[Known technology] In the conventional fishing rod, a plurality of cylindrical fishing rod bodies can be sequentially inserted into the fishing rod body from the fishing rod body on the front side. When fishing, each rod and body are sequentially pulled out to the front side and fitted and fixed to form a single rod body. On the other hand, when it is to be accommodated, the fishing rod body on the front side is sequentially accommodated in the fishing rod body on the root side, and the size is reduced. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the traditional draw-out fishing rod, the main rod and the main rod are adjusted. There is a certain way to change the overall length of the rod to fish. The main rod of the fishing rod treated in this way has a fitting female portion on the inner peripheral surface of the front side end portion that can be fitted into the outer peripheral surface of the root side end portion of the main upper rod having a diameter slightly smaller than that of other portions, and A tubular member is provided on the inner peripheral surface of the root-side end portion. In such a fishing rod, in a state where the main upper rod connected to the front side of the main rod is pulled out to the front side (hereinafter referred to as the "extended state"), the fitting female portion of the main rod is the end portion on the root side of the main upper rod. The outer peripheral surface is fitted, and in a state where the main upper rod is inserted into the main rod (hereinafter referred to as a "receiving state"), the cylindrical member is fitted to the outer peripheral surface of the root-side end of the inserted main upper rod. In this way, the main pole and the main upper pole can be fitted and fixed to each other, whether in the "extended state" or the "contained state", and the entire length of the pole can be changed for fishing according to the situation. The standard of this paper is applicable.

Description of the invention (2) [Questions to be solved by the invention] In this form, the overall length of the fishing rod can be adjusted by the relationship between the main rod and the main upper rod. In order to improve the mutual fitting force, the diameter is set so that the main rod is arranged inside the root side. The fitting member can precisely match the outer diameter of the root side of the main upper pole. However, when the fishing rod is used for a long time and the main upper rod and the fitting member are repeatedly installed, there is a problem that the fitting force becomes lower and lower due to mutual abrasion. Therefore, in the case of severe wear, consider replacing the fitting member with a new one to restore the fitting force. However, the fitting member is a member for completely fixing the main upper pole to the main pole, so the fitting member itself needs to be strong The ground is fixed to the main pole. Therefore, even if the fitting member is made detachable from the main pole and interchangeable, it is necessary to ensure that the fitting member has sufficient mounting force to the main pole. In addition, it is troublesome to attach and detach the fitting member inserted into the inside of the cylindrical main rod, and it is necessary to make the fitting member easy to attach and detach, and easy to attach and detach. An object of the present invention is to provide a fishing rod capable of adjusting the length of the entire fishing rod and easily maintaining the fitting force between the fishing rod bodies for a long time. [Means for solving the problem] The fishing rod according to the first invention is a fishing rod for fishing, which is formed by connecting a plurality of cylindrical fishing rod bodies having a thinner tip. The fishing rod includes: A main rod having a female thread portion on the surface and a fixing hole on the front peripheral surface of the female thread portion, a main upper rod connected to the front side of the main rod in a withdrawn form, and a fitting member arranged inside the main rod on the front side of the female thread portion 、 This paper size is applicable.

Description of the invention (8) The bottom bolt section 10 is installed. On the other hand, in the portion adjacent to the front side of the enlarged diameter portion of the main rod 1, a fitting member 31 is detachably attached. As shown in FIG. 6 in detail, the fitting member 31 is a substantially cylindrical member made of a material having the same elasticity as the above embodiment, and has an opening portion 3 1 c extending in the axial direction. A predetermined position on the outer peripheral surface has a protrusion 3 1 a. A plurality of hole portions 3 1 b are formed in the fitting member 31, and the hole portions 3 1 b are used to prevent close adhesion when being fitted into the main upper rod 2. In this fishing rod, as in the above embodiment, the fitting member 31 can be easily exchanged as needed, and the fitting force can be reduced due to the long-term use of the fishing rod. (b) In the above embodiment, although the protruding portion 1 1 b of the fitting member 11 is formed in the axial direction, as shown in Fig. 7, the protruding portion may be formed in the circumferential direction. (c) In the above-mentioned embodiment, although the fishing line can be inserted through the fishing rod, the entire length of the fishing rod can be adjusted even if it is a fishing line fishing rod. [Effects of the Invention] With the fishing rod of the present invention, the length of the entire fishing rod can be adjusted, and the fitting force of the fishing rod bodies can be easily maintained for a long time. [Illustration of the drawing] Fig. 1 is a fishing line adopting an implementation form of the present invention, which can be plugged into a fishing paper. The paper size is applicable.
