PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of supplying hydraulic pressure corresponding to each of hydraulic actuators even when a solenoid valve that controls hydraulic pressure of each of the hydraulic actuators fails.SOLUTION: A hydraulic control device includes a first hydraulic actuator 10 and a second hydraulic actuator 9 to which pressure oil output from a hydraulic source 13 is supplied, a first oil passage 15 communicated with the first hydraulic actuator 10 and the hydraulic source 13, and a second oil passage 17 communicated with the second hydraulic actuator 9 and the hydraulic source 13. The hydraulic control device further includes a normally open type first solenoid valve 16 provided in the first oil passage 15, a normally closed type second solenoid valve 18 provided in the second oil passage 17, a third oil passage 25 communicated with the first oil passage 15 and the second oil passage 17, a throttle valve 27 provided in the oil passage 25, and a normally open type third solenoid valve 26 provided in the third oil passage 25. |
