[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fishing rod, particularly,
The present invention relates to a hollow rod having a line introduction hole for introducing a fishing line from a reel into a path inside the rod.

[0002]

2. Description of the Related Art A centering rod has a fishing line insertion path inside the rod body and a thread introduction hole for communicating the insertion path with the outside on the hand side. In such a hollow rod, the fishing line from the reel is introduced into the path inside the rod body through the line introduction hole, and is further guided to the opening on the tip side of the rod body.

In this type of hollow fishing rod, a zoom type hollow fishing rod whose axial length of the original fishing rod is variable is disclosed in Japanese Utility Model Laid-Open No. 6-9462. This zoom type fishing rod has an internal path through which fishing line is inserted, a reel mounting portion, a thread introduction hole for introducing fishing line from a reel mounted on the reel mounting section into the internal path, a reel mounting portion and a thread introduction hole. A zoom mechanism that can change the distance between the grip and the grip is provided on the base rod. This centering rod is designed so that the distance between the reel mounting portion and the line introduction hole is adjusted by a zoom mechanism so that the angle of introduction of the fishing line into the line introduction hole is maintained within a predetermined range with low frictional resistance. Is.

[0004]

In the conventional centering rod, the introduction angle is maintained within a predetermined range by adjusting the distance between the reel mounting portion and the thread introducing hole with a zoom mechanism. For this reason, the distance between the reel mounting portion and the thread introduction hole must be within a certain range in order to maintain the introduction angle within a predetermined range, despite the provision of the zoom mechanism. That is, if it is attempted to maintain the introduction angle within a predetermined range, the distance between the reel attachment portion and the thread introduction hole cannot be changed.

An object of the present invention is to make it possible to maintain the angle of introduction into the yarn introducing hole within a predetermined range regardless of the variation in the distance between the reel mounting portion and the yarn introducing hole.

[0006]

A centering rod according to a first aspect of the present invention is a rod through which a fishing line is inserted, and has a rod body, a line guide guide, and a line guide ring. The rod body has an internal path through which a fishing line is inserted, a reel mounting portion on which a reel can be mounted, and a line introduction hole that is formed in front of the reel mounting portion and that introduces the fishing line from the reel mounted on the reel mounting portion into the internal path. And a zoom mechanism capable of changing the distance between the reel mounting portion and the thread introducing hole. The line guide is fixedly provided between the reel leg mounting portion and the line introduction hole so as to be in relation to the line introduction hole, and guides the fishing line to the line introduction hole.

Here, since the thread guide is fixedly provided in relation to the thread introducing hole, even if the distance between the thread introducing hole and the reel mounting portion is changed by the zoom mechanism, The distance to the thread guide is unchanged. Therefore,
Before the fishing line is introduced into the line introduction hole, or at the stage of being guided out of the line introduction hole, the angle of introduction of the fishing line can be regulated within a predetermined range, and the frictional resistance between the line introduction hole and the fishing line can be kept small.

A threading rod according to a second aspect of the present invention is the rod according to the first aspect, wherein the threading guide is attached to the guide portion, the opening edge portion of the thread introduction hole, and the opening edge portion of the internal path on the thread introduction hole side. The thread guide ring is further provided. Here, since the line guide ring is provided at a place where the line often contacts with the line of the line, the frictional resistance of the line can be further reduced.

The threading rod according to the invention 3 is the threading rod according to the invention 2, wherein the thread guide ring is a hard ring made of ceramic. A fishing rod according to a fourth aspect of the present invention is the rod according to any one of the first to third aspects of the present invention, wherein the line introducing hole has a line guiding guide and a fishing line passing through a rear end opening of the internal path contacting front and rear edges of the line introducing hole.
