Abstract: The present invention provides an eccentric shaft coupling capable of facilitating desirable power transmitting between drive and driven shafts disposed in one direction and in series with each other, with a sufficient durability and without any scooping even if the amount of eccentricity between respective axes of the shafts is changed or distributed. As shown in FIG. 1, an intermediate disc 5 is provided between a drive disc 3 and a driven disc 4 which are fixed to the opposed ends of a drive shaft 1 and a driven shaft 2 disposed in one direction in series with each other, respectively. A coupling mechanism is provided respectively between the drive and intermediate discs 3, 5 and between the driven and intermediate discs 4, 5.
