PROBLEM TO BE SOLVED: To provide a support leg structure of a floor for vibration control in a bathroom and a double floor. SOLUTION: The support leg structure of a floor for vibration control is provided with a vibration proof material 3 put on the floor base 1 of the second floor of a two story house and a support leg 5 having the upper metallic plate 4 erected on the vibration proof material 3 and kept in a pressure contact with a vibration proof material 3. The vibration proof material 3 is made of a polyvinyl chloride elastomer and formed of a doughnut plate of 57 mm in outer diameter, 40 mm in inner diameter, 10 mm in thickness. The upper plate 4 is formed of a disk of 57 mm in diameter, 3.2 mm in thick and in the central part, a support leg 5 is disposed in a rising shape and fixed. The plate 4 is disposed on the material 3 so as to cover the doughnut hole 8. The pressure area of the material 3 is 12.9 cm<SP>2</SP>. The spring constant of the material 480 N/mm in 500 N load. The shock sound generated on the ground can be effectively prevented from transmitting downstairs. Since the vibratioproof material is more excellent in the load resistance. when a large load exerts on a floating floor like an upstair bathroom or double floor, sink of the floor is prevented.
