ABSTRACT:
An elastic shaft coupling and a manufacturing method of an element of the coupling, which realize reduction of the manufacturing cost while maintaining a sufficient strength of the coupling. The elastic shaft coupling has a coupling element which is formed by interposing between a joint member and a hollow shaft member an elastic member for flexing and deforming upon a relative rotation therebetween and forming stopper portions for restricting the relative rotation within a predetermined amount respectively on the joint member and the hollow shaft member. The stopper portion on the hollow shaft member side is formed by plastically processing the end portion of the material of the hollow shaft member into a flange shape.
