[Detailed description of the invention]

[0001]

In the present invention, a thread insertion space is formed in a rod extending from an original rod on which a reel is mounted to a head to reach the tip end opening of the ear, and the thread from the reel is inserted into the former rod. The present invention relates to a through rod having an introduction portion for introducing into a space.

[0002]

2. Description of the Related Art It is desirable to adopt a structure that meets the following requirements for a through rod. In other words, since the fishing line coming out of the tip opening of the tip changes its direction at a substantially right angle downward at the tip opening, the feeding and winding resistance of the line is large, and the smaller the rod diameter, the larger the resistance. . Therefore,
It takes a long time to drop the bait into the shelf position by putting in the device, and the time required reduces the effect of the quilt and the like, and this tendency is more remarkable as the weight is lighter.
In addition, if the resistance is increased during winding, the thread may be forcibly wound, causing thread breakage, or a discontinuous force may be applied to the fish with a sharpened needle, and the fish may be broken. In order to reduce the resistance at the distal end opening, for example, as shown in Japanese Patent Application Laid-Open No. 4-117232, a large diameter portion that smoothly expands toward the distal end opening is formed, and an inner surface of the distal opening is formed. There has been a configuration in which a wear-resistant guide ring for guiding a yarn is mounted, and an R surface is formed on the inner surface on the distal end side of the guide ring to reduce the movement resistance to the yarn.

[0003]

With such a configuration, the fishing line gradually changes its direction from the minimum diameter portion of the enlarged diameter portion toward the guide ring, and is smoothly guided by the R surface of the guide ring. The thread is moved out of the opening at the tip and does not change its direction at a substantially right angle, so the movement resistance against the thread is reduced. Is strongly pressed against the inner surface of the smallest diameter part when changing its direction,
The movement resistance in that part has not been reduced, and the resistance has also damaged the inner surface of the rod, so that further improvements have to be made. In the above case, it was stated that it was necessary to reduce the movement resistance to the yarn at the tip opening of the tip, but the part where the movement resistance to the yarn was large was the introduction part for introducing the yarn from the reel, Had similar problems. The purpose of the first invention is to reduce the movement resistance to the yarn by forming an enlarged diameter portion at the tip of the rod and rationally adding a guide ring while suppressing a sudden change in the direction of the yarn. The point is to provide what can be done.

[0004]

According to a first aspect of the present invention, a tip portion of a tip is enlarged toward a tip opening to form a large diameter portion, and an inner surface of the tip opening portion of the large diameter portion. A first guide ring for guiding a fishing line having a smaller diameter than the inner diameter of the distal end opening and having high wear resistance, and an inner diameter smaller than the inner diameter of the smallest diameter portion in the enlarged diameter portion at a position rearward from the first guide ring. The operation and effect of the second guide ring are as follows.

[0005]

In other words, the fishing line introduced to the tip is guided by the inner surface of the second guide ring and the inner surface of the first guide ring, and exits through the opening at the tip. Therefore, there is no contact with the inner peripheral surface of the enlarged diameter portion and the inner surface of the minimum diameter portion where the enlarged diameter portion starts, so that the movement resistance can be suppressed. In addition, since the fishing line maintains the state of gradually changing its direction due to the difference between the inner surface diameter of the first guide ring and the inner surface diameter of the second guide ring, the movement resistance on that surface is suppressed. I have.

[0006]

Therefore, the direction of the fishing line is gradually changed when the fishing line exits the tip opening. The tip opening for setting the changing state by minimizing the contact area with the line as much as possible. By arranging the first and second guide rings respectively near the minimum diameter portion of the enlarged diameter portion behind it, direct contact with the rod material can be avoided, the movement resistance to the fishing line can be further reduced, and the rod can be further reduced. The inner rod can be provided with a through rod that can prevent the inner surface from being damaged.

[0007] The object of the second invention is to provide, in addition to the object of the first invention, a structure in which a guide ring is rationally added to the introduction portion to further reduce the movement resistance to the yarn. is there.

[0008]

According to a second feature of the present invention, a sleeve for guiding a yarn is provided at the introduction portion, and a smaller inside diameter than the yarn introduction port is provided at the yarn introduction port of the sleeve. A third guide ring for providing a yarn guide having a high abrasion resistance, and a fourth guide ring for a yarn guide having a smaller inner diameter than the yarn discharge port and having a high abrasion resistance at the yarn delivery port of the sleeve. Is attached, and the operation and effect are as follows.

[0009]

[Function] In addition to the function of the first invention, the following function is provided. That is, the yarn extended from the reel is guided by the third guide ring when introduced into the sleeve, and guided by the fourth guide ring when exited from the sleeve. Is avoided, and movement resistance is reduced.

[0010]

[Effects of the Invention] Therefore, the movement resistance can be reduced by the guiding action of each guide ring at the introduction portion where the fishing line largely changes direction and at the enlarged diameter portion of the tip, and the loading time of the device to the shelf position can be reduced even with a light weight. At the same time, it has become possible to provide a through rod that is easy to produce a maquie effect and less likely to catch a fish caught by a needle.

[0011]
