ABSTRACT:
A reservoir used in an automotive power steering system is provided with a first filter disposed within a reservoir body at a location between an inlet and an outlet thereof. The reservoir is further provided with a first guide member for forcing the oil flowed into through the inlet to flow toward the first filter by changing the flow direction of the oil and a second guide member for forcing the oil passed through the first filter to flow toward the outlet by changing the flow direction of the oil. The first guide member is provided with an opening, and a second filter whose mesh is finer than that of the first filter is attached to the opening so as to allow the oil to flow from the inlet to the inside space above the first filter through the second filter. On the other hand, the second guide member is formed with a second opening for allowing the oil passed through the first filter to flow toward the outlet through the second opening.
