ABSTRACT:
In a continuously variable belt transmission wherein each of primary and secondary pulley devices consists of a stationary pulley and a movable pulley, and wherein the movable pulley is furnished with a hydraulic servo system having a cylinder which is connected at one end with the movable pulley, and a plunger which slides liquid-tightly within the cylinder; a pulley assembly for a continuously variable belt transmission (1) comprising the fact that the end (19b) of the cylinder (19) to be connected with the movable pulley (10b) of the secondary pulley device is formed with a clinch portion (19f) whose inside diameter is made larger than the outside diameter of the sliding part (16b, 18) of the plunger (16). In connecting the cylinder (19) to the movable pulley (10b) while covering the plunger (16) which is attached to the secondary shaft (5) of the transmission (1), the oil seal ring (18) of the plunger (16) is not nibbled.
