DEFINITION

Classification: 474/244

Oppositely facing surfaces are on pair of discrete elements:

(under subclass 242) Subject matter wherein a pair of said drive surfaces includes one surface formed as an integral surface of one component facing toward one side of said groove, and said pair includes another drive surface spaced directly across from said one surface in a direction parallel to the longitudinal extent of the pulley* axis and formed as integral surface of a separate component facing toward the other side of the groove.
