PCT No. PCT/AU90/00334 Sec. 371 Date May 1, 1992 Sec. 102(e) Date May 1, 1992 PCT Filed Aug. 6, 1990 PCT Pub. No. WO91/02176 PCT Pub. Date Feb. 21, 1991.An elastomeric damper comprises a hub section configured for connection to a rotational shaft requiring damping in an internal combustion engine, and an inertia ring fitted within the hub section. The hub section includes a central region, an annular radially extending section extending radially outwardly from the central region, and an annular axially extending section extending axially with respect to the radially extending section. The axially extending section includes a radially inwardly directed portion. An annular inertia ring is located inwardly of the axially extending section, and an elastomeric material is located between the outer circumferential surface of the inertia ring and the inner circumferential surface of the axially extending section, the radially inwardly directed portion of the axially extending portion having a length terminating radially inwardly of the outer circumferential surface of the inertia ring, so that the inertia ring is retained between the radially inwardly directed portion and the radially extending section.
