A continuously variable transmission is provided to control a rotation ratio of a driving shaft and a second driven shaft by controlling a moving distance of a movable crank. A disk type flange(20) is fixed to one side of a driving shaft(10). A movable crank(30) is composed of a protrusion part(32) of a shape protruded on a part of a straight line part(31). A control unit(40) controls a moving distance of the movable crank. A bearing(60) supports a driven shaft(50). A universal coupling(80) connects both sides of a driving shaft(70) to the movable crank and the driven shaft. A driving unit and a second driving shaft convert a straight-reciprocating motion generated in the driven shaft into a reciprocating-rotation motion.
