Abstract
An oil supply means is provided to supply the center portion of a rotating part of an Oldham coupling with oil. The oil spreads from the center of rotation to the outside of the Oldham coupling and makes it possible to prevent the Oldham coupling from wearing. A recess is also provided to direct the oil supplied from an engine to the inward portion of the Oldham coupling. Accordingly, the oil is supplied all over an Oldham projection so that it is possible to prevent the frictional wearing of the Oldham projection disposed inside the Oldham coupling.
