PROBLEM TO BE SOLVED: To provide a control device of a continuously variable transmission, which can suppress fluctuation of hydraulic pressure to a hydraulic chamber in the continuously variable transmission increased in pressure receiving area.SOLUTION: A control device of a continuously variable transmission (4) comprises: a first pressure regulation part (101) regulating and supplying the hydraulic pressure of a hydraulic power source (30); a first oil passage (201) providing communication between the first pressure regulation part (101) and a first hydraulic chamber (51); a second oil passage (202) providing communication between the first oil passage (201) and a second hydraulic chamber (52); a second pressure regulation part (102) equipped between the first oil passage (201) and the second oil passage (202), regulating the hydraulic pressure supplied by the first oil passage (201) and supplying the same to the second oil passage (202); and a control part (40) controlling the first pressure regulation part (101) and the second pressure regulation part (102). The control part (40), when controlling the second pressure regulation part (102) to vary the hydraulic pressure supplied to the second hydraulic chamber (52), varies the hydraulic pressure regulated by the first pressure regulation part (101) to inhibit catching force for catching a belt (17) from becoming insufficient. |
