Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “In the conventional art, eccentric oscillation speed reducers are known that are provided between two members and configured to reduce the number of rotations with a predetermined reduction ratio. Such eccen tric oscillation speed reducers include an outer cylinder fixedly attached to one of the members and a carrier provided within the outer cylinder and fixedly at tached to the other of the members. The carrier is rotatable relative to the out er cylinder in response to oscillatory rotation of oscillating gears attached to eccentric portions of crankshafts.
