PROBLEM TO BE SOLVED: To provide a liquid storage apparatus provided with liquid level measuring means whose exposure is less even when the liquid storage apparatus is filled with water and having good appearance.SOLUTION: In a liquid storage apparatus 1, liquid level measuring means 2 for measuring a liquid level in the storage device 1 is suspended from a top surface of the storage apparatus 1 to the inside and liftably arranged so as to be projected from the top surface in accordance with rise of a liquid level. The liquid level measuring means 2 is composed of measurement members 2A, 2B, the measurement members 2A, 2B can be relatively moved in parallel with a mutual length direction and a stopper 21a is attached to the outer periphery of the measurement member 2A. When a liquid reaches an optional liquid level, rise of the measurement member 2A to the top surface of the storage apparatus 1 is stopped, the measurement member 2B is raised by further rise of the liquid level, and when the liquid level reaches near the top surface, rise of the measurement members 2A, 2B is stopped and the liquid level in the storage apparatus 1 can be measured by the states of the measurement members 2A, 2B. |
