The present invention provides a continuously variable transmission smoothly and stably changing gears without shaking of a vehicle by preventing a flapping motion as a moving pulley surface of a driven pulley rotates in an opposite direction to the rotation direction of a belt and maintains tension of the belt when a gear is shifted in a low speed. The present invention also provides the continuously variable transmission capable of smoothly shifting the gears as a cam arm moves along a predetermined trace by a roller and smoothly corrects a radius of a driving pulley by enabling a cam arm controlling the radius of the driving pulley according to rotation speed to stably move along the roller although the rotation speed is suddenly accelerated or decelerated. |
