A pedal force simulator device includes: a pressure piston actuatable by a brake pedal and axially moveably mounted in a housing; and at least two disk spring stacks connected in series, each disk spring stack having at least two disk springs, at least two of the disk spring stacks having different spring constants, and the disk spring stacks being situated in the housing between an end face of the pressure piston and an axial stop of the housing. At least one of the disk spring stacks includes an axial receiving recess, in which a spring element, which can be elastically deformed by the pressure piston, is situated, one end of the spring element being supported on the pressure piston and the other end being supported on one of the disk spring stacks.
