PURPOSE: A frictional hub integrated continuously variable transmission improves the degree of freedom of the design thereof by forming a frictional hub integrally in a transmission for realizing a mechanism which is easily moved forward/backward. CONSTITUTION: A frictional hub integrated continuously variable transmission comprises a first frictional element(54), a second frictional element(55) and a frictional hub(56). The first frictional element(54) is mounted on a driving shaft(S) in order to form a selective coupling for transmitting a power to a screw gear(51). The second frictional element(55) is mounted on a driving shaft(S) in order to transmit a power to a driving pulley(64) of a pulley member(52) by a selective coupling. The pulley member(52) is mounted on one side of the screw gear(51). The frictional hub(56) is integrally formed with the first frictional element(54) and the second frictional element(55) in order to make a clutching operation of the element(54,55).
