitized. The spool shaft 7, the pinion 12, and the handle shaft 16 each made of a different metal are rotatably supported via a collar 19.

In general, the materials of the reel body 2, the bearings 4, 5, 10, 11, 14, 15, the spool shaft 7, the pinion 12, the handle shaft 16 and the like which constitute the reel are as follows.

A rotary shaft cylinder 27 having a pinion 26 formed at the rear end is rotatably supported at the front of the pinion 26 by a bearing 23, and the bearing 24 rotates a pipe shaft 27 ′ integrally fitted to the rotary shaft cylinder 27. A spool shaft 29, which is freely supported and has a spool 28 attached to a tip end thereof, is inserted into the rotary shaft cylinder 27 so as to be freely movable in the axial direction.
The slider 30 fixed to the rear end is engaged with a traverse cam shaft 31 provided at a lower portion in the reel body 2.

Therefore, as is conventionally known, the pinion 26
Engages with the gear 33 of the handle rotating shaft 32 to rotate the rotor 25 via the rotating shaft cylinder 27, and at the same time, the spool shaft 29 is slid back and forth via the slider 30 by the interlocking movement of the traverse cam shaft 31 to move forward and backward. Reciprocating spool 2
