PROBLEM TO BE SOLVED: To provide a combined damper for simplifying a structure, easily processing and assembling a part, reducing a manufacturing processes and manufacturing cost. SOLUTION: This combined damper has one core material 7 for arranging a plastic part 7h in a central part, and a pair of stiffening members 8 and 8 constituted so that a central part and the other end part 7e of at least the core material 7 are stored inside; and is characterized in that when external force of a low load and very small amplitude is applied to a frame, vibrational energy is converted into frictional energy between an outside surface of the core material 7 and an inside surface of the stiffening members 8 and 8, and when external force of a large load and large amplitude is applied to the frame, after a relative moving distance between the core material 7 and the stiffening members 8 and 8 reaches a predetermined distance, the relative movement of these core material 7 and stiffening members 8 and 8 is restricted by restricting means 8g and 21, and the vibrational energy is absorbed by plastically deforming the plastic part 7h, and a vibrational response to the frame is damped.
