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 D.sub.1 of the cylindrical portion 6 is larger than an inner diameter D.sub.2 of the outer tubular portion.
