PROBLEM TO BE SOLVED: To provide a convenient and safety transport means for aged persons and the like in a hilly section of a residential street where a number of inclined narrow roads exist. SOLUTION: A lower face of one rail is supported by a support rod having a socket on a lower end and having narrower width than the rail, the socket is inserted in a horizontal rail receiver, two short supports are erected from a ground surface to support rail receiver on both ends, and the socket can be moved along the horizontal rail receiver. The socket is shifted right and left due to a condition of the road to be fixed, and the rail can be laid even on a small road having obstacles and cliffs. Since the rail can be position- adjusted right and left to the support, curvature of the rail can be lessened as much as possible, and a construction cost can be reduced. |
