PROBLEM TO BE SOLVED: To provide a torque transmission device excellent in heat resistance using a damper formed of a metallic coil spring having higher heat resistance than a rubber coil spring. SOLUTION: In this torque transmission device, a drive shaft 54 and a driven shaft 10 are elastically connected, and a torque transmission path is formed to pass from the drive shaft 54 to the driven shaft 10. The torque transmission device is equipped with an inner rotor 14 integrally rotatable with one of the drive shaft 54 and the driven shaft 10, an outer rotor 36 integrally rotatable with the other of the drive shaft 54 and the driven shaft 10, and surrounding the inner rotor 14, at least one of metallic coil springs 56a, 56c disposed between the inner rotor 14 and the outer rotor 36 and extending in the circumferential direction of the inner rotor 14 and the outer rotor 36, and a projection and a projecting stripe for engaging one end of the coil springs 56a, 56c with the inner rotor 14 and engaging the other end of the coil springs 56a, 56c with the outer rotor 36.
