Disclosed is a structure for assembling a pressure pipe to an oil pump in a power steering system, for allowing the pressure pipe to guide oil discharged from the oil pump to a power boosting mechanism. The structure comprises a cylindrical connector arranged on an upper end surface of a pump body possessing a discharging port, the cylindrical connector being defined with a hollow portion which is aligned with the discharging port and a communicating hole which extends in a radial direction from a circumferential outer surface of the cylindrical connector to the hollow portion; an eye connector integrally formed with an end of a pressure pipe, the eye connector being fitted around the cylindrical connector in a manner such that the eye connector aligns the pressure pipe and the hollow portion of the cylindrical connector with each other; a cap nut threadedly coupled around an upper portion of the cylindrical connector to fasten the eye connector; and a pair of copper washers fitted around the eye connector in such a way as to be placed on upper and lower ends of the eye connector so that airtightness is maintained between the cylindrical connector and the eye connector.

1. A structure for assembling a pressure pipe to an oil pump in a power steering system, for allowing the pressure pipe to guide oil discharged from the oil pump to a power boosting mechanism, comprising:a cylindrical connector arranged on an upper end surface of a pump body possessing a discharging port, the cylindrical connector being defined with a hollow portion which is aligned with and connected downstream of the discharging port and a communicating hole which extends in a radial direction from a circumferential outer surface of the cylindrical connector to the hollow portion; an eye connector integrally formed with an end of a pressure pipe, the eye connector being fitted around the cylindrical connector in a manner such that the eye connector aligns the pressure pipe and the hollow portion of the cylindrical connector with each other; a cap nut, having a hex-head portion and a flange portion, the flange portion having a diameter approximately equal to the diameter of the eye portion, and a height approximately equal to said diameter, threadedly coupled around an upper portion of the cylindrical connector to fasten the eye connector; and a pair of copper washers fitted around the eye connector in such a way as to be placed on upper and lower ends of the eye connector so that airtightness is maintained between the cylindrical connector and the eye connector.
