DETAILED DESCRIPTION OF THE INVENTION

[0001]

This invention uses a thermoplastic resin.
Fishing rod .

[0002]

2. Description of the Related Art Conventionally , a proposal has been made , for example, in Japanese Patent Laid-Open No. 52-141377, in which a thermoplastic synthetic resin is used as a base of a rod tube material and the rod tube is deformed after molding. In the publication of the proposal, when producing a rod tube material, first, a woven fabric made of a high-strength fiber warp is laminated on a vinyl resin thin plate, and a thin laminate is heated and pressed, and the laminate is wound once. It is cut into dimensions, softened in a mold, the seam is closely adhered, welded and formed by welding, then cooled to form a rod pipe, and heated again with a mold to perform the joint of the rod pipe body. Is finished, and a fiber cloth or tape or the like for reinforcing the rod tube in the circumferential direction is wound, a room temperature curable resin is applied, and the resin is put into a mold and cured to obtain a rod tube. .

[0003] However, in the above-mentioned technique, since a thin plate-like laminate is wound into a tube, and the seam is softened and adhered to be drawn or enlarged, the seam portion peels off, the wall thickness changes, and the strength decreases. There is . Further, since the reinforcing in the circumferential direction is formed by winding and reinforcing the reinforcing fiber in a separate step, peeling from the lamination interface is liable to occur, and there is a disadvantage in that the strength is reduced. Further, since the molding step is performed many times, the efficiency is low and the cost is increased. In addition, due to the restriction of the multiple steps, a cross-sectional irregular shape having large irregularities cannot be accurately formed at a desired position of the rod pipe.

[0004]

The problem to be solved is that the joint portion of the laminate is peeled off, the wall thickness is changed, the strength is reduced, and the reinforcing fibers in the circumferential direction are peeled off from the lamination interface. Is easy to occur, the strength is reduced, and it is difficult to accurately form a cross-sectional irregular shape having large unevenness due to restrictions of many steps.

Therefore, according to the present invention, the curvature is reduced in the circumferential direction.
In areas where there is a large change, or in the longitudinal direction,
With the aim of providing a fishing rod manufactured with high precision rod pipes
You .

[0006]
