Abstract: PURPOSE: To obtain a reliable and inexpensive structure of a balance adjusting balancer which eliminates vibration caused by the uneven distribution of laundry in spin-drying. CONSTITUTION: The balancer 20 is attached to the rear part of a rear board 6d of a drum 6, which has a plurality of water storing chambers that are respectively divided by radial partitioning walls in the circumference of a main shaft 7 and respectively provided with an opening for a water flow at an inner peripheral side. A nozzle 30 for pouring water into each storing chamber is arranged in the rear side surface part of an outer tub 3. After the whole water storing chambers are filled with water injected from the nozzle 30, a part of water is discharged by the temporary reduction of the rotary speed of the drum 6 in response to an eccentric load by the uneven distribution of the laundry so that balance is adjusted. The balancer 20 is made of a member obtained by joining two members by thermal melt-sticking, which are divided on a plane being orthogonally crossed with an axis. A double wall structure is adopted in the partitioning walls to be a joining part and an outer peripheral wall so as to prevent the fall of an abutment piece in the case of thermal melt-sticking and also to prevent a break owing to a force which is received from the stored water in the case of centrifugal dehydration.
