A damper clutch of a torque converter of the present invention can reduce generation of abnormal vibration and a booming noise in low speed and also, can lower engaging torque and enhance fuel efficiency with multiple elastic damping force. A damper clutch of a torque converter includes a plurality of damper spring that are disposed along radial direction and a plurality of spring supporter that are disposed between the damper springs and pressurizes the damper springs along radial direction when power is delivered from a piston to a turbine, wherein each two spring supporters, putting opposite, form a group and each group has different length for supplying multiple elastic damping force.
