The sharply inclined transport surface of a slat conveyor is divided into an individual conveyance surface section and a sliding surface section; and a support plate in said individual conveyance surface section supporting only one rubber tire laid flat on said individual conveyance surface section is mounted at a larger pitch in the direction of transport than the maximum diameter of the rubber tire being conveyed. A mixed-suspended state collapsing member is mounted on a frame of said slat conveyor so as to project toward said rubber tire sliding surface section. Not only is a single rubber tire separated and carried out by a support plate but also a plurality of tires not supported by the support plate but being carried upward together in the sharply inclined individual transport zone of the slat conveyor may be raised by the mixed-suspended state collapsing member which is fixedly mounted protrusively on the sliding surface section, and securely returned to the horizontal take-in zone. Therefore, in the horizontal discharge zone, the individual separation-transport apparatus can discharge the rubber tires one by one, displaying a further great effect of individual separation and transport of the rubber tires in a lump which are otherwise not easy to separate because of a great surface friction coefficient.
