A continuously variable transmission may include a shift belt apparatus and a forward/reverse control apparatus. The forward/reverse control apparatus may include a planetary gear set consisting of first and second planetary gear sets, first clutch, and first and second brakes. The planetary gear set may include a first rotation element directly connected to an input shaft so as to be always operated as an input element, a second rotation element selectively connected to the input shaft through the first clutch so as to be operated as a selective input element and selectively connected to a transmission housing through the second brake so as to be operated as a selective fixed element, a third rotation element directly connected to an output shaft so as to be always operated as an output element, and a fourth rotation element selectively connected to the transmission housing through the first brake so as to be operated as a selective fixed element.
