摘要： A power steering device of an automotive vehicle, comprises an engine of the vehicle, a steering pump driven by the engine, an actuator, a control valve connected to both the steering pump and the actuator for controlling the amount and direction of power fluid supplied from the steering pump into the actuator in response to the steering operation of the steering wheel, a centrifugal clutch having an input shaft and an output shaft for receiving the power from the engine at the input shaft and transmitting the power to the steering pump from the output shaft when the vehicle speed is low or zero, and spring means for causing the centrifugal clutch to cut off the power transmission from the input shaft to the output shaft when the vehicle speed is so high that the centrifugal force of the centrifugal clutch is larger than the biasing force of the spring means.
