An alternator damper pulley for a vehicle is disclosed. The alternator damper pulley for a vehicle comprises: a pulley body connected to an engine to receive a rotational force; a shaft connection unit provided to enable a rotary shaft of an alternator to be inserted and coupled into the pulley body; a torsion spring mounted on the outer circumferential surface of the shaft connection unit to reduce a change amount of the rotational force transmitted from the pulley body; a clutch interposed between the torsion spring and the pulley body to control the shaft connection unit and the pulley body; and a friction damper installed to apply a friction damping force to the shaft connection unit. Therefore, the present invention is capable of effectively reducing the change amount of the rotational force transmitted from the engine to the alternator. |
