A clutch disk assembly including a double friction spring is provided to extend load maintaining period against the abrasion of a clutch disk damper. A clutch disk assembly including a double friction spring is composed of a clutch contacting part(270) receiving the torque by the friction contact, a hub plate(210) in which a through-hole of the axial direction is formed in the center, a sub-plate(235) and a disk plate(230) in which an axial through-hole is each formed in the center, a hub(200) combined with the and sub-plate and a disk plate, a first friction bushing(220) installed between the hub and the sub-plate, a second friction bushing(223) installed between the hub and the sub-plate, a first friction spring(225) installed between the first friction bushing and the sub-plate, and a second friction spring(227) installed between the second friction bushing and the disk plate.
