Abstract: A storage apparatus is installed in a vehicle with a flat bed and a tailgate and transforms back and forth between a collapsed configuration and an expanded configuration. The storage apparatus includes a container having a bottom panel, side walls, a lateral panel, and a top panel, a frame having a base board, side boards, support posts, slide rails, and bridge planks, and a slide member. The slide member connects the bottom panel of the container to the frame. The frame is fixed to the tailgate of the vehicle. In the collapsed configuration, the container sets on the tailgate or on the flat bed with the tailgate opened or closed. In the expanded configuration, the container cannot set on the tailgate with the tailgate closed, but the container can set on the tailgate with the tailgate opened. Opening the tailgate allows access to the storage space.
