<p>PROBLEM TO BE SOLVED: To enhance versatility enough to cope with a wide variety of cable diameter and the shape of cable inlets and the efficiency of sealing work, by forming a shape adjusting section that adjusts the lap length in the radial direction, that is, the direction of winding, of the base portion and tip portion of an elastic body adaptor section almost of whirl shape, and thereby adjusts the shape of circumferential surface and cable insertion hole. SOLUTION: A shape adjusting section 10 almost of whirl shape that adjusts the diameter of a circumferential surface 6 and a cable inlet 8, is formed in an elastic body adaptor section 9. In proximity to the cable inlet 8 of the shape adjusting section 10, its base portion 2 is gradually Increased in thickness toward its tip portion 3. In proximity to the circumferential surface 6 its tip portion 3 is gradually increased in thickness toward the base portion. This makes it possible to adjust the lap position of the base portion 2 and the tip portion 3 according to the diameter of a cable 7, and to adjust the diameter of the circumferential surface 6 and the cable inlet 8 according to the diameter of the cable inlet 5 and the cable 7. This significantly improves the versatility and the efficiency of installation work.</p> |
