    • PURPOSE: An inertia changing type damping apparatus of torsion vibration is provided to maintain natural frequency by offsetting changes of a spring constant of a buffing portion due to change of temperature with change of inertia due to changes of a diameter of a changing portion. 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 portion is combined to an outer peripheral portion of the buffing portion. The changing portion changes a diameter according to change of temperature by changing thermal expansion to change inertia. The mass portion is inserted to the changing portion. The changing portion comprises first and second metal plates(14a,14b). The first metal plate inside the changing portion has low thermal expansion rate and the second metal plate outside the changing portion has high thermal expansion rate relatively. First and second metal plates are arranged around the buffing portion radially. Therein, the changing portion changes a diameter by changing curvature of pieces like a bimetal according to change of temperature. Therefore, normal damping function is operated.
