PROBLEM TO BE SOLVED: To solve the problem of not forming a sound bridge, by connecting a support leg and a floor base via a peripheral side surface of a vibration control material by an adhesive film, by allowing an adhesive applied to an upper surface of an upper metallic plate to enter between a lower metallic plate and the floor base, by covering the lower metallic plate and a floor base surface, by dripping on the lower metallic plate from the upper metallic plate, without contacting with the peripheral side surface of the vibration control material. SOLUTION: This floor support leg structure for vibration control has the lower metallic plate 2 placed on the floor base 1 of the second floor of a two-storied house, the vibration control material 3 arranged on the lower metallic plate 2, and the support leg 5 erected on the vibration control material 3 and having the upper metallic plate 4 brought into pressure contact with the vibration control material 3 on the lower end. The lower metallic plate 2 is composed of a metallic doughnut plate having an outer diameter of 77 mm, an inner diameter of 40 mm and the thickness of 1.6 mm. The vibration control material 3 is composed of a disk having a diameter of 57 mm and the thickness of 15 mm, made of polyvinyl chloride-based elastomer. The upper metallic plate 4 is composed of a disk having a diameter of 77 mm and the thickness of 3.2 mm, and the support leg 5 is arranged and fixed in a rising shape in its central part.
