PROBLEM TO BE SOLVED: To easily provide an hydraulic source for an auxiliary hydraulic apparatus in a vehicle by arranging an oil circuit in which the second selector valve switches oil from the first selector valve to a coupler supplying oil to the part other than a power steering wheel and to a return circuit to an oil reservoir. SOLUTION: A solenoid valve 3 serving as the first selector valve, by which oil from a pump 2 is switched to a steering gear box 5 and to the second valve 6, is arranged in an oil circuit A connecting a discharge port 2b of the pump 2 to an input side connection port 5b of the steering gear box 5. The solenoid valve 3 is connected to the second selector valve 6, by which oil from the solenoid valve 3 is switched to an oil reservoir 1 and to a female type coupler 7, via an oil circuit B, and the second selector valve 6 is connected to the female type coupler 7. In this way, a hydraulic source for an auxiliary hydraulic apparatus in a vehicle can be obtained easily. |
