  In the said structure, there existed one which winds a reinforcement pattern in the circumferential direction, and a thing wound several times when thinking that intensity | strength is insufficient with one roll. As described above, when one roll is insufficient in strength, a plurality of windings are performed. However, when a plurality of windings are performed, the strength is improved, but the weight as a bag increases and sometimes the weight is increased.

  The objective of this invention is providing the structure which does not cause weight increase, improving the intensity | strength of a heel tip part appropriately.

〔Constitution〕
The characteristic configuration of the invention according to claim 1 resides in that a winding end portion in the mouth-wrapping reinforcing pattern is superimposed on a winding start portion, and the function and effect thereof are as follows.

[Action]
In other words, since the winding reinforcement pattern is wound so that the winding end portion overlaps the winding start portion, the portion where the winding start portion and the winding end portion overlap is equivalent to the two plies of the reinforcement pattern. In addition to the winding start portion and the winding end portion, only one ply of the reinforcing pattern is wound.

〔effect〕
Therefore, by arranging the overlapping portion of the winding start portion and the winding end portion in the portion where a large load acts, it is possible to counter the strength of the two plies of the reinforcing pattern, and the other winding portions are Since only one ply is needed, there is no weight increase for the two plies.
With such a configuration, it is possible to provide a fishing rod that can reduce the increase in weight while improving the strength.

  A characteristic configuration of the invention according to claim 2 is that, in the invention according to claim 1, the axial length of the prepreg main pattern having a length corresponding to the axial length of the housing is longer than that of the main pattern. In a fishing rod housing that is formed by winding a short prepreg mouthpiece reinforcing pattern in a state of overlapping each other at the tip end portion position of the main pattern, the winding end portion of the mouthpiece reinforcing pattern is a winding start portion. The effect is as follows.

[Function and effect]
In other words, the configuration in which the winding end portion in the mouth-wrapping reinforcing pattern is superposed on the winding start portion can provide a fishing rod that suppresses the weight increase as a rod body while enhancing the reinforcing effect.

  A characteristic configuration of the invention according to claim 3 is the invention according to claim 2, wherein the outer mouth-wrapping reinforcement pattern is wound from above the mouth-wrapping reinforcement pattern, and the winding start portion and the winding in the outer mouth-wrapping reinforcement pattern are wound. An end portion is overlapped on the circumference, and an overlap portion of the winding start portion and the winding end portion in the inner winding reinforcement pattern located on the inner side and a winding start in the outer winding reinforcement pattern located on the outer side The overlapping part of the part and the winding end part is arranged at the 180 ° position or the substantially 180 ° position opposite to each other across the shaft core of the housing. is there.
