Abstract
A ball balancer for a washing machine having a rotary tub is provided. The ball balancer comprises an annular casing installed coaxially atop a cylindrical body of the rotary tub and having a radial inner wall and a radial outer wall to form an annular chamber therebetween. Balancing balls and viscous fluid are movably contained in the chamber. An annular reinforcing member is arranged coaxially with the outer wall and is disposed radially inside or outside of that outer wall for reinforcing the outer wall against radially outward forces. The reinforcing member may comprise a cylindrical band attached to the outer wall, or it may be defined by an upper portion of the cylindrical tub body.
