Abstract: A gravity feed shelf capable of allowing a distance between a plurality of guide rails to be easily adjusted includes an upper shelf member having a pair of side frames, a pair of cross bars fixed on an upper portion of the side frames, respectively, a pair of junction bars fixed on a lower portion of the side frames, and a pair of guide fixing members, each being disposed on the cross bar. The guide fixing members are used to easily adjust the distance between the guide rails, thereby expanding the range of containers to be store therein. Further, the gravity feed shelf includes a lower shelf member having a pair of U-shaped channels and a plurality of plane members. Each of the plane members has a first surface with a plurality of projections with a relatively low contact area and a second surface with a plurality of projections with a relatively large contact area, the first or the second surfaces being selectively utilized depending on the weight of the containers to be stored.
