Abstract
A side-wall beam is installed on a base for a guideway for a magnetic levitation vehicle. An elastic body is interposed between the side-wall beam and the base. Then, the side-wall beam is fastened to the base with a tendon on an imaginary line which extends through an intermediate portion of the elastic body in the transverse direction of the side-wall beam and which extends along the longitudinal direction of the side-wall beam. The elastic body is thereby held under compression between the side-wall beam and the base. The side-wall beam is supported on the base through the elastic body, and also fastened to the base, holding the elastic body under compression between the side-wall beam and the base. Reactive forces produced by the compression of the elastic body act to resist forces tending to cause the side-wall beam to fall over. Any displacement of the side-wall beam which may be caused by forces generated when the magnetic levitation vehicle passes can thereby be kept within a predetermined range.
