Abstract: A washing machine includes a dewatering shaft for rotating a washing tub, a drive shaft for rotating a pulsator in the washing tub, a coupler configured to move along the dewatering shaft to couple or decouple the drive shaft and the dewatering shaft, a solenoid configured to move the coupler, and a coupler guide configured to be rotated by contact with the coupler or to maintain the coupler in the second position. The coupler includes locking protrusions configured to lock onto an upper side of the coupler guide. The coupler guide includes first guide projections disposed on an outer perimeter of the coupler guide and configured to contact one of the locking protrusions to rotate the coupler guide, and second guide projections disposed opposite to the first guide projections and configured to contact another of the locking protrusions to rotate the coupler guide.
