A washing machine includes a bearing housing which is installed on a bottom surface of an outer tub, a clutch stopper which is installed on a bottom surface of the bearing housing, and a driving motor which includes a stator and a rotor which are coupled to a lower side of the clutch stopper, in which the clutch stopper includes a base portion which is disposed on the bottom surface of the bearing housing, and a fastening boss which extends from the base portion to the lower side by a predetermined length and is fastened to stator by a fastening member.

Disclosed herein is a washing machine including an inner tub assembly for accommodating laundry, a pulsator rotatably provided to an inner lower portion of the inner tub assembly, a blade installed at a lower portion of the pulsator to be rotatable independently from the pulsator, the blade being configured to pump wash water to raise the wash water to an upper end of the inner tub assembly, a drive motor for providing rotational power to the pulsator and the blade, and a power transmission unit for transmitting power of the drive motor to the pulsator and the blade, respectively. The power transmission unit transmits power such that a direction of rotation of the pulsator is opposite to a direction of rotation of the blade.
