DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threading device used for passing a fishing line through a fishing line passage of a hollow rod.

[0002]

2. Description of the Related Art A conventional through rod has a plurality of cylindrical rods having a fishing line passage through which a fishing line can be inserted. A reel is detachably fixed to the outer periphery of the rod body on the rod base side, and a fishing line introduction port for introducing a fishing line into a fishing line passage is formed on the outer peripheral surface of the rod body on the tip side of the reel. Also,
At the tip of the tip of the pole body located closest to the tip of the rod, a line lead-out port for guiding the fishing line to the outside is provided. In such a hollow fishing rod, the fishing line from the reel is introduced into the fishing line passage inside the rod body from the fishing line introduction port, and is led out from the fishing line drawing port at the head.

[0003] In this kind of through rod, a threading tool is used to insert a fishing line into a fishing line passage. As shown in FIG. 8, the conventional threading device 100 is formed from a wire 101 formed by a plurality of strands. At the rear end of the wire 101, a line stopper 103 capable of locking a fishing line is provided, and at the tip of the wire 101, a cap 102 for preventing a wire of the wire 101 from spreading is fixed. The cap 102 is a substantially cylindrical member having a fixing hole into which the wire 101 can be inserted, and the end on the distal end side is rounded.

[0004] When a fishing line is passed through a center rod using such a threading device 100 (hereinafter referred to as "fishing line insertion operation").
First, the fishing line L is locked in the line stopper 103 of the threader. Next, the cap 102 of the threading device is inserted into the fishing line insertion passage inside the rod body from the fishing line introduction port. And threader 1
By pressing 00, it is sent to the tip side, and the cap 102
To the outside from the fishing line outlet at the tip of the rod body. After that, the threader 100 is pulled out, and the fishing line L locked by the line stopper 103 is led out from the fishing line outlet.

[0005]

When a fishing line is passed through a center rod using a threading device, it is possible to move the threading device more smoothly if the threading device passes through the center of the fishing line passage. However, the cap portion of the conventional threading device does not center the threading device particularly in the fishing line passage.

[0006] In addition, a fishing line support projection is formed on the inner peripheral surface of the fishing line passage to reduce the sliding resistance of the fishing line by supporting the fishing line in a state of being lifted from the inner peripheral surface of the fishing line passage. May be. In such a through rod,
When pulling back the threading device not in the cap side direction but in the opposite direction, the fishing line support protrusion is caught on the outer diameter step portion (see G in FIG. 8) between the cap portion and the wire, and the threading device cannot be pulled back smoothly. There may be cases.

An object of the present invention is to provide a threading device that facilitates a fishing line insertion operation.

A threading device, comprising: a bendable linear main body; and a cap connected to a tip of the main body. Further, the outer diameter of the cap portion is formed so as to increase toward the distal end side from the connection side portion with the main body portion.

In this case, the outer diameter of the cap portion is formed larger than that of the main body portion, so that the cap portion can easily pass through the center of the fishing line passage in the fishing line passage, and the entire threading device can be inserted in the fishing line passage. Centering at. In particular, the outer shape of the cap portion is formed so as to increase in diameter toward the distal end side.For example, in a boring rod in which a fishing line support projection is formed on the inner peripheral surface of the fishing line passage, the threading tool is moved in the cap side direction. Even when the fishing line is pulled back in the opposite direction, the movement of the threading device in the fishing line path is smooth.

A threading device according to a second aspect of the present invention is a threading device used for passing a fishing line through a fishing line passage inside a center rod having a fishing line introduction port at a hand side and a line outlet at a distal end. A flexible main body, and a cap connected to the tip of the main body. The ridge line in the axial direction of the portion of the cap portion connected to the main body portion is formed in an arc shape.

[0011] In this case, for example, in a boring rod in which the ridge line in the axial direction of the portion of the cap portion connected to the main body portion has an arc shape and the fishing line support projection is formed on the inner peripheral surface of the fishing line passage, Even when the threading device is pulled back in the opposite direction instead of the cap side direction, the movement of the threading device in the fishing line passage is smooth. A threading device according to a third aspect of the present invention is the threading device according to the first or second aspect, wherein the difference between the outer diameter of the end of the cap on the side of the main body and the outer diameter of the main body is 0.4 mm or less. is there.

In this case, the outer diameter difference between the cap portion and the main body portion is equal to or less than a predetermined value. For example, in a boring rod having a fishing line support projection formed on an inner peripheral surface of a fishing line passage, a threading tool is used. When pulling back in the opposite direction instead of the cap side,
It is possible to sufficiently prevent the fishing line support projection from being caught by the step between the cap portion and the main body portion, and the movement of the threading device in the fishing line passage becomes smooth.

A threading device according to a fourth aspect of the present invention is the threading device according to any one of the first to third aspects, wherein the outer periphery of one end of the cap portion is chamfered. Here, when the threading device advances in the direction of the cap portion, the chamfered portion on the outer periphery of the one end of the cap portion suppresses friction and snagging of the cap portion with respect to the inner peripheral surface of the fishing line passage, and moves the threading device. Make it smooth. In addition, as a result of chamfering, it is possible to ultimately form the cap portion into a spherical shape.

A threading device according to a fifth aspect of the present invention is the threading device according to any one of the first to fourth aspects, wherein the difference between the maximum outer diameter of the cap portion and the minimum inner diameter of the fishing line passage of the middle fishing rod is 0.4 mm or less. It is. In this case, the difference between the maximum outer diameter of the cap portion and the minimum inner diameter of the fishing line passage of the intermediate rod is equal to or less than a predetermined value, and the cap portion is sufficiently centered in the fishing line passage.
