Claims

[Scope of Claim for Utility Model Registration] (1) A main shaft whose upper end is formed into a gear part A, and a gear part A of the main shaft.
A planetary gear group whose inner surfaces mesh with each other to reduce the rotation of the main shaft, and a gear case whose inner circumferential surface is formed into a gear part B and which meshes with the outside of the planetary gear group to transmit the rotation to the washing tub. In this rotary drive mechanism for an electric washing machine, the gear tooth rising surface at the lower end of the gear section A is formed into a tapered surface, and the gear tooth rising surface at the upper end of the gear section B is formed into a tapered surface. An electric washing machine characterized in that the upper and lower ends of the teeth of each small-diameter gear of the planetary gear group are chamfered into tapered surfaces corresponding to the tapered surfaces of the gear portions A and B, respectively. rotational drive mechanism. (2) The gap between the tapered surface of the upper end of gear part B and the tapered surface of the upper end of each small diameter gear of the planetary gear group is 10
The rotational drive mechanism for an electric washing machine according to claim (1), wherein the rotational drive mechanism is set to be less than mm.
