PURPOSE: To accurately cope with the overlapped case of longitudinal vibration, inclined vibration, high frequency torsional vibration, and the like by forming a rubber ring attached between a boss ring and an inertial ring, in such outline shape as to continuously change in a circumferential direction. CONSTITUTION: A torsional vibration damper has an inertial ring 1 fixed onto a boss ring 3 through a closed rubber ring 2. Adhesive faces 5, 6 of the boss ring 3 and inertial ring 1 in contact with the rubber ring 2 have circumferentially continuous partial zones, and these partial zones are uniformly shifted with large different spaces to a rotary shaft 4. The spaces change circumferentially as well as in the longitudinal direction of the torsional vibration damper, and the outer diameter of an axially extended zone of the rubber ring 2 decreases from an apex 7 toward a point 8 on the radially opposite side. The excellent axial guide of the inertial ring 1 on the boss ring 3 and the relatively flexible support of the inertial ring 1 are therefore obtained to effectively suppress torsional vibration of relatively large torsional amplitude. |
