Claims

[Scope of utility model registration request]

a main shaft that is driven by a motor via a pulley; an outer cylinder that is fitted onto the main shaft and that rotates the main shaft intermittently by switching a spring clutch; and a main shaft that is provided on the outer periphery of the main shaft. a gear case that covers the reduction gear group and rotates integrally with the outer cylinder and rotates the washing tub by the rotational force of the gear case, and rotation of the entire reduction gear group. The rotational drive mechanism of an electric washing machine includes a pulsator shaft that rotates a pulsator by the rotational force transmitted thereto, wherein the gear case includes a large-diameter cylindrical portion surrounding the outer periphery of the reduction gear group, and a large-diameter cylindrical portion surrounding the outer periphery of the reduction gear group; Consisting of a curved part formed by extending the upper end circumferential part of the cylindrical part so that the diameter gradually becomes smaller on the upper side, and a small diameter cylindrical part formed by extending the upper end circumferential part of the curved part upward. A rotational drive mechanism for an electric washing machine, characterized in that an annular groove centered on the axis is formed along the circumference on the outer peripheral surface of the curved part.
