ABSTRACT:
A shelf unit assembled by joining a vertical member as a stud to a corner of a shelf or a chest, wherein the shelf unit is assembled with a shelf or chest in which the surface of the corner is formed into a corrugated surface of forming corrugation in a right-to-left direction, and a vertical member in which the surface of a portion to be joined with the corner is formed into a corrugated surface that overlaps the corrugated surface of the corner, whereby the shelf unit can be maintained always in a stable state without jolting of the vertical member or slack of the screw to facilitate assembling operation and reduce the cost.
