Abstract: An article storing tray convenient for various partitioning includes a tray. The tray has a tray body having a plurality of drop-in dovetail grooves and also has at least one comb-toothed partition board having a plurality of through dovetail grooves with dovetail tenons at opposite ends of the partition board. With this configuration, the partition board can be dovetailed in two drop-in dovetail grooves of the tray body. The tray further has at least one sub-partition board having dovetail tenons at opposite ends of the sub-partition board so that the sub-partition board can be dovetailed in any of the drop-in dovetail grooves of the tray body and any of the through dovetail grooves to the comb-toothed partition board. In such a tray, by dovetailing the comb-toothed partition boards and the sub-partition boards in the dovetail grooves, the internal space of the tray body can be divided into a variety of compartments and these partition boards can be securely held.
