2. Description of the Related Art In a conventional swing-type fishing rod, a plurality of tubular rod bodies can be inserted into the rod body on the rod base side sequentially from the rod body on the tip side. When fishing, each rod body is sequentially pulled out toward the tip side, fitted and fixed, and used as one rod body. On the other hand, at the time of storage, the rod body on the tip side is sequentially stored in the rod body on the rod base side to provide a compact state.

Further, there are conventional swing-out type fishing rods which are devised so that fishing can be performed by changing the length of the entire rod. The fishing rod devised in this way has, for example, a main rod having a fitting female portion on the inner peripheral surface of the tip side end and a first fitting male portion on the outer peripheral surface of the rod base side end, while being near the center in the longitudinal direction. And an upper rod having a second fitting male portion on the outer peripheral surface thereof. Then, in this type of fishing rod, in the state where the original rod connected to the tip side of the original rod is pulled out to the tip side (hereinafter referred to as "extended state"),
In a state in which the fitting female portion is fitted to the first fitting male portion and the upper rod is inserted into the original rod (hereinafter referred to as "stored state"), the fitting female portion becomes the second fitting male portion. It can be fitted.

In this way, the base rod and the base rod can be fitted and fixed to each other in any of the "extended state" and the "stored state", and the length of the entire rod is changed according to the situation. Can be done.

SUMMARY OF THE INVENTION In the conventional fishing rod capable of performing fishing by changing the entire length of the rod, as described above, since the rod bodies are fitted and fixed to each other even in the housed state, A second fitting male portion is also formed on the peripheral surface of the upper rod on the tip side. The diameter of the second fitting male portion is adjusted by partially increasing the diameter of the peripheral surface of a predetermined position in the axial direction of the upper rod and adjusting the diameter by surface polishing or the like. . However, the work of partially increasing the diameter of a part of the circumferential surface of the rod body in the axial direction and adjusting the diameter is complicated, and the cost is increased.

Further, a plurality of fishing line guides for guiding the fishing line from the reel are arranged on the peripheral surface of the fishing rod. This fishing line guide is required to sharply transmit the force applied to the fishing line from the tackle to the rod body when the fishing tackle is attached to the tip of the fishing line. In particular, in a fishing rod that can perform fishing by changing the length of the entire rod, since the rod bodies partially overlap in the stored state, the force transmission from this line guide to the fishing rod is not possible. Becomes important.

An object of the present invention is to provide at low cost a fishing rod whose length can be adjusted. Another object is to provide a fishing rod that can smoothly transmit force from the fishing line guide to the rod body.
