A continuously variable transmission for a hybrid electric vehicle is provided to achieve various driving modes of the vehicle by properly controlling speed and torque of two motors. A first planetary gear set(PG1) is coupled to an input shaft(12) of an engine(10), and is coupled to a power input shaft of a first motor(M1). A second planetary gear set(PG2) is coupled to the first planetary gear set. First and second clutches(C1,C2) transmit the power from the first motor to the second planetary gear set through the first planetary gear set. A second motor(M2) is coupled to at least one operation element of the second planetary gear sets at its input shaft, and an output shaft(14) is coupled to any one operation element of the first and second planetary gear sets.
