Abstract: A vibration reduction structure of a high pressure hose for power steering is provided to prevent the allophones and vibration of a high pressure hose and to improve the ride comfort and N.V.H(Noise Vibration Harshness) efficiency of a vehicle by sensing the movement of a high pressure hose with an acceleration sensor and controlling the location of the hose. The vibration reduction structure of a high pressure hose(2) for power steering, comprising an input hose for supplying oil from a reservoir tank to a hydraulic pump, a hydraulic supply hose for supplying the hydraulic pressure generated by the hydraulic pump to a gear box and supplementing operating forces when steering and a return hose for returning the hydraulic pressure completely used in the gear box to the reservoir tank by making a hydraulic pump and a reservoir tank of a power steering system connected with each other, includes an acceleration sensor(10) attached to the outside of the high pressure hose to sense the location of the high pressure hose and a vibration compensator(20) attached to the opposite side to the acceleration sensor to control the vibration of the high pressure hose with electrical signals sensed by each acceleration sensor.
