PURPOSE: A leakage preventive structure of an automobile power steering reservoir tank is provided the solution for results of a former method that the stored oil inside a main body of a reservoir tank, by pressure, leaks out through an air hole of a leakage preventive member and stains the lower part of a reservoir cap and spreads out all over, finally a reservoir tank is polluted. CONSTITUTION: In an automobile power steering system, a leakage preventive structure comprises; a reservoir tank (60) which stores up oil in and an oil-injection part (64) is formed on the upper part of; a primary oil-suction member (80) which is inserted in an oil-injection part (64) and forms an oil hole (81) in the middle; a reservoir cap (90) which fixes on the upper part of a reservoir tank (60) and has an oil leakage preventive salient (91) on the corresponding part of an oil hole (81). Therefore when an automobile runs, a leakage preventive structure prevents the stored oil inside the main body (61) of a reservoir tank (60) from leaking to the outside through the lower part of a reservoir cap (90) and protects from polluting the outside main body (61) of a reservoir tank (60) by automobile's movement, tremor and oil pressure.
