An improved sliding cover assembly for converting the open body of a truck, or the like, to a closed body. The assembly comprises an articulated-type cover slidably mounted in a pair of parallel tracks of C-shaped cross-section, each of the said tracks having a lengthwise coextensive channel communicating with the interior space of the open body. The cover includes a plurality of rectangular panels successively disposed adjacent to one another and extending across said open body. Each panel includes a first semi-cylindrical edge portion and a second, semi-cylindrical edge portion having a radius larger than the radius of the first edge portion, said first edge portion being concentric with, and rotatably received by, said second edge portion of the adjacent panel, the successive panels preferably being alternately wide and narrow, whereby the cover may be wound into a space-saving rolled configuration for storage when the cover is slid to its open position. a rewind tube is mounted on two pinch blocks fixed to the forward end of the open body and on opposite sides thereof. A spring cover tube with a guide wheel at each end is rotatably circumposed about the rewind tube. The forwardmost panel of the cover is attached to the guide wheels such that translational motion of the cover corresponds to rotation of the guide wheels and the spring cover tube. A coil spring having one end attached to the rewind tube and its other end attached to one guide wheel urges the cover to its open position.
