A damper pulley is provided to reduce a manufacturing cost by removing an additional coupling bolt based on combination of an acoustic absorbent with a pulley through rotation. A damper pulley includes a pulley(50), an acoustic absorbent(52), an acoustic absorbent cover(54), and a coupling unit(60). The pulley is coupled to a crank shaft. The acoustic absorbent is coupled to a front portion of the pulley. The acoustic absorbent cover coupled to the pulley covers the acoustic absorbent. The coupling unit fixes the acoustic absorbent cover and the pulley to the crank shaft. The acoustic absorbent cover is coupled to the pulley by rotation. |
