Abstract:
A leaf spring coupling including:a first shaft connection member for coupling a member having a first rotating axis; a second shaft connection member that is coupled with a member having a second rotating axis and is provided with a protrusion; an intermediate member that is provided between said first shaft connection member and said second shaft connection member; and a first leaf spring and a second leaf spring, which absorb a deviation in axial misalignment of said first rotating member and said second rotating member via said intermediate member and have through holes disposed in a roughly square-shaped pattern; wherein said second shaft connection member is disposed with the protrusion thereof passing through a through-hole of said second leaf spring, to be disposed between said second leaf spring and said intermediate member; said first leaf spring being disposed between said intermediate member and said first shaft connection member; said intermediate member and said second shaft connection member being disposed between said first leaf spring and said second leaf spring, and the mounting angle of said intermediate member and said second shaft connection member in the lengthwise direction being aligned with a position defined by a diagonal line of the pattern of through holes of the first and second leaf springs and the same are angularly deviated by 90 degrees relatively to each other about the rotating axes.
