A rack apparatus comprising: stationary rails attached on side walls of receiving space; traveling rails horizontally sliding on the stationary rails; a fore arm and a rear arm hinged on each of the traveling rails as to turn around one way or other; a stopper having an arc-shaped linkage groove and being hinged on each traveling rail as to be freely turnable about a hinged portion; a protrusion formed on the stopper in vicinity of such hinged portion, the protrusion being engaged with the respective stationary rail to block downward turning of the stopper during sliding on the stationary rails and then leaving out from an end of the stationary rail to allow downward turning of the stopper; a guide pin protruding from the rear arm to engage with the linkage groove, and being shifted to a lowermost position of the linkage groove to allow downward turn-wise shifting of a distal end of the rear arm in accordance with downward turning of the stopper; a rack support connecting the fore and rear arms; and a rack container supported on the rack supports, said rack container being able to be shifted forward by the traveling rails and then be shifted downward and upward with keeping its horizontal posture, by turning of the fore and rear arms.
