Embodiments of a cover for a truck bed are shown and described. A lever assembly rotates bi-directionally and parallel to a side of the truck bed to swing a roller above the truck bed. A tarp is attached to the truck bed and to the roller and is extended and retracted from over the truck bed when the lever assembly swings. A coiled spring inside the roller biases the roller to an extent that keeps the tarp taut when it is extended, rolls up the tarp as it is being retracted, and keeps the tarp tightly rolled after it is retracted to the one side of the truck. The lever assembly includes an arcuate member and a substantially coplanar arm. The lever assembly is bi-directionally rotated by a system in which a flexible connector has two sections that are attached to the arcuate member, extend in opposite directions around the arcuate member, and are pulled by a drive mechanism.
