Abstract
A washing machine that has at least one balancer that increases durability by reinforcing the strength of the balancer and is installed on a rotating tub in a rapid and convenient way. The balancer includes first and second housings that have an annular shape and are fused to form a closed internal space, and the first housing including at least one support for reinforcing the strength of the balancer. A spin tub includes an annular recess corresponding to the balancer so as to be coupled with the balancer. The support protrudes from the first housing and comes into contact with a wall of the recess and guides the balancer to be maintained in the recess in place. The supports are integrally molded to the first housing at predetermined intervals along at least a first wall of the first housing.
