ABSTRACT:
A waterproof structure for an electric wire drawout portion is low in manufacturing cost and enhanced in waterproofness. A cover portion is formed on an end portion of a housing and on this cover portion there is mounted a lower rubber-like elastic member. An upper cover portion is welded to the cover portion by ultrasonic oscillation and on the upper cover portion there is mounted an upper rubber-like elastic member brought into pressure contact with the lower rubber-like elastic member and an electric wire. On the cover portion and the upper cover portion there are integrally formed lower and upper projections exposed on surfaces of the lower and the upper rubber-like elastic member. When welded together by the ultrasonic oscillation, the upper and the lower rubber-like elastic member are closely contacted with each other in a state of their being compressed and simultaneously the upper and the lower rubber-like elastic member are closely contacted with the electric wire, the cover portion and the upper cover portion and the projections are welded to each other.
