A clutch disk for an automobile is provided to effectively prevent hitting noise generation of a transmission by forming a damper spring used for a clutch disk in a plate spring type so as to having lower spring constant and a large damping angle. A clutch disk for an automobile comprises a facing(110), a hub(120), a first damper spring(130), a second damper spring(140), a first plate cover(150) and a second plate cover(160). The facing is provided with a hole(113) in the middle, and forms a first mounting surface(111) and a second mounting surface in both side surfaces. The hub is provided with a first locking ridge(121) and a second locking ridge(122) in outer side circumference. The first damper spring has one end fixed to the first mounting surface and the other end fixed to the first locking ridge of the hub. The second damper spring has one end fixed to the second mounting surface and the other end fixed to the second locking ridge of the hub. The first plate cover is fixed to the first mounting surface so that the first damper spring is separated from the first mounting surface, and provided with a first stopper(152) so as to control a rotation angle of the first locking ridge formed in the hub. The second plate cover is fixed to the second mounting surface so that the second damper spring is separated from the second mounting surface, and provided with a second stopper(162) so as to control the rotation angle of the second locking ridge formed in the hub.
