CONSTITUTION: A washing machine having an auxiliary pulsator(50) is composed of a washing tub(40) formed with a plurality of mounting units(42) opened inward and installed in a water storage tub; the auxiliary pulsator comprising driving and driven pulleys(52,54) vertically shaft-mounted in both sides of the mounting unit and a friction belt(58) wound around the driving and driven pulleys; and a driving unit for rotating forward and reverse the driving pulley. A plurality of projections(58A) are protruded on the surface of the friction belt.
