PROBLEM TO BE SOLVED: To provide a lockup damper device which is stored in a torque converter, and elastically connects a turbine runner to a piston, and absorbs any torque fluctuation of an engine in a lockup state in which the piston is engaged therewith. SOLUTION: The lockup damper device 10 has a plurality of inner and outer damper springs 8, etc., and 9, etc. The inner damper springs 8, etc. arranged on the inside diameter side and the outer damper springs 9, etc., arranged on the outside diameter side are arrayed in a series state with a third separator 16 interposed therebetween. A piston 4 is engaged with a front cover 6 even in a low engine speed zone in a lockup state. A first stopper is provided so as to cope with a case of a large impact torque applied thereto.
