Abstract

The invention relates to a rotational vibration damper for a crankshaft of a piston engine. The rotational vibration damper comprises a hub which defines an axis of rotation, and a mass member which, via at least one spring element, is coupled to a hub and is able to rotationally vibrate freely relative to the hub. The mass member is annular in shape and is arranged coaxially relative to the hub, wherein the at least one spring element made of steel is provided in the form of a bendable spring.
