Abstract: In a leg apparatus with which a supporting wheel for the magnetically levitated vehicle can be lifted up and down freely, a supporting wheel is positioned and hung by a swing arm and a lifting actuator. Usage of only the lifting actuator flat spring having a damper and coil spring or a combination thereof offer a buffer-supporting to enhance better comfortable feeling of riding. The leg can be completely retracted with a short stroke by a contracting action of the lifting actuator having the internal lock. Moreover the vehicle height can be adjusted. The leg apparatus is also designed and constructed in such a way that a damper or spring is installed inside the preventive wall against fire or foreign obstacles.

Abstract: In a tire for a levitation-type vehicle for supporting a load which varies depending upon a change in speed of the levitation-type vehicle at landing and during subsequent traveling thereof, a configuration of a crown and rigidity of the crown are set so as to have a ground-contact configuration in which, when a load of the levitation-type vehicle is equal to or less than 45% at its full load, a ratio of a ground-contact length of a pair of shoulders in a circumferential direction of the tire with respect to a ground-contact length, in the circumferential direction of the tire, of a central portion of the crown in the widthwise direction is 0.6.about.1.5. Accordingly, the tire for the levitation-type vehicle has a wide ground-contact area at an initial stage of landing and traveling.
