At the same time, the actual gear ratio is fed back to maintain an equilibrium state at all times, and the position of the gear shift command valve spool is determined by the balance between the throttle pressure corresponding to the engine load and the governor pressure corresponding to the vehicle speed. In a hydraulic control system for a continuously variable transmission, governor pressure is supplied to the governor pressure oil chamber of the shift command valve via an orifice, and the oil in the governor pressure oil chamber is placed closer to the governor pressure oil chamber than the orifice. A hydraulic control device for a continuously variable transmission, characterized by being provided with a relief valve that can be discharged.
