PROBLEM TO BE SOLVED: To provide a control device of a continuously variable transmission, which has a simple configuration reducing the number of components small and can secure traveling of a vehicle when abnormality is caused in only a partial drive circuit for a control valve.SOLUTION: A control device of a continuously variable transmission is equipped with a first relay (F1) which is provided between a main electric power source (34), and drive circuits (M3, M4, M5) of transmission ratio adjusting means (LS3, LS4, LS5) and a drive circuit (M1) of a first clutch adjusting means (LS1), and a second relay (F2) which is provided between the main electric power source (34), and the drive circuits (M3, M4, M5) and a drive circuit (M2) of a second clutch adjusting means (LS2). When abnormality of the drive circuit (M1) is detected, the first relay (F1) is disconnected, when abnormality of the drive circuit (M2) is detected, the second relay (F2) is disconnected, and when abnormality of the drive circuits (M3, M4, M5) is detected, both of the first relay (F1) and the second relay (F2) are disconnected. |
