ABSTRACT:
The rotation of a first flywheel of a two-mass type of flywheel device is transmitted to a second flywheel via springs. Frictional connecting portion having a friction plate is provided between the first flywheel and the springs. A driven plate integral with the second flywheel is provided between the springs and the second flywheel. The friction plate is fitted at one end thereof to a cylindrical portion formed on a diametrically inner side of the first flywheel and is frictionally engaged with the first flywheel. The friction plate is engaged at the other end thereof with the springs. A spring holding plate is disposed to define an oil chamber together with the first flywheel for containing therein the springs, the frictional connecting portion, and the driven plate. The first flywheel and the spring holding plate are formed by pressing metallic plate members and the first flywheel and the spring holding plate are welded together at their peripheries for hermetically sealing the oil chamber.
