<P>PROBLEM TO BE SOLVED: To provide a water cutoff rubber plug which deals with coated electric wires having different outer diameters in the cylindrical water cutoff rubber plug which is disposed between a metal intermediate cap covering a core wire exposed part, where a coating layer of a coated electric wire terminal is removed and the core wire is exposed, and the coating layer near the core wire exposed part and the coating layer and maintains the core wire exposed part in a watertight state. <P>SOLUTION: A water cutoff rubber plug is provided with a small inner diameter part and a large inner diameter part having an inner diameter larger than the small inner diameter part. A small inner diameter part lip part, contacting with a coating layer of a coated electric wire which is inserted into the water cutoff rubber plug and maintaining a space between the coating layer and the water cutoff rubber plug in a watertight state, and a large inner diameter part lib part, maintaining the area between the coating layer and the water cutoff rubber plug in the watertight state when contacting with the coating layer of the coated electric wire which is inserted into the water cutoff rubber plug, are respectively provided at an inner side surface of the small inner diameter part and an inner side surface of the large inner diameter part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
