Continuously variable transmission apparatus

The present invention relates to a continuously variable transmission apparatus, which is characterized by comprising: an input shaft transferred with torque inputted from the outside; a plurality of driven gears which are arranged around the circumference of the input shaft at a certain phase difference and transferred with the power from the input shaft; a variable cam of which the turning radius can be varied by an external load; a variable input link which is coupled to and transferred with the torque of the input shaft and allows the rotation thereof; a one-way clutch which is transferred unidirectionally with the bidirectional torque to be transferred to the driven gears, respectively, and rotates the driven gears in one direction; a plurality of cam shafts which contact the one-way clutch internally or externally; and a plurality of output links, each of which one end revolves together with the variable cam around the center of rotation of the variable input link and the other ends of which are coupled to the cam shafts respectively and allow swiveling thereof.
