PROBLEM TO BE SOLVED: To wind an endless transmission wire rope for pulling and moving a mobile carriage around a driving wheel and a driven wheel rotating in a vertical plane in positions in the upper part or on the inside of a rail for running for the mobile carriage without being noticeable from the lower side and in positions parallel to the rail for running in the upper and lower parts on the vertical center line thereof, keep the endless transmission wire rope in a state without carelessly jumping out and stretch the wire rope. SOLUTION: This rail for running is obtained by continuously forming a broken circular tubular part 23 having an upward opening 22 on either one of left and right sides on the circumference in a lower end 20' of a vertical platy part 20 and protrusively forming left and right wheel carrying parts 24 and 24 at positions with left and right symmetry under the circumference of the broken circular tubular part 23.
