To mechanically reasonably achieve the high-quality finishing state of laundry with sufficient smoothing of the twining and twisting deeply engraved in laundry after a spin-drying step and with few wrinkles.
Driving of a rotary drum 4, whose rotating axis is horizontal or inclined downward from the horizontal direction from the opened front side to the back side as the bottom, in the drying step is characterized by a forward/reverse arc rotation driving mode which is alternately executed with a forward/reverse continuous rotation driving mode or which is executed between the forward continuous rotation driving mode and the reverse continuous rotation driving mode. In the forward/reverse arc rotation driving mode, the sharp forward arc rotation and the sharp reverse arc rotation at the angle larger than 90 degrees and smaller than 200 degrees are alternately repeated. In the forward/reverse continuous rotation driving mode, the forward continuous rotation and the reverse continuous rotation at the rotating speed indicating the behavior of the laundry brought up by the rotation of the rotary drum 4 to fall from the height where its own weight is heavier are alternately repeated.
