The present invention relates generally to improvements in filing tray structures, and more particularly to a novel tray device adapted for use in a fanning magnetic filing system. One embodiment of the invention as disclosed herein includes a tray structure wherein the bottom and sidewall sections are integral as well as non-magnetic. Endwall sections are interlockingly secured in a novel manner to the front and rear extremities of said sidewalls. An auxiliary index card or data sheet accommodating tray section having opposed upwardly flaring wall portions is located within the tray device. These flaring wall portions limit the extent to which the index cards or sheets may be tilted toward the front and rear of the tray device. The index cards have magnetic portions which cooperate with elongate magnets associated with the upright sidewall sections to effect fanning of the cards or data sheets.
