ABSTRACT:
A torsional damper device comprises at least two coaxial parts disposed to rotate relative to each other within defined limits of relative angular displacement. Circumferentially acting elastic members are adapted to operate circumferentially between the coaxial parts over part at least of such relative angular displacement. The elastic members includes at least two coil springs spaced circumferentially along a common circumference of the device. Retainers associated with the coil springs, common to all the coil springs, are adapted to retain the coil springs against the action of centrifugal force. The retainers are disposed at least in part radially outside the common circumference.
