Abstract

A rubber plug for a water-proof connector has an inner cylinder and an outer cylinder. The rubber plug into which an electrical wire inserted and which is inserted into a cylindrical structure of the water-proof connector sealingly closes the gap between the electrical wire and the cylindrical structure. The inner cylinder is provided at a portion which is positioned near the opening of the cylindrical structure of the water-proof connector, for sealingly closing a gap between the electrical cylinder and the inner cylinder. The outer cylinder has an annular groove, and is provided outside the inner cylinder at the portion in such a manner that the outer cylinder surrounds said inner cylinder through the annular groove for closing a gap between the inner cylindrical surface of the cylindrical structure and the outer cylinder.
