Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod having an improved joint.
[0002]
[Prior art]
A fishing rod constructed so that the fitting hole of the connecting portion of the conventional fishing rod can be easily finished and can be easily released without lowering the fitting accuracy even when used for a long time is disclosed in, for example, Japanese Patent Laid-Open No. 5-37 Proposed in the gazette.
The structure of this gazette is a fitting that is formed at the tip of the first saddle member by molding the first saddle member arranged on the hand side into a cylindrical shape with a resin containing high-strength fibers such as carbon fiber and glass fiber. A resin layer containing non-high-strength fibers such as cotton and polyester is formed on the inner surface of the joint hole. As described above, the joint layer is more easily deformed than the synthetic resin-impregnated high-strength fiber layer.
[0003]
However, the above technique is simply formed by the resin layer containing non-high strength fibers such as cotton, polyester, etc.
(1) To the extent that reinforced fibers that are softer than high-strength fibers are used, the feel during the fitting operation cannot actually be improved.
(2) Conversely, if the resin layer is made softer, the feel during fitting operation can be improved, but the soft layer will be deformed by the load during use, and the joint part will bend into a letter. Or the fitted state can be easily removed.
There are disadvantages such as.
[0004]
[Problems to be solved by the invention]
The problem to be solved is because the entire inner surface of the joint pipe is formed of a resin layer containing non-high-strength fibers such as cotton and polyester.
(1) To the extent that reinforced fibers that are softer than high-strength fibers are used, the feel during the fitting operation cannot actually be improved.
(2) Conversely, if the resin layer is made softer, the feel during fitting operation can be improved, but the soft layer will be deformed by the load during use, and the joint part will bend into a letter. Or the fitting state is easily removed.
[0005]
In view of the above-described drawbacks, an object of the present invention is to provide a fishing rod that has a good feel during fitting operation, prevents the fitting state from being easily removed, and enables stable fishing rod operation. .
