Abstract
Four types of pulley sheaves are common with one another in that each includes a pulley forming body having a tubular portion inserted around the corresponding shaft and a main body portion extending radially outward from one side of the tubular portion in an axis line direction, the main body portion including a conical friction surface inclined to be positioned closer to the other side of the tubular portion in the axis line direction, from an inner side to an outer side in a radial direction. The tubular portion of the pulley forming bodies that forms the driving-side and driven-side fixed pulley sheaves includes a fixing hole, while the tubular portion of the pulley forming bodies that forms the driving-side and driven-side movable pulley sheaves includes a sliding slot that allows the tubular portion to move along the axis line of the corresponding shaft only within the predetermined distance.
