する無段変速機の変速制御装置。[Claim for Utility Model Registration] The movement of the spool of the speed change command valve is input to the spool of the speed change control valve via the link, and the speed change control valve controls the speed ratio between the driving pulley and the driven pulley according to the position of the link. In a shift control system for a continuously variable transmission, which is constructed so that the actual gear ratio is fed back and always in an equilibrium state, the position of the spool of the shift command valve is determined based on the throttle pressure corresponding to the engine load and the vehicle speed. A speed change control device for a continuously variable transmission characterized by being determined by the balance between a corresponding governor pressure and a spring that applies force to the spool.
