ABSTRACT:
The file tray comprises a plurality of superposed file boxes (1-3) interconnected by guide-rods (4-7) in such a way that an upper box can be spaced from a lower one. For the purpose of limiting their rotation, the guide-rods are provided with stop means comprising blocking ridges (16) on heels (4a-71, 4b-7b) joined to the guide-rods. The heels co-operate with rims projecting toward the guide-rods from the edges of the boxes.
