PROBLEM TO BE SOLVED: To provide a fitting construction of option member enabling secure fitting/removing by a simple operation without requiring screws and nuts when the option member in a suspended condition is fitted to a shelf having a reinforcing part on an underside. SOLUTION: A connecting part X is formed between the reinforcing part 16 and the option member 3 for engaging them by sliding the option member 3 in one direction. A load of the option member 3 is supported on the reinforcing part 16 by the connecting part X in a position where the shelf 1 and the option member 3 are engaged. A limiting member 8 is removably fitted to the position between the shelf 1 and the option member 3 for limiting sliding of the option member 3 in the other direction.
