Abstract: A cup holder device capable of reducing the size of a cup holder body and enabling a tray to be drawn in and out from the body in a narrow space by folding the tray into two parts. The device includes a body having an opening formed on a front portion of the body, an inner tray for being drawn in and out of the body through the opening, an outer tray installed on a front portion of the inner tray so that both the inner tray and the outer tray provide at least one cup seat, and a hinge section for folding the outer tray over the inner tray so that the inner and outer trays in a folded state are received in the body.
