A goods display rack comprising: at least one goods transfer unit configured to transfer a product mounted on a top surface thereof to a withdrawal position; a front fixing profile disposed on the front of the goods display rack, and configured to attachably/detachably fix a front end of the goods transfer unit; and a rear fixing profile disposed on the rear of the goods display rack, and configured to attachably/detachably fix a rear end of the goods transfer unit, wherein the goods transfer unit is configured to slide from side to side in a position adjustment area between the front fixing profile and the rear fixing profile, with the front end and the rear end thereof mounted respectively to the front fixing profile and the rear fixing profile, wherein a recess is formed into the bottom surface of the goods transfer unit, extended along the left and right directions of the goods display rack, and wherein the front fixing profile comprises: a front end support plate supporting the front end of the goods transfer unit upward, under the goods transfer unit; and a protrusion configured to protrude from the top surface of the front end support plate, extended along the left and right directions, and to be inserted into the recess of the goods transfer unit, wherein the recess comprises a bottom surface, and two opposite surfaces facing each other, with the bottom surface in between, and a flange is formed on a top end of the protrusion, characterized in that bumpers are formed apart from each other on the two opposite surfaces, extended along the left and right directions of the recess, and wherein when the protrusion is inserted into the recess, the front end of the goods transfer unit and the front fixing profile are engaged with each other by forced insertion of the protrusion into the recess through temporary friction between the flange and the bumpers, and when the protrusion is detached from the recess, the front end of the goods transfer unit and the front fixing profile are separated from each other through temporarily friction between the flange and the bumpers. at least one goods transfer unit configured to transfer a product mounted on a top surface thereof to a withdrawal position;
