  "textContent": "Disclosed is a control device for a continuously variable transmission (4) that has, as forward speed change stages, a first speed change stage (32) and a second speed change stage (33). The control device comprises a coordinated speed change means (12a) that carries out a coordinated speed changing in such a manner that when the speed change stage of an auxiliary transmission mechanism (30) is about to be changed, a speed change speed of the auxiliary transmission mechanism (30) is coordinated with a variator (20) and the variator (20) is controlled to carry out a speed change in a direction opposite to that of the auxiliary transmission mechanism (30) while carrying out the speed change operation of the auxiliary transmission mechanism (30), and a torque control means (12b) that carries out a torque regulating control during the coordinated speed changing under up-shifting by the coordinated speed change means, the torque regulating control being a control for effecting a torque-up operation to a driving source (1) after effecting a torque-down operation to the driving source and including a timing through which a starting time point of a drive force gap caused by the coordinated speed changing is advanced and a timing through which an ending time point of the drive force gap is delayed.",
