Description

  The present invention relates to a fishing rod for fishing, and more particularly to a method for manufacturing the tip.

  In general, the tip of a fishing rod is required to have a soft tone on the tip side and a rigidity that can cope with a large amount of deflection, and on the source side, the tone is hard and lightweight. Therefore, such a tip for a fishing rod has a rod structure in which a solid rod that is a solid portion is arranged on the front side, and a hollow rod tube that is a hollow portion is connected to the original side of the solid rod. It has been.

  By the way, as such a tip for a fishing rod, a solid rod and a hollow rod tube are formed separately, and a coupling portion is formed by cutting or the like by cutting, etc., and the mutual coupling portions are bonded. After that, there is a structure in which a thread is wound / fastened to an adhesion site to form a desired strength (see, for example, Patent Document 1).

  However, the tip of the fishing rod has a problem in that it is difficult to achieve rigidity continuity with the hollow rod because the structure is determined by the material of the solid rod due to its structure. In addition, according to this, there is a problem that the manufacturability is inferior because a thread winding and threading process is required to secure the strength of the connecting portion between the solid rod and the hollow rod tube.

Therefore, a reinforcing member is formed at the base end of the solid bowl, a core metal is arranged opposite to the supply member, and a prepreg is wound around the core bar from the base end of the solid bowl to form the tip. In addition, a configuration has been proposed in which a rigidity balance is realized and the strength of the connected portion is obtained without performing the winding and threading work.
