A large diameter portion (2) provided with an uncured synthetic resin is formed on the outer surface of the guide fixing portion of the main body (1), and a large number of axial projections are formed on the outer peripheral surface of the large diameter portion (2) on the inner peripheral surface. After inserting the heat-shrinkable tube (4) having the strip (3), the tube (4) is heated and shrunk to cure the synthetic resin of the large-diameter portion (2), and the large-diameter portion (2). )
A large number of concavo-convex stripes (5) are formed on the outer peripheral surface of, and then the tube (4) is peeled off.

である。(Operation) According to the present invention, by peeling off the tube (4),
A large number of concavo-convex stripes (5) are formed on the outer peripheral surface of the large diameter portion (2), and accordingly, the large diameter portion (2) is provided with a large number of axial ridges on the inner peripheral surface of the fishing line. Simply by inserting the guide, the axial projection of the guide fits into the concave-convex portion (5) of the large-diameter portion (2), and the fishing line guide is rotated with respect to the rod body (1). It is immovably assembled.
（ 実 施 例 ） 以下本発明を図に示す実施例に従って説明する。(Examples) The present invention will be described below with reference to examples shown in the drawings.

成樹脂を備えた大径部（２）を形成するのである。In the figure, (1) is a rod body formed by winding a prepreg obtained by impregnating an uncured thermosetting synthetic resin in a high-strength fiber such as carbon fiber in a hollow shape and then press-baking the prepreg. In the embodiment shown in (1), the large diameter portion (2) provided with the uncured synthetic resin is formed on the outer surface of the guide fixing portion of the rod body (1) before pressure firing.

（２）を形成するのである。Specifically, a narrow prepreg made of the same material as the prepreg forming the rod body (1) is formed,
The narrow prepreg is wound on the outer surface of the guide fixing portion of the rod body (1) before pressure firing for 2 to 3 plies, and the rod body (1) is attached to the general surface of the rod body (1). The large-diameter portion (2) having a diameter larger than the outer diameter is formed.

ド本体（１）全体を加熱炉で加圧焼成するのである。On the other hand, a heat-shrinkable tube (4) into which the large-diameter portion (2) can be inserted and which has a large number of axial protrusions (3) formed on its inner peripheral surface.
And the heat-shrinkable tube (4) is inserted into the outer periphery of the large-diameter portion (2) as shown in FIGS. 2 and 3, and then the rod body (1) and the heat-shrinkable tube (4) are inserted. 4) A cellophane tape (not shown) is wrapped around the outer periphery of 4) to tightly bind the rod body (1), and then the entire rod body (1) is pressure-fired in a heating furnace.

ある。As a result, the heat-shrinkable tube (4) heat-shrinks as a result of the pressure firing, and as shown in FIG. 4, the axial ridges (3) formed on the inner peripheral surface of the tube (4). However, after plunging into the narrow prepreg which constitutes the large diameter portion (2) which is still uncured, the synthetic resin of the prepreg constituting the rod body (1) and the large diameter portion (2) cures. Of.

凹凸条（５）が形成されるのである。Thus, as described above, when the pressure firing of the entire rod body (1) is completed, the cellophane tape is first peeled off, and then the heat shrinkable tube (4) is also removed from the large diameter portion (2). When peeled off, as shown in FIG. 5, a large number of concavo-convex stripes extending in the axial direction are formed on the outer peripheral surface of the large-diameter portion (2) by the projection of the axial projections (3) in the heat-shrinkable tube (4). (5) is formed.

ようなこともないのである。Then, the fishing line guide (7) having a large number of axial ridges (3) provided on the inner peripheral surface is inserted into the large diameter portion (2) having the uneven ridges (5) as described above. By inserting and fitting the fishing line guide (7), as shown in FIG. 7, the axial projection (5) of the guide (7) is fitted in the concave portion of the uneven line (5) of the large diameter portion (2). The fishing line guide (4) is non-rotatably attached to the rod body (1), and the large diameter portion (2) is provided with the axial protrusion (3) of the guide (4). The wall thickness can be as thin as the depth of the recess formed between them, so that the weight of the fishing rod is hardly increased, so that the fishing rod is not out of tune.

形成するようにしてもよい。In the above embodiments, the uncured narrow prepreg is wound around the rod body (1) before pressure firing to form the large diameter portion (2), and then the rod body (1) and the large diameter portion are formed. The diameter portion (2) and the diameter portion (2) were simultaneously pressure-fired in a heating furnace, but the large-diameter portion (2) was formed by winding the uncured narrow prepreg around the outer surface of the guide fixing portion of the rod body (1) that had been pressure-fired in advance.
The heat-shrinkable tube (4) may be inserted into the outer peripheral surface of the large-diameter portion (2) and pressure-fired to form the uneven strip (5).

子が狂うようなこともないのである。(Effects of the Invention) As described above, according to the present invention, the large diameter portion (2) provided with the uncured synthetic resin is formed on the outer surface of the guide fixing portion of the rod body (1), and the large diameter portion (2) of the large diameter portion (2) is formed. After inserting a heat-shrinkable tube (4) with a large number of axial ridges (3) on the outer peripheral surface and the inner peripheral surface, the tube (4) is heat-shrinked, and the synthetic resin of the large-diameter portion (2). While curing the resin, a large number of concavo-convex stripes (5) are formed on the outer peripheral surface of the large diameter portion (2), and then the tube (4) is peeled off to form the large diameter portion (2). By simply inserting a fishing line guide having a large number of axial ridges on the inner peripheral surface, the axial ridges of the guide are fitted into the concave and convex (5) concave portions of the large diameter portion (2). Of course, the fishing line guide can be attached to the rod body so as not to rotate, and the large diameter portion (2) The thickness of the guide may be as thin as the depth of the recess formed between the axial projections of the guide. Therefore, the weight of the fishing rod can be made lighter than before, and the fishing rod is out of tune. There is no such thing.
