Further the metallic plate has engaging pieces formed on a lower surface thereof at locations closer to both the stoppers and corresponding to both the edges of the elastic plate, in a manner extending downward so as to abut on the respective edges of the elastic plate. Thus the elastic plate is rigidly held by the engaging pieces of the metallic plate to resist displacement thereof, and even if the displacement occurs, further displacement is inhibited by the stoppers at both edges of the metallic plate, which ensures double safety, to thereby further enhance the maintainability of the track.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
