To provide a washing machine capable of reducing washing unevenness and cloth damage, and capable of achieving improvement in washing performance.SOLUTION: A pulsator 26 includes: a base part 100; a movable blade part 200 which protrudes from an arrangement surface 100a of the base part 100; a variable mechanism part 300 for varying the protrusion height of the movable blade part 200 according to the rotation direction of the pulsator 26; a drive motor; and a control unit. The variable mechanism part 300 includes: a rotary part rotatable with respect to the base part 100; and a movement cam for moving the movable blade part 200 to the protrusion position according to the rotation of the rotary part. The base part 100 includes a first stopper rib to which the rotary part comes into contact when the movable blade part 200 moves to the protrusion position. In the control unit, with respect to the drive motor, the start-up section up to the target rotational frequency includes a first section and a second section following the first section. In the first section, rotation start-up control is performed so as to achieve constant velocity, the rotary part comes into contact with the first stopper rib in the first section, and the rotary part and the base part 100 rotate integrally.SELECTED DRAWING: Figure 3 【課題】洗浄むらや布傷みを低減でき、洗浄性能の向上を図ることができる洗濯機を提供する。【解決手段】パルセータ２６は、ベース部１００と、ベース部１００の配置面１００ａから突出する可動羽根部２００と、パルセータ２６の回転方向に応じて可動羽根部２００の突出高さを可変させる可変機構部３００と、駆動モータと、制御部とを含む。可変機構部３００は、ベース部１００に対して回転可能な回転部と、回転部の回転に伴って可動羽根部２００を突出位置へ移動させる移動カムとを含み、ベース部１００は、可動羽根部２００が突出位置へ移動したときに回転部が当たる第１ストッパリブを含む。制御部は、駆動モータに対して、目標回転数までの立ち上り区間が第１区間と当該第１区間に続く第２区間とを含み、第１区間では等速度となるような回転立ち上げ制御を行い、第１区間で回転部が第１ストッパリブに当たり、回転部がベース２００と一体となって回転する。【選択図】図３
