PURPOSE: A torsion damper is provided to reduce manufacturing costs by comprising a mass, a spring, and a damping unit in an input shaft. CONSTITUTION: A torsion damper(300) comprises a torsion bar(310), a hub(340), a mass(360), and a damping unit(370). The torsion bar is connected and fixed by a fixing unit(330). The torsion bar comprises a fastening portion(345) and performs as a torsion spring. The hub is connected to the torsion bar. The mass is comprised on the exterior surface of the hub. The damping unit reduces torsional vibration transferred from an input shaft. The damping unit comprises a pressing plate(372), a pressing spring(376), and a friction plate(374). |
