In this escalator the step belt (4) consists of motor-driven steps (3) and free-running steps (3.1). A drive frame (15) connected with a step frame (13) serves as support for a drive unit of the motor-driven step (3), wherein the drive unit consists of a motor (17), a transmission and a brake (19). A friction wheel (20) which transmits the drive power to a travel track (21) is arranged at the transmission output, wherein a counter- pressure roller arranged in fixed position at the drive frame (15) laterally guides the step (3).
