Has a narrow slot 35 long in the axial direction of the rod tube, and a tubular guide 47 held by an outer frame tube 37 is inserted into the hole 35 in an inclined manner. Since the presence of the hole 35 significantly lowers the strength of the rod 13, a peripheral portion including the edge of the hole 35 is formed in the thick portion 25 as shown in the drawing.
It is formed integrally with the rod tube body.

In this embodiment, as shown in FIG. 4, the thick portion 25 has substantially the same thickness as the main body portion 27 of the rod tube 13, and has an intermediate layer 29 slightly larger in diameter than the main body portion 27; An inner layer 31 integrally formed inside the intermediate layer 29;
9 and an outer layer 33 formed integrally with the outer layer 9.

The intermediate layer 29 is formed by extending the main body portion 27 of the rod tube 13, and similarly to the main body portion 27, for example, a high-strength fiber such as carbon fiber mainly composed of fibers in the axial direction is used as a reinforcing material. Formed of a composite material. Inner layer 31
Is formed of, for example, a composite material in which a woven fabric of reinforcing fibers made of glass fiber, organic fiber, or the like is used as a reinforcing material.
The outer layer 33 is formed of, for example, a composite material in which a woven fabric of high-strength fiber made of carbon fiber, glass fiber, or the like is used as a reinforcing material.

The outer frame cylinder 37 has substantially the same length as the entire length of the thick portion 25, and is fixed to the thick portion 25 with an adhesive. In this embodiment, the positioning projection 39 formed at the front end of the outer frame cylinder 37 is fitted into the positioning recess 41 of the thick portion 25. The outer frame cylinder 37 may be formed integrally with the thick portion 25. The outer frame cylinder 37 is formed with a guide hole 45 inclined from the rear end 43 toward the narrow elongated hole 35. The substantially linear tubular guide 47 is inserted and fixed in the guide hole 45. The rear end 49 of the tubular guide is located outside the rod tube 13, and the front end 51 is located inside the rod tube 13.

A jaw 53 is formed at the rear end of the tubular guide 47, and the jaw is inserted into a concave portion 55 formed at the end of the outer frame cylinder 37. It is fixed to the frame cylinder 37. An annular guide ring 57 made of a wear-resistant material such as silicon carbide, zirconia, or alumina is inserted and fixed in the recess 55. The front end 51 of the tubular guide 47 projects into the inside of the rod tube 13 after coming into contact with the tip of the narrow hole 35 of the thick portion 25. Also, on the inner surface of the front end of the tubular guide 47,
A chamfer plane or a chamfer curved surface is formed.

The center axis of the tubular guide 47 and the rod 1
The angle between the center axis 3 and the center axis is preferably 20 degrees or less, and more preferably 5 to 15 degrees. Further, the outer diameter of the tubular guide 47 is preferably 30% or less of the outer diameter of the thick portion 25. By doing so, the width of the narrow elongated hole 35 can be reduced, and the strength of the rod tube 13 is reduced. Can be prevented.

In the through fishing rod constructed as described above,
In the thick portion 25 integrally formed with the rod tube 13, a narrow elongated hole 35 having a long diameter portion in the axial direction of the rod tube 13 is formed, and an outer frame tube 37 is attached outside the thick portion 25. A substantially linear tubular guide 47 is inserted and fixed in a guide hole 45 formed to be inclined from the rear end 43 of the outer frame cylinder toward the narrow elongated hole 35, and the rear end 49 of the tubular guide is fixed. The rod tube 13

Resistance can be significantly reduced as compared with the conventional case.

That is, a thick portion 25 in which a narrow elongated hole 35 is formed is formed in a portion of the rod tube 13 except for a joint portion at a tip end portion thereof.
Since the outer frame cylinder 37 is attached to this thick portion and the tubular guide 47 is inserted through the outer frame cylinder 37, the rigidity of the fishing line introduction portion 21 of the rod tube 13 can be significantly improved as compared with the related art. . In particular, by reducing the outer diameter of the tubular guide 47, the width of the narrow elongated hole 35 can be reduced, and a large decrease in the rigidity of the fishing line introduction portion 21 can be prevented.

Further, in the through fishing rod configured as described above, the angle formed between the tubular guide 47 and the rod tube 13 can be easily reduced, and the sliding resistance of the fishing line 19 in the fishing line introducing portion 21 is reduced. Can be greatly reduced as compared with the related art. In the above embodiment, the annular guide ring 57 is disposed at the rear end of the tubular guide 47 and the chamfered portion is provided at the front end, so that the sliding resistance of the fishing line 19 can be further reduced.

As shown in FIG. 3, the position of the reel sheet 17 and the position of the fishing line introduction part 21 are formed at a predetermined distance from each other, and the rear end 49 of the tubular guide 47 is connected to the rod tube 1.
Since it is easy to form the fishing line at a predetermined distance from the three surfaces, the fishing line introduction portion 21 does not hinder the gripping of the reel sheet 17, and the fishing line 19 can be prevented from touching the hand.

Further, in the through fishing rod constructed as described above, the thick portion 25 has a multi-layered structure using a woven cloth, so that it can be used when the narrow hole 35 is processed or when the fishing rod is used. Is prevented from occurring, and even if a large stress is applied, the occurrence of tearing, cracking and the like is prevented. In the above embodiment, the fishing line introduction part 21 is formed in the rear rod pipe 13, but the present invention is not limited to this example. For example, the fishing line introduction part is formed in a rod pipe such as a middle rod. Of course, it is good.
