Damper (400) for a washing machine including an upper buffering member (420) fitted to an inside of an upper portion of a washing machine housing, an elastic member (440) under the lower buffering member (430) for elastic supporting of the lower buffering member (430), and a damper bar (410) for passing through, and connecting the upper buffering member (420), the lower buffering member (430), and the elastic member (440) in succession, for damping vibration and impact, wherein the upper buffering member (420) has a through hole (431) for passing the damper bar (410) therethrough with an upper diameter equal to, or smaller than a diameter of the damper bar (410), a lower diameter greater than a diameter of the damper bar (410), and the lower buffering member (430) has an extension (434) projected upward from an upper surface, a plurality of reinforcing ribs in an upper portion of the extension, sloped guide ribs (436) extended downward from a bottom thereof for preventing the lower buffering member (430) from coming out of a top of the elastic member (440), and a hole (431) for passing the damper bar (410) therethrough, with an etched rugged inside surface for containing grease. |
