摘要

PURPOSE: A cover for preventing a leak from sides of the nozzle device is provided to minimize or prevent the leak occurrence of the coating liquid from the nozzle device by tight coupling or airtight joining with the elastic material of the inner cover block. CONSTITUTION: A cover for preventing a leak from sides of the nozzle device (220) comprises a pair of cover blocks (240) installed in both sides of the nozzle device. The above a pair of cover blocks comprises: the inner cover blocks including the respective inner body part (242) and protrusion part (242b); an external body part (246) including a first and second accommodating part; a plurality of first joint holes (248a) formed in order to tightly couple the above inner body part to a first outer surface of the same; and an outer cover block including a plurality of second joint holes (248b) formed in order to tightly couple the above outer body part to a second outer surface of the above nozzle device.
