A retractable truck bed cover comprising a plurality of relatively narrow slats (12-12) which are rotatably interfitted together along their longitudinal edges by means of mating elements (26,28) so that the cover is flexible in its longitudinal direction. The slats include wheels (64) which extend from the opposite end edges thereof and which are mounted for rotation. The wheels are received into opposing side rails (36,38) which are mounted along the top edges of the truck bed. A cover retracting mechanism (18) is positioned adjacent the cab of the truck, and includes two vertical end pieces (100,102), on facing surfaces of which is located a shallow spiral track (108), which receives the wheels (64) of the succession of slats comprising the cover, permitting the cover to be conveniently rolled up upon itself.
