ABSTRACT:
A damper disc with serial torsion spring, in which a pair of projecting hub-side flanges protruding radially outwardly are provided on a central hub, a pair of side plates fitting rotatably onto the hub and having holes extending in a disc circumferential direction are disposed on both sides of the hub-side flange, a pair of retainers having respectively a pair of retainer-side flanges fitting rotatably onto the hub and protruding in a disc radial direction are disposed in between the hub-side flange and the side plates, a coil spring extending approximately in the disc circumferential direction is interposed between the retainer-side flange and holes of side plates and the hub-side flange to resiliently couple the hub and the side plates in the disc circumferential direction; characterized by that said coil spring is composed of a high-rigidity large-diameter main spring and a low-rigidity small-diameter sub spring fitted therein, one side of the pair of retainer-side flanges has a projection protruding to one side of the sub spring contacting therewith, another side of the retainer-side flanges has a projection protruding to another side of the sub spring, thereby the projection of the retainer-side flange is adapted to compress only the sub spring at an initial stage of twisting of the disc.
