Abstract
A shaft coupling includes a first coupling member, a second coupling member, and a cushioning member. The first coupling member includes first protrusions. The second coupling member includes second protrusions. The cushioning member includes a plurality of radiating portions. When the first coupling member and the second coupling member are arranged coaxially and the first coupling member and the second coupling member are in an unloaded state, predetermined paired facing surfaces have a minimum clearance angle present on a radially outer side with respect to a center of the radiating portion in a radiating direction. The predetermined paired facing surfaces are at least one of first paired facing surfaces and second paired facing surfaces.
