To decrease the direct application of centrifugal force to a coupling section and to improve durability by setting the coupling section of a side face plate concerning a spinning tub for washing machine provided with the side face plate for which both terminal parts in the shape of rectangular plate are coupled and formed cylindrical and a lifter is formed so as to be protruded inside.

Concerning a drum washing machine for which a fixed tub is hung while internally mounting a drum-shaped spinning tub inside a main body case, the spinning tub is composed of a front panel and a back panel coupled to both the side parts of the cylindrical side face panel of which both the front and rear side parts are opened. Concerning this side face panel 31 of the spinning tub, plural lifters 35 protruded inside while being V-shaped are arranged separately at fixed intervals and when the spinning tub spins, laundry is pulled up and dropped. Besides, the side face panel 31 is produced by bending a rectangular panel cylindrical and coupling both the mutually contacting terminal parts but in this case, a coupling section 36 is placed on the lifters 35 to be bent so as to be protruded inside so that no external force or the like can be directly applied.
