Abstract

The present invention prevents the locked state of a telescopically extensible rod by using a simple structure in a joint part. A joint part B to keep the extended state of the tip section rod 1 relative to the butt section rod 2 is composed of a straight part 2B formed on the butt end rod member 2 and having a definite constant diameter at the contacting face and a protruded part 1a formed on the tip end rod member 1 and contacting with the contacting face 2B of the straight part 2B. A conical tapered receiving face 2A is formed on the inner circumference of the butt side rod member 2 and a conical tapered contact face 1A contacting with the tapered receiving face 2A is formed on the outer circumference of the tip side rod member 1.

Description

pull-out fishing rod technical field The present invention relates to a pull-out fishing rod that can be switched to a state where the rod body on the tail side is stored in a rod body on the tail side, and the rod body on the tail side is moved from the rod body on the tail side from the stored state. The state in which the body is pulled out, and a joint portion for maintaining the state in which the body is pulled out is provided. Background technique As the structure constituting the above-mentioned coupling portion, a joint for crimping is formed on the outer peripheral surface of the tail end of the rod body on the tail side and the inner peripheral surface of the tail end of the rod body on the tail side, respectively. As for the inclined surface, when the two inclined surfaces are in contact with each other, the elongated state of the pole body on the pole side is maintained by the pressure contact between the two inclined surfaces. When adopting such a structure...
