A retractable canopy and supporting structure for mounting onto the load bed of a vehicle wherein the supporting structure may be selectively slid along longitudinally extending guide rails on opposite sides of the load bed and wherein the primary supporting structure is sufficiently stable so as to resist one side of the primary support structure member from sliding along its corresponding guide rail without there being corresponding sliding movement of the opposite end of the primary structure member on the opposite guide rail when the primary structure member is urged longitudinally along the guide rails from only one side of the load bed, and wherein when the canopy is deployed over the load bed and the primary structure latched to the rearmost end of the load bed, the canopy is maintained taut over the supporting structure by resilient springs mounting the forward end of the canopy to the forward end of the load bed or to the vehicle cab.
