ABSTRACT:
A footstep guide rail (3) (rail body3a) is arranged so that a level H of a horizontal surface is set at the position obtained by adding a designated offset δ to a tangential line L of a drive sprocket (9) and the footstep guide rail (3) is provided, at its one end on an introductory side of the drive sprocket (9), with a curved part (13). At a reference position closest to the drive sprocket (9), the horizontal surface of the footstep guide rail (3) is changed to the curved part (13). Consequently, it is possible to absorb velocity unevenness of one footstep roller approaching the drive sprocket (9).
