Claims

[Scope of utility model registration request]

It is connected to the pump via a supply path and a drain path, and the working fluid discharged by the pump is returned through the supply path and the drain path, adding an auxiliary force to the manual steering force of the steering wheel and transmitting it to the steering wheel. In the power steering device, a bypass path is provided that short-circuits the supply valve and the drain path, and the flow area of the bypass path, which is in an open state when the pump is started, is continuously changed as the working fluid flows. 1. A power steering device characterized by comprising a bypass valve that changes the current state and then closes the valve.
