いる。2. Description of the Related Art In a conventional washing machine, as shown in FIGS. 12 and 13, a washing / dewatering tub (hereinafter referred to as an inner tub) 1 made of stainless steel is installed in a washing machine case.
(Reference: Japanese Patent Laid-Open No. 4-197889) The inner tab 1 is composed of a ring 1a for forming an upper part and for mounting the fluid balance 4, a cylindrical main body 1b for forming a body, and a bottom plate 1c for forming a lower part. There is. A washing wing 3 is rotatably installed on the bottom plate 1c.

との摩擦効果が下部よりも弱いからである。This is because in the lower part of the inner tub 1, the direct friction between the laundry and the washing wing 3, the friction between the laundry due to the rotating water flow generated by the left and right rotation of the washing wing 3, and the inner circumference of the inner tub 1. There is friction between the embossing convex portion 2 formed inward on the surface and the laundry, but there is no direct friction by the washing blade 3 at the upper part of the inner tub 1, and the washing blade 3
This is because the rotating water flow generated by is weaker than the lower part, and thus the friction between the laundry due to the rotating water flow and the friction effect between the embossing convex portion 2 and the laundry are weaker than the lower part.
