Note that the degree of elasticity can be adjusted by adjusting the number of layers and elastic modulus. Further, in the illustrated example, the central region of the joint member 4 is formed to bulge in a direction perpendicular to the axial direction of the joint member 4 (the axial direction of the fishing rod 1).
