Abstract
A damper pulley assembly for a vehicle is provided and includes a crank shaft of an engine of the vehicle, a hub that is coupled to the crank shaft and configured to be rotated, a pulley that is coupled to an exterior surface of the hub and configured to be integrally rotated with the hub and an oil seal that is disposed between the hub and an interior of a cylinder block configured to prevent engine oil leakage in the cylinder block. The hub has an abrasion prevention component formed on an exterior circumference surface on which the oil seal is disposed, and the abrasion prevention component prevents separation of the oil seal. Thus, a friction coefficient of a portion where a contact with the oil seal is concentrated is reduced and abrasion of a shaft is reduced by applying an anti-abrasion coating to improve hardness.
