The present invention relates to a dual mass flywheel. A coupling unit, formed on a hub, is inserted into and coupled to a coupling hole of a primary flywheel. Accordingly, the hub and the primary flywheel are mutually bonded to each other in a rotation direction. A crank bolt only penetrates the coupling unit of the hub and is mounted on a crankshaft, and thus a quick response is possible by only changing a specification of the hub, when a specification of the crankshaft is changed. |
