ABSTRACT:
A valve for detecting a liquid surface used in a fuel tank is formed of a valve body having an orifice at an upper part thereof, a plurality of bottom through-holes formed at a bottom part thereof, and a plurality of surrounding wall through-holes formed at a surrounding part thereof; a valve member movably disposed inside the valve body to close the orifice; and an urging member for moving the valve member in cooperation with buoyancy of the valve member so as to close the orifice. In the valve of the invention, the diameter of the orifice is set to be larger than the diameter of the bottom through-holes, and also larger than a diameter of the surrounding wall through-holes. Therefore, the orifice can be prevented from being clogged by foreign substances.
