The present invention relates to a clutch disc which comprises: a disc plate for receiving torque from an engine to rotate; a sub-plate for rotating as one body with the disc plate; a hub plate placed in between the disc plate and the sub-plate to have multiple combining grooves on the inner circumference; a main damper spring for conveying the rotation of the disc plate and the sub-plate to the hub plate; a hub inserted into the inner circumference of the hub plate with a free damper spring as a medium to have a combining bump, which is accommodated in the combining grooves to be able to flow and formed on the outer circumference, and to be combined with a transmission input shaft with a spline; and a damping unit placed in between the hub and the hub plate to reduce the impact generated between the hub and the hub plate when moving from a free damping section to a main damping section. Accordingly, the present invention can prevent the generation of vibration and noise by an impact when moving from the main damping section to the free damping section. |
