A sliding cover assembly is provided primarily for a truck cargo bed. The sliding cover assembly is mounted on the top edge of the side walls of the cargo bed and includes a plurality of longitudinal, arcuate parallel-disposed rotatably interconnected slats which slide on a low friction surface within the guide means attached to the side walls of the cargo bed. The sliding cargo assembly further includes a lockplate attached to the leading edge of the sliding cover which secures the cover to the tailgate of the cargo bed.
