<p>PURPOSE:To prevent the noise pollution of a traveling line by providing a sound-proof cover, which is made of metal material or nonmetal material having damping effect, in the lower surface of a fixing fitting for laying a reaction plate on a track. CONSTITUTION:A reaction plate 9 is laid between tracks, which is formed with sleepers 7, 7' on a road floor 8, through a fixing fitting 12 to form a traveling line. Next, the electromagnetic force is generated between a linear motor and the reaction plate 9 to obtain the thrust and the attraction force, and while an electromagnetic field and the noise are generated in the reaction plate 9, and the noise echoes in the inner space of the fixing fitting 12. A sound-proof cover 14 made of damping steel plate or the like is provided in the lower surface of the fixing fitting 12 to hinder the noise, and noise transmission to an opening 13 between the sleepers 7, 7' and the road floor 8 is hindered. The noise generated from the traveling line can be thereby reduced.</p> |
