The present invention relates to a continuously variable transmission chain driver. The continuously variable transmission chain driver includes: an annular outer ring body having a plurality of teeth arranged on an outer surface thereof, and being linked with a driven sprocket by a chain connected to the plurality of teeth; an inner ring body disposed inside the outer ring body, and having a driving shaft on a center thereof; a first annular coupling part protruding laterally from a circumference of an inner surface of the outer ring body; a second annular coupling part protruding laterally from a circumference of an outer surface of the inner ring body; a plurality of left springs including a first corresponding coupling part contacting the first coupling part, a second corresponding coupling part contacting the second coupling part, and an intermediate part connecting the first and second corresponding coupling parts to each other, the plurality of left springs being disposed between the first and second coupling parts and arranged in a swirl shape; and a coupling unit connecting the first and second corresponding coupling parts of each of the leaf springs to the first and second coupling parts. Thus, the outer ring body is varied with respect to the inner ring body according to a change in the tension of the chain. |
