<p>A harness grommet includes an inner tubular portion 3 , provided within an outer tubular portion 2, and a flexible portion 4 extending from the inner tubular portion in a flaring manner. The flexible portion is turned back into the outer tubular portion to form a sound-insulating air layer. A cylindrical portion 6 extends from the flexible portion 4, and an inverting folding portion 5 is formed at the boundary between the flexible portion and the cylindrical portion, and a sound-insulating membrane 7 is formed by the flexible portion and the cylindrical portion. An outer diameter D1 of the cylindrical portion 6 is larger than an inner diameter D2 of the outer tubular portion. <IMAGE></p> |
