Description of the Related Art In a conventional fishing rod formed by connecting a plurality of rods, a connecting structure for connecting the rods includes a tapered cylindrical member which is attached to an end of a first rod which is a tapered cylindrical member. A structure is known in which the rod base end of the second rod body is inserted and connected. The rod-side end of the first rod body is formed to be slightly thinner than other portions to form a fitting female portion, and the rod-side end of the second rod body is formed to be slightly thinner than other portions. It is a mating male part. The inner diameter of the female fitting portion and the outer diameter of the male fitting portion are formed so as to exactly match each other, and the male fitting portion of the second rod is inserted into the female fitting of the first rod. 2
The two rods are connected.

元側に他端が挿入されるインロー芯とを有している。As described above, it takes time and effort to directly form a female part or a female part to be fitted to a rod body. Therefore, instead of such a connection structure, a connection structure called “in-row splice” is used. Proposed. The “spout joint” refers to a first rod body that is a tapered cylindrical member disposed on the rod base side, and a second rod body that is a tapered cylindrical member disposed on the tip side of the first rod body. A spigot core having a diameter smaller than that of the first rod body and the second rod body, one end of which is inserted into a tip side of the first rod body, and the other end of which is inserted into a rod base side of the second rod body. are doing.

させて連結部分の破損を招くことになりかねない。In the above-mentioned "inlay splicing", the outer diameter of the inlay core is inevitably smaller than that of the rod body when comparing the inlay core and the two rod bodies to which the inlay core is connected. . Since a reduction in the diameter of the tubular body causes a decrease in rigidity, as a result, the rigidity of the spigot core is lower than that of the rod body. This partial reduction in rigidity of the spigot core of the spigot joint prevents the gentle bending of the entire fishing rod that connects multiple rod bodies, and also causes stress to be concentrated on the spigot core, causing damage to the connecting part. It can be.

In addition, the second rod body is formed of a fiber reinforced resin having a lower elastic modulus than the first rod body. Here, the elastic modulus of the fiber reinforced resin forming the core is higher than the elastic modulus of the fiber reinforced resin forming the second rod, and the core having a small diameter is excessively large compared to the first rod and the second rod. To prevent bending. As a result, even when a large force is applied when a plurality of rods are connected to form a single fishing rod, the entire rod is not bent extremely near the connection between the first rod and the second rod. As it curves gently. In addition, it is possible to prevent stress from being partially concentrated, and it is also possible to prevent damage at the connecting portion of the rod body.
