and a sub-oil pump 8 driven by an appropriate rotating member 2 that rotates continuously at least while the vehicle is in a running state, and the discharge pressure of the main oil pump 7 is equal to or higher than a predetermined pressure. The steering cylinder 6 is operated by the hydraulic oil supplied from the main oil pump 7, while
When the discharge pressure of the main oil pump 7 drops below the predetermined pressure, the main oil pump 7
In a vehicle power steering device in which the steering cylinder 6 is operated by hydraulic oil supplied from the sub oil pump 8 instead of the sub oil pump 8, the sub oil pump 8 and the rotating member 2 are connected to the main oil pump. When the discharge pressure of 7 is above the predetermined pressure, the sub oil pump 8 and the rotating member 2 are separated, and when the discharge pressure is below the predetermined pressure, the sub oil pump 8 is disconnected.
and the rotating member 2 are connected by a clutch device 16 which operates on and off depending on the level of the discharge pressure of the main oil pump 7.
