PROBLEM TO BE SOLVED: To provide a soundproof structure for a rail that can firmly fix a covering member to a rail, can be easily manufactured and installed, and can improve a soundproofing effect. A right covering member 8a is mounted on the right side surface of the rail R, and a left covering member 8b is mounted on the left side surface of the rail R. Thereafter, the right holding member 11a is attached to the right covering member 8a and the left holding member 11b is attached to the left covering member 8b with a predetermined interval in the length direction of the rail R. Next, the bolt 11h is inserted into the through holes 11f and 11g, and the nut 11i is attached to the bolt 11h to connect the right holding member 11a and the left holding member 11b. For this reason, even if the covering member 8 becomes thick and the weight increases, the covering member 8 can be firmly fixed to the rail R by the fixing member 11. As a result, the vibration generated in the rail R is reduced and the sound radiation from the rail R is suppressed, so that the soundproof damping effect can be improved. [Selection] Figure 3 |
