Beschreibung
Zusammenfassung:	A power transmission shaft which alleviates phenomenon in which stress is concentrated on a specific portion of a diaphragm to improve fatigue life span. The power transmission shaft connects a power apparatus and includes a flexible coupling, which is configured by a hub unit positioned inside in a radial direction. A rim unit is positioned outside in a radial direction of the hub unit. A flexible diaphragm unit is positioned between the hub unit and the rim unit. The thickness in the axial direction of the flexible diaphragm unit, from the hub unit toward the rim unit, becomes thinner then thicker to have a minimum thickness interval. The flexible diaphragm unit has a contoured first side on one side in the axial direction and a contoured second side on the other side. The first side has a first inflection point and the second side has a second inflection point.
