PROBLEM TO BE SOLVED: To provide a torque damper which achieves lower rigidity and improves the damping factor for torque fluctuations thereby attaining sufficient vibration absorption characteristics.SOLUTION: A torque damper device 10 includes: a clutch piston 11 to which torque of an engine is input; and a damper spring which may absorb fluctuations of torque input from the clutch piston 11. A driving force of the engine is transmitted to the torque damper device 10 through the clutch piston 11 and the damper spring. The damper spring includes a first separate body member 14 and a second separate body member 15 which are composed of multiple coil springs (S1 to S3) disposed over a circumferential direction of the clutch piston 11, are disposed at spaces between the damper springs (S1 to S3), and may rotate independently of each other when the torque of the engine is transmitted. |
