PURPOSE: An inertia changing type damping apparatus for torsion vibration is provided to have regular natural frequency for a torsion vibration damper regardless of change of temperature by offsetting changes of natural frequency with changes of inertia. CONSTITUTION: An inertia changing type damping apparatus of torsion vibration includes a buffing portion(10); a changing portion(14) and a mass portion(16). The buffing portion is composed of buffers as rubber type to support a rotating shaft on a middle portion by inserting the rotating shaft to a through hole(12). The changing portions makes change of inertia with changing a gravity center according to a movement of mass by changing thermal expansion according to change of temperature inside the buffing portion. The mass portion is combined to an outer peripheral surface of the buffing portion and the changing portion. The buffing portion has many through holes(10a) to receive the changing portion. The changing portion comprises thermal expansion materials(14a), a mass body(14b) and a protruded wall(14c). Thereby, natural frequency is maintained regardless of changes of temperature by changing inertia when a spring constant is changed because of change of temperature.
