PURPOSE: A dual mass flywheel of a vehicle is provided to prevent juddering when a clutch disc contacts a secondary flywheel and to increase a damping region according to change of engine torque. CONSTITUTION: A dual mass flywheel of a vehicle includes a primary flywheel(56), a secondary flywheel(60), first elastic members(62) and second elastic members(70). The primary flywheel is bolted to a crank shaft(52) of an engine, rotating together. The secondary flywheel is separated from the primary flywheel in an axial direction. A clutch disc(58) contacts or separates from an outer surface of the secondary flywheel. First elastic members are installed between the primary flywheel and the secondary flywheel, springing to a circumferential direction. Second elastic members are installed between the primary flywheel and the secondary flywheel, springing to a radial direction. Thereby, juddering is prevented by connecting the primary flywheel and the secondary flywheel with elastic members when the clutch disc contacts the secondary flywheel. A damping region increases by a dual structure of different constant in second elastic members.
