Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an intermediate fishing rod that inserts a fishing line inside a rod tube and guides it to the tip of the rod.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as a centering fishing rod of a swing-out type, which guides a fishing line by inserting a fishing line inside a rod tube, there is, for example, Japanese Utility Model Publication No. 63-34525. In the medium-through fishing rod of the above publication, the diameter of the front middle rod is smaller than that of the former rod. Therefore, the inner diameter of the thread guide ring fixed in the butt plug screwed into the rear portion of the rod pipe is the rod pipe. The diameter is smaller than the inner diameter. On the other hand, when the fishing line wound on the spool of the reel attached to the fishing rod is pulled out to the tip of the rod through the inside of the rod tube, the fishing line wound on the spool has a curl, so the inside of the rod tube Therefore, it is difficult to form a straight line, and it becomes a spiral and passes while hitting the inside of the rod tube. Therefore, when the fishing line passes, the fishing line hits the thick side surface of the fishing line annulus and the inner circumference of the small diameter rod pipe, and is easily scratched and scratched, and the frictional resistance increases, so that the fishing line can be smoothly pulled out from the rod tip. There were no drawbacks.

[0003]

[Problems to be solved by the device]

 The problem to be solved is that in the middle-through fishing rod in which the small diameter rod pipe is successively joined to the front side of the large diameter rod pipe, the fishing line is attached to the rod tail of the small diameter rod pipe or the small diameter rod pipe. This is because the inner circumference is liable to be scratched and scratched, the frictional resistance is increased, and the fishing line cannot be pulled out smoothly from the tip of the rod.

In view of the above-mentioned drawbacks, an object of the present invention is to reduce the difference in inner diameter of the rod pipe before and after joining to prevent an increase in frictional resistance caused by the fishing line hitting the rod pipe end or the fishing line guide. The purpose is to provide a fishing rod with which fishing line can be smoothly put in and taken out.

[0005]

[Means for solving the problem]

 The present invention is a hollow fishing rod that joins a plurality of rod pipes, wherein the inner diameter of the joint portion of one rod pipe is large and the inner diameter of the non-joint portion is small, and the inner diameter of the joint portion is And the inner diameter of the non-joint portion are formed in a taper shape or a step shape larger than the inner diameter taper of the non-joint portion, and the inner diameter of the joint portion of the one rod tube The rod pipes are detachably joined, and the inner diameter of the non-joined part of the one rod pipe and the inner diameter of the other rod pipe are made to be close to each other, and the inner diameters of the rod pipes project from the inner diameters of both rod pipes. The gist is that a fishing line guide is provided.

[0006]

[Action]

 At the stepped portion 1e, the inner circumference 1b of the front side one of the rod pipes 1a is formed with a large inner diameter 1b and the inner circumference 1d of the non-joined portion 1c is formed with a small inner diameter d1. The inner circumference 2b of the joining portion 2a of the other rear side rod tube 2 joined to the above can be formed to have a relatively large diameter, and the inner circumference 1d inner diameter d1 of the non-joining portion 1c and the other rear side rod can be formed. Since the inner diameter d2 of the inner circumference 2b of the joint portion 2a of the pipe 2 is formed to have an approximate inner diameter, the fishing line 4 inserted into the inner circumference 1d, the inner circumference 2b, and the inner circumference 3a has a spiral shape. Even if the fishing line 4 is inserted, the degree to which the fishing line 4 hits the inner circumference 1d, the inner circumference 2b, and the inner circumference 3a and receives the frictional resistance is reduced.
