ABSTRACT:
A pulley device has a shaft provided at its one end with a disk extending radially outwardly therefrom, a tubular member provided at its one end with a disk extending radially outwardly therefrom and concentrically enclosing the shaft to cooperate with the disk of the shaft to define therebetween a V-shaped annular groove for a driving belt, and a roll pin extending in the shaft in the diametrical direction of the shaft so as to engage with both of the shaft and the tubular member. In order to facilitate the relative sliding movement between the shaft and the tubular member, oilless bearings are provided to both ends of the tubular member. Furthermore, an oilless bushing is disposed between the roll pin and the tubular member or the shaft to facilitate the rolling of the roll pin.
