A truck cover is provided includes a flexible cover for selectively covering and uncovering the load bed of a truck. A winding assembly is mounted on the front end of the load bed and includes a reel for winding a flexible cover. A motor drives the reel through a worm drive. An extension assembly is provided which includes a pivoted rear bail connected to the rear and of the cover and a spring bias assembly which pivots the bail to the rear of the truck so as to extend the cover over the bed. A tension assembly is provided which utilizes a tension bail over the front of the cover having legs which are attached to the rear bail so the tension bail is lowered onto the front of the cover as the rear bail unwinds the cover from the winding assembly. Each leg of the rear bail is secured to the load bed through an offset pivot through which bias forces are transmitted when the cover is wound on the winding assembly to reduce strain on the winding assembly motor.
