[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threading rod having a thread introduction hole for introducing a thread from a reel, and an internal passage for thread insertion for guiding the thread introduced from the thread introduction hole to a tip end opening of the rod. .

[0002]

2. Description of the Related Art In a threading rod of this kind, seawater or the like may be brought into the internal path together with the yarn from the point where the thread passes through the internal path. Later, salt and the like may crystallize and increase the sliding resistance of the yarn, and may cause blisters and the like. Therefore, conventionally, a small-diameter drainage hole for discharging intruded water to the outside of the blocking rod was formed behind a fishing line introduction portion for introducing the line from the reel into the rod (for example, JP-A-6-3072).

[0003]

In the above-mentioned conventional construction, the main purpose is to drain water, and since the diameter of the rod is smaller than the inner diameter of the rod, for example, when fishing with fresh water, large algae or If garbage or the like is drawn into the internal route, the material separated from the line may accumulate not only in the internal route but also near the fishing line introduction part, and even if a drain hole is provided, drain the water. It was difficult to discharge from the hole. An object of the present invention is to provide a through rod that can discharge not only water but also other trash by forming inner and outer through holes in consideration of the diameter of the internal passage for thread insertion.

[0004]

According to the first aspect of the present invention, the center rod has a first rod portion forming an internal passage for thread insertion, and a thread introduction hole for introducing a thread from a reel. A second rod portion that forms a communication space that communicates the yarn introduction hole with the internal path, wherein the second rod portion has a diameter larger than a minimum diameter of the internal path and is connected to the outside of the communication space. The point is that the inside and outside through-holes are formed to connect. The second rod of the present invention is characterized in that the first rod portion forming an internal path for thread insertion, a thread introduction hole for introducing a thread from a reel, and the thread introduction hole and the internal path are formed. A second rod portion forming a communication space communicating therewith, and a peripheral wall surface of the second rod portion at a position corresponding to a range of a length of the yarn introduction hole along the front-rear direction; The point is that the inside and outside through-holes are formed to connect. The feature configuration of the through rod of the third invention is as follows.
In the second invention, the inner and outer through holes are formed at substantially 180 ° symmetrical positions with respect to the formation positions of the yarn introduction holes. The feature configuration of the through rod of the fourth invention is the first invention,
In the second invention or the third invention, the inner and outer through holes are elongated holes long in the front-rear direction of the rod. The feature configuration of the through rod of the fifth invention is that in the first invention, the second invention, or the third invention, the inner and outer through holes are formed in substantially the same hole shape as the yarn introduction hole. is there.

[0005]

According to the first aspect of the present invention, water, dust and the like adhering to the yarn and passing through the minimum diameter portion of the internal path, when brought into the communication space, have a larger diameter than the dust and the like. Is discharged to the outside through the inner and outer through holes having the above.

[0006]

As a result, with the structure as in the first invention, even dust and the like brought into the internal passage can be discharged to the outside of the rod through the inner and outer through holes, and the conventional structure can be achieved. In comparison, the labor required for cleaning due to accumulation of dust and the like in the communication space can be reduced. [Other functions and effects] With the construction as in the second invention, since the inner and outer through holes are located within the length of the yarn introduction hole along the front-rear direction, the communication space is formed through the yarn introduction hole. Rainwater and the like that enter the inside can be drained without staying in the communication space. Moreover, the air flow path between the yarn introduction hole and the inner and outer through-holes can be configured with the shortest distance, and the air flowing between the yarn introduction hole and the inner and outer through-holes in the communication space after cleaning the inside of the communication space can be formed. It also has the effect of accelerating drying. With the configuration as in the third invention, when the inner and outer through holes are located at 180 ° symmetrical positions with respect to the yarn introduction holes, rainwater and the like entering through the yarn introduction holes can be discharged directly through the inner and outer through holes, which is more effective. By configuring as in the fourth invention, since the shape of the inner and outer through holes is a long hole in the front-rear direction, the width may be short in the width direction while taking a large opening area, and the rod forming the inner and outer through holes may be used. There is no need to increase the diameter of the part, which is advantageous in terms of manufacturing. By configuring as in the fifth invention, since the inner and outer through-holes have the same shape as the yarn introduction hole, dust and the like having a size entering through the yarn introduction hole can be discharged to the outside via the inner and outer through holes, and Each hole can have a thread introduction function, so even if the edge of one hole is damaged and the yarn is damaged, if the reel seat can be changed, the other hole is transferred as the thread introduction hole. Can be used.
