<p>PROBLEM TO BE SOLVED: To pass cables having different diameters through inserting holes foamed through the base section of a spacer for cable without gap, by providing a cylindrical projecting section on the peripheral bank of the opening of each inserting hole and, at the same time, making the inside diameter of each inserting hole smaller toward the front end in the projecting section. SOLUTION: On the surface of a base section 8b of a spacer 8, five projecting sections 8c are arranged. Each projecting section 8c is formed in such a way that the external size of the section 8c is changed in three steps, with the size being made smaller as going toward the front end. In addition, inserting holes 8d extended over the rear surface of the base section 8b are also formed so that the inside diameter of each hole 8b may change in three steps, with the diameter being made smaller as going toward the front end side. Therefore, when each projecting section 8c of the spacer 8 is cut along one of single-dot chain lines A-C, the intrusion of dust, etc., into a protective cover can be prevented, because the inside diameters of the inserting holes 8d can be changed in three steps and three kinds of branch lines 3 can be passed through the holes 8d without gap.</p> |
