PROBLEM TO BE SOLVED: To provide a liquid storage device provided with level measuring means which exposes the level measuring means little and looks good even when the liquid storage device is filled up with water.SOLUTION: In a liquid storage device 1 which hangs a long float 2 down inside from a ceiling surface of the liquid storage device 1, there are provided drop prevention means 2a for preventing the float 2 from dropping down inside the liquid storage device 1 at an upper part of the float 2 and rise suppression means 2b for suppressing rise of the float 2 on the way to a lower end of the float 2 below the drop prevention means 2a. The rise suppression means 2b is provided below the drop prevention means 2a for preventing the float 2 from dropping down inside the liquid storage device 1 and on the way to the lower end 2b of the float 2, so that a projection length of the float 2 as the level rises is set to an arbitrary one, the float 2 is exposed little, and the device looks good. |
