PURPOSE: A structure a free damper of a clutch disc is provided to absorb shocks between a clutch hub and a clutch plate, which are generated at the moment power is transmitted, with the free damper and a damping member and accordingly to prevent shock and vibration. CONSTITUTION: A structure for a free damper(54) of a clutch disc is composed of a hub flange(52) formed in a saw tooth shape along the circumference of a clutch hub(51), a tooth-shaped plate flange(53) fixed to the clutch disc and formed to be slightly larger than the hub flange with having a stopper(53') at an edge to cut off the rotation of the hub flange, the free damper absorbing shocks generated in a relative rotation, an end of the free damper fixed to the hub flange and other end fixed to the plate flange, and an auxiliary damper unit(55) installed to the stopper of the plate flange to absorb shock generated in colliding with the hub flange.
