PURPOSE: A reservoir tank for a power steering system of a vehicle is provided to eliminate restriction of the position of the reservoir tank, and to prevent pollution from oil leakage by forming the closed reservoir tank in the power steering system. CONSTITUTION: A reservoir tank(200) of a power steering system is composed of a tank body(210) connected to an oil pump and a steering gearbox with an opening part; a piston(220) inserted to the tank body; a spring(230) pressing the piston; and a cover(240) installed in the opening part with a hole(241) connected to the tank body. An inlet(211) and an outlet(212) are connected to the oil pump and the steering gearbox. The hydraulic pipe line is simplified by eliminating restriction of installation position of the reservoir tank, and pollution of the vehicle body is prevented with restricting overflow of oil.
