A tonneau cover generally includes two rails and at least two plates. The two rails are adapted to be fixedly mounted at two lateral sides of a cargo bed of a truck. A first plate is fixed to the two rails. A second plate is pivotally connected to the first plate and other plates are pivotally connected one after another in the same manner. In operation, all the plates except the first plate can be operated to move along the two rails to allow the plates to overlap each other to uncover the cargo bed of the truck, or to allow the plates to be flush with each other to cover the cargo bed of the truck. The tonneau cover occupies less space and can be operated easily and conveniently.

The tonneau cover as claimed in claim 1, wherein the first link of the pivotal device is a U-shaped member, the first plate is formed with an inclined face at its rear side, and the second plate is formed with an inclined face at its front side, so as to facilitate operation of the tonneau cover. 3. The tonneau cover as claimed in claim 2, wherein the second plate is provided at its rear side with a hook for attaching the second plate to a tailgate of the cargo bed of the truck. 4. The tonneau cover as claimed in claim 3, wherein a decorative plate is provided between the first and second plates so as to cover a gap therebetween when the second plate is flush with the first plate. 5. The tonneau cover as claimed in claim 1, further comprising a third plate having a front side and a rear side and defining at least one groove at an undersurface thereof and arranged over the two rails and coupled to the second plate by at least one pivotal device including a first link and a second link provided with rollers and connected at a first pivot to the first link, wherein the first link of the pivotal device connected between the second and third plates is connected at a second pivot to the rear side of the second plate, and the rollers of the second link of the pivotal device connected between the second and third plates are located in the groove of the third plate; whereby the first link of the pivotal device connected between the second and third plates is capable of being turned about the second plate at the second pivot, and the second link of the pivotal device connected between the second and third plates is capable of being pivotally moved relative to the associated first link, such that the third plate is positioned at a level, in a vertical direction of the truck, higher than and in parallel with the second plate, so that the third plate is allowed to be moved forwardly or backwardly, along the two rails, through the rollers of the associated pivotal device moving along the groove of the third plate, so that the third plate overlaps the second plate to uncover the cargo bed of the truck, or the third plate is positioned flush with the second plate to cover the cargo bed of the truck. 6. The tonneau cover as claimed in claim 5, wherein the first link of each of the pivotal devices is a U-shaped member, the first plate is formed with an inclined face at its rear side, the second plate is formed with two inclined faces respectively at its front and rear sides, and the third plate is formed with an inclined face at its front side, so as to facilitate operation of the tonneau cover. 7. The tonneau cover as claimed in claim 6, wherein the third plate is provided at its rear side with a hook for attaching the third plate to a tailgate of the cargo bed of the truck. 8. The tonneau cover as claimed in claim 7, wherein a decorative plate is provided between the first and second plates so as to cover a gap therebetween when the second plate is flush with the first plate; another decorative plate is provided between the second and third plates so as to cover a gap therebetween when the third plate is flush with the second plate.
