PROBLEM TO BE SOLVED: To provide a retractable closet shelf capable of recognizing where the adjusting auxiliary legs are at any time, preventing them from being lost and to fulfill users requirement that it would provide wider application if the height of the closet shelf is adjustable and can be used directly on the floor so as to reinforce the top board. SOLUTION: Receiving parts to support auxiliary legs for adjusting height are provided near both edges of the side bars connecting with main legs, not to interfere the fitting of the main legs. The auxiliary legs are located in the receiving parts when they are not in use, allowing user to recognize easily where they are and preventing the legs at least from being lost. By engaging only the main legs with the main body, it can also be used as a floor grates in a low height. Issue of strength for weight of a resin molding is solved by molding it inserting a rectangular steel pipe into the resin, which provides both load-carrying capacity and resistance to rust.
