PROBLEM TO BE SOLVED: To provide a transmission device of a continuously variable transmission allowing a variable driving pulley to be movable smoothly and surely by a simple worm gear only, and using an easy-to-interlock V-belt. SOLUTION: This transmission device of a continuously variable transmission using a V-belt comprises a variable driving mechanism moving a variable driving pulley 2 along a drive shaft 4 by a screw mechanism formed of the variable driving pulley 2 in a drive pulley and a sun gear 10 with screw, a plurality of planetary gears meshing with the sun gear with screw and disposed at equal intervals a sliding annular gear 14 formed in a worm wheel 13 meshing internally with these planetary gears and having an outer periphery meshing with a worm 12 for variable operation, a sun gear 15 fixed to the other end part of the drive shaft, a fixed internal surface gear 16 fixed to a device body positioned concentrically with the sun gear, a plurality of planetary gears meshing with and installed between the sun gear and the fixed internal surface gear and sharing the shaft with the plurality of sun gears with screw, and a planetary frame 19 supporting these plurality of shafts and controlling the disposed angle of each shaft.
