PURPOSE: A sectional shelf frame is provided to prevent the movement of the frame in all directions by tightly fastening the coupling parts of horizontal and vertical members, thus improving the stability and coupling strength of the sectional frame. CONSTITUTION: The sectional shelf frame consists of a plurality of vertical members(10) formed with fastening holes(11) in a longitudinal direction at regular distances, and a plurality of horizontal members(20) formed with hook type holding pieces(21) on the both ends thereof so as to be fitted into the fastening holes. The inner cross section of the holding piece is inclined outward toward the bottom thereof, so that the inner and outer cross sections of the holding piece can grip tightly the wall of the vertical member when the holding piece is fitted in the fastening hole.
