PROBLEM TO BE SOLVED: To provide a shift control device for a belt type continuously variable transmission capable of suppressing drop of following performance and convergence performance of actual input rotation speed to target input rotation speed. SOLUTION: The shift control device for the belt type continuously variable transmission including a hydraulic pressure chamber controlling belt winding radius of an input side pulley and an output side pulley, provided with an actuator controlling gear ratio by controlling hydraulic pressure in the hydraulic pressure chamber, and capable of executing feed forward control establishing control quantity for the actuator of the hydraulic pressure chamber and feed back control establishing control quantity for the actuator based on deviation of actual input rotation speed from target input rotation speed, is provided with a final control quantity establishing means (step S4 or step S21) establishing final control quantity by reducing integration term when integration term of control quantity in feed back control is accumulated in a direction different from control quantity in feed forward control.
