To provide an eccentric shaft coupling capable of transmitting rotation between rotating shafts in a state that center shafts of two rotating shafts are made eccentric and even that eccentricities of the center shafts are varied, and of materializing a simple mechanism and the minimum axial length.
In the eccentric shaft coupling, a small rotating plate 3 of an intermediate member is freely rotatably provided to a pair of rotating plates 1, 2 coupled to shaft ends of input shafts parallel with each other and arranged adjacently and oppositely to each other and to a hole 3a provided in the rotating plate 2 at a prescribed angular pitch (90°) as a coupling mechanism for transmitting rotation between the rotating plates 1, 2 in a state that the shaft centers of the rotating plates 1, 2 are moved to an arbitrary eccentric position. The rotating plate 1 is equipped with a coupling shaft 4x correspondingly provided. Both shaft centers are formed so as to be free to decenter in an arbitrary position by relative movement of the coupling shaft 4x and rotation of the intermediate member.
