お、１１は糸くずフィルターである。As shown in the figure, a washing and dehydrating tub 1 has a stirring blade 2 rotatably arranged on the bottom surface and a mounting flange 3 mounted on the back surface of the bottom surface. A water receiving tank 4 is provided outside the washing / dehydrating tank 1. A drive motor 5 for driving the washing / dehydrating tank 1 and the stirring blade 2 is attached to the back surface of the water receiving tank 4. Further, the water receiving tank 4 is supported on the outer frame 6 by a suspension 7 so as to be vibration-proof. A fluid balancer 8 containing a liquid is fixed to the upper part of the washing / dehydrating tub 1. A substantially U-shaped water passage 9 is fitted to the side surface of the washing / dehydrating tub 1 to form a circulation water passage, and the water on the back surface of the stirring blade 2 is washed with the water passage 9 by the rotation of the stirring blade 2. After passing through the circulating water passage formed by the water tank 1, it reaches the fluid balancer 8 and is discharged from the opening 10 of the water passage 9 into the washing / dehydrating tank 1. In addition, 11 is a lint filter.

を有していた。In the conventional washing and dehydrating tub as described above, the thermal expansion coefficient of the resin and the metal is greatly different (the thermal expansion coefficient of the metal is 8 × 10) under the present circumstances in which the stirring blade 2 is formed of the resin. -6 mm / ℃, resin is 100 × 10 -6
9 mm / ° C.), therefore, as shown in FIG. 9, due to a change in outside air temperature and a dimensional difference due to a difference in thermal expansion coefficient between the stirring blade 2 when hot water is used during washing and the periphery of the stirring blade 2 of the washing / dehydrating tank 1.
