To provide a washing machine capable of preventing drying irregularities due to lack of loosening and wrinkling due to too much agitation or the like by appropriately determining the execution time of a blade rotating operation when executing drying by the repetition of a tub rotating operation and the blade rotating operation.

The washing machine includes operation control means for acquiring the duty ratio of PWM signals during rotary drive every time of inverting the rotating direction of an agitating body in an agitating rotating operation and controlling a drive control means so as to repeat an inverting operation until the duty ratio becomes a prescribed value or is settled in a prescribed range.
