PROBLEM TO BE SOLVED: To provide a lock-up damper device housed in a torque converter in a structure of a two-divided power transmission passage. SOLUTION: In the lock-up damper device, a plurality of damper springs 8a, 8a..., 8b, 8b... are arranged at an outer circumference side and an inner circumference side of which the radii are different, an auxiliary damper spring 10 that works when the relative twist angle between an outer plate 14 that is an input side member and a center disc 15 that is an output side member exceeds a predetermined range is attached to the outer circumference of the outer plate 14, a disc 38 is fixed at the outer circumference of a turbine runner 2, and a spring presser 39 compressed by being brought contact with the auxiliary damper spring 10 is protruded to the disc outer circumference.
