Claims

[Scope of Utility Model Registration Claim] (1) A tank mounted on a vehicle that stores liquid whose liquid level changes in depth, and a tank that is disposed within the tank and is movably disposed within the tank to partition the inside of the tank. a separator, a changing means for changing the area covered by the separator, a detecting means for detecting the depth of the liquid in the tank, and a detecting means for detecting the depth of the liquid in the tank detected by the detecting means. A dynamic damper structure for a vehicle, comprising: control means for controlling the area covered by the separator to operate the changing means and maintain a constant sloshing motion. (2) A tank mounted on a vehicle that stores a liquid whose liquid surface depth changes, a separator disposed within the tank and movably disposed within the tank to partition the inside of the tank, and a separator formed on the separator. and an opening formed so that the shielding area gradually increases from the upper end to the lower end in the depth direction of the liquid in the tank.
