ABSTRACT:
An overfill preventing device in an underground liquid storage tank is characterized in that a window for extending outwardly or accommodating a float is provided on a peripheral wall of a cylindrical sleeve, that an upper end of the float is pivotally attached to the cylindrical sleeve at a position above the window, and that a closure valve is mounted on the upper end of the float to open or close the cylindrical sleeve at a position above the window. Since the window for extending the float outwardly or accommodating the float inwardly is formed inside the cylindrical sleeve, the float can be firmly stored. When the float is extended outwardly from the cylindrical sleeve after installing the device of the present invention, the window is closed by a lid and the lid forms a part of the cylindrical sleeve so that construction of the space within the cylindrical sleeve necessary for liquid flow is minimized, whereby liquid is smoothly supplied into the underground liquid storage tank.
