PROBLEM TO BE SOLVED: To shorten a time from the calculation of estimated torque used in controlling a line pressure of an automatic transmission to the control of the line pressure and the operation of a pulley, in particular, to cover the response delay of a hydraulic system. SOLUTION: In this shift controller for a continuously variable transmission, a target torque signal obtained on the basis of the rotation of an engine corresponding to an operating state of a vehicle and a target change gear ratio by the transmission, and an actual torque signal obtained by detecting the actual torque of the engine are input in determining the estimated torque used in controlling the line pressure, and the estimated torque is determined on the basis of a signal obtained by synthesizing these signals.
