PROBLEM TO BE SOLVED: To improve the balance of flexural rigidity in the longitudinal direction in a spigot joint type spinning rod.;SOLUTION: The spinning rod is a spigot joint type spinning rod. The first middle rod 2 is connected to the second middle rod 3 through a spigot core 10. One end of the spigot core 10 is inserted into the tip side of the first middle rod 2, and the other end is inserted into the butt side of the second middle rod 3. The first middle rod 2 is connected to the second middle rod 3 in a state that both the middle rods are separated from each other. The longitudinally central region of the spigot core 10, not inserted into the first middle rod 2 and the second middle rod 3, has larger flexural rigidity than those of both the longitudinal end regions inserted into the first middle rod 2 and the second middle rod 3. Especially, the flexural rigidity is continuously or stepwisely distributed to have the maximum flexural rigidity at a place near to the longitudinal center and the minimum flexural rigidity at both the longitudinal ends, respectively.;COPYRIGHT: (C)2005,JPO&NCIPI
