PURPOSE:To prevent the bonded part of a torsion rubber from being eroded and damaged by sand, by extending the inner peripheral surface of the torsion rubber over the inner peripheral surface of an inertia ring and as well in the direction toward the center of a damper plate from the inner peripheral surface of the inertia ring. CONSTITUTION:A torsion rubber 3 having both outer surfaces to which an inertia ring 2 is bonded, is bonded to both surfaces of the outer peripheral edge of a circular damper plate 1 fitted onto the rotary shaft of a crankshaft or the like. Further, the inner peripheral surface of the torsion rubber 3 is extended over the inner peripheral surface 2a of the inertia ring 2 and as well in the direction toward the center of the damper plate 1 from the inner peripheral surface 2a of the inertia ring 2. That is, there are formed an extending part 4 which covers the entire inner peripheral surface 2a of the inertia ring 2 and an extending part 7 directing to the center of the damper plate 1. |
