A CVT using a belt having improved durability is provided to prevent the load from being concentrated upon the center by differing the center direction of the centrifugal force member from the center of the driving part. The diameter of the driving par(1) of the variable pulley is changed by the centrifugal force of the driving shaft(11). The driven part(2) of the variable pulley shape is formed of the structure which is identical with the driving part. The belt(6) transmits the power transmission between the driven part and the driving part. The oil controlling part(3) controls the driving part of the variable pulley shape and the diameter of the driven part. The driving part has a space part for charging the oil. The cylindrical rotation axis(12) of the hollow tube shape is formed.
