What is claimed is: 1. A torque rod for a closure panel of a vehicle comprising: a first end portion configured to be connected to a first hinge member connected to the closure panel; a second end portion configured to be connected to a second hinge member connected to the closure panel; a fixing portion configured to be fixed to a vehicle body structure of the vehicle between the first hinge member and the second hinge member; a first coiled spring portion disposed between the first end portion and the fixing portion; and a second coiled spring portion disposed between the second end portion and the fixing portion; wherein the torque rod is unitarily formed as a one-piece member. 2. The torque rod according to claim 1 , wherein each of the first and second coiled spring portions has three coils. 3. The torque rod according to claim 1 , wherein the fixing portion extends substantially linearly between the first and second coiled spring portions. 4. The torque rod according to claim 1 , wherein the fixing portion is substantially U-shaped between the first and second coiled spring portions. 5. The torque rod according to claim 1 , wherein a first end of the first end portion and a second end of the second end portion are offset from centers of the first and second coiled spring portions, respectively. 6. The torque rod according to claim 1 , wherein the first and second coiled spring portions are disposed closer to the fixing portion than to the first and second end portions, respectively. 7. The torque rod according to claim 1 , wherein the fixing portion is coated with a protective layer. 8. The torque rod according to claim 1 , wherein the torque rod is made of a heat-treated metallic material. 9. A closure panel assembly for a vehicle comprising: a closure panel movable between a closed position and an opened position; first and second hinge members movably connecting the closure panel to the vehicle; and a torque rod connected to the first and second hinge members to facilitate moving the closure panel between the closed and opened positions, the torque rod including: a first end portion connected to the first hinge member; a second end portion connected to the second hinge member; a fixing portion engaging a vehicle body structure of the vehicle between the first hinge member and the second hinge member; a first coiled spring portion disposed between the first end portion and the fixing portion; and a second coiled spring portion disposed between the second end portion and the fixing portion; wherein the torque rod is unitarily formed as a one-piece member. 10. The closure panel assembly according to claim 9 , wherein only one torque rod extends between the first and second hinge members. 11. The closure panel assembly according to claim 9 , wherein each of the first and second coiled spring portions has three coils. 12. The closure panel assembly according to claim 9 , wherein the fixing portion extends substantially linearly between the first and second coiled spring portions. 13. The closure panel assembly according to claim 12 , wherein the fixing portion is received by a protrusion extending from the vehicle body structure. 14. The closure panel assembly according to claim 9 , wherein the fixing portion is substantially U-shaped between the first and second coiled spring portions. 15. The closure panel assembly according to claim 14 , wherein the fixing portion is received by a slot in the vehicle body structure. 16. The closure panel assembly according to claim 14 , wherein the fixing portion is received by a hook connected to the vehicle body structure. 17. The closure panel assembly according to claim 9 , wherein a first end of the first end portion and a second end of the second end portion are offset from centers of the first and second coiled spring portions, respectively. 18. The closure panel assembly according to claim 9 , wherein the first and second coiled spring portions are disposed closer to the fixing portion than to the first and second end portions, respectively.
