A coupling is provided with: a pair of hubs which comprises a first hub and a second hub, the first hub and the second hub each having an inner end surface and claw sections, the claw sections being arranged on the inner end surface at intervals in the circumferential direction and protruding in the axial direction of the hub, the inner end surface of the first hub and the inner end surface of the second hub facing each other, the claw sections of the first hub being each disposed between two adjacent claw sections of the second hub, the claw sections of the second hub being each disposed between two adjacent claw sections of the first hub; and a rubber spacer which is disposed between the two opposed inner end surfaces. The product of the damping ratio of the coupling and the square root of the dynamic torsional spring constant thereof is in the range of 1.3 to 12.0. |
