Zusammenfassung:	A pulley useable with a driving belt in a continuously variable transmission, including a moveable pulley half having an integral cylinder portion integrally formed therewith by plastic working. The moveable pulley half includes an axially extending hollow shaft portion, a radially outwardly extending flange portion having a contact surface frictionally contacted with the driving belt, and the integral cylinder portion axially extending at near an outer peripheral portion of the flange portion. The plastic working includes forming a workpiece, machining the workpiece, spinning the workpiece to form the integral cylinder portion, heat-treating the workpiece and finishing the workpiece to complete the moveable pulley half.
