JP 2003-61521 A (paragraph numbers [0009] [0010] and FIGS. 1 and 2)

In the balance weight as described above, it is necessary to carry to the fishing ground, so the weight is carried only and the balance weight is equipped with multiple types of balance weights with different weights. The carrying burden became heavier.
Moreover, even if multiple types of balance weights are prepared, the balance weight itself is made of metal or the like, so only one weight can function with one balance weight. In some cases, however, a weight that cannot be displayed may be required, and it may be difficult to set an optimal balance.

An object of the present invention is to provide a fishing rod that can be easily set to an optimal balance while reducing the carrying burden.

〔Constitution〕
According to a first aspect of the present invention, there is provided a fishing rod including a liquid storage portion that stores a balance weight liquid and an intake / exhaust mechanism that sucks liquid into the liquid storage portion, wherein the intake / exhaust mechanism includes the liquid The storage portion is configured to be able to expand and contract, and the liquid storage portion is a bellows-like storage portion, and a narrow tube portion including the liquid inlet is extended from the bellows-like liquid storage portion, and the bellows And the narrow tube portion is provided to protrude from the opening of the buttock end, and the bellows-shaped liquid storage portion is shrunk to enter the opening of the buttock end. When the capillary tube is retracted once, it is configured to release the contraction force on the liquid storage part and take in the liquid into the liquid storage part, and when the thin tube part is retracted into the opening in the narrow tube part Multiple displays showing the amount of liquid to be taken in Only, so that others display numerical values the indicating display which reaches the opening position of the rod butt end is configured to indicate the amount of liquid to capture said, the effects thereof are as follows.

[Function and effect]
Since a liquid storage unit that can use liquid as a balance weight has been formed, it is not necessary to carry the liquid when going to the fishing spot, but it can be procured by operating the intake / exhaust mechanism and taking the liquid from the fishing field into the liquid storage part Is possible.
In addition, since the liquid is used as a balance weight, the amount taken into the liquid storage portion can be arbitrarily set.
In other words, since the liquid storage part is formed in a storage part that can be expanded and contracted, when the storage part is once contracted and the reduced force is released to make it free, the storage part returns to its original state. Aspirate liquid.
By forming the liquid storage portion in the storage portion that can be expanded and contracted in this way, the storage portion itself has a function as an intake / exhaust mechanism, and there is no need to provide a separate mechanism for sucking the liquid.
Since the liquid storage portion is formed in a bellows shape, the liquid can be sucked from the narrow tube portion by expanding and contracting the bellows portion. In addition, since the thin tube portion is provided separately from the liquid storage portion, it is not necessary to immerse the liquid storage portion in the liquid, and the liquid suction operation can be easily performed.
When taking the liquid into the liquid storage part, the thin tube part is pushed into the inside from the opening. Then, when the liquid storage portion shrinks and the pushing force to the thin tube portion is released from that state, the contracted liquid storage portion returns to the original state and expands, and the liquid is taken into the liquid storage portion.
In this case, the numerical value indicated by the display that has just reached the open end in the state where the thin tube portion is pushed out of the displays written on the thin tube portion indicates the amount of liquid taken into the liquid storage portion.
When the angler takes in a desired amount of liquid, it is sufficient to simply push the thin tube portion until the indication indicating the desired amount reaches the open end.
As a result, it has become possible to provide a fishing rod having excellent portability and easy balance setting.

It is in the point which is comprised in the elongate body which covers the said thin tube part which protrudes from the opening part of the said butt end, and the effect is as follows.

[Function and effect]
When taking the liquid into the liquid storage part, it is necessary to switch to a state in which the thin tube part protrudes from the opening end. On the other hand, when moving to the fishing spot, it is necessary to protect the narrow tube portion protruding from the opening end. Therefore, by forming the butt plug into a long body, it becomes possible to cover the thin tube portion, and the butt plug can be effectively used.

The characteristic configuration of the invention according to claim 3 resides in that a cap body is attached to the rear end of the bottom plug, and a concave portion is formed on the inner surface of the rear end of the cap body to store the tip of the thin tube portion. The effects are as follows.
