転自在に支承されている。(Structure of a conventional example and its problems) A conventional example of a one-tub type dehydrating washing machine and its problems will be explained with reference to FIGS. 1 to 3. In the figure, 1 is a lower bearing case, and a lower bearing 2 is press-fitted into the lower part of this lower bearing case 1, and a lower dehydration shaft 3 is press-fitted into the inner ring of the lower bearing 2.
A washing shaft (not shown) is attached to the driven pulley 5 inside the drive shaft 4.
It is fixed with. Further, the lower end of the one-way clutch spring 6 is locked to one end of the clutch boss 7, and when the clutch claw 8 is locked to the outer gear part of the clutch boss 7, the lower dewatering shaft 3 and the clutch spring 6 are connected to the drive shaft. 4 rotates left and right, the rotation is not transmitted to the lower dehydrating shaft 3, and only the upper washing shaft 14 supported concentrically with the lower dehydrating shaft 3 rotates. A reduction gear is housed within the brake drum 15, and power is transmitted from the reduction gear to an upper washing shaft 14' that is housed concentrically with the upper dewatering shaft 3', thereby rotating the O/resator 11. Further, an upper bearing 17 is press-fitted into an upper bearing case 1' fixed to the lower bearing case 1, and an upper dewatering shaft 3' is rotatably supported on the inner ring of the bearing.

水槽９を回転させる。During dehydration operation, by separating the clutch claw 8 from the clutch disk 7, only one direction rotation of the driven pulley 5 is transmitted between the drive shaft 4 and the lower dehydration shaft 3 by the clutch spring 6.
The upper dewatering R1113' is rotated, and the receiving metal fitting 19 fixed to the upper dehydrating shaft 3' and the washing/dehydrating tank 9 fixed to the receiving metal fitting 19 are rotated.

びナラＩ・２１で固着することにより行なわれている。A stepped portion 23 is formed on the two-part dehydrating shaft 3', and a comb member 22 is attached to the stepped portion 23.
This is done by fixing the retaining plate 20 and the oak I.21 through the receiving plate 22 coated with a.

せず軸受ン〜ル１８の水密性を更に向上させている。As a retention structure for the seal portion of this part, a cylindrical rib 19a is formed in the center of the receiving metal fitting 19, and this cylindrical rib 19'a and the tip of the bearing sole 18 overlap to form a cylindrical shape. An air retaining portion is formed within the shaped rib 19a. As a result, even if the washing water reaches the rated water level in the outer tub during washing operation, the air retention within the cylindrical rib 19a prevents water from entering the tip of the award seal 18 and the bearing. - further improves the watertightness of 18.

転する場合強度的に不安定になり脱水時の振動の増大や
受金具１９の固着部の耐久性能等に問題を有していた。However, conventionally, this method has had the following structural problems. That is, since the surface of the receiving plate 22 is coated with an elastic member such as rubber, the elastic member is sandwiched between the stepped portion 23 of the upper dehydration shaft 3' and the contact surface between the receiving metal fitting 19 and the receiving plate 22. Therefore, when the washing/dehydration tank rotates at high speed during dehydration operation, the strength becomes unstable, resulting in problems such as increased vibration during dehydration and durability of the fixed portion of the receiving fitting 19.
又、段部２３とゴム部材２２ａの当接によりゴム部材が
切れて空気留め部のシール性が悪くなるという欠点も有
していた。Further, there is also a drawback that the rubber member breaks due to the abutment between the stepped portion 23 and the rubber member 22a, resulting in poor sealing performance of the air retaining portion.

The ribs 19a- are brought into contact with the inner circumferential surfaces of the ribs 19a- to form a seal. As a result, the air retaining part can be made complete, and there is no need to coat the receiving plate 22 with an elastic member as in the conventional case. The receiving fitting 19 can be fixed to the dewatering shaft 3' by inserting it between the two.
