PURPOSE: A water pump pulley of a vehicle engine is provided to intercept total noise of a vehicle engine and suppress vibration by making a water pump pulley in separated two combination types instead of integrated type for respective tension operations, thereby suppressing generation and transmission of vibration. CONSTITUTION: In a water pump pulley of a vehicle engine, a water pump pulley is formed of combination of a pulley case(11) and a pulley body(12) having respective spring seating grooves(10), wherein the pulley case and the pulley body are coupled with each other apart from each other and include springs(14) for elastically moving inwardly by a predetermined distance, and a retainer(13) is positioned between the pulley case and the pulley body by a predetermined distance for preventing deviation of the pulley case and the pulley body outwardly.
