ABSTRACT OF THE DISCLOSURE An endless track conveyor apparatus having steps (1, 2) is driven by a drive chain (6) circulating along an endless travelling track (A, B ---- M, N, A) consisting of an ascending section, a descending section, and U-turn sections connecting these ascending and descending sections. This endless track conveyor apparatus includes a driven medium consisting of a number of piled-up slats (50), each of which is swingably supported on a conveyor frame. This driven medium engages with teeth provided on either the upper or the lower side of a chain link of the drive chain (6) provided at the ascending section (C-D) of the travelling track. The passive medium transmits the drive power of the drive chain (6) to the conveyor frame; therefore, the endless track conveyor apparatus travels along the travelling track. On the other hand, at the descending section (J-K) of the travelling track, the load acting on the conveyor apparatus is converted into rotational motion. This rotational force is then reversed by a reversal transmission mechanism (8, 90-92, 107, 108) to transmit this rotational force to a rotational axis (105) which drives the drive chain (6).
