PURPOSE: A continuously variable transmission is provided to save energy by supplying an angular speed ratio of input to output. CONSTITUTION: A rotation driving unit is pivotally and coaxially mounted. A power transmission assembly combines two power rollers to transmit rotation force. Each power roller is frictionally combined with the inner circumference of the rotation driving unit and the rotation driven unit and transfers the rotation force of the rotation driving unit to the rotation driven unit. A plurality of power transmission assemblies are radially and coaxially arranged with regard to the rotation driving unit.
