Abstract
Abstract A truck body cover includes a flexible cover and two rails each mounted along the peripheral side of the truck body, with sliding members mounted on the rails. V-shaped spring members having arms attached to the cover are pivoted on the sliding members so as to accordion the cover when the members are drawn together and tension the cover along the peripheral side when the members are drawn apart.
