PROBLEM TO BE SOLVED: To provide a lock-up damper device which is stored in a torque converter, elastically connects a turbine runner to a front cover, and has high strength of absorbing the torque fluctuation of an engine in a lock-up condition in which a piton engages with the front cover. SOLUTION: A disk 11 is held between an A-plate 9 located on the side of the piston and a B-plate 10 located on the side of a turbine, holding parts 13, 14 are formed on the A-plate 9 and the B-plate 10, respectively, for storing a damper spring 7 fitted to an oblong hole 18 provided passing through the disk 11, an auxiliary damper spring 8 is fitted into a storage space 17 of the holding parts formed on the A-plate 9 and the B-plate 10, and a great oblong hole 19 is provided with a space between an end face 20 of the disc and the front end of the auxiliary damper spring. A window 23 is formed in the outer periphery of the disk 11, and a connection part 22 is arranged at the site of the oblong hole for connecting/fixing the A-plate 9 to the B-plate 10.
