Abstract
A refrigerator includes a rack gear assembly on a lower surface of a drawer, and the rack gear assembly has a first rack member and a second rack member moved forward sequentially while moving forward such that an opening distance of the drawer is maximized. In addition, a noise reduction part is provided between a stopper member and a confining protrusion part constituting the rack gear assembly. Accordingly, although the stopper member collides with the confining protrusion part, impact noise is reduced and damage caused by the collision is prevented.
