The soundproof members 4 are mounted on the left and right sides of the rail R and the insulation member 7e is nipped in between a fixing part 6a of a hard elastic member 6 and the supporting body 1. Next, the washer 7d is mounted on the tightening bolt 7b, and the tightening nut 7c is mounted and tightened on the tightening bolt 7b. As a result, the soundproof member 4 is firmly fixed on the supporting body 1 by the fixing member 7 while an upper face and a side face of a bottom part R2of the rail and a belly part R3of the rail are covered with the soundproof member 4.
