An apparatus for preventing pollution of walls in the parking zone of a public building is provided to shield the walls from exhaust gas of vehicles as a protective plate is lifted up from the wall when a vehicle is parked backward. An apparatus for preventing pollution of walls in the parking zone of a public building comprises an anti-pollution member(10), a fixed block(20), and a movable block(30). The anti-pollution member is composed of a fixed box fixed to a wall of the parking zone, a protective plate which is elastically supported by a spring in the fixed box and ascended/descended through the top opening of the fixed box to block the wall from the exhaust gas of a vehicle. The fixed block is fixed on the parking zone floor apart from the anti-pollution member, and horizontally penetrated with wires(14) connected to the protective plate. The movable block is located apart from the front side of the fixed block and connected with the other ends of the wires passing through the fixed block, and slides back and forth so that the end of a slider(31) which is inserted in the fixed block and elastically supported by a spring makes contact with the rear wheel of the vehicle parked rearward.
