  • Patent number: 10995444
    Abstract: The washing machine of the present disclosure includes an improved pulley for reducing the noise generated in the pulley. When the shaft is inserted into the shaft insertion hole, at least a part of the shaft is closely contacted with the shaft insertion hole to minimize the tolerance between the shaft and the shaft insertion hole, and the rotation shaft of the pulley and the center axis of the shafts may be made to coincide with each other, so that the noise generated by the rotation of the pulley can be effectively reduced. In addition, the spoke of the pulley includes the curved portion, thereby reducing the friction with the air and effectively reducing noise due to friction with air.
