PURPOSE: A torsion damper for a hybrid vehicle is provided to prevent the leakage of oil contained inside the torsion damper and to improve durability based on a modified oil leakage preventive structure. CONSTITUTION: A torsion damper for a hybrid vehicle includes an inertia plate(1), a cover plate(3), a first retaining plate(5), a second retaining plate(7), a compression coil spring(9), a driven plate(11), and a spline hub(13). The inertia plate is combined with the output shaft of an engine. The cover plate is combined with the inertia plate and forms a space containing oil. The first retaining plate is in connection with the inertia plate and integratedly rotates. The second retaining plate is integratedly combined with the first retaining plate. The compression coil spring is arranged along the columnar direction of the first and the second retaining plates. The driven plate is elastically supported by a plurality of compression coil springs and receives reaction force to a rotational direction. The spline hub is combined with the driven plate and transfers driving force to a transmission.
