Claims

[Claims for Utility Model Registration] ゛ In order to absorb torsional vibration and noise with a wide range of frequencies that occur in the normal rotation range of the engine, each elastic body is provided with inertia through a plurality of elastic bodies with different spring constants. It is a torsional damper whose body is integrally constructed, and noodle-shaped elastic bodies of different diameters are integrally formed on a base plate, and annular inertia bodies are further integrally formed with each of the annular elastic bodies, and the above-mentioned The above-mentioned annular gap corresponding to the partitioning annular gap formed between the inner annular body and the outer annular body among a plurality of annular annular bodies formed of pairs of annular elastic bodies and annular inertial bodies in an integral relationship. A torsional damper characterized in that beads for locking mold pieces are formed on the base plate portion at equal intervals on the circumference, extending over a circular arc of a predetermined length along the curvature of the annular gap.
