軸３′が回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; a lower bearing 2 is press-fitted into the lower part of the lower bearing case 1; a lower dehydration shaft 3 is press-fitted into the inner ring of the lower bearing 2; and a washing shaft (not shown) is driven inside the drive shaft 4. It is fixed together with the pulley 5. Also, the lower end of the one-way clutch spring 6 is locked to one end of the clutch boss 7, and when the clutch pawl 8 is locked to the outer gear part of the clutch boss 7, the lower dewatering shaft 3 and the clutch spring 6
The structure is such that even when the drive shaft 4 rotates left and right, the rotation is not transmitted to the lower dehydration shaft 3, and only the upper washing shaft 14, which is supported concentrically on the lower dehydration 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 pulsator 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.
外槽１０は外箱１２に懸垂支持されており底部

１９に固着された洗濯兼脱水槽９を回転させる。 During dehydration operation, use clutch claw 8 to clutch boss 7.
By separating the driven pulley 5 further, 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, and the upper dehydration shaft 3' is rotated.
The receiving fitting 19 fixed to the upper dehydrating shaft 3' and the washing/dehydrating tub 9 fixed to the receiving fitting 19 are rotated.
電動機１３は制御ダイマーにより洗濯時は反転
をし、脱水時は一方向回転のみをＶベルト１６に
て従動プーリー５に動力伝達をする。 The electric motor 13 is reversed during washing by a control dimer, and only rotates in one direction during dehydration, and power is transmitted to the driven pulley 5 through the V-belt 16.

り行なわれている。 The receiving fitting 19 is attached to the upper dewatering shaft by forming a stepped portion 23 on the upper dehydrating shaft 3', and fixing it with the holding plate 20 and nut 21 via the receiving plate 22 coated with a rubber member 22a on the stepped portion 23. It is done by doing.

軸受シール１８の先端部には水は浸入せず軸受シ
ール１８の水密性を更に向上させている。 As a protection structure for this part of the seal, a cylindrical rib 19a is formed in the center of the receiving fitting 19, and this cylindrical rib 19a and the bearing seal 1
An air retaining portion is formed within the cylindrical rib 19a so as to overlap with the tip portion of the cylindrical 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 bearing seal 18, making the bearing seal 18 watertight. It further improves sex.
しかしながらこの方式では従来下記の様な構造

た。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。 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 clamped to 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. 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.

A sealing annular elastic member having a lip portion with a circular cross section and connecting both lip portions with a thin wall is provided, with the inner lip portion being attached to the outer circumferential surface of the dehydration shaft and the outer circumferential lip portion being attached to the inner circumferential surface of the cylindrical rib. The feature is that they are arranged so that they are in contact with each other, and with this configuration, the air retaining part can be made complete, and at the same time, the fixation of the receiving fitting to the dewatering shaft can be made more secure. It becomes possible.

In the figure, reference numeral 24 denotes an annular elastic member in which thin-walled lip parts 24a and 24b, each having a circular cross section, are connected to the inner and outer peripheral parts.As shown in the figure, the inner lip part 24a is connected to the dehydration shaft 3', The lip portions 24b are brought into contact with the inner peripheral surfaces of the cylindrical ribs 19a to form a seal. This makes it possible to complete the air retainer, eliminating the need to coat the receiving plate 22 with an elastic member as in the past, and as shown in the figure, the metal receiving plate 22 can be directly connected to the stepped portion 23 of the dehydration shaft. Insert between the boss parts and receive bracket 1

せることができる。(Effects of the Invention) As explained above, according to the present invention, the stepped portion of the upper dehydration shaft and the metal part of the receiving plate are in contact with each other, and the lower surface of the receiving bracket is in contact with the metal surface of the receiving plate. This makes it possible to securely attach the receiving bracket to the dewatering shaft, thereby improving durability and reducing vibration during dewatering. This makes it possible to ensure the sealing performance of the air retainer, thereby further improving the watertightness of the bearing seal.
また、内外のリツプ部形状を断面が円形とした

等で精度を出す必要もなく、完全なシール性能を
安価な構成部品で得ることができる。 In addition, since the inner and outer lip parts have a circular cross section, there is no need to use special machining to improve the surface roughness of the mating member, and perfect sealing performance can be obtained with inexpensive components. .
さらに、内外リツプ部を薄肉で連結しているの
で、外側リツプ部の変形による干渉が内側リツプ
部に働かないため、完全な内外シールができる。 Furthermore, since the inner and outer lip portions are connected with a thin wall, interference due to deformation of the outer lip portion does not act on the inner lip portion, so a perfect seal can be achieved.
