Abstract: A crank damper pulley structure of an internal combustion engine of a car in which the hub of a pulley, which is removably fixed to the tip of the engine crank shaft and transmits power to auxiliary machinery, such as an alternator, has therearound a damper mass and a damper rubber comprising a torsional damper. The hub has a cavity therein which opens to one end of the hub. A damper support is fixed in the cavity and a ring-like damper and a ring-like damper mass are superposed axially with the rubber being fixed to the mass and the support in order to constitute a ring-like dynamic damper disposed in the cavity which copes with bending vibration of the crank shaft.
