ABSTRACT:
A damper disc having a pair of annular side plates arranged on opposite sides of a flange of a spline hub connected to an output shaft. A torsion spring connected to the side plates and the hub flange and arranged in holes provided on the side plates and the hub flange. A pair of annular side plates having inner peripheral parts are connected by stud pin against the opposite surfaces of the hub flange. The stud pin are passed through a notch of the hub flange with a clearance provided therebetween with an angle larger than a first-stage twist angle and, at the same time, through notches of the side plates, with a clearance provided therebetween with an angle larger than a second-stage twist angle. A stop pin connects the outer peripheral parts of the side plates and is passed through a notch of the hub flange with a clearance provided therebetween corresponding to a maximum twist angle. A friction material, having a friction washer through which the stud pin passes, are disposed between subplates and the side plates. An engage part engaging with the torsion spring is formed on the friction washer. Clearance between the friction washer and the stud pin is eliminated by means of a twist caused by the torsion spring.
