駆動する。Next, the operation of the above configuration will be explained. FIG. 4 shows the state during washing, in which the lever 30 restrains the rotation of the clutch case 28 by the clutch-side engaging part 30a, and restrains the rotation of the brake band 29 by the brake-side engaging part 30b. . Therefore, as is well known, the clutch spring 27 cannot be tightened and the rotation of the motor 7 is not transmitted to the hollow shaft portion 18, and the main body case 15 and, in turn, the rotating tank 4 are prevented from being braked. ing. During washing, the motor 7 rotates in forward and reverse directions in this state, and the rotation is transmitted from the driven pulley 24 to the input shaft 21 of the reduction gear 8, causing the sun gear 33 to rotate. Then, the sun gear 3
3 and the internal gear 32, the planetary gear 34 meshes with both the internal gear 32 and the internal gear 32, and rotates on its own axis while making a planetary motion around the sun gear 33. Along with this planetary motion, both the upper and lower brackets 36 and 37 rotate integrally. The rotation of both brackets 36 and 37 causes the output shaft 16 to rotate, thereby driving the pulsator 5 to rotate at a low speed.

In order to release the restraint of the clutch case 28 and the brake band 29 by the clutch case 28 and the brake band 29, as is well known, when the clutch spring 27 is freely tightened, the brake of the main body case 15 and thus the rotating tank 4 is released. During dewatering, the motor 7 rotates in one direction in this state, and the rotation is transmitted from the driven pulley 24 not only to the input shaft 21 but also to the hollow shaft portion 18 via the clutch spring 27. 5 rotate at high speed as one unit.

不要ならしめ得る。According to the configuration of 1, the internal gear 32 is integrally formed with the main body case 15.
This allows the internal gear and the case to be shared in common, compared to conventional systems in which the internal gear and the case are configured separately.
5 can be reduced in radial direction, and as a result, the entire speed reduction device 8 can be downsized. Here, the reduction ratio S of the reduction gear 8 is expressed as S-1/(1+A/B), where A is the number of teeth of the internal gear 32 and B is the number of teeth of the sun gear mechanism 33. From this, when the number of teeth B of the sun gear 33 is constant, the reduction ratio S increases as the number A of teeth of the internal gear 32 increases. Therefore, according to this embodiment, if the reduction ratio is the same as the conventional one, the number of teeth of the internal gear 32 can be the same as the conventional one.
As mentioned above, the outer diameter of the main body case 15 can be made smaller, and the positive amount can be reduced accordingly. Conversely, when the outer diameter of the main body case 15 is made the same as before, the diameter of the internal gear 32 can be made larger. Since the number of teeth can be increased accordingly, the reduction ratio can be increased without increasing the size of the main body case 15. In addition, by integrating the internal gear 32 into the main body case 15, the number of parts can be reduced accordingly, and since there is essentially no need to incorporate the internal gear 32 into the main body case 15, the main body case 15 can be integrated. Case 15 and internal gear 32
Since there is no misalignment between the
Furthermore, it is possible to reduce the number of parts such as screws for assembling the internal gear 32, and it is also possible to eliminate the need for machining to attach the screws and the like.

The material is not limited to this, and may be made of plastic.Although in the above embodiment the deceleration device is applied to a dehydrating/washing machine, it may also be applied to a deceleration device that drives the pulsator in a two-tub washing machine. Furthermore, it can be widely applied not only to the speed reduction device of a washing machine but also to cases where it is desired to increase the speed reduction ratio while avoiding an increase in size.

It is possible to increase the reduction ratio while avoiding this, and it is also possible to reduce the number of parts. Moreover, since there is essentially no need to assemble the internal gear into the main body case, it is possible to improve assembly accuracy and reduce manufacturing costs, which brings about various excellent effects.
