A dual mass flywheel having a multiple torsion property is provided that the sound of gear can be decreased and the durability of parts can be improved. A dual mass flywheel(1) having a multiple torsion property comprises a first mass(5) connected to the engine output axis of the vehicles, a drive plate(20) which is connected to the second mass, and is accommodated to the first mass, a torsion ring(41) formed between the first mass and drive plate, a first compressed spring(31) compacted by the relative rotation of the drive plate and the first mass, a cup(33) which a part of the first compressed spring is inserted to, a spring guide(32) supporting one end of first compressed spring, and a second compressed spring(34) of which one end supports the flange of cup.
