This relates to a foldable cover for a truck bed, particularly pickup truck beds. The foldable top includes a bed rail which may be readily secured to the truck bed and the bed rail carries a pair of transversely aligned primary support hinges which serve as the sole support for the foldable support frame. The support frame is formed of a plurality of generally U-shaped frame members with only a rearwardly extending frame member being pivotally connected to the primary hinges and the connection between lower rear ends of a front frame member being carried by forward lower ends of the rear frame member in a manner wherein the bottom ends of the forward frame member move rearwardly as the support frame is folded from an upright cover supporting position to a collapsed position whereby a cross bar of the front frame member moves substantially in a vertical plane so as to clear at all times the rear of a truck cap.
