  • Patent number: 6648764
    Abstract: A leaf spring type coupling is described which is provided with a first leaf spring 9 and a second leaf spring 10 that absorb a deviation in the axial center of a first rotating axis and a second rotating axis via an intermediate member 8 provided between a first shaft connection member 6 and a second shaft connection member 7, wherein a second shaft coupling shaft 7 thereron is inserted and provided between a second leaf spring 10 and the intermediate member 8 so that a protrusion 7B of the second shaft connection member 7 passes through a through-hole 10B of the second leaf spring 10, and the first leaf spring 9 is inserted and provided between the intermediate member 8 and the first shaft connection member 6. Also, the intermediate member 8 and the second shaft connection members 7 are provided between the first leaf spring 9 and the second leaf spring 10, wherein the mounting angles of both of the member 7 and 8 are deviated by 90 degrees relatively to each other about their rotating axis.
