A supporter of a noise prevention panel for floors is provided to fix the support on the floor firmly even if the state of the floor is not stable by adjusting height according to a slope of a slab. A supporter(40) of a noise prevention panel(10) for floors comprises a perforated cylinder(20), and lift limit units. The cylinder is slid by self weight within predetermined upper and lower distances by inserting the supporter in the panel. The supporter is mounted to be moved down in the cylinder. The lift limit units limit the supporter in the cylinder. The lift limit units are formed with end protrusions(41a,41b). Lifting down limit protrusions(24) are formed on inner diameters of the lower part of the cylinder. A skirt(43) is formed around the upper end of the supporter. |
