接続部を接続したりしている。(Prior art) Conventionally, when threading a fishing rod made of prepreg made of high-strength fiber impregnated with synthetic resin, a cylindrical adapter with a thread on the outer or inner periphery is used, and this adapter is attached to a pre-formed fishing rod. The butt plug is fixed to the butt end or intermediate connection part of the fishing rod with adhesive, and the butt plug is attached to the fishing rod or the connection part is connected to the fishing rod via the adapter.

つた。(Problems to be Solved by the Invention) However, since this conventional method uses a cylindrical adapter formed separately from the fishing rod, it not only increases the weight of the fishing rod, but also causes problems with the fishing rod. However, there is a problem in that it is difficult to install screws at fixed positions, and while the fishing rod is used for a long period of time, the adhesive may deteriorate and the adapter may naturally come off from the fishing rod. There was a problem with the adapter becoming loose at the joint with the fishing rod.

きるようにしたのである。 The present invention solves the problems in the conventional method that the provision of threads increases the weight of the fishing rod, that it is difficult to provide threads at certain locations, and that adapters with threads fall off or rattle. The idea was to eliminate the conventional adapter and use a tape made of high-strength fiber impregnated with synthetic resin, and this tape forms a thread that is integrated with the rod body that makes up the fishing rod. , the increase in weight is smaller than that using the adapter, the weight of the threaded fishing rod can be made lighter, the thread can be reliably formed in a fixed location, and it can be used for a long period of time. However, we have made it possible to position the connection state of the threaded part.
