PURPOSE: A damping structure of a clutch disc is provided to absorb a noise resulted from a hit between a spline hub and a hub plate, and a backlash of a transmission, by increasing the pre-damping torque of a clutch. CONSTITUTION: A damping structure of a clutch disc comprises: a hub plate (10) to be mounted in the inner side of a disc plate (26), to form a gear part on the inner surface; a friction washer (24) to press a hub plate through a wave spring (22), which is interposed between the hub plate and the disc plate; a damping plate (40) to be interposed between the friction washer and the hub plate, and to be pressed by the hub plate; a spline hub (6) to be mounted in the inner side of a hub plate (26), to form a gear part on the outer surface; a friction bushing (18) to stick to the spline hub through a friction spring (20) interposed between the spline hub and the disc plate; a damping lever (50) to stick to and to be supported by the inner surface of the friction bushing, to be mounted in the gear part of the hub plate, and to be adjacent to the gear part of the spline hub.
