いる。As described above, in the rod in which the auxiliary rod body fitted in the original rod is configured to be able to move backward and forward, the rear end of the rod is held by one hand at the time of extension operation, and the other rod is held. Hold the rear end of the auxiliary rod body with your hand and pull it back, then release the hand from the rear end of the original rod and gradually raise the entire rod, so you can change your hand when extending. It has a good surface that does not need to be done, and the auxiliary rod body is pulled out backward at the time of this extension operation, so it does not lift the entire rod upward, so even when increasing the total length of the rod It does not apply excessive tension to the fishing line, and since the phenomenon that the rod tip swings greatly is also suppressed, cutting the fishing line,
Alternatively, it also has a good aspect that it is difficult for fish to come off. In addition, in the case of fishing in which the decoy ayu is guided by operating the rod, such as the Ayu friend fishing, increasing the total length of the rod during guiding or when pulling out the ayu leads to good rod operation. This extension operation is quick and
From the viewpoint of performing the fishing line without applying an excessive tension, the effectiveness of the rod in the form of pulling out the auxiliary rod body inserted into the inside of the original rod to the rear as described above is recognized.

る。However, in the case where the auxiliary rod body is internally fitted to the base rod having a shape that becomes smaller in diameter toward the rear end side, since the rear end of the base rod is likely to be elastically deformed in the bending direction, the condition of the rod is likely to collapse,
In addition, this leads to the disadvantage that a material having a large diameter is not used for the auxiliary rod body. In particular, when a structure for increasing the diameter of the tip portion of the auxiliary rod body is adopted so as to frictionally hold the tip portion and the inner surface of the original rod in the contracted state, when the auxiliary rod body is extended ( During the rearward pulling operation), the large diameter portion is likely to come into contact with the inner surface of the base rod, resulting in an increase in operating resistance, and there is room for improvement. Also, with this type of rod, like the conventional example,
Even when the auxiliary rod body is operated to the end position, the frictional force acting on the contact portion without performing a special operation such as locking is effective in that the operation state is maintained from the viewpoint of performing a simple operation. Has become important. The object of the present invention is to make the condition of the part of the original rod good without impairing the good surface of the auxiliary rod body so that it can be pushed back and forth freely, and it is smooth by using the large diameter auxiliary rod body. The point is to configure a telescopic rod that allows the user to perform the withdrawal operation and easily maintain the withdrawal state.

Grasp the grip and pull the grip part 5 backwards.
You do not have to change hands like the conventional expansion rod,
Also, the whole rod is not lifted. Also, with this rod, the diameter of the base rod 2 is reduced toward the tip end side (increased toward the rear end side) .
Since it is formed in a tubular shape, it is possible to increase the bending strength on the rear end side of the base rod 2 as compared with the conventional example, and use an auxiliary rod body 3 having a larger diameter than that of the conventional example. Will also be possible. Further, in this rod, since the holding mechanism A is provided with a contact portion that exerts frictional resistance, when the auxiliary rod body 3 is operated to either the operation end (stroke end) of the withdrawal or retraction, the contact is made. The holding state is naturally reached by the frictional force acting on the part, and the state is held. Further, at the time of this withdrawal operation, it is possible to eliminate the inconvenience that the tip portion of the auxiliary rod body 3 comes into contact with the inner surface of the base rod 2 and causes an increase in the operating resistance, thereby lowering the operating resistance. It should be noted that the phenomenon that the auxiliary rod body 3 naturally reaches the holding state by the frictional force at the end of the withdrawal operation as described above does not mean that the operation is naturally prevented, and the operation of the auxiliary rod body 3 by the stopper or the like. It also means that the structure is blocked.

Make it remarkable. In addition, in the case where the core 14 is housed inside the auxiliary rod body 3, as compared with the case where the core 14 and the auxiliary rod body 3 are arranged side by side along the axial direction in a contracted state, It is possible to shorten the dimension of.
In addition, when the stroke of the auxiliary rod body 3 is set to 100 cm or less, the fisherman can easily operate up to the operation end even when the fisherman stands up the rod during actual fishing.
Further, in the case where the confirmation means C for recognizing that the auxiliary rod body 3 has been operated to the operation end portion is provided, since it can be easily recognized by the confirmation means that the auxiliary rod body 3 has reached the operation end portion, At the same time, the inconvenience of ending the operation of the rod body 3 in an insufficient state of the withdrawal operation is solved, and at the same time, an excessive operating force is applied to the auxiliary rod body 3 to damage the holding mechanism A and the like. It will be resolved.
