Claims

[Scope of utility model registration request]

a power cylinder having a piston operatively connected to a steering wheel and a pair of oil chambers formed on both sides of the piston;
A vehicle power supply comprising a four-way switching valve that is connected to each of the oil chambers, a hydraulic pump, and a reservoir tank of the power cylinder and controls hydraulic oil supplied to each oil chamber of the power cylinder in response to a handle operation. In the steering device,
A one-way valve that allows flow from the four-way switching valve to each of the oil chambers through a first flow path is provided in a pipe connecting the four-way switching valve and each of the oil chambers, and a one-way valve that responds to acceleration of the vehicle. 1. A power steering system for a vehicle, characterized in that a flow control valve is provided in parallel with a throttle valve that throttles a second flow path.
