formed on the plate member 253 and the rest of it is formed by an inward groove 231b 34 on the front panel 231 most of the inner race 251a is formed by an inward groove 231a 34 formed on the front panel and the rest of it is formed by an outward groove 253a 34 on the plate member forming the races 251a 251b in this manner provides for an easier injection molding process the washing process carried out by the drum washing machine of fig2 will now be described when the drum washing machine starts to operate the electric motor 40 operates according to a prescribed program so that the spin basket 30 rotates the cleaning of the clothes contained therein is carried out by the use of the suds generated by the rotation of the spin basket 30 and further created by the action of the lifters 33b formed on the side panel 33 of the spin basket 30 the laundry and water are agitated by the lifters 33b and the side panel 33 the water is then removed from the laundry by centrifugal force as the spin basket 30 rotates at high speeds and drains into the tub 20 through the holes 33a formed in the side panel 33 the vibrations that are created by the uneven distribution of laundry in the spin basket 30 can be reduced by the following procedure the laundry is located on the bottom of the spin basket 30 in the initial stage of the hydro extracting process as the spin basket 30 rotates at high speeds the balls 52a and 52b are moved to the opposite side of the imbalance along the corresponding races 51a and 51b by the centrifugal force created.
