PURPOSE: To reduce the outside diameter of a flywheel without reducing a maximum outside diameter of frictional phasing of a clutch disc and without confirming striking regression of a transmittable torque of the frictional clutch by constituting a flywheel, the clutch disc, or a presser plate. CONSTITUTION: A flywheel 1 of an internal combustion engine, wherein the flywheel has a reduced outside diameter. The flywheel has lugs, which extend radially inward, which lugs hold a clutch disc 8 axially from the back. It is thereby possible to arrange a fitting bolt 5 on the small mean diameter. The clutch disc 8 has a maximum and a minimum outside diameter to guarantee that it can be installed on the lugs. In particular, when this type of flywheel 1 is arranged in a flywheel 1 with two centrifugal masses, it is possible to use the radially outward space saved for an additional centrifugal mass of the primary centrifugal mass. |
