PURPOSE: An alternator damper pulley of a vehicle is provided to secure stable driving state of an alternator, reduce a change in tension of a belt, and reduce noise. CONSTITUTION: An alternator damper pulley of a vehicle comprises an outer ring(1) to which a belt is caught; an inner ring(3) having a coupling hole(7) to connect a shaft of the alternator; and a damper rubber(5) integrally formed between the inner and outer rings along the circumferential direction. Serrations(9) are formed to the inside of the outer ring and to the outside of the inner ring to prevent separation from the damper rubber caused by rotational load. A rigid body connection part(11) is disposed between the inner and outer rings to prevent the center of rotation of the outer and inner rings from being out of line by elasticity.
