うに配置された複数個の遊星歯車19とを備えてなる。The speed reduction device 8 is constructed as shown in FIG. 1 in detail. 9 is a lower case 10 and an upper case 11
This case is screwed to the outer bottom of the washing tub 4. 12 is a lower case 10 which is one side of the case 9;
The input shaft is inserted into and supported by the cylindrical portion 10a, a pulley 13 constituting a part of the belt transmission mechanism 7 is attached to the lower end, and the upper end protrudes into the case 9. Reference numeral 14 denotes an output shaft that is inserted through and supported by the cylindrical portion 11a of the upper case 11, which is the other side of the case 9. The agitator 5 is attached to the upper end in the washing tub 4, and the lower end is connected to the input shaft 12. They protrude into the case 9 so as to face each other. Reference numeral 15 denotes a gear mechanism disposed within the case 9, which includes an annular internal gear 16 supported on the inner bottom surface of the lower case 10, and a serration joint mechanism 17 fitted and connected to the upper end of the input shaft 12. The sun gear 18 is disposed at the center of the internal gear 16, and a plurality of planetary gears 19 are disposed so as to mesh with both the internal gear 16 and the sun gear 18.

る。In the above configuration, when the motor 6 rotates, the rotation is transmitted to the input shaft 12 of the reduction gear device 8 via the belt transmission mechanism 7.
The sun gear 18 rotates. Then, each planetary gear 19 makes a planetary motion around the sun gear 19 while rotating, and the upper and lower brackets 20 and 2 rotate integrally with this planetary motion. The rotation of the upper bracket 20 causes the output shaft 14 to rotate, causing the agitator 5 to rotate at a low speed.

減できた。When the agitator 5 is driven (during washing), noise is generated from the gear mechanism 15, but in the above configuration, the gear mechanism 15 is covered twice by the cup 24 and the case 9. , it is possible to suppress as much as possible the sound generated from the gear mechanism 15 from leaking outside the case 9,
Noise can be reduced. Incidentally, according to the present embodiment in which the cup 24 is provided, the sound leaking from the case 9 can be reduced by 2 [dB] compared to the conventional configuration in which the power valve is not provided.
尚、カップ24の例えばケース9との間に別途吸音材を
設けることにより、騒音の一層の低減化を図ることがで
きる。Note that by separately providing a sound absorbing material between the cup 24 and the case 9, for example, the noise can be further reduced.
