It is equipped with a freely movable plate installed between the flanges, and during power transmission, the axis of the freely movable plate is shifted to an arbitrary position by the action of a leaf spring, thereby eliminating coaxiality errors between the drive shaft side and the driven shaft side. A shaft coupling that absorbs shaft center angle errors and enables smooth power transmission. (2) The shaft joint according to claim 1, further comprising a freely movable plate provided with a slit between each connecting portion on the driving side and the driven side.
