A frame body water-proof structure, has a main frame body, a frame cover, a loop-shaped elastic packing element, and four securing screws for fixing the frame cover on to the main frame body. A wall portion is formed along a periphery edge portion on an engaging surface of the main frame body, and a shoulder portion is formed continuously in connection with the wall portion. The packing element is attached around the outer periphery surface of the wall portion and mounted on the shoulder portion. A recess portion is formed on the inner side of the periphery edge portion on an engaging surface of the frame cover. The recess portion also including a shoulder portion. When the recess portion of the frame cover is engaged on to the outer periphery surface of the wall portion of the main frame body, a space for accommodating the packing element is formed as defined by the recess portion of the frame cover, the outer periphery surface of the wall portion, and the shoulder portion of the main frame body, such that as soon as the frame cover is fixed on to the main frame body by the four securing screws, the packing element is elastically deformed so as to seal the space.
