2. Description of the Related Art Conventionally, a fishing rod for inserting a fishing line into a rod pipe has a fishing line guide 6a formed on a rod pipe 3a as shown in FIG. As shown in JP-A-8-140532 shown in FIG.
There is one in which a separate fishing line guide 6 is attached to the rod tube 3a.

[0003]

In the case where the fishing line guide 6a is formed in a series as in the former, as shown in FIG. 4, a thick tape 7a is wound around a metal core, and a prepreg 1 is wound thereon. Then, a pressure tape is wound thereon, and the tape is fired. The core is removed, and the thick tape 7a is peeled off from the inner surface of the rod tube 3a to manufacture a fishing rod.

In such a manufacturing method, for example, the prepreg 1 is press-fitted into the gap d between the thick tapes 7a wound spirally, and the fishing line guide 6a is formed in a series on the rod tube 3. However, since the prepreg 1 is made to protrude at the interval d, edges are formed at both edges in the width direction of the fishing line guide 6a, and there is a possibility that the line may be damaged or cut.

In addition, the outer peripheral surface of the prepreg 1 is pressurized so that a part of the prepreg 1 is press-fitted into the gap d so that the fishing line guide 6
When a is formed, since the fibers are oriented in the prepreg 1, it is difficult for the fibers to enter the inside of the fishing line guide 6a, and the fishing line guide 6a contains only a resin component. As a result, the fishing line guide 6a becomes abrasion resistant. The property is low.

However, when a thick and reinforced line is used in a fishing rod or the like for large game fishing, the line guide 6a is severely rubbed with the line, and the line guide 6a is worn away at an early stage. There is a problem that the function cannot be exhibited for a long time. On the other hand, in the case where the separate fishing line guide 6a is attached to the inner surface of the rod tube 3a as in the latter case, as shown in FIG.
a, and the flexible tape 4a is wound so as to cover the thick tapes 7a in the axial direction, and a string is formed from above the flexible tape 4a toward the distance d between the thick tapes 7a. Insert the object 7b, wind the prepreg 1 on it,
After that, the rod pipe 3a is manufactured according to a conventional method.

However, in such a manufacturing method, a separate string-like material 7b is integrated with the rod tube 3a during the pressure molding of the prepreg 1, and the rod-like material of the string-like material 7b serving as the fishing line guide 6a is formed. There is a problem that it is difficult to increase the attachment strength to the pipe 3a, and the fishing line guide 6a is easily peeled off from the rod pipe which is essentially largely bent. The present invention has been made in view of such a problem, and an object of the present invention is to increase the abrasion resistance of a fishing line guide that projects and attaches to the inner surface of a rod pipe of a through-hole rod and to increase the attachment strength. To provide a fishing rod and a method of manufacturing a fishing rod, which can prevent the fishing line guide from being peeled off from the rod pipe, and can substantially increase the commercial value of the through rod without damaging the line. There is to try.

It is a fishing rod protruded at a distance, since a resin liquid in which fiber and resin are mixed is applied and integrally hardened on the inner surface of the rod tube to form a fishing line guide, so that the resin liquid adapts well to the prepreg, There is an advantage that the strength of attachment between the fishing line guide and the rod tube where the resin liquid is hardened can be made sufficient, and the rod tube and the fishing line guide can be sufficiently prevented from peeling off.

In addition, since the resin liquid is reinforced with fibers, the fishing line guide in which the resin liquid is hardened has a sufficient abrasion resistance, so that even if the road line is severely rubbed by the fishing line guide, it is worn. There is an advantage that the function of the fishing line guide can be maintained for a long time. That is, according to the first aspect of the present invention, in a fishing rod in which a fishing line guide is provided on the inner surface of the rod tube, the fishing line guide is prevented from being peeled from the rod tube and the wear line guide has sufficient wear resistance. There is a feature.

According to the second aspect of the present invention, since the resin of the resin liquid and the resin of the prepreg are the same, the attachment strength between the fishing line guide with the cured resin liquid and the rod pipe can be further increased, and the fishing line guide can be improved. There is an advantage that the peeling of the film can be further prevented. According to the third aspect of the present invention, since the connecting layer in which the resin liquid is cured is present on the inner surface of the rod between the fishing line guides adjacent in the axial direction, the resin liquid extends over substantially the entire surface of the rod. There is an advantage that the strength of attaching the guide to the rod tube can be further increased and the peeling of the fishing line guide can be further prevented.

In the invention of claim 4, a fishing line guide is provided on the inner surface of the rod tube formed by winding a prepreg in which fibers are impregnated with a resin around a cored bar into a cylindrical shape, at intervals in the axial direction of the rod tube. A method of manufacturing a protruding fishing rod, wherein a thick tape is wound around a cored bar at an interval in the axial direction thereof, and has a thickness greater than that of the thick tape covering the interval between the thick tapes in the axial direction. Winding a thin flexible tape, bending the flexible tape, filling the gap with a resin liquid impregnated with resin with a fiber shorter than the width of the gap, and then winding the prepreg to produce a fishing rod Therefore, the flexible tape can be bent between the thick tapes and filled with the liquid resin liquid while the same effect as that of the first aspect of the present invention can be obtained, so that both ends of the fishing line guide in the width direction can be obtained. A substantially arc-shaped chamfered portion can be formed in the There can be avoided from being formed, there is an advantage that it is possible to avoid damaging the road yarn in the fishing line guide.

According to the fifth aspect of the present invention, since the resin of the resin liquid and the resin of the prepreg are the same, the same effect as the second aspect of the invention can be obtained. According to the sixth aspect of the present invention, the resin liquid is applied also between the intervals adjacent to each other in the axial direction, so that the same effect as that of the third aspect of the invention can be obtained, but the resin liquid is applied between the thick tapes. There is an advantage that the work of filling the material becomes easy.
