Abstract: PURPOSE:To curtail gear change from outside, and to continuously change a pulley ratio according to the rotational number of a driving shaft by providing a rotational torque transmission device of the driving shaft on a sliding part of a rigid pulley of a low pressure chamber and a slide pulley. CONSTITUTION:When an engine is rotated, a driving shaft D and a bolt 16 are rotated, and by the trusting power of the bolt 16, a rotational torque is transmitted to a rigid pulley 3 or a boss part and to a guide holder 5 or a shaft part 5a. The rotational torque transmitted to the pulley 3 is transmitted to a slide pulley 4 through splines 37, 47, and is rotated synchronously with the pulley 3. When the engine exceeds a certain rotational number until the spring force of a governor spring 21 is overpowered by the centrifugal force of a fly weight 11, a servo valve 7 is moved to the right by means of the tractive fore of a spring body 9. Engine oil of a high pressure chamber 5g is thus spilled into a low pressure chamber 5h, and is discharged via an oblique hole 131 to a discharge passage 13. The pressure working the pulley 4 is lowered as a result, and the pulley 4 and a power piston 4a follow and moves to the valve 7.
