PROBLEM TO BE SOLVED: To improve hydraulic pressure governing accuracy by a pressure regulator. SOLUTION: In a hydraulic control device provided with a pressure regulator 10 governing a input pressure by intermittently communicating an inlet port 16 with an outlet port 15 by making signal pressure Ps and output pressure Pout work to a valve element 11 so as to oppose each other to the output pressure Pout according to the signal pressure Ps, a switching mechanism 18 is provided, wherein when the signal pressure Ps is increased to a pressure lower than a maximum pressure, the output pressure pout working to a feedback port 13 is cut off, and the changing gradient of the output pressure Pout is changed in the increasing process of the signal pressure Ps by discharging pressure from the feedback port 13. |
