Abstract: A drawing part of a cable 3 in a waterproof case for an electrical apparatus is sealed. On an outer circumferential part of the cable 3, a first bushing member 2a and a second bushing member 2b are formed by injection molding to be spaced with respect to each other. A box part 35 of the waterproof case is located between the first busing member 2a and the second bushing member 2b. After locating the cable 3 in the waterproof case, a filling material 40, such as epoxy resin or urethane resin, is filled into the inside of the box part 35.
