PURPOSE: A residual oil indicator of a power steering oil tank is provided to allow the user to check the oil amount in the oil tank without removing a level gauge cap from the oil tank. CONSTITUTION: A residual oil indicator of a power steering oil tank includes a level gauge cap, a roller, a tension coil spring, and a buoy. The level gauge cap(10) includes an observation window which is mounted on the top of a tank(1) adjacent to a tank cap(2) and connected to the outside. The roller includes a display unit to show the oil amount in the tank, and its both ends are supported on the level gauge cap so that the display unit is exposed through the observation window. The tension coil spring is combined with the roller on one end and with a support of the level gauge cap on the other and provides a return force to the roller. The buoy(50) is installed to float on the oil surface in the tank while being combined with the end of a wire(40) wound on the roller. |
