Abstract: A tray device for a stroller comprises a tray body as well as, at each end of both ends of the tray body, a slider movable relative to the tray body, an operating unit for pushing away the slider, and an elastic member for pushing back the slider. When the operating units both are executed, the stakes of the sliders are respectively escaped from two armrests to enable the tray device being detached from the armrests. If only one operating unit is actuated, the tray device can be turned over.
