To provide a shaft coupling having stable torque transmitting performance by smoothly absorbing an axial center difference even when existing between two shafts during rotation while sufficiently securing torsional rigidity against rotating force.

A cylinder member 6 as an intermediate 2 mounted between shaft fasteners 1a, 1b is arranged at the center and flexible members 7 are arranged on both sides. The flexible members 7 have two plate spring annular bodies 71 arranged side by side in the axial direction with their planes opposed to each other and outer periphery portions 711 joined to each other to form a bent portion 70. The flexible members 7 and the cylinder member 6 are caulked and joined to each other. Thus, the axial center difference between two shafts J1, J2 from an axial line can be absorbed by the intermediate 2 using the flexible members 7 at both ends while the torsional rigidity is strengthened in the rotating direction by the cylinder member at the center to sufficiently endure a load with rotating force. As a result, the axial center difference between both shafts connected together is smoothly absorbed even during rotation and stable torque transmission is achieved by high torsional rigidity.
