Abstract
A washing machine includes a tub, a drum, a motor, a pulsator, a coupler configured to couple and decouple a driving shaft of the motor and a drying shaft of the drum, and a clutch supporting the coupler and moving in an axial direction. The clutch includes driven protrusions extending in a vertical direction. The washing machine further includes a clutch supporter having a plurality of support surfaces that are spaced apart from each other in a circumferential direction and support lower ends of the driven protrusions located between the support surfaces when the coupler is at a connection position, and guide surfaces that are located above the support surfaces in the circumferential direction and configured to interfere with the upper ends of the driven protrusions based on the clutch moving upwards from the connection position to a disconnection position to thereby rotate the driven protrusions to positions corresponding to the support surfaces.
