PROBLEM TO BE SOLVED: To three-dimensionally interrupt the transmission of a force by forming a peripheral wall air cushion chamber between the level of a hydraulic fluid penetrated into a recessed part and the top part inner surface of the recessed part within the dovetail groove-like recessed part provided on the inside wall of a liquid tank or the circumferential wall of a floating body. SOLUTION: A surrounding wall 1b is protruded down from the bottom part of a floating body 1 so that a bottom air cushion chamber 5 is formed between the bottom lower surface 1a of the floating body 1 and the level 3a of a hydraulic fluid 3, and the circumference of the bottom air cushion chamber 5 is surrounded by the surrounding wall 1b. A dovetail groove-like recessed part having a vertical wall 7a is formed on the inside wall of a liquid tank A, and a circumferential wall air cushion chamber 4 is formed between the level 3b of the hydraulic fluid 3 penetrated into the recessed part and the top inner surface 7b of the recessed part. To the vertical vibration of a ground 6, the air cushion of the bottom air cushion chamber 5 formed along the lower surface of the bottom part of the floating body 1 works to interrupt the transmission of the force to the floating body 1.
