Claims

[Scope of utility model registration request]

In a U-shaped communication tank consisting of left and right vertical tanks and a communication pipe that communicates the lower parts of these vertical tanks with each other, liquid is stored so as to form an air chamber in the upper part of each of the left and right vertical tanks. A vibration-proof tank characterized in that a partition plate is provided in a region forming a free surface of the liquid and partitioning the free surface.
