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: According to this invention, wheels are pivotally supported by a fork arm comprising a lever-type supporting component, an expandable lifting actuator having damper serially arranged to buffer and support thereof at other end end of arm of said supporting component. With this structure, a complete retraction of wheels can be achieved. Hence the supporting component can be used both as the supporting leg apparatus to vertically support the magnetically levitated vehicle and the guide leg apparatus to mechanically guide the vehicle along the guideway side wall. It is, therefore, characterized with the simple structure, light weight, small storage space, and easy to perform maintenance.
