PURPOSE:To make it possible to display and sell commercial goods which are left to be on-vehicle,by fitting an inner box telescopically in an outer box on a box-shape track, having a volume occupying one-half of the outer box in the longitudinal direction of the outer box, and by extending and retracting the inner box as necessary. CONSTITUTION:In a box-shape track, an inner box having one side surface commonly used with an outer box and the other side surface opened is fitted in the outer box 1 within the volume occupying the longitudinally one-half of the outer box 1. Further, the inner box 2 is extendably and retractably coupled to the outer box 1. That is, rails 3 are attached at the outside of the four corners of the inner box 2 and, rollers 4 are attached to the floor and ceiling of the outer box 1 to support the rails 3. Further, reciprocatable hydraulic cylinders 4 are laid on the floor of the outer box 1 and is connected through pipe linges 7 with a hydraulic pump 6 driven by a generator on an engine while a piston rod 8 in the hydraulic cylinder 5 is connected to the lower side of the inner box 2. Meanwhile racks for displaying goods are arranged on one side in the outer box 1 and in the inner box 2, respectively. |
